Exercise Physiology

The paper discusses five articles related to exercise physiology. Within these articles, a number of topics are comprised, including: exercise in extreme environments, optimizing performance in sport, gender and age as they relate to exercising, fatigue during exercise and health. These topics will be examined as per the points-of-view presented in the articles below.

Icy Climb to the Sky in Summery Yosemite by Bill Becher (Source: )

This first article discusses the topic of exercise in extreme conditions. Here, the extreme conditions are cold, snow and ice, and the exercise is ice climbing in Yosemite National Park. The article begins by describing the conditions with which one must put up in this extreme sport, which include frigid temperatures and, sometimes, superhuman strength, as one dangles hundreds of feet, even thousands, above the ground. The article, however, relishes in this latter facet, and even applauds those who undertake such…… [Read More]

Exercise Physiology

Exercise Physiology: learning about it, involving oneself in it or obtaining gainful employment from it is becoming a part and parcel of most people's life. With improvements in technology, our lifestyles have become sedentary. Such lifestyles also put us at greater risk for diseases. This work will be concerned with a general idea of exercise physiology with information for all who want to involve themselves with it.

Simply put, exercise physiology (EP) is the identification of physiological mechanisms that underlie any physical activity. (Amundsen, 1981) and hypertension should be closely monitored. While maintaining a regimented lifestyle with optimal levels of physical activity can be helpful, over-exercising can be detrimental. Exercise physiology therefore, also involves professional guidance and counseling.

In 1997, the American Society of Exercise Physiologists (ASEP) was founded. (CSS.edu, Professionalization of Exercise Physiology Online, 2003) few universities have ASEP accredited bachelors and masters degree programs in exercise science. Some…… [Read More]

Attitude Toward Diet and Exercise

In fact, she already had all of that information written in the margins right next the photographs. Every picture had a description of how many calories, and how many grams of protein, carbohydrates, and fats she consumed in between the consecutive pictures. She explained that her diet changed much more than her training during that time and I was very surprised at the difference that could be seen so clearly from picture to picture, and especially at the differences in her physique and muscularity from the beginning to the end of each contest preparation cycle. According to her, she maintains the same basic workout routine all year long and the real difference that accounts for the extreme changes in her muscularity before contests is almost exclusively a function of her diet.

Psychological and Physiological Effects of Exercise on the Mind and the Body

Exercise has been described as the best medicine for depression. It can help a person get through rough times. Physical exercise is very important for a person's mental and physical health. Exercise helps in pumping more blood through the veins. This results in the increase in size of the arteries and it prevents fats from clogging the arteries. It also prevents blood clots. A person who exercises regularly is protected from a variety of diseases and it helps in curbing cholesterol. Exercise benefits a human body as it lowers blood pressure and conditions the lungs. Exercise has its various advantages. It successfully counters stress, depression and anxiety. It has been named as the best fighting force for all these problems. Exercise is also instrumental in improving a person's nervous, cardiovascular and immune system. It also increases our metabolism, digestion and stimulation.

Electromyography Biopac Exercise Discussion This

The authors were trying to develop a system of estimating and indexing muscle fatigue rates during static muscle contraction. The results of this study indicated that estimations were reasonably successful with some limitations that were noted. One limitation was that the study neglected muscle recovery since the experiment was performed in a lab under controlled conditions and the muscles were able to fully recover. However, in the real world muscles move in a dynamic environment thus making muscle recovery rates a challenge in producing an accurate estimate of fatigue.

Another study looked at the efficacy of treatments in patients who suffer from Carpal Tunnel Syndrome (CTS). The study conducted research using 111 patients who suffer from CTS. They compared the standard conservative treatment (SCT) with other forms of treatment available that also propose to alleviate symptoms associated CTS. They found that SCT, which includes local steroid injections, was effective as…… [Read More]

Energy Sources for Physical Exercises

Health Fitness Human Performance

One of the most important parts of an athlete's training regime is nutrition because of its role in human performance. Athletes need to focus on nutrition because the failure to ingest adequate calories can contribute to a lack of vital macro and micro nutrients. Moreover, nutrition is a crucial element in any athlete's training regime given the influences of food on a person's physical mankind. Throughout history, certain foods have been regarded as essential in preparation for strenuous physical activity or exercise. As part of focus on nutrition, athletes need to consider various factors that contribute to nutrition in relation to physical activity and exercise. Some of these important considerations include certain types of food and food sources that help in preparation for physical activity, heath, fitness, and human performance.

Air Force Tactical Force to Force Exercise

Air Force Military Training 4
Aviation Tactical Force- to- Force Exercise
Military operations entails an interaction of multiple forces, hence sequencing their interaction during training is essential in promoting inter-service cooperation (Col Gopaul, 2017). Efficiency in training is determined by how well the training mirrors the battlefield. The sequencing of the battlefield is configured engaging in multi-service training exercises referred to as force- to- force exercise.
Force- to- force exercise training is a form of training that entails training with simulation equipment to realism to training as the training. Tactical force-to-force exercises essentially entail simulation and configuration of battlefield complexities to support basic training of pilots, mission commanders, and operators. The operation entails the interaction of technologies and forces with different operation experience (Kishore, 2017). The simulated exercises ensure warfighting competencies and swift execution and successful spectrum of operations as well as interforce relationship building (Col Gopaul, 2017).

Physiological Effects of Endurance Training

Physiological Effects of Endurance Training

Endurance training produces many physiological changes, both during training and after the training period is complete. These changes are biochemical and also involve changes in the cardio-pulmonary system. The correct way to perform endurance training has been a subject of controversy in recent years. There are many differences in training methods. These differences and the effects of endurance training will be the subject of this research. The jury is still out as to what constitutes the perfect duration and intensity of training program.

Studies have shown that a focused training program can increase maximum oxygen intake by 15-30% over a three-month period (7) and that can increase to 50% if the training is sustained for over 2 years. The body makes many metabolic adaptations as well. These adaptations drop rapidly in the first few weeks after training is stopped (1).

Biomechanical Principles

Biomechanics is the study of mechanical and physics principles in relation to motion in sports. Every sport has its biomechanical theories and each one is specialized to that particular skill with equations derived from Newtonian physics and knowledge of the human body and its capabilities. When combined and properly practiced, biomechanics can improve an athletes overall performance, making the athlete superior to their competitors.

The freestyle arm-pull in swimming is a precise study in the art of biomechanics introduced for an efficient result. It is an established fact that water is 773 times as dense as air and 55 times as viscous (Miller, 1975). What this means is that planning an efficient stroke in water is going to require greater strategy than planning an efficient stroke in air. The primary factors that go into creating the ideal stroke in swimming are vectors, motion, force, work, and…… [Read More]

career of an athletic trainer, including the background necessary for the career, the necessary education, and job opportunities for athletic trainers. Athletic trainers form a necessary backbone of most professional sports organizations, and many private organizations. A professional athletic trainer can make the difference between a life-changing injury, or returning to the game. Athletic trainers are an essential and integral part of modern sports medicine, and as sports and athletics increase in importance in our society, they will continue to play an important part in our healthy lives.

Athletic trainers have been around for centuries, but today, most trainers are certified, and not only work with sports clubs or educational facilities, they can work in gyms and fitness centers, and even corporate workout centers.

Certified athletic trainers (ATCs) are medical experts in preventing, recognizing, managing and rehabilitating injuries that result from physical activity. Athletic trainers can help you avoid unnecessary…… [Read More]

Acclimatization Ascending to Higher Altitudes

(1989). These researchers investigated skeletal muscle adaptations in response to acclimatization at high altitude. Samples of muscle extracted before reaching high altitude and after returning to sea-level showed that maximal activities of enzymes, such as those representative of beta-oxidation, were unchanged. However, after exposure to extremely high altitude hypoxic conditions, reductions were observed in succinic dehydrogenase, citrate synthetase and hexokinase. The findings of this study did not support the researchers' hypothesis that extremely hypoxic conditions elicit changes that are adaptive toward maximizing oxidative function at the intracellular level (Green et al., 1989).

Ephedrine Abuse the Use of

However, these studies did not separate the effects of ephedrine from that of caffeine and so more intense research is awaited in this direction. [Robert a] it is to be noted that caffeine and ephedrine work synergistically which could be dangerous in patients with pre-existing cardiac or blood pressure abnormalities. Caffeine affects the adenosine-mediated dilation of blood vessels by antagonizing its receptors. The resulting increased availability of free adenosine monophosphate furthers the activity of ephedrine and catecholamine stimulation resulting in reduced cardiac refractory periods and increased cardiac output and consequently elevated blood pressure. [Charles N. Krome]

It is necessary to look into the inherent risks associated with the use of ephedrine. Ephedrine has a very high percentage of adverse reactions compared to all other herbal supplements. As reported by ent et al. (2003), ephedrine alone accounts for around 64% of all adverse medical reactions due to herbal products. This in…… [Read More]

B Cells T-Cells Hemoglobin

Deliberately reducing the amount of PO2 circulating in the breathable atmosphere around a person -- such as Kara accomplishes at sea-level with her tent -- ultimately produces a lowered rate of hemoglobin oxygenation in the arterial blood. This condition, hypoxia, can be dangerous and can, of course, impair aerobic physical exercise -- however the trick that Kara is taking advantage of is the body's ability to undergo acclimatization, in which the body's physiology and metabolism will engage in adjustments that improve the body's ability to tolerate the low-PO2 levels through different means, such as adjusting its own acidity (to change the level of interior biochemical reactivity in order to boost absorbable oxygen levels) but also -- more importantly for Kara and her endurance training -- by improving metabolism on the cellular level and blood circulation (to maximize the value of the oxygen actually obtained) and, most importantly, by "increased synthesis…… [Read More]

Military Readiness the Issue of

In addition, the Marines have a much smaller force than the army.

On the other hand, the army cannot be as selective as the marines because it needs to maintain a much higher number of troops. The article explains that the army "needs 80,000 new soldiers this year and must find them in a populace that is in many ways less willing and less able to serve than earlier generations were (Mockenhaupt, 2007, pg.86)." The article explains that teenagers and young adults are overweight and less fit than any previous generation. In addition, this generation of young Americans eats more unhealthy foods, watches more television, and engages in less physical activity than previous generations. The article further asserts that this generation is "more individualistic and less inclined to join the military. And with the unemployment rate hovering near historic lows, they have other choices (Mockenhaupt, 2007, pg.86)."

Career in Sports Nutrition Including the Background

career in sports nutrition, including the background necessary for the career, the necessary education, and job opportunities for sports nutritionists. Sports nutritionists can help people from every way of life lead healthier, happier lives. A professional sports nutritionist studies nutritional needs, weight maintenance, and even eating disorders so they can understand the nutritional problems American's face, and help them make the right eating decisions for their own specific needs. ith the growing problem of obesity in America, it is clear sports nutritionists will become even more valuable in the future. Today, they are an essential and integral part of modern sports exercise, and as the nutritional needs of our society continue to alter, nutritionists will play an even more important role in our healthy lives.

Sports nutrition is a relatively new field, and so many professionals are creating their own opportunities in many areas of exercise science and related sports…… [Read More]

Overarching Goal of This Study

Good researchers tend to pull methods out of a tool kit as they are needed" (2006, p. 54). Notwithstanding these criticisms and constraints, though, most social researchers seem to agree that classification by some type of research paradigm is a useful approach based on the need to determine which approach is best suited for a given research enterprise. In this regard, Corby concludes that, "The contested nature of research makes it impossible and unhelpful to ignore the different aims and purposes of various research projects and the methods and approaches being used to carry them out" (2006, p. 54). Therefore, the different aims and purposes of the positivist research paradigm, the constructivist research paradigm and the pragmatic research paradigm are discussed further below.

Nursing Knowledge A Controversy the Scope of

Nursing Knowledge: A Controversy

The scope of the nursing profession has increased dramatically over the last thirty years. The demarcation between medical and nursing tasks is quickly dissolving as the nursing profession is becoming increasingly multidisciplinary and complex. In 1996, nurse practitioners were mandated to obtain master's degrees to address their changing role in medical care (Nicoteri & Andrews, 2003). In this multidisciplinary and evolving healthcare environment, adaptation is paramount to providing effective patient care. Currently, there is a controversy in nursing regarding the direction that the development of nursing knowledge should take. There are many critics who believe that developing new nursing theories is an effective way to promote this development. However, theories are often abstract and not adaptable to specific healthcare settings. The belief that the knowledge base for nursing should evolve entirely from theory has important implications for nursing as an academic discipline and by extension the…… [Read More]

Exercise and diabetes: Beneficial effects

Diabetes is increasing in the United States and throughout the world due to the ever-growing adoption of an unhealthy lifestyle, including poor diet and lack of physical activity. Obesity is a characteristic often present in individuals with diabetes, and in order for the occurrences of diabetes to be reduced and the effects of diabetes to be minimized, efforts must be put in place to encourage weight loss and the maintenance of a healthy weight. It is expected that obesity and diabetes will reach epidemic proportions unless prompt action is taken to counteract these conditions (Albu & aja-Khan, 2003).

Lifestyle factors have been identified that are associated with glycemic control and body mass in individuals with diabetes. Grylls et al. (2003) found that reducing dietary saturated fat and excess body weight may be useful for improving glycemic control in older adults with…… [Read More]

Practical esearch Finding Implementation and Experimentation Stage -- Phase I

The experimenter did not set out to determine specifically which of the various contributing factors (or combinations of factors) identified by the empirical research of medial tibial stress syndrome was most responsible for the experimenter's symptoms. However, since the initial attempts to resolve the symptoms incorporated changes to all of the external variables except a change in running surface, the experimenter immediately sought a softer running surface and temporarily abandoned running on any hard surface that magnified instead of minimized the physiological trauma associated with running on harder surfaces.

Because the empirical research also implicated poor running stride mechanics and excessive vertical elevation, the experimenter devoted considerable attention to making the following specific changes to the running stride: (1) shorter strides to minimize travel of the body while neither foot is in contact with the running surface; (2) conscious attempts…… [Read More]

Houdini Was Able to Modulate His Normal Physiology During His Stunts

The objective of this study is to examine how Houdini was able to modulate his normal physiology during his stunts.

Harry Houdini caused the world to marvel at his skill in escaping the bondage of handcuffs and was referred to as the 'handcuff king' and as well Houdini performed many other magic tricks that required more than merely illusion but instead required that he be able to alter his own body's physiology. The modulation of physiology enabled Houdini to accomplish great feats and to capture the imagination and attention of a large base of fans across many years. Houdini is well-known for having spent a great deal of time and effort to invalidate individuals who were so-called mediums communicating with the dead because he detested this type of trickery.

However, in almost 30% of HCM cases only one segment of the left ventricle develops hypertrophy. The patterns of LV wall thickening is also diverse as is the thickness of the LV, which ranges from anywhere between 21 mm (average) to even 60 mm in some patients. It remains a sad fact that screening programs in the form of preparticipation evaluation based on familial history and electrocardiography does not reveal much. A recent study showed that a preparticipation screening for 115 high school and college athletes who later succumbed to sudden death could identify only 3% of them as at risk. This study also revealed that LVH is very mild and not obvious in adolescents and therefore electrocardiography readings are not diagnostically conclusive. [Maron]

52 Week Soccer Training Program

Introduction

Soccer is a true total sport. It requires of its players the ability to show intense bursts of speed and power while simultaneously commanding the ability to conserve energy and endure for the complete span of the game. It requires athleticism, strength, and agility. Players must be conditioned at a top level to be competitive. That is why training for 3-5 days a week is essential in every season for players. To avoid injury, pre-season and off-season training is also vital (Heidt, Sweeterman, Carlonas et al., 2000). The sheer physicality of the sport requires its athletes to stay in shape throughout the year.

Every soccer training program should be tailored to the meet the needs of the individual (Manzi, Castagna, Padua et al., 2009). This program is designed for a 185 lb, 15 year old male high school soccer midfielder. It is developed for off-season, pre-season and in-season programs…… [Read More]

Cardiac Health and Lifestyle

incidence rates of childhood obesity are linked to socio-economic factors. Core drivers of obesity in both children and adults are diet and exercise, and research has shown that a calorie is not a calorie. That is to say that certain foods serve as triggers for metabolic responses and physiological events that impact the overall health of individuals. The old adage that people can focus on loosing weight -- the associated implication is that they will be healthy as a result -- has shown not to be true. Much of the prepackaged food consumed today -- particularly so-called junk food -- is high in sugar, fats, and calories. However, this statement is too reductionist to be of help to people who are interested in improving their diets in order to actually become healthier.

ecent research indicates that obesity is certainly a factor in the incidence of diabetes, as is total caloric…… [Read More]

Cardiac Arrest

elationship between cardiac arrest and coronary cardiac disease

The heart is an essential organ in the human body, it keeps the individual alive. Understanding how the heart operates and functions is essential to help protect your heart from heart disease. Cardiac arrest and coronary heart disease are significant heart related illness that has a high mortality rate. It is important for individuals with pre-existing heart disease to understand the symptoms of cardiac arrest and coronary heart disease, since these are both leading causes of fatality in the United States. Understanding how the heart works, the individuals risk for heart disease, and how to prevent or delay heart disease is essential. In this paper I will address the relationship between cardiac arrest and coronary heart disease. I will also explain how the heart functions and discuss some ways of preventing cardiac arrest and coronary heart disease.

NPR Health and Science Special

Silk and tassel look similar but the two structures are functionally different. The NP interviewer uses them synonymously without correction by the farmer.

However, the farmer is correct in emphasizing the importance of the silk and tassel, the stigma and the male inflorescence, in the reproduction of the corn. Moreover, the farmer stresses the relationship between wind and corn fertilization. Pollen grains are "borne in anthers, each of which contains a large number of pollen grains" that emerge only during certain morning hours (Thomison). The farmer in the NP segment fails to mention the crucial timing involved in corn pollination.

Corn ovules are potential kernels, which are the fruits of the corn. The seeds of the corn are its pollen: which is created in the anthers and which travel along the male inflorescence to fertilize the stigmas. Stigmas are essentially pollen receptors. In many plants, the stigma is part of…… [Read More]

Sports Science

Motor learning and motor control is a field of science that is being studied from a sports point-of-view. Motor learning is connected to all the processes and conditions that affect one's ability to acquire skills, while motor control ascertains neuromuscular performance of individuals. Many people are taking great interest in the learning of motor skills and expertise, and the development of coordination. This new field of sports is based on the use of the knowledge base in the movement and sport sciences, cognitive sciences, and also physical therapy.

1. The dilemma of Obesity

Mokdad et al., (1999) in his study found that the issue of unhealthy weight, overweight and obesity are perhaps one of the rising concerns for the Americans in the 21st century as more and more U.S. citizens become vulnerable to the circumstantial risks and dangers of the phenomenon (Mokdad et al., 1999). It is usually the body mass indexes (BMI) that indicate whether a person is actually overweight or not. The National Health and Nutrition Examination Survey (NHANES) carried out a study for the years 1999 to 2002 using the BMI phenomenon and concluded that about 65% of U.S. citizens in the adulthood years were categorized under the overweight group because of their BMI (Division of Nutrition and Physical Activity, National Center for Chronic Disease Prevention and Health Promotion, 2005).

Women and Weight Training -No

)

Further, within this essay I have explained key reasons for how and why women's mere building of healthy muscle through appropriate weight-lifting exercise will not in fact make women "bulk up" (and that in order to do so, women must in fact weight train in a particularly rigorous and deliberate way, one that average female weight-lifters simply do not). Instead, weight-lifting allows most women who exercise regularly and correctly in this way to become healthier, more physically fit, more physically attractive, and therefore to like themselves better and gain greater self-confidence. Women who have been holding back from weight-lifting due to the unrealistic fear of building too much muscle may now, therefore, relax about this faulty myth, pack their gym bags, and head fearlessly toward those barbells and/or Nautilus machines!

Food Factors

There is an over-abundance of food availability in America's supermarkets and restaurants, particularly fast-food restaurants (Hill and Peters, 1998). The portion-sizes of food in America's restaurants are unreasonable and uncontrolled (Hill and Peters, 1998). There is an increase in consumption of sugar-sweetened sodas and sweetend food (Bray, 2004). There is also an over-abundance of high-fat food choices paired with a lack of palpable low-fat choices. Most importantly, studies show that a diet of 35% fat or higher contributes to obesity in sedentary animals (Hill and Peters, 1998). It is no wonder that children having this unnutritious food become obese.

Skin Blood Flow Thermoregulation Is

The picture to the left depicts the various elements that are responsible for thermoregulation in human skin. The illustrations shows the various layers of skin along with the veins, arteries and capillaries of the circulatory system that assist in insuring that the thermoregulatory system works properly. The sweat glands are responsible for selectively removing materials from the blood the sweat glands then concentrates or alters these toxins, and secretes them for elimination from the body. The perspiration or sweat is then removed through the sweat pore. This has a twofold purpose: to remove toxins and thermoregulation (in this case cooling the body).

Thermoregulation involving perspiration is brought about by both internal and environmental heat and exercise. As it relates to the latter, there have been many studies related to exercise and thermoregulation. According to Marino (2004)

Lungs What Are the Lungs

However, it was 1953 that the formation of serotonin was from the lungs was substantiated. It is also observed that detoxification of the blood takes place in the lungs. Later, it was observed that one of the important activities of the lung is to provide chemical filtration by shielding the regular circulation of blood from the attack of vasoactive mixtures and other exogenous compounds present in the arteries. The physiology of the lungs and its location makes the lung exclusively suitable to perform these activities. (Wet; Moss, 1998)

The total output from the cardiac system is obtained by the lungs whereas other organs acquire only a very small quantity of output. The blood that circulates the lungs is subject to the vast capillary endothelial plane of the body which is of seventy square meters. This aspect of output and circulation enable the lung to perform the efficient function of biochemical…… [Read More]

Diabetic Vascular Disease

Diabetic Vascular Disease state caused by the deficiency of a chemical in the body called insulin which is a hormone is called Diabetes. There are two forms of diabetes. In the type-one diabetes no insulin is formed and people require insulin injections for existence. This was once thought it would affect only children, but now it can occur at any age. The type2 diabetes is due to the resistance of the body towards the effects of insulin. This also includes insulin which is insufficient. ut in this type there is some amount of insulin produced. In both the types the blood glucose levels is increased. When compared to people without diabetes, people with diabetes are prone to certain problems. These problems occur in the nerves (neuropathy), kidney (nephropathy) and eye (retinopathy). These people are prone to early heart attacks and stroked due to the hardening of the arteries (arteriosclerosis). With…… [Read More]

Alzheimer's Disease According to the

One of the most common mental disorders linked to Alzheimer's is depression which according to Elwood Cohen manifests itself in three important ways. First, "There are higher rates of depression among Alzheimer's patients than among non-demented adults;" second, "Having a depressive episode is associated with an increased risk for developing Alzheimer's," and third, Depressive symptoms can be confused with dementia in older adults" (1999, 214).

In a recent study conducted by the Cardiovascular Health Initiative, based in Washington, D.C., more than one-third of 400 dementia patients and more than one-fifth of 300 patients with mild cognitive impairment (MCI) had experienced symptoms of depression during a one-month period prior to the study. Similar results were reported by the Multi-Institutional esearch in Alzheimer's Genetic Epidemiology (MIAGE) which discovered that "In the year prior to a patient being diagnosed with Alzheimer's disease, the same patient was almost five times more likely than their…… [Read More]

Wrestling and Football Women in

Apart from physical aptitude, societal roles also play a large role. Says Susan Birrell in omen, Sport, and Culture, "it is also clear that sport is strongly associated with the male identity, with being popular and having friends. Rugby and football are archetypical here" (Birrell 35). The bonding stereotypes of the female gender are generally non-physical, and thus sports do not have as positive an association for women. As a result, of that percentage of women that are able to compete at the same level as men in contact sports never enter the arena in the first place.

Regardless of the reason, very few women get involved with contact sports, and practicality makes it difficult for those who are interested to be accommodated. Separate locker room facilities are necessary, and the team dynamics are altered fundamentally as the issue of sexual tension enters the scene. There are some who would…… [Read More]

Manipulative Thrust Techniques in Lower

The practice of manipulative thrust therapy can be dangerous and cases of injuries and tragic events have been recorded. Cases of vertebral artery dissection (VAD) have been recorded in people that had the cervical spine manipulation technique done and research on the cases from 1966 to 1993 concluded 30% could be attributed to the procedure (Cleland 2007). VADs are spontaneous and can be normally present at the initial onset of headaches or neck pain. This represents the conclusion that the VAD was present before the technique is performed on a patient complaining of neck pain. The debate over the truth is still being waged. Even authors have joined the debate but they are touted as biased and do not support the evidenced based in research (User's Guide 2008).

Other debates rage as well. The risks of the manipulative thrusts therapies are actually no worse the risks from NSAIDs and cervical…… [Read More]

Healthy Heart vs Coronary Disease

hen an heart needs more oxygen, such in times of exercise, stress or pharmacological stimuli, blood flow is increased to fulfill this demand. However, the physiological narrowing of arteries due to plaque build up found in coronary disease restricts blood flow to the heart, especially in times of when an increase in myocardial oxygen is needed. These restrictions mean a lessened CFR for the individual, which can lead to coronary ischemia, cardiac infarction, and several other dangerous effects. This physiological change in the coronary system, through the build up of plaque, occurs for several reasons. Lack of physical activity and poor nutrition, with the consumption of certain fats and cholesterols, can facilitate plaque build up. High blood pressure, obesity, depression, and anxiety are also contributing factors (Pazoki, Nabiour, Seyednezami, and Imami).

There are different treatment options for coronary artery disease. Two treatment clinical options include lifestyle modification and revascularization. Lifestyle…… [Read More]

Born to Be Big Childhood

People can exercise their free choice at the grocery store by choosing organic foods, although because of generally higher costs of organic products, this will not be a solution for everyone. People in lower socioeconomic groups often get food at discount chains or even food pantries where organics are not even a choice at all.

There is no incentive for makers of agricultural chemicals to modify their products in response to charges about obesogens. As the documentary films the Future of Food and King Corn pointed out, the use of pesticides is very big business. Though detrimental effects of pesticides and genetically-modified seeds and food have been shown, further research is needed to prove the link between pesticides and genetic modifications that lead to obesity in infants and children. When and if that link is proven, the public will have to demand that the government take action. Consumer advocate organizations…… [Read More]

healthy Nutrition: A Chemistry View Point

Chemistry is a branch of sciences that deals with the compositions of matter and helps in identifying the substances that form matter. Living as well as non-living bodies are formed with substances. These substances differ in their composition, nature, properties, and reactions with other substances. There is a vital role of chemicals and chemistry in everyday life of human beings. The impacts of chemical substances on living beings can also be divided into direct and indirect categories. The impact of environmental substances is indirect in nature whereas direct impacts are chemical composition of food, nutrition, vitamins, and physical activity.

The following sections are focused on detailed review of relevance for chemistry and chemicals on healthy eating habits, nutrition, and vitamins. The significant role of physical activity and exercising is also elaborated in the sections below. There are significant benefits of healthy diet and exercise.…… [Read More]

Health Blind Spot

Health and Blind Spot Enlargement in Non-Athletes

Everyone has a blind spot in the visual field caused by an absence of nerves on the retinal wall where the nerve ganglia enter. Our brains "correct" for this blind spot and fill-in the missing information so that we do not notice the blind spot in normal daily activity. As the blind spot represents a physical structure, there has been little study concerning it. There have been a few studies conducted to determine how the brain compensates for the phenomenon.

Recently, there have been studies indicating that in certain people seeking chiropractic treatment that they have unequal blind spots as a result of muscoloskeletal misalignments. This research has been controversial, however, brings up several interesting questions. There are conditions that can damage the retina and this can cause blind spots in the visual field. It is generally assumed that athletes maintain a better…… [Read More]

Role of Hormones in the Control of

role of hormones in the control of body fuel/energy mechanism has been appreciated for close to a century (Dzamko & Steinberg,2009). This concept was identified by the groundbreaking findings by the scientists, Banting et al. (1922) that the hormone, insulin could effectively restore euglycaemia. This paper seeks to give an in depth understanding of metabolism by definition and gives the various component of metabolism and finally the hormonal influence of metabolism. This paper looks into the various substrates that are influence the hormonal actions in fuel metabolism, circumstances under which they occur and the various pathways followed during these metabolisms (Becker, 2001). The intermediary compounds are also considered to the effect. In conclusion, the paper discuses the medical conditions that would arise once these hormones fail to act.

Metabolism is a biological process that takes place in living organisms throughout their lives, once metabolism stops the individuals automatically dies. A…… [Read More]

Magnetic Resonance System on Patients Magnetic Resonance

Magnetic esonance System on patients

Magnetic resonance System (Imaging), here after referred to as (MS), or nuclear magnetic resonance imaging (NMI), is a medical imaging technique widely used in radiology to visualize detailed internal structure and limited function of the body. It provides great contrast between the different soft tissues of the body, making it particularly useful in neurological (brain), musculoskeletal, cardiovascular and ontological (cancer) imaging. MS uses a powerful magnetic field to align the nuclear magnetization of (usually) hydrogen atoms in water in the body (Adams, 1989). To systematically alter the alignment of this magnetization, adio frequency (F) fields are used, enhancing the generation of a rotating magnetic field by the hydrogen nuclei that can be detected using a scanner.

MS can detect the chemical composition of diseased tissue and produce color images of brain function. This signal can be controlled by more magnetic fields to build up adequate…… [Read More]

Obesity Treatment: The Efficacy and Safety of Thyroid Hormone and Derivatives

Weight loss programs have traditionally focused on calorie intake reduction in combination with exercise, but new research suggests that it may be possible to simply accelerate metabolic rates using pharmaceutical interventions. The current drugs approved for treating obesity function by suppressing hunger or limiting nutritional absorption (reviewed by Tseng, Cypess, and Kahn, 2010). Unfortunately, the body is designed adapt to caloric availability by lowing metabolic rates during famine and to store calories as fat to guard against starvation. Drugs that suppress hunger or limit absorption activate these pathways, making long-term weight loss more difficult. The drugs that act on the satiety centers in the brain can also produce debilitating psychotropic side effects. The current state of effective pharmaceutical intervention on behalf of obese patients is therefore lacking approved drugs that increase calorie expenditure safely over…… [Read More]

Counterbalance of Sugar and Fat Content between Insulin and Glucagon

Physical survival depends on the sustained availability and use of energy in the form of adenosine triphosphate or ATP from sufficient levels of a substance, called glucose (owen, 2001). The use of energy depends on the varying levels of activity. Hence, the amount of glucose needed for activity likewise varies each day. Too much or too little glucose is damaging to the body, hence the need for some system to regulate the availability of glucose. It must be present at the precise time and amount that it is needed in order to maintain what is called glucose homeostasis. Homeostasis is the tendency of the body to maintain internal stability and balance through the coordinated responses of body parts to stimuli or conditions (owen).

Insulin and Glucagon

The regulation of glucose availability begins with the pancreas, primarily by…… [Read More]

Dehydration Water Is More Important

" (Klotter, 2001) Additionally, salt functions as an extraction agent for excess acidity in the body which are in the form of "hydrogen ions, and oxidants from ATP production" from cells. (Klotter, 2001; paraphrased) Morris (2008) states that in order for the body to become adequately hydrated the individual should replace fluid lost by perspiration when exercising and should always drink water prior to consuming food. The ideal water intake for someone who exercises is stated to be as follows: "Drink 17 ounces of water 2 hours before the activity and weigh yourself right before you exercise. While you exercise, drink 6-10 oz. every 15-20 minutes." (Morris, 2008)

(MRN, 1) This is to indicate that brain cells
are more actively produced by physical activity, convincing neurological
theorists that regular athletic orientation will improve one's academic
capacity and intellectual clarity. Still, as with other beneficial aspects
of an athlete's physical and intellectual growth, sporting activity must be
pursued in at least some degree of moderation. For both the implications
of what Metzl refers to as overuse and the consequences of an overly
centralized focus on athletic activity, there may be real and long-term
repercussions to failing to balance this emphasis with other healthy or
meaningful activities. Especially concerning bone and joint injuries,
overuse of specific parts of the body in a continuous and monotonous manner
will result in chronic pains and ultimately, lifelong localized injuries.
Therefore, especially when training for an endurance event, where sustained
energy is crucial, in training moderation can be a key to the prevention of…… [Read More]

Managing Long-Term Health Care Needs

Lee is only the first step in the process of building a team that is able to cover all aspects of Mrs. Lee's care. The team approach involving a social worker, nurse, physician, pharmacist, and physical therapist affords Mrs. Lee a full range of professionals attending to her various needs.

Although Mrs. Lee has a number of problems that need to be addressed the one problem that must be addressed immediately is her elevated blood pressure. Hypertension is an important risk factor for the development and worsening of many complications of diabetes and an elevated blood pressure is like walking around with a detonated bomb. Within moments, and with little warning, a diabetic patient can suffer a stroke or heart attack as a result of an elevated blood pressure. Well over fifty percent of diabetics suffer from hypertension and proper treatment of hypertension can minimize most of the tangential problems…… [Read More]

African-American Female Obesity

Obesity is a serious social problem in America. The effects of obesity in childhood are well documented in both the social science literature and medical journals. During the last 30 years, the percentage of obese children between the ages of 6 and 11 has risen 200% while the percentage of obese children between 12 and 19 has tripled (CDC, Preventing Childhood Obesity, 2010). Obesity in the nited States has increased among all cohorts and ethnicities, spans across generations, and is not limited to income or educational levels. However, the incidence of obesity among African-American women is of particular concern given the prevalence and severity of the issue in America.

Public health issue

More than two-thirds of Americans are now obese or overweight (Ogden et al., 2010).

Rates of adult obesity now exceed 20% in 49 states and D.C and 25% in 40 states. By way of comparison, in 1991, rates…… [Read More]

Thermo Therapy

Thermo Therapy

Application of healing thermal agents to certain body areas that feel wounded or dysfunction is heat treatment. The main use of a heat treatment is to help alleviate pain, support muscle repose, increase function of the tissue cells, improve blood flow, and remove poison from cells and to increase the extensibility of soft tissues. Superficial and deep are the two types of heat treatment. Superficial heat treatments apply heat to the exterior part of the body. Heat aimed at certain inner tissues through ultrasound or by electric current is deep heat treatment. Heat treatments are favorable before exercise, giving a limbering up result to the soft tissues involved. Heat treatment using conduction as a form of heat transfer in hot pacts is very common. Damp heat packs are easily available in most hospitals, physical treatment centers and sports teaching rooms.

For tissue heating many thermal agents are on…… [Read More]

Lift Heavy Things in the

In order to move the load, the worker should use their feet exclusively in changing direction, and walk in a steady, even stride towards the destination.

hile moving, the load should be kept as close to the body as possible. This increases the stability of the load. If the load is held out, this increases the burden of the work to the arms and lower back. This results in a dramatic increase in stress to the lumbar region. The legs and abdominal muscles bear less of the workload. It should be remembered at all times that the legs are the strong muscle group and the abdominal muscles are the best source of core stability. To reduce their role in the lift is to increase the risk of injury to other muscle groups.

hen the load has arrived at the destination, the process for set-down should be the reverse of the…… [Read More]

Bdd in Men Various Problems

"

In addition, to media images that bombard men there are also biological factors that influence the development of BDD in men.

According to an article entitled "Bigger Isn't Always Better - muscle dysmorphia in men" the most severe cases of muscle dysmorphia involve a biological predisposition for the disease (Bartlett 2001). The author explains that from a biological standpoint the man suffering with the disease has a form of obsessive-compulsive disorder (Bartlett 2001). For instance someone who washes his hands 10 times per day is normal, however washing your hands one hundred times per day to the point that it hampers with the rest of your life is a symptom of a greater problem (Bartlett 2001). According to the article this example is used to illustrate "there isn't anything pathological about going to the gym regularly or dieting," but there is a problem when "a huge number of boys…… [Read More]

Dehydration Impacts on Human Metabolism In This

dehydration impacts on human metabolism. In this sense, a short introduction in the issue of deficient water input is followed by delimitating the notions of metabolism and dehydration in terms of definition and classification. Afterwards, focus falls on the possible degrees of dehydration and body mass loss, and their implications for a human body.

According to usan Kleiner, Ph.D., "water is the one essential element to life as we know it" (Rabkin, 2000). It makes up approximately 60% of an individual's body mass. Each human cell, tissue and organ needs it in specific amounts in order to function properly, and nearly every life-sustaining body process requires it, too. Water is present in human muscles, fat cells, blood and even bones, transporting nutrients and oxygen to cells, helping to discard waste products, moistening skin tissues, mouth, eyes and nose, and most importantly, keeping body temperature in check.

Thus, water is unspeakably…… [Read More]

William Wundt and Experimental Psychology

Titchener was aware of the possible effects of bias, as well as of faulty memory, on introspection. But he believed that the problem with bias can be remedied by preparing relatively simple tasks, by exercising strict standardization, and by extensively repeating the task within and between subjects. As for the problem with faulty memory, Titchener acknowledged that introspection is the similar with retrospection.

Titchener's version of introspection is similar to Wundt's idea of self-observation. And since Wundt denied self-observation a spot in his laboratory because of its being highly susceptible to bias, he also rejected Titchener's systematic experiment introspection. Caution must be exercised to avoid taking Wundt's introspection to be a single idea, instead of it being split to internal perception and self-observation. Caveat, also, in taking Wundt's introspection and Titchener's systematic experiment introspection to be the same.

Wundt used introspection (specifically internal perception) as a primary tool in his…… [Read More]

Tissue Maturation Body System Effects

Tissue Maturation: Body System Effects

On the cellular level, the body groups similar organisms to create tissues. Such cellular tissues do not perform in isolation, but collectively, they perform a specialized function, building a larger living organism called the human body. The human body contains four types of tissues: muscular, epithelial, nervous, and connective. Accordingly, at least two different types of tissues form various organs to serve a specific purpose in the human body, such as the liver, kidneys, heart, and skin. These organs create systems that combines two or more different organs that work together to provide a common function in which ten major organ systems exist in the human body: Skeletal System, Muscular System, Circulatory System, Nervous System, Respiratory System, Digestive System, Excretory System, Endocrine System, Reproductive System, and Lymphatic/Immune System. Interestingly, the skin is the largest organ in the human body, which is comprised of all four…… [Read More]
