Fatigue in the Body
William Cotton
Exercise Physiology
Fatigue can occur anywhere in the body. Fatigue is defined as the inability of an organism, organ, or part to function normally because of prolonged exertion. It is a result of mental and physical exertion. Fatigue is something that almost everyone experiences no matter what field of work s/he may be working with. Athletes are the main focus when talking about fatigue. This is because athletes are the population that performs prolonged exertions the most. A lot must occur before fatigue sets in an individual. The central nervous system and the peripheral nervous system are the main sites of where fatigue can occur. Within these are a numerous of amounts of sites that fatigue

The CNS would be considered fatigued if there were a reduction of in motor units or a reduction in the frequency of firing. The central nervous system is the brain and the spinal cord. The CNS main function for performance is arousal and motivation. The athlete can be aroused enough or too much for performance. Both of these factors can lead to fatigue. The athlete has to be in the right state of mind- arousal- to perform. Being over aroused or under aroused can lead to decreased performance. Motivation from the CNS plays a role in performance and fatigue. How motivated the athlete is depends on how the athlete will perform. Big time games should be treated as blow out games in order to see the same results. These two can be described easily in terms of motor unit …show more content…

All athletes regardless of age, gender, genetics or sport can benefit from effective training. It is important that the selected training improves the body’s ability to perform tasks associated with the chosen
1. What body systems are primarily affected and what physiological changes would you expect Joe and Frank to experience during such rigorous exercise?
Six different subjects all between the age of 21-25 from all different physical levels performed four experiments. Each experiment consisted of two sessions a warm-up and lifting both a 10 lbs and 15 lbs dumbbell with a two-minute break between the two loads. The warm-ups were bicep stretches, which involve three different stretches and lasted for about 30 seconds each for a two-minute stretch, cardio, which included step up until max heart rate was
According to the results, the time of prior exercise and the average number of cycles after the exercise were inversely proportional. The time of prior exercise assumed to be approximately proportional to the amount of exercise. Also, the number of cycles presumed to be inversely proportional to muscle fatigue. This is because greater muscle fatigue would prevent faster rate of muscle contraction, this would result in performing a lower number of cycles during a given period. Hence, based on the graph, it was inferred that the amount of previous exercise and muscle fatigue would have a positive linear relationship. This implies that as the amount of previous exercise increased the macule fatigue increased accordingly.
As the trials progressed, the strength of the muscles decreased as well because of the experienced muscle fatigue due to the lactate threshold. In
In this assignment I will be reviewing the different effects of exercise on the body system including the acute and long term using the pre-exercise, exercise and post-exercise physiological data which I collected based on interval and continuous training method. I will also be including the advantages and disadvantages of these, also the participants’ strengths and areas where they can improve on.

Task 3 –Describe (P4), explain (M2) or analyse (D1) the importance of energy balance and their effect on sports performance.
The relationship between the principles of training and physiological adaptations has a significant impact on performance. Many factors need to be addressed in a training program to make it a successful one for a particular athlete and thus improve their performance.
The Merriam-Webster online dictionary (2015) defines fatigue as “a state of being very tired” (Merriam-Webster Dictionary, 2015). Stedman’s concise medical dictionary for the health professions (2001) further defines
Football and track and field involve repetitive bouts of quick acceleration for short and long periods, sudden changes in direction of maximum force may contribute to the high rate of hamstring strain commonly found amongst these sports. (Ropiak & Bosco, 2012). Regardless of all the aforementioned studies, there is not one exact cause of injury during high speed, kicking sports (Lees, Asai, Andersen, Nunome, & Sterzing,

Recovery is a very important aspect that many athletes don’t think about regularly. They believe as we have heard many times over that someone else is always training harder. If the proper rest and recovery is not taken advantage of, you are doing more harm than good to your body. In addition to lack of recovery comes injury. Many athletes incurred injuries do to over training because the body had not had enough time to recover and rest. We need to manage our training intensity and volume for our athletes. As the athlete recovers we hit them with a little bit more intensity and a little bit less volume. This keeps the athletes constantly showing improvement without overtraining. There is no single test for diagnosing professional burnout or overtraining syndrome. Burnout is assessed primarily through the use of questionnaires, but biochemical analyses might give important information about occupational stress and burnout mechanisms. As we move forward in the process of helping the athlete we need to look at the psychological and physiological breakdown. I feel that in order to get the athlete
“The analysis of movement provides an athlete with optimal development as well as minimising the risk of developing injuries through the incorrect execution of a movement” (Ackland, Elliott & Bloomfield, 2009, p 301).
A common adverse affect of overtraining for an elite athlete is ‘Overtraining Syndrome’. Overtraining syndrome is a neuroendocrine (neural input cells in the brain) disorder characterized by poor performance in competition, inability to maintain training loads, persistent fatigue, frequent illness, disturbed sleep and the most frequent in an elite athlete: alterations in mood state (Nature Immunology and Cell Biology Laurel T Mackinnon May 2000). Nearly all athletes experience the mood deterioration observed without impairment in sport performance. Since the goal is to reach a point of improved performance within the athlete the athlete then has to reach his/her limits of physical capacity (or even beyond) and since the balance between the right amount of training and overtraining is a fragile line many athletes suffer from this overtraining syndrome. It is not the hard training that makes you stronger in fact it makes you slightly weaker, it is the rest that will allow your body to grow stronger. Physiologic improvement in sports only occurs during the rest period following hard training. Due to this need for hardened training many elite athletes overwork themselves
