HYDRATION:
One of the most important nutrients is water. The longest you would survive without water is 3 days. On a day to day basis we lose water through evaporation from our skin. This is known as core temperature. The fluid in the body helps to maintain the core body temperature. A problem that may occur is when fluid is lost and not replaced. Your body temperature will rise due to this loss and stimulate further sweating to try and release heat from the skin. Your core body temperature should be – 37 degrees
DEHYDRATION:
This is a condition caused by the loss of fluids that are not replaced. If you lose as little as 2 percent of body mass, this can cause signs of dehydration and being to affect your ability to perform muscular work.

When ingested with high volumes of water, glycerol has been proven to increase water retention. This reduces overall heat stress and hot conditions, lowering heart rate and body temperature.
HYDRATION IN SPORTS PERFORMANCE:
If you’re an athlete, you should be encouraged to begin exercise fully hydrated. Training is seen as an opportunity to practice fluid-replacement strategies that run smoothly in competitive situations.
For example, this is known as the pre-event, before a rugby match, the athlete should aim to drink approximately 300-500ml of fluid about 10-15 minutes before you start.
This is known as the inter-event, during the match the athlete is recommended to consume 150-200 ml of fluid every 15-20 minutes. If you wait until half time to replace fluid the chances are you have already started the dehydration process. This is accelerated during intense activities as the fluid takes longer to be absorbed.
After the event known as post-event. Once the match is complete it is vital to replace the fluid that has been lost. It is recommended that you should replace 1 and a half times the amount of fluid

Hypertonic drinks contain over 8% of carbohydrate and are absorbed slowly. They are ideal for fluid replenishment and may have to be consumed with other fluids. They are best used in the recovery stage after exercise.
Isotonic drinks contain the same concentration of glucose to water as the blood (4-8% glucose). They also contain sodium so that they are absorbed into the bloodstream quicker. This drink is useful when exercise has been prolonged or even during warmer weather. Isotonic drinks can also be used before exercise.
Hypotonic drinks have a lower concentration of carbohydrates than the others. They contain less than 4% of carbohydrates and are easily absorbed. These drinks encourage fluid replacement through enhanced taste.
The higher the intensity and duration of the exercise, the more important fluid replacement strategies become and the more likely that sports drinks will have a useful contribution to sports performance and recovery, by also providing energy not just fluid. Athletes will be on nutritional plans which should include fluid replenishment, this will allow the athlete to train
Hydrating is very important to your body's ability to function. Your body must intake water as we constantly let off water as said i pg 1 of ‘Strange but True: Drinking Too Much Water Can Kill’ it states “At every moment water escapes the body through sweat, urination, defecation or exhaled breath, among other routes.” As it's been told that water is good for you and needed no one has ever thought of actually being able to overdue it. When you take in water your kidney stores up to a gallon of water so as to keep you hydrated. In the article mentioned previously it also states in pg 10, “every hour a healthy kidney at rest can excrete 800 to 1,000 milliliters … therefore a person can drink up to 800 to 1,000 milliliters per hour without experiencing a net gain in water”. Therefore your body is built
In order to understand the dangers of sugary drinks and foods, an explanation of their contents is necessary. These drinks and foods are composed of high carbohydrate-content, which is responsible for energy pr...
Glycemic index is the measure of how quickly blood glucose rise after eating a particular kind of food. This is used by estimating the how much each gram of carbohydrate consumed raises a person’s glucose level. During intense exercise, the body uses glucose as energy source before it starts relying of fats. “Prolonged exercise can only be continued when there is an adequate amount of carbohydrate available to fuel muscle and the brain”(William,2004). This shows that the amount of carbohydrate/glucose that is found within the body’s tissue has a significant amount of influence to play on how effective the early hours of an exercise would be. Glycemic index helps one to know how effective the carbohydrate/glucose within the body is functioning during exercise.

Of the 258,000 athletes that wrestle in high school, only 7,408 are able to continue their career as a wrestler in college (NCAA 1). These 2.7% of wrestlers are faced with multiple adversities from making weight, to the long seven minutes of nonstop action on the mat. Although the seven minutes go buy quick when spectating, when you 're on the mat it seems never ending. A lot of work goes behind ones success on the mat. To be successful in college wrestling on must cut weight efficiently, lift weights, and warm up effectively before every match.Among college wrestlers, cutting weight is a big part of their lives. College wrestlers often believe that cutting weight will improve their chances of winning. They do this be dehydrating themselves before weigh ins, then shortly after weigh ins replenishing their fluids as fast as possible. For this technique to be effective the athletes must do it right. If not done right, the wrestler will only weaken or fatigue themselves before the competition. As the college wrestler rushes to replenish his water, electrolytes, and glycogen after weigh ins, they think by competition they will be hydrated and that their muscles will be fueled again, but it does not work that way. Replenishing body fluids takes 24-48 hours, and muscle glycogen replenishment can can up to 72 hours. Not only does cutting weight have short term effects, but has long term effects as well. This includes organ damage, eating disorders, and unhealthy eating habits.
...ble in a Gatorade bottle but these are the most important ones. The most chemistry that is present in sports drinks and in this case, Gatorade, is seen through the electrolytes. In a nutshell electrolytes are substances that are soluble in water and after being completely dissolved, they give ions. Our body consists of Cation and Anion electrolytes which are nutritionally referred to as Macrominerals. As stated before the balance level of electrolytes is every crucial for the human body, and if imbalanced the person can have serious and life threatening issues. But the only way to restore our electrolytes level is by consuming these sports drinks, so this is the main reason as for why even though the sports drinks have some negative aspects to them they are one of the cheapest and easiest ways a person can get the required electrolytes for their body.
In 2002, a group of Australian researchers published a paper entitled the "Effect of different protocols of caffeine intake on metabolism and endurance performance". Caffeine use during sporting events has become much more popular and has widely studied. The purpose of the research was to examine the work increasing (ergogenic) effects of differing regiments of caffeine on metabolism and performance while simulating the typical nutritional preparation an athlete would do for a race. The study also sought to examine the effect of timing of caffeine intake, comparing results when caffeine was given before an event (precaf) to results from caffeine given during an event (durcaf). In addition, the researchers wanted to understand the practice of endurance athletes drinking defizzed Coca-Cola towards the end of a race. It was widely observed that many triathletes and marathoners feel they derive a boost from consuming Coca-Cola in the final stages of an event as a replacement to sports drinks.
Early summer, about forty-eight years ago in 1965, University of Florida assistant football coach, Dwayne Douglas, sat down and wondered why so many of his players were suffering from heat strokes and heat related illnesses during games or practice. So, he went to the university physicians and asked them to determine why this was happening. Not long after it was discovered that two key factors were causing the Florida Gator players to suffer from these conditions: the fluids and electrolytes the players were losing during the events were not being put back into the body, and the massive amounts of carbohydrates the players' bodies used for energy were not being replenished. So, he decided to create Gatorade. There are plenty of Gurus out there who will sit and tell you that water is natural and it’s the best thing you could ever put into your body, but let’s get real I’ll take scientifically proven research over someone’s “word” any day.

Sweat excessively while exercising and you 'll lose water and electrolyte but if you drink energy drink after that just to have more energy you 'll only dehydrate yourself more.
It was expected that the participants who drank water and exercised to have their blood sugars decrease after they had started exercising but elevate after a while due to glucagon being circulated. However, blood glucose levels will not increase a lot because water does not have sugar, therefore sugar levels will not have a big increase.

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
Diuretics are substances that increase the production of urine and excretion of sodium. As a result this alters both the volume and content of body fluids(Jackson, 2006). This highly desirable quality means that the use of diuretics are abused by athletes for the benefit of both rapid water loss (to meet weight categories) and in order to mask the presence of banned substances. The competitive nature of humans means that since sporting events and competitions began, the desire to gain a competitive advantage has always been a huge factor. Nowadays in this ’commercial’ sporting world, with massive lucrative lifestyles, and the related lust for sporting success, sports men and women have resulted in countless methods to achieve a competitive edge. With an ever-growing development in medicines and chemistry, such attempts include the use of performance-enhancing drugs. This is unfortunately has become the scourge of modern sport, and their use to gain advantages in competition is on the increase. (Barroso et al., 2008).
When more water leaves the body then comes in, dehydration is occurring ("Safe Drinking Water: Tap Water, Bottled Water, & Water Filters.”). Without the water you need you can’t regulate your body temperature and your body can’t lubricate you joints ("Athletes: The Importance of Good Hydration.”). Being a dehydrated athlete won’t let you preform at your highest level ("Athletes: The Importance of Good Hydration.”). Because being hydrated helps transport nutrients to give you energy and keep your body healthy ("Athletes: The Importance of Good Hydration.”). It may cause you to experience fatigue, muscle cramps, and dizziness ("Athletes: The Importance of Good
The body looses water all day long. Water is lost through evaporation of sweat which keeps the body cool. Body also looses water in the form of sweat during exercise and vigorous physical activity. It is also lost as urine which accounts for three quarters of the body water loss. Infrequent urination or dark yellow urine indicates dehydration and means that we should consume more water.
