Fatigue Research Paper

1.0 Fatigue Hypothesis Fatigue can be defined as extremely tiredness resulting from mental or physical exertion or illness. Based on my first journal by van Dieen, Luger and van der Eb (2011), the purpose of the research is to test the hypothesis that fatigue due to exercise will affect the trunk stability in elite female gymnasts. The method that they used is three trials of a balancing task while sitting on a seat fixed over a hemisphere. Before the research started, all of the gymnasts were instructed to handstand on an uneven bar to make their trunk muscle fatigue. On this study, they used force plate to trace the center of pressure (CoP). For the first task, those gymnasts required to sit as still as possible on the hemisphere for 30 seconds. While the second task required the gymnasts to lean back on the seat over a set angle and suddenly released in which the subject had to regain balance. The result was recorded before and after the research. As the discussion, the writers stated that training activities will affect the trunk …show more content…

There are 71 healthy volunteers participated in the study. The experiment was divided into six phases illustrated which is familiarization session, pre-test, training session, post-test, consolidation, retention test and transfer session. The procedure of the experiment is the subject which is 15 men required to retention sleep for three hours. The authors want to observe the substances that infused or release during the retention sleep. As the result, the 3 hours of retention sleep during slow wave sleep (SWS) plays a important role in emotional memory

    With exceptional haste we begin to recite our knowledge of the human mind. As is stated in The Twenty-Four Hour Mind by Rosalind D. Cartwright, sleep allows our brain to consolidate our experiences and memories of the day (Cartwright 30) while we lay in a semi-vegetative state (Cartwright iix). The consequences of lack of sleep are evident in studies performed on individuals who suffer from insomnia. In “Sleep in the Workplace: What the Psychologist-Manager Should Know About Sleep”, the article highlights the cognitive effects that lack of sleep can have on an individual including impaired working memory, learning capability, and decision-making (Gaulltney & Collins-McNeil 135). Our rational mind dismisses Murakami’s obvious fictional short story and dismounts every claim that a human could survive without sleep.

    The data does not support the students hypothesis because it was incorrect. A possible explanation for these results is when you exercise your blood starts flowing throughout your body which causes the muscles to move faster and the amount of clothespin squeezes to increase. When a person exercises the blood flow of the person increases. When the blood flow increases, the person's level of oxygen also increases and then, when oxygen is delivered to the muscles a process called anaerobic respiration occurs. When you rest, not a large amount of oxygen is getting to your muscles which leads to the increase of lactic acid, and the lactic acid causes your muscles to fatigue.

    The particiapnts were given a five-minute rest period between each set. We provided a one- minute rest period between the squats (front and back). For five seconds the subject would maximally contract the knee extensors against manual resistance for 5 seconds, which is the same way we measured MVC. The participants would also be shaved when necessary for placement, which was something that we did not do (Gullett, J. C., Tillman, M. D., Gutierrez, G. M.,

The film starts with the statistic that “40% of American adults are sleep deprived” and followed with different effects of sleep deprivation such as: weight gain, delayed reaction time, depression, anxiety, speeds the growth of cancer, and has been linked to Alzheimer’s disease. Although, there is no scientific evidence to support the need for sleep, it is an important process that allows our bodies to function properly. Several sleep studies have been performed to understand the effects sleep deprivation has on a person. The participants of the sleep trial only received four hours of sleep per night.

    MUSCLE CONTRACTION AND FATIGUE BACKROUND INFORMATION: Muscles make up about 40 to 50 % of the male body and 30 to 40 % of the female body. In that case we can conclude that the muscles play a very important role in our body. But one of the most important things about muscles is their ability to contract and help us with movement. The first step of a muscle contraction would start with the brain. The brain sends an impulse to the muscle, which then travels down through the motor neuron to the neuromuscular junction, to which it then lets out acetylcholine.

  • Low Back Injuries: A Case Study

    Low back injuries are very common in settings where frequent lifting occurs. Lifters experience small continual mechanical and neuromuscular perturbations because moving a load provides a constant disturbance to the lifter's balance and equilibrium (Gra-ham etal. ,2011a; Oddsson etal.,1999). When you lift a weight in wrong posture, it produces the effects of compressive stress, shear stress, and bending moment on the intervertebral disc, mostly between the fourth and fifth lumbar vertebrae.
