The Effect of Water and Glucose Solution During Moderate Intensity Exercise on Post-Exercise Apetite

The concept of energy intake and expenditure refers to the amount of calories per day that an individual consumes, and is the chemical energy in foods which can be metabolized to produce energy available to the body. As stated before energy is obtained from the foods we eat and is used to support an individual’s Basal Metabolic Rate, energy is measured in calories or joules as both units are very small they are multiplied by 1,000 and referred to as kilocalories. Different foods provide us with different amounts of energy, and the potential fuel sources available to exercising muscles are fats – 1 gram fat =9.0kcal = 23kJ,

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

M1 give examples of the impact of energy balance and hydration in relation to sports performance

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

Nutritional factors that can cause fatigue include depletion of glycogen stores, low blood-glucose levels, dehydration, low blood-sodium levels and gastrointestinal upset (Hargreaves, 2001). Eating strategies should be undertaken to avoid or reduce the impact of these problems. (Asker, 2011) states that the effect of high-CHO intake in a diet increases muscle glycogen and in-turn reduces the risk of chronic carbohydrate depletion which can lead to poor performance outcomes in a single session and sub-optimal training adaptations in the long term. Therefore, implementing a CHO loading strategy based on training and sporting requirements will assist in performance and reduce the risk of fatiguing. Fat also provides the main fuel source for long duration, low to moderate intensity exercise, such as marathons. It is also a contributor in helping access stored glycogen during high intensity exercise. Daily refuelling allows competition nutritional strategies to be practised and refined and is a crucial strategy to enhance performance and recovery during training and event

How ever there was a huge change in food intake after participants engaged in High Intensity Exercise. There was a difference shown with a significance of (P<.05). This helped the researchers come to the conclusion that High Intensity workouts are beneficial for the 24 hour energy balance. However it found that these effects usually don’t carry over into the next day. It also showed that while the consumption levels fell the types of food which they consumed did not change

The reason for this lab/research study is to know the physical effects on water vs Gatorade in exercise in a limited period of time. There are 2 subjects that are always active ,one male (19 years old) and the other female (35 years old). Both of the subjects were asked to a 90 minute workout session which included walking. During one session, the male was consisted drinking a 32 ounce fierce grape Gatorade and the female was drinking 32 ounces of water. There was a big differences in “peak rating of perceived exertion”. By the data taken it was suggested that

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,

Subjects were given their treatment of either beetroot juice or placebo ninety minutes prior to commencing the examination. Then, they began the treadmill portion of the exam, where VO2, VCO2 and RER data was collected at each varying intensity of the test. After completion of the treadmill test, subjects were then taken to an indoor track to complete the 1500m TT. This began 2.5 hours post-supplementation. After completion of the TT, subjects were then briefly quizzed to confirm the anonymity of the treatment they received. There were four experimental trials performed, with blood sampling occurring at the conclusion of each for plasma NO3 analysis. Throughout the course of the experiment, dietary standards were set in order to reduce confounding variables that would potentially alter the accuracy of the experimental procedure. Additionally, the supplementation blinding used by the experimenters was very successful, as subjects were only able to correctly identify the treatment they received 50% of the

Immediate ingestion of carbohydrate is important because insulin sensitivity causes the muscle cell membranes to be more permeable to glucose within 45 minutes post-exercise. This results in faster rates of glycogen storage and provides the body with enough

Both subjects recorded values for VE and FEO2% which allowed the absolute Vo2 (L/min) to be calculated. This was done by multiplying the VE by the difference between FIO2 and FEO2., where the FIO2 is always 20.93%. For the male participant during warm up, the calculation was .16VE x (.2093-.15) = 0.9488 (L/min) as his absolute VO2. This value was multiplied by 1000 to convert to ml and then divided by his body weight, 94.5kg, to find the relative VO2 of 10.04 (ml/kg/min).

Person X’s heart and ventilation rate was normal before the test because they had not begun exercising and were at a resting rate. The reason their heart and ventilation

Sports drinks are drinks consumed by athletes and professional sports men and woman to rehydrate and replace energy. Sports drinks contain varying levels of fluid, electrolytes and carbohydrate which all play a role in rehydrating and replenishing the body after strenuous physical activity. There are three types of sports drinks on the market; isotonic, hypotonic and hypertonic. Isotonic drinks provide the athlete with fast fluid replacement which was lost by sweat, these drinks provide a boost of carbohydrate, this type of drink is the most preferred by athletes as these contain glucose which is the body’s preferred source of energy. Hypotonic drinks are the same as isotonic but don’t contain the carbohydrates this is ideal for athletes who want fast hydration but don’t need the energy boost. Hypertonic sports drinks are said after exercise to top up muscle glycogen stores using carbohydrates. The thing that all these different types of sports drinks have In common is that they are designed to improve or maintain athletic performance, and prolong dehydration. The isotonic and hypotonic drinks both contain electrolytes potassium and sodium; electrolytes are very important in the body with many functions.

The subjects refrained from caffeine, standardized diet, and standardized training for 48 hrs before the trials. For 24 hours before the trials, each subject was given a prepackaged standard diet. Exercise and food diaries were kept and checked for compliance.
