Analysis Of The Level Of Dehydration In Sports

Task 2 – Describe (P3) or explain (M1) the concept of energy intake and expenditure in sports performance.

When athletes are training or competing, it is apparent that they sometimes benefit by consuming various drinks that contain water, carbohydrate and electrolytes. This can assist and improve an athlete's performance, and it may reduce physiological stress on an athlete’s cardiovascular, central nervous and muscular systems. During endurance events Gatorade is an effective drink to have in order for the athlete to sustain their maximum energy throughout the competition. Gatorade has been proven to reduce the risk of hyponatraemia, improve endurance performance if consumed during training or competition and it allows fast release of fluid to the tissue as well as rapid fluid absorption.

Gymnastics is one of the most demanding and dangerous collegiate sports. Marina and Rodriguez (2014) investigated the physiological demands of women’s competitive gymnastics routines. Post-exercise heart rate, oxygen uptake, and peak blood lactate concentration were studied from eight elite female gymnasts. The gymnasts reached their highest heart rates (183-199 beats/minute), their highest oxygen uptake (33-44 mL/kg), and their highest blood lactate levels (7-9 mmol) following the floor and the uneven bars. The mean oxygen uptake levels of the gymnasts for all four events ranged from 65 to 85% of their individually recorded VO2 maximums and their maximum heart rates. Gymnasts work at very high physical levels during practice and competition.

Overall, all the participants did not meet recommendations for CHO, Vitamin A, D, C, B1, and B6 during training and, in addition, women did not consume the recommendations for PRO, calcium, iron, and zinc.5 Furthermore, during the race 75% of the runners doing the 60- km race fell short on getting the recommend CHO. For the 120-km runners, 3 of the 4 men took in greater than 500 ml/h of fluid, which met recommendations, but only 1 runner took in greater than the recommended CHO during the race (108 g/hr). One major limitation of this study is that the four runners PRO, sodium, and fat intakes weren’t recorded during the 120-km

This article is about the typical time when sports scientists have been struggling with the employing the training load. It is generally recognized that well organized training program is important for best performance in athletes. Now days, it has been very hard to measure the training loads in athlete teams due to the difficulty in determining the numerous types of pressure faced during training and competition.

Danielson et al. (2006), aimed to investigate the physiological effects of water vs. Gatorade after a prolonged period of intense exercise. The predictor variable in this study was water or Gatorade consumption by each of the participants (Danielson et al., 2006). The response variable was the physiological effects during and after the performance (Danielson et al., 2006). As stated on their website Gatorade.com, increasing fatigue and fluid losses can impact performance negatively. In this study Danielson et al. (2006), defined performance as extended treadmill exercise

In addition to staying adequately fueled, hydration also plays a critical role in performance. Proper hydration can help you think clearly, improve mental focus, increase productivity, reduce stress, and regulate appetite. Include fluids with each snack to help maintain hydration. Choose water or try an unsweetened tea.

Using 15 articles increases the reliability and diverseness of the information presented. Another strength of this review is that it includes a good mix of studies which included a 10-year longitudinal study, case controls, and comparisons. Weaknesses of this systematic review include: limiting articles to those that are in English, the inclusion and exclusion criteria selected, and limiting the search within three databases. These limitations could have resulted in the analysts missing key information from other sources, that could have offered stronger support or contradiction. Other weaknesses include the size of the studies conducted, and the selection criteria of healthy experienced athletes for many of the studies, as this may not accurately represent the larger

The three main components that contribute to an athletes health are excerise, nutrition, and recovery. Exercise is important because it builds lean muscle and reduces the risk of injury. Nutrients helps rebuild the muscle after exercise. Recovery after every workout is necessary to repair the muscles. It is an athletes' responsibility to maintain a healthy lifestyle in order to succeed on and off the field.

The first task is water. You always fill up the water and get it where it needs to be. If the boys or girls don’t have water, they will dehydrate. The sports trainers don’t need the boys or girls to dehydrate because that will and can lead to getting cramps. If the boys or the girls get a cramp they have to eat or drink mustard, pickles, or pickle juice.

Not only is muscle fatigue and muscle recovery affected there are many other physiological factors that are affected as well. These physiological factors play a major role in athletic training and must be maintained if athletic performance is expected to stay at a high level. A few of these factors are VO2 max, maximal heart rate, stroke volume, economy of movement, and aerobic enzyme activity. (Reaburn) Many of these elements play a smaller role in accounting for and culminating to another one. An example of this would be how stroke volume, muscle mass, and aerobic enzyme activity play a major role in the process of VO2 max. When you observe a decrease in all of these things you will see that there will be a major decrease in the athlete’s

Athletes were asked to place a check mark by the topics that they would like to learn more about. The percentage of athletes selecting each topic is in Table 3. The tests detected significant differences for the topics from weight control, weight gain, and cooking demonstrations. Only 31.2% of the athletes selected “weight gain” as a topic that
