Positive and Negative Effects Athletic Performance and Caffeine

Positive and Negative Effects of Caffeine on Athletic Performance
Introduction
Caffeine is an alkaloid as well as a natural intoxicant that is prevalent in coffee, tea, as well as cacao. In the contemporary setting, caffeine is the most extensively consumed psychoactive drug across the globe, enabling an individual to continue being attentive and precluding the onset of fatigue. In recent times, caffeine has become the prevalent supplement for numerous athletes. As a result of its positive impacts on exercise performance, a number of athletic organizations such as the National Collegiate Athletic Association have even began to proscribe caffeine in high doses. According to Mishra (2018), the United States Olympic Committee has reported that there are numerous positive impacts of caffeine use for athletes. These comprise of increased endurance during workout performance, team sports, as well as for short duration sports. In contrast, there are parties that believe caffeine has a dehydrating impact based on the fact that it is a diuretic and therefore causes water shortage.This essay purposes to comprehensively examine the positive and negative effects of caffeine on athletic performance.
Positive Effects
A number of endurance athletes utilize caffeine in order to enhance their performance. The justification for caffeine use is centered on the fact that caffeine enhances the utilization of free fatty acids in the course of endurance workout and as a result supposedly diminishes usage of glycogen by muscles. During athletic events that necessitate lengthy endurance, marathoners and triathletes experience decreased levels of glycogen, which are linked to exhaustion and adversely impact performance (Dunford and Doyle, 2011).
To have sufficient energy for muscles, the human body utilizes glycogen. When the amounts of glycogen stored within the body are washed-out, this results in exhaustion and fatigue. One more energy-source for the body is the amount of fat stored. Caffeine consumption is beneficial in enabling body muscles to utilize fat as the source of energy. This is advantageous to an athlete’s body based on the fact that the human body contains a lot more amount of fat stored as compared to the amounts of glycogen that are freely available for use. Therefore, when caffeine is consumed, the athlete’s body is motioned to utilize fat, and consequently this suspends the exhaustion of muscle glycogen. This is significantly beneficial to athletic performance as it can is in sustenance of energy levels (Patton, 2016).
McDaniel et al. (2010) indicate that for numerous years, several athletes consumed coffee before competitive events. However, it was not until recently that caffeine was established to facilitate the performance of an athlete. Results of studies conducted in a five year span significantly demonstrated that caffeine efficaciously increases the performances of an athlete during endurance events. More specifically, different athletes varying from marathon runners to those partaking in power and strength competitive events substantially benefit from the consumption of caffeine. For instance, a study conducted by Jenkinson and Harbert (2008) demonstrated that athletes were able to finish a cycling competition in a substantially faster period subsequent to the ingestion of caffeine. In addition, athletes in a rowing competition has their performance time cut down by 1.2 percent subsequent to consuming caffeine.
The significant ergogenic advantage of using caffeine might be more extensively linked to its role as a stimulant to a human’s central nervous system. Specifically, the role of caffeine in augmenting the endurance of an athlete’s performance is linked with an intensified sense of awareness and a diminished perception of effort. Moreover, individuals without the habit of using caffeine regularly experiences these benefits of using caffeine more enthusiastically (Dunford and Doyle, 2011). Caffeine use to enhance the performance of an employee is not just confined to the aspect of endurance, bearing on the fact that the stimulatory effects of caffeine might also improve the athlete’s strength performance. Notably, a number of strength athletes make use of caffeine to stimulate muscle fibers. The substance can also have an effect on employment of muscle for exercise by diminishing the motor unit recruitment onset and enhancing nerve transmission speed (Dunford and Doyle, 2011).
In addition to limiting basic reaction time, it is imperative to note that caffeine does not seem to aid in the performance of more intricate motor tasks, and it may even be to some extent disruptive to the body. Reliant on how much caffeine that a person consumes, the substance can provisionally increase the heartbeat rate and also augment secretion of acid in the stomach walls and also production of urine. These sorts of effects are insignificant amongst healthy adults who consume reasonable amounts of caffeine, for instance, about two to three cups on a daily basis. One of the most severe effects of caffeine consumption comprises of trembling, anxiety, sleeplessness, muscle tension, bad temper, headaches, and confusion. Typically, these effects normally take place solely in individuals who do not consume caffeine. A person’s reaction to caffeine use is dependent not just on the habituation and level of sensitivity to the substance, but also reliant on the amount of caffeine consumed, the body weight and physical condition, and also nervousness level as a whole (Letter, 1995).
Caffeine is a potent ergogenic relief that may be advantageous in both training and athletic performance. It can wield its impacts on both the central nervous system and also the outer body tissues, giving rise to different physical effects that might enhance performance. Specifically, research has demonstrated that caffeine facilitates an increase in an athlete’s level of power and speed. It also permits an athlete to partake in training for lengthier periods. Notably, caffeine consumption results in brain stimulation, which adds to unblemished thinking and increased concentration levels. Furthermore, research studies have demonstrated that caffeine does not have a direct effect on the enhancement of the maximum oxygen capacity levels, but rather aids in the process of fighting and repelling fatigue (McDaniel et al., 2010).
Caffeine consumption facilitates strength and endurance for athletes. It also facilitates greater physical performance, especially in sporting activities that necessitate the athlete to have a lot of power. On top of heightened strength performance influence, renowned to be accessible in the short run, it has also been established that caffeine aids in the mobilization of bodily fat stores. Moreover, caffeine is beneficial to an athlete in regard to speeding up the recovery process of the individual and therefore guaranteeing readiness. In addition, the caffeine in drinks enables the athlete to become progressively more alert and therefore this guarantees increased concentration and focus during the competition and therefore improves performance levels (Dunford and Doyle, 2011).
Negative Effects
One of the perceptible and prevalent effects of caffeine consumption on athletes is addiction. On several occasions, it has been perceptible that athletes become exceedingly dependent on the stimulating impact of caffeine on the body to the extent that they can no longer function without it. Mostly, recurrent and disproportionate consumption of energy drinks with a massive proportion of caffeine constituent could instigate a slight level of an addictive practice for different athletes. Studies have demonstrated that recurrent consumption of caffeine triggers particular brain chemicals that subsequently react in the same way that cocaine becomes addictive to users. This chemical reaction creates a kind of dependency, which even though is not damaging akin to other major substances such as cocaine and heroin, still poses a threat to the athlete’s performance (Anthony, 2019).
Undoubtedly, athletes are routine consumers are largely caffeinated beverages with the purposes of fighting off fatigue and also enhancing performance levels, owing to the impact of caffeine on body muscles. Research indicates that energy drinks containing caffeine have a prospective arrhythmogenic effect, which could be detrimental to the performance of athletes owing to the significantly high adrenergic activity that is established in the course of extreme workouts. For instance, research studies have demonstrated advancement of atrial fibrillation in youthful study participants after subsequent to severe ingestion of energy drinks combined with alcohol in the course of leisure activities. It is considered that that the collective consequence of extremely high amount of caffeine and other stimulating substances contained within energy drinks can instigate the inception of arrhythmias. Caffeine, in actual fact, arouses both the central and the peripheral nervous systems impacting the cardiovascular and respiratory systems. Owing to this intoxicant effect, there is worry that caffeine might escalate arrhythmic risk (Mattioli, Sisca, and Farinetti, 2019).
Caffeine also negatively impacts the performance of athletes in terms of fatigue levels, dizziness and also breakdown of muscles. In regard to athletic performance, more often than not, caffeine facilitates a stimulating impact and boosts energy levels in order for the body to function for longer. However, in the long-term, excessive consumption can result in fatigue. In addition, it creates a particular level of faintness, particularly when it ultimately starts to wear off from the athlete. This wooziness feeling is associated with the reaction processes, and it takes place in instances where the main objective of the athlete during consumption is to remain attentive for an excessive time period. Caffeine also adversely impacts athletic performance based on the reasoning that excessive consumption in a short-term period could result in an unusual case of rhabdomyolysis whereby muscle fibers that have been torn and damaged gained entry into the bloodstream. Ultimately, this can hamper the performance of the athlete due to kidney failure (Anthony, 2019).
Research has indicated that if an athlete consumes more than 200 milligrams of caffeine prior to the onset of an intense workout or performance, the consequence might be a decline in the blood flow within the body to the heart. Moreover, during a workout, the flow of blood significantly increases in reaction to the exercises being undertaken. Consequently, caffeine diminishes the capacity of the body to enhance blood flow to the heart’s muscles when required. It is considered that caffeine might cause blockage of particular receptors within the blood vessels and therefore this hampers with the regular process whereby the vessels are required to undergo dilation in reaction to the strenuous activity of a workout. Ultimately, this restricts the amount of oxygen supplied to the heart (Patton, 2016).
In general, regardless of the prospective benefits, the consumption of caffeine done at significantly high levels can place an athlete at risk of excessive stimulation. The negative effects of such excessive intake comprise of poor training, lack of sleep and eventually poor performance. The side effects of withdrawal from consuming coffee in the long run comprise of headaches, tiredness, depression, temper, insomnia, heightened heart rate, increased blood pressure, and also premature cardiovascular problems. Whereas there is minimal proof to back up the diuretic impacts of caffeine adding to thirst and electrolyte disparities, caffeine used devoid of sufficient fluids can adversely influence thermal regulation in athletes training, especially in hot settings (Dunford and Doyle, 2011).
Recommendation
The consumption of coffee could have both constructive and adverse effects on athletes and their performance levels. These effects could ultimately become extreme based on a person’s body weight and status, behavioral aspects, and also the amount consumed. The substance functions as a central nervous system intoxicant, which can create a perceptible effect on attentiveness when it gets to the brain. Remaining attentive while performing is one of the fundamental advantages of caffeine for athletes. For athletes, in line with the regulations placed by the International Olympic Committee, the limit for consumption is a maximum of 12 micrograms of caffeine for every milliliter of urine. These established limit levels enable athletes to consume healthy amounts of caffeine prior to performing in a competition (Anthony, 2019).
In accordance to Patton (2016), research indicates that the most ideal amount of coffee that can be consumed and potentially enhance exercise performance is approximately 2 milligrams to 5 milligrams for every kilogram of human body weight, and to be consumed an hour prior to the workout. Basically, this can be translated into the aspect that averagely, one cup of liquid coffee comprises of 85 milligrams of caffeine. Therefore, an athlete with a bodyweight of approximately 130 pounds would necessitate coffee amounts of about 118 mg to 295 mg of caffeine to perceive any prospective benefit in their athletic performance (Patton, 2016).
The International Olympic Committee dictates a permissible maximum amount of 12 ?g of caffeine for every ml of urine. A dosage of caffeine that varies from 9 to 13 mg/kg just about one hour before an athlete’s performance will get to the maximum permissible urinary concentration for partaking in competitions and events. Caffeine ingesting and urinary concentration is reliant on aspects such as gender and body weight. As a result, ingesting 6 to 8 cups of brewed coffee that comprise of nearly 100 mg per cup would give rise to the maximum acceptable urinary concentration. In the same way, the NCAA takes into account urinary amounts subsequent to competitions that surpass 15 ?g/ml to be unlawful. In spite of the fact that the Global Agency for Anti-doping does not consider or categorize caffeine to be a proscribed substance, it has incorporated caffeine to be part of the monitoring program, which functions to institute kinds of misappropriation in athletic competition (Evolution Nutrition, 2015).
Conclusion
Caffeine is an intricate substance that is contained in numerous organic compounds and is significantly consumed by humans in different beverages such as coffee and also in snacks such as chocolate. Statistically, caffeine is the most prevalently consumed drug across the globe. The bodily effect of caffeine varies from different adenosine receptors in numerous kinds of body tissues. For the most part, caffeine is ergogenic in aerobic workouts. As established in the paper, caffeine is considered to be an ergogenic facilitators, in the sense that it enhanced endurance kinds of workouts, for instance, running, cycling, and also swimming. From an athletic standpoint, caffeine also facilitates resistance training. Caffeine is one of the most efficacious workout supplements accessible. It is also exceedingly economical and comparatively safe to use and consume. Research has demonstrated that caffeine can facilitate athletic endurance performance, high-intensity exercise, in addition to power sporting activities.
Nonetheless, it appears to be most advantageous to trained athletes. The negative effects of caffeine comprise of nervousness, agitation, sleeplessness, queasiness, gastrointestinal pain, headaches and dehydration. The endorsed dosage ranges by body weight, but is characteristically approximately 200–400 mg, consumed 30–60 minutes prior to the exercise.
