Sports drinks are used to rehydrate athletes during and after exercise. However, the efficiency of these electrolyte drinks has been questioned.
During respiration glucose from food is added to oxygen to form ATP,C02, and H20. During exercise, glucose and oxygen are used at a much faster rate due to increased muscle contractions. There are two types of respiration; aerobic and anaerobic. During aerobic respiration,glucose is added to oxygen to produce CO2,H20, and 38 ATP molecules. However, during high-intensity exercise,the oxygen supply is less than the demand. Because of this, anaerobic respiration takes over. This type of respiration can occur without oxygen, however ,it only produces 2 ATP molecules in comparison to 38. In addition

During exercise, glucose is required in large amounts at a faster rate. The glucose and fructose (which is converted to glucose) in sports drinks provides the cell with the carbohydrates that are required for ATP synthesis. In addition to glucose, electrolytes such as sodium are added to sports drinks. The thirst mechanism doesn't initiate until 2% of bodily fluid has been lost. However, by the time the thirst mechanism initiates,performance has already decreased. Sodium initiates the thirst mechanism prematurely to solve this problem. In addition to premature thirst initiation, sodium assists muscle …show more content…
Before exercise, the cell and its surroundings are in an isotonic state.This means that there is the same amount of water and molecules on both sides of the membrane. During exercise,water is lost at a faster rate through perspiration. Therefore, the cell goes into a hypotonic state, which means that the water rushes into the cell via osmosis; the movement of water from an area of high to low concentration. The majority of sports drinks are isotonic. Some scientists argue that the isotonic state of sports drinks renders them ineffective in regards to cellular hydration. It has been argued that because water isn't entering the cell during an isotonic state,performance is impaired due to improper cellular hydration. It should be noted that sports drink consumption after exercise is detrimental. After exercise,glucose demand slows down. When the supply of glucose from sports drinks is greater than the demand,it is eventually converted to fat via lipogenesis. In addition to the negative effects of sports drinks, it is also important to take into consideration, the fact that glucose/electrolyte requirements and sport drink ingredients will vary. Therefore,while one sports drink could improve performance for one person, it could be ineffective for someone else. Also,sport drinks are likely innefective for aerobic (cardio based) excercises that
Sports Drinks Replace Water – So many people replace water with sports drinks during exercise. The truth is, most people who drink sports drinks would be much
It is evident that healthy adults running a marathon that replaces with only free water will run into pathophysiology challenges that will affect performance. Adequate fluid intake is crucial for prolonged, strenuous exercises to maintain adequate hydration, thermoregulation, maintain plasma volume and avoid dehydration (Duvillard et al, 2004). Although athletes are prone to hydrate as much as they can during extensive marathons, research shows that fluid replacement with only free water or even hypotonic beverages can be detrimental.
This study targets the physical effect of caffeinated energy drinks on athletes, in both genders, in team sports, primarily the capacity of the participants to perform repeated sprints during a simulated match.
Have you ever gotten a sports drink instead of a soda thinking you were choosing a healthier option? Well this might change your perspective. Powerade and Gatorade are just watered down soda; yes, it gives you electrolytes which is what you lose when you sweat, but that does not mean it is good for you. There are many other healthier ways of getting electrolytes than by just drinking a sugar drink. In the Powerade article written by the company does not argue about how water is not helpful to athletes and does not have the opposing argument. Although the gatorade article written by David R. Lamb they make it more persuasive than informational.
I believe sport drinks are overhyped because it's no different than having a soda or juice because it's all extra calories.
Each sports drink contains 21 grams of sugar are contained in a 12 ounce bottle of Gatorade. With most bottles being 32 ounces, the consumer is actually ingesting 56 grams of sugar. Although this is not healthy, it is less grams of sugar than an average soda per ounce. “In fact, Berkeley researchers say the sugar in sports drinks may be contributing to the child obesity epidemic by increasing their caloric intake”. For consumers that are less active, the added sugar in their diet is not recommended. Weight gain from extra calories has also been found to be a problem for less active consumers. “For people who are not exercising for at least one hour, 5 days per week, water is the best bet for staying hydrated.” Experts suggest sports drink consumption should be monitored by children’s parents. The best source of hydration for children continues to be water (Schaefer). Unless a person is participating in vigorous exercise for a long period of time, water is the best option for
It is important for anyone doing physical activity to keep well hydrated, for performance to be at its best. Sports drinks are specially formulated to help people rehydrate during or after exercise. Drinks such as Gatorade and Powerade contain the main electrolytes and carbohydrates, which are used by the working muscles, to maintain optimal sports performance (Medindia.net, 2014). The acidity of sports drinks and the sugars, is raising health concerns, and creates unnecessary calories. (Nutritionwonderland.com, 2014) Sports drinks are proven to only be necessary when working intensely for over 90 minutes, so an athlete running a marathon may need a Powerade, but water is the best source of hydration for exercise of 90min or less.
Many arguments have risen on the matter of drinking sports drinks or water. Sports drinks are becoming more popular every year, drawing more attention to them. This is causing people to stop drinking water and begin drinking sports drinks. The question is, which is the right choice?
Sports drinks can do things that water normally can't do. Water is useful by keeping hydration. Sports drinks can do more. According to Source A, sports drinks provide electrolytes and carbohydrates. Both nutrients offer energy boosts that can give longer workouts. Second, sports drinks have bette flavor than water. According to Source B, sports drinks are more appealing to people because of flavor. The flavor of the sports drinks are enjoyed by most people. This means that people will drink more of the sports drinks to have better hydration. Finally, sports drinks have better recovery than water. According to Source C, the type of drink to use depends on how long the activity was. Sports drinks are used for longer durations because the nutirents it gives. The added nutrients also give a performance boost, so sports drinks not only give energy, it also increases how well someone does an activity.
Now, first up on the imaginary and minuscule chopping block is the electrolyte. This mysterious thing inside your body. The thing that all those sports drinks will replenish. If it’s so important, why does almost nobody know what they are? What is an electrolyte? Well, an electrolyte is the ionic form of elements, like sodium, chlorine, and magnesium. To quote Nate Morrow’s article about electrolytes, “Any fluid that conducts electricity, such as this new saltwater solution, is known as an electrolyte: the salt ions of which it’s composed of are known as electrolytes” (2013, Pg. 1). Electrolytes are, at their most simple and easy to understand form, ions that help maintain the body. There are many different electrolytes, but there are several main ones in a
choose sports drinks because of their sugar and salt content, both allow water to be more readily absorbed, and even more so when taken together. everyone can make their personal sports drinks by combining a teaspoon of salt to a quarter cup of apple juice, that tiny amount of salt will encourage the body absorb fluids but isn't sufficient to make the apple juice taste bad. Bickston suggests keeping your bottles at room temperature because a warm drink will sit better with you than a cold one.
Athletes must maintain proper hydration before, during, and after exercise. In most cases, plain water is all that is needed to refuel the body; however, serious athletes who exert themselves for over an hour need to consider replenishing their electrolytes (Science Buddies Staff 2). Even professionals agree that your body needs these electrolytes to stay energized and healthy (Miller et al.). The question is which drinks contain the most electrolytes needed to replenish your body during a demanding workout?
People around the world use sports drinks and water to refuel after a workout, but that's not always a good thing. What most people don’t know is that you shouldn’t drink a sports drink after a short work, you should only be drinking sports drinks after long intense workouts because during those intense workouts you lose carbohydrates and electrolytes. Yes it’s good to drink water but a sports drink is better to drink after an intense workout to replace all the electrolytes and carbohydrates. Water may stop the thirst but it won’t fully replenish your body. The sports drink also give athletes that extra kick late in the game or race to perform at maximum level.So for workouts longer than 60 minutes grab a sports drink.
Sports drinks are used to receive energy while doing an active, or athletic, event. There are three popular types of sports drinks: isotonic (average athlete), hypotonic (low-perspiration athletes; jockeys and gymnasts), and hypertonic (long distance runners that need the extra carbohydrates and electrolytes). Isotonic sports drinks quickly replace fluids lost by sweating and supply a boost of carbohydrates. Hypotonic sports drinks quickly replace fluid lost. Hypertonic sports drinks supplement daily carbohydrate
