Hydration is an important aspect that can contribute positively or negatively to an athlete’s performance. When an athlete becomes dehydrated, both mental and physical performance is affected, especially when heat is an environmental factor. This is a problem when high intensity exercise is involved in the training and participation of a sport. Coaches should be aware that athletes need to hydrate before, during, and after exercise in order to maintain optimal performance levels. There are different ways to maintain hydration.
Volpe, Poule, and Bland (2009), define dehydration as a “dynamic loss of body water or the transition from euhydration to hypohydration.” (p. 625) Athletic and physical education organizations often overlook the importance of proper hydration before, during, and after exercising. This is due to the lack of proper education about what is suitable hydration for sports practice sessions and competitive sessions/games. Although efforts are being made to educate athletes about the harmfulness of dehydration, some of the players still do not use proper hydration practices before, during, and after practice and competitions. (Volpe, Poule & Bland, 2009) Dehydration is an issue that coaches and athletes deal with on a daily basis. Dehydration occurs when the loss of body fluids, especially water, surpasses the amount of fluid intake. Dehydration begins as soon as the athlete starts to exercise, and if hydration is not implemented into a daily routine then performance levels may decrease just minutes into a vigorous workout. Hydration should be implemented before, during, and after exercise in order to decrease the amount of water and salt deficiencies that are associated with vigorous exercise. Also, hydration afte...

The physical demands of tournament tennis players can be and usually are very grueling. The body is using both anaerobic and aerobic metabolism along with anaerobic and aerobic muscle fiber types. Tennis is a high intensity sport requiring hundreds of short bursts of activity. Most points only last around 10 seconds(anaerobic) but there is only 25 seconds of rest in between points and 90 seconds of rest in between games which requires the player to have endurance(aerobic). Tennis matches can be long and drawn out, lasting hours or they can be fast, intense and only last an hour. This means having adequate nutrition along with an efficient metabolism is key to being able to compete at the highest level.

The extra heat produced during metabolic exchange, raises the body temperature again affecting the enzymes and heat is then removed by sweating. If the body isn’t kept hydrated during exercise, dehydration will occur, causing the blood to become concentrated. When the blood becomes concentrated, the cells no longer have enough water to function.

Caffeine has many specific benefits for different types of athletes. Though much of the research on caffeine in athletics is inconclusive, there are many athletes that believe the substance can enhance their physical as well as mental performance. It is supposed that caffeine can improve the athlete’s endurance in sports where long-term stamina is needed. These sports include cycling, running, and even soccer. In an experiment to study the effects of caffeine as an ergogenic aid, 6 regular caffeine users were monitored while they exercised until exhaustion. During this double ...
From 1980 to 2009, 58 football players have died from EHI, and in the summer of 2011 alone 6 players died from a mixture of EHI and lack of rehydration, EHI is a really big problem for football players because now they can only have 90 minutes a week of ful...

When the swimming becomes strenuous, breathing becomes labored and swimmers lose their rhythmic breathing pattern. As we swim a race, we begin to breathe faster in an attempt to get more oxygen to our muscles. When the body realizes that it is not being provided with enough oxygen, it begins the process of anaerobic respiration and lactic acid production. As the lactic acid is produced in the body, the majority of it begins to build up within the muscles. This causes acidity in the muscles, slows the ability to do more work and is natural defense mechanism for the body. It prevents permanent damage during exertion by slowing the key systems needed to maintain muscle contraction, and allows for a greater performance. When the body slows down, oxygen becomes available and lactate reverts back into pyruvic acid, allowing the body to begin recovering from the event. Once your body has recovered from the event, and a sufficient amount of oxygen has returned to your muscles the lactate will have been purged from your
Sport drinks make fluids available to the body and are consequently very effective in preventing dehydration. One tactic sport drinks use in order to accomplish this is by adding sodium and glucose to the drink. These ingredients stimulate fluid consumption by the body, causing the athlete to drink even more, and become rehydrated (Rehrer 45). Another way that sport drinks maintain hydration in the body is by having less than or equal to 10% Carbohydrates (CHO) and small amounts of electrolytes in the beverage. This composition makes fluids available for dilution of body fluids at similar rates, thu...
The human body needs water to maintain enough blood and other fluids to function properly. Along with the fluids, the body also needs electrolytes, which are salts normally found in blood, other fluids, and cells. Dehydration is a serious health problem but can be treated but coaches and athletes should try to prevent this the most by staying hydrated. One way to make sure your hydrated is the color of your urine: Clear or light-colored urine means you 're well hydrated, whereas a dark yellow or amber color usually signals dehydration. Coaches can help prevent their athletes from being dehydrated in humid conditions are by Requiring young athletes to drink plenty of fluids before practice and during regular beverage breaks even if they aren 't thirsty, Make sure clothing is light colored, lightweight and loose fitting, or exposes as much of the skin as possible, and Decrease or stop practices or competitions if necessary, or move them indoors or to a shady area. Reasons for dehydration that athletes should now and be able to prevent are Wearing clothing or protective gear that contributes to excessive heat retention,Rarely exercising ,Is overweight or obese, is sick or had a recent illness, especially involving diarrhea, vomiting or a fever,Is taking certain supplements or medications, such as cold medicine. Last if any athletes are expiriencing any feeling of dehydration symptoms are Dry or sticky mouth, Thirst ,Dizziness and excessive fatigue. f your child plays sports in hot weather, encourage him or her to drink plenty of fluids before, during and after practices and games. Teach your child the signs and symptoms of dehydration, as well as the importance of speaking up if they occur. Involve your child 's coach, too. Talk to the coach about adjusting the intensity of practice depending on the temperature and humidity on the field and support the coach 's decision to cancel games and practices
