The Effects Of Sodium Bicarbonate Supplementation On Physical Performance., Tyler Walling

Kinesiology Student Research - Archive

A decrease in intramuscular pH, caused by excessive H+ production, has been known to be one of the causes of muscular fatigue during maximal exercise. The hydrogen ions are a result of anaerobic metabolism that is used to provide the muscle cell with the ATP needed during strenuous bouts of exercise. There have been a number of studies done in the area of increasing the ability of the blood to buffer these hydrogen ions as they are released into blood with lactate. Sodium Bicarbonate, or baking powder, is a strong base that is being looked at as a potential supplement …

The Placebo Effect Of The Power Balance Band On Muscle Strength, Agility, Power And Rpe., Mary Wiley

Kinesiology Student Research - Archive

Power Balance advertises that its hologram bracelet improves exercise performance by harnessing the belief in the harmony of mind and body. There is no credible scientific evidence to support these claims. Previous research has shown that any increase in performance is due to the placebo effect. The mind-set of an individual is crucial in determining whether a placebo will cause a physiological response.

The Effects Of High And Low Glycemic Index Meals On Endurance Performance., Daniel Rivas

Kinesiology Student Research - Archive

The description of carbohydrates as either simple or complex is an insufficient way of classifying them. A metabolically more informative way of describing carbohydrates is the degree to which they raise blood glucose concentrations and this is expressed in terms of glycemic index (GI). Carbohydrates which produce a large increase in blood glucose concentration, in response to a standard amount of carbohydrate (50g), are classified as having a high glycemic index. The metabolic response during exercise is different as a consequence of the glycemic indices of the carbohydrates consumed preceding the exercise, and so the choice of carbohydrate in pre-competition …

The Acute Effects Of Microhydrin On Blood Lactate During Exercise Test., Hoa Nguyen

Kinesiology Student Research - Archive

During an exercise bout, aerobic energy comes from oxidative phosphorylation. When the intensity exceeds the body’s ability to utilize oxygen, the body switches over to anaerobic sources for energy production. Adenosine Triphosphate (ATP) is now formed through the breakdown of phosphocreatine to replenish ATP and the conversion of pyruvate to lactate following the breakdown of glycogen and glucose. The lactate decreases the pH level intramuscularly causing an environment that is not optimal for exercise and leads to exhaustion and decreased performance. Microhydrin, a supplement developed to release reduced hydrogen or hydride ions (H-) into the blood stream acting as an …
