Exercise Physiology
1. What factors should be considered to provide maximal protection when people are exercising in the cold?
Conducting exercises and partaking in competitions in the cold weather circumstances is usually less risky in comparison to circumstances of extreme heat. Nonetheless, there are different factors that have to be taken into consideration in order to provide maximal protection. One of the factors encompasses staying hydrated regardless of the cold weather conditions. A second factor encompasses the clothing worn and the layers of clothing used. More often than not, people wear a lot of clothes to prevent themselves from being cold. However, while exercising it is necessary to have lesser number of layers of clothing as this can even cause an individual to faint. Lastly, there is the factor that is metabolic heat production from the body to attain thermal balance. There is a likelihood of variance in metabolic heat production owing to muscular activity. In actual fact, human beings are solely 25 percent efficient, having 75 percent of the chemical energy formed throughout muscular tightening being lost as heat. This is essential for the reason that all through continued forceful exercise heat production can surpass 20 calories every minute (Powers, 2014).
2. How would training at medium altitude and then competing at altitude affect a runners performance? How would training at sea level affect a runners performance?
Training at medium level has a significant advantage in comparison to training at sea level. This is for the reason that in such areas there is decreased air pressure and decreased amount of oxygen as well. Notably, the body requires red blood cells to transport...…do we see between spaceflight and detraining? Why does the body make these adaptations during spaceflight?
There are similarities perceived between detraining and spaceflight. One of the key aspects seen is the decrease in the thickness of the walls of the heart while pumping owing to the lack of the weight being placed on it. Basically, while on a spaceflight, the heart is not required to work as hard as normal owing to the lack of gravity at the time. This is akin to detraining because the heart ceases working with more effort as normal and becomes thinner due to the detraction of the walls. This is for the reason that the heart is also a muscle and therefore similar to other muscles, it will shrink when it ceases to work out as normal (Adams et al.,…

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
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
Muscle fiber type and performance The body majorly has two types of muscles, the slow-twitch and fast-twitch muscle fibers. Most people have, on estimation, 50% slow-twitch fibers and 50% fast-twitch ones. This however can significantly change depending on the type of training an athlete goes through. The slow-twitch muscles come into play for the endurance athletes hence they will develop more of this type over time with training. Fast-twitch muscle fibers
Heart rates in children may reach 220 or even 225 before puberty, but tend to fall to around 200 in their late teens, so the coach should not worry on finding such high rates in exercising youngsters." (Sharp, 1) This is a demonstration of the distinct physical response of the youth's body, justifying a framing of youth physical activity as separate, different and demanding its own specific scientific attention.

1. What are the similarities between Billy’s and Harry’s experiences of injury? (100 words/5 marks) There are perceptible similarities between the experiences of injury faced by both Harry and Billy. Both of these athletes find it hard to come to terms with the injury sustained. Billy and Harry are unable to cope with the fact that this injury will negatively impact their competitive careers and aspirations. Both of these individuals have
