It has long been established that both short and long-term exercise increase metabolic rate and heat production. This naturally predisposes participants to dehydration. Typical symptoms of dehydration include elevated temperature, fluid and electrolyte imbalance due to sweating, and loss of critical nutrients, such as glycogen (depleted via metabolic pathways). Many individuals participating in moderate to rigorous training schedules may engage in daily exercise, if not multiple exercise routines in one day (3,4,5,6). It then follows that the goal for these individuals should be avoidance of dehydration and maximization of rehydration through maintenance of electrolyte balance, replenishment of muscle glycogen, and plasma osmolality. Thus, examination of a fluid’s efficacy in these three areas is crucial. Through extensive research, it is evident that Gatorade will rehydrate faster and more effectively than water.
Vital to maintenance of homeostasis is the regulation of plasma osmolality. The Renin-Angiotensin-Aldosterone system, which works to regulate blood pressure, plays a crucial role in fluid balance. When dehydration occurs, blood osmolality increases, which stimulates the release of antidiuretic hormone (ADH), ultimately leading to increased water reabsorption. This leads to more concentrated urine, and less concentrated plasma. Low plasma osmolality works in the opposite fashion: ADH release is inhibited, water reabsorption decreases, and urine is less concentrated. The added electrolytes and carbohydrates in Gatorade would facilitate greater fluid retention through stimulation of renin and vasopressin, increasing urinary sodium reabsorption (3). Studies of both urine volume and plasma volume changes are eff...

...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.
The sports drink group displayed the highest average specific gravity. Sports drinks have composed of a large amounts of solutes such as sugar and electrolytes which increase plasma osmolarity. In response, the posterior pituitary will release ADH which will add aquaporins to the distal tubule and collecting duct, thereby increasing water reabsorption. This will create a higher solute concentration in urine as well as a higher ...
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.

To find the answer we performed an experiment. We decided to put the drinks to the test by exercising, and then seeing how well we shoot 10 free throws. But after we exercised we drank either Powerade or Gatorade. We would then collect data, analyze it, and ultimately find out which drink is more effective. When I finished working out on Day 1, I drank Gatorade. I made 8/10. On Day 2, I drank Powerade after exercising and shot 7/10. And since the results were very similar I decided I would exercise and shoot 10 more on Day 3. But instead of drinking a sports drink I just drank water. I made 7/10. This data was very interesting. It shows Gatorade improved performance more, but nothing really stood out. So unless you plan on running a marathon or other strenuous athletic tasks, it will not really matter if you drink Powerade or Gatorade. Our experiment even showed, no matter how many fancy sports drinks come out, water is always a very reliable option when it comes to regaining lost

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.
Barnard, J. (1992) Caffeine in Sport: influence of endurance exercise on the urinary caffeine Concentration.
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.
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.
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.
Have you ever wondered if buying a gatorade before a game is worth the price or would water just be fine? I have often wondered if getting a gatorade would be worth the money or if just getting water would be fine. I play sports almost every season and always have to decide wether to get a gatorade or just drink the water they gives. I am so think that what makes the gatorade worth buying, is it just for the taste or does it have something that actually helps. I believe that learning more about electrolytes and hydration would be useful to explain which drink would be for me as an athlete during a game.
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).
Innumerous scientists confirm that nutrition and dietary supplementation can deeply affect molecular and cellular processes that occur in the body during the exercise and the recovery process. This brief review analyzes the potential for performance enhancement through protein supplementation ingestion, and the importance of nutrition education for sports supplement users.
