A Low Concentration Source For Improved Performance During High Intensity Exercise

To investigate the effect of food GI content on exercise induced cardiovascular, metabolic and respiratory function.

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?

As we eat protein, fat and carbohydrates, as the main energy source, carbohydrates or glucose (simple sugar) break down into complex molecules. We need steady supply of glucose in between meals and at times like doing extensive workouts, there is an elevated demand for

Do you want to get a workout in but you feel you are always short on time? Do you love running but you're not seeing the results you want?

Having taken a meal high in carbohydrates a couple of hours earlier, I embarked on my arranged exercise regimen. Right before starting the task (jogging several rounds around the field) I felt energized. After jogging for some time,

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

Nutrition is one of the most important factors in athletic performance. It provides athletes with the energy to perform their best in practice and in games. Nutrition is important in all sports, but it is especially relevant for endurance athletes who participate in sports such as running, swimming, and cycling. Regular moderate intensity physical activity has significant benefits for health. For example, it can reduce the risk of cardiovascular diseases, diabetes, colon and breast cancer, and depression (Lee, 2005).

This project involves comparing the differences between sports energy drink within the country and outside of the country. The goal of the project is determining whether 30 random sports drinks have more sugar than the other 30 sports drinks based off of location in the world. The main results of the project appeared to the examiner that when using stem and leaf plots, relative tables, histograms, boxplots, skewness, that when bringing all of this information together there’s proof of deciding which location adds more grams of sugar per serving in one bottle of a sports energy drink.

When working out what is the best beverage to help benefit your healthy lifestyle? Is water the best or is a sport drink better. Gatorade has been around for recent decades, but what real benefits does this have. Are sports drinks affective or they part of a health fad squeezing money out of you. The question at hand is if sports drinks are vital for hydration or a waste of money. Addressing the real question of what is in sports drinks that actually help improve hydration or is it just sugar packed to give a person burst of energy, but don’t really give a long term effect. This article goes more in depth to how much hydration is needed and what is the best way to receive this whether is best from water of sports drinks specifically. The initial question this article ask is, “Do I really need a sports drink? Won’t water do?”.

Many of these also contain a high level of protein, which athletes need to perform well. Protein is large molecules composed of one or more chains of amino acids (sugar) in a specific order determined by the base sequence of nucleotides in the DNA coding. Some athletes like sports drinks because the sports drink provides energy and prevents dehydration. Theses drinks are high in Carbohydrates which, are vital in keeping the high energy of your body especially when you are playing sports or exercising. During these circumstances, you need to keep your carbohydrate levels high in your system to maximize your performance. Drinking these beverages can also help adults rehydrate after an illness that causes vomiting, diarrhea, and fever.

For example; increases in 100 and 200m swimming performance (22) and increases in 2000m rowing performance (18) as well as increases in cycling capacity (17) have been demonstrated (for reviews see Refs. 10, 16). However, the precise mechanisms by which carnosine may elicit increases in exercise performance and capacity remain to be fully elucidated. During high intensity exercise, hydrogen cation (H+) accumulation is significantly increased, which results in significantly decreased intracellular pH (23). Furthermore, H+ accumulation is reported to disrupt the ability of the muscle’s contractile machinery to function (8, 12). Due to carnosine’s imidazole ring having a pKa of 6.83, it is well acknowledged that carnosine is a perfectly suited intracellular pH buffer across the entire physiological range (4). Therefore, during high intensity exercise where H+ accumulation is likely to be the biggest contributing factor that limits exercise performance, carnosine’s ability to increase intracellular buffering capacity and maintain muscular function, is suggested to be the most pertinent mechanism by which carnosine evokes an ergogenic effect (27). Hill et al., (17) suggested increased intracellular buffering capacity resulting from an increase in muscle carnosine concentrations explained a significant increase (TWD: +16.2%) in cycling capacity following 10 weeks of BA

Barre fitness classes typically start with a warm up of upper body exercises on the floor and then continues at the barre with a focus on the lower body. Barre fitness classes involve the use of weights, resistance bands, and balls. The different methods help sculpt the entire body. Some benefits of Barre workouts are the ability to burn fat quickly and define muscles. Barre workouts are popular because it can be modified for people with injuries or physical limitations.

The ketogenic diet has been trending among scientists and athletes as a method of improving physical performance and decreasing body weight. A ketogenic diet consists of high fat (>60% of energy) and low carbohydrate (<10% of energy) diet with adequate protein. This diet can induce a metabolic condition called “ketosis,” which increases levels of circulating blood ketone bodies (1). Many competitive athletes in endurance sports maintain a ketogenic diet with the concept that a low carbohydrate-high fat diet will increase the rate of free fatty acid metabolism during exercise, while preserving muscle glycogen stores for later use during the most demanding part of the exercise. One key difference between fat and glycogen metabolism is that more ATP can be generated rapidly from carbohydrate than fat oxidation. Glycogen breakdown yields 1.0-2.0 mol ATP/min while free fatty acid oxidation yields only 0.40 mol ATP/min. Several studies

As well, sport drinks have the ability to provide a subject with an increased amount of endurance for their exercise. One reason why sport drinks have this capability is due to the carbohydrates found in the beverages. These carbohydrates exist as either of two sugars, sucrose and glucose-fructose, which provide the energy for the body that makes sport drinks better to use during exercise than water (Tsintzas 155). Carbohydrate consumption allows athletes to work harder for longer periods of time and to feel better while doing the exercises. A recent study determined that runners who had only water to drink lost speed during the race compared to those who had sport drinks. Also, performance time was faster in runners who consumed the sport drinks as opposed to water. It was only during the final 17.2 kilometres of the race that the performance times began to differ and the runners who drank the sport drinks ran faster (Tsintzas 156). Furthermore, the exercise intensity was higher towards the end of the race from those runners who had the sport drinks. As with most performance enhancing implements, sport drinks have potential drawbacks.
