Mouth Rinsing With Branched-Chain Amino Acids And Carbohydrates On Steady-State Metabolism, Exercise Performance, And The Endocrine Responses To Exercise, Zebblin Matthew Sullivan Jan 2011

Mouth Rinsing With Branched-Chain Amino Acids And Carbohydrates On Steady-State Metabolism, Exercise Performance, And The Endocrine Responses To Exercise, Zebblin Matthew Sullivan

Graduate Theses and Dissertations

Previous research suggests that mouth rinsing carbohydrates (CHO) improves exercise performance. The mechanisms for the improvement are not yet known, but may involve maintenance of insulin concentrations during exercise or attenuation of centrally-mediated fatigue from putative, caloric-responsive receptors in the oral cavity. The purpose of this study was to determine the effects of mouth rinsing branched-chain amino acids (BCAA) or CHO on cycle time trial performance, blood markers of central fatigue (prolactin), plasma insulin, glucose, and lactate concentrations, substrate oxidation during steady-state exercise, and the subjective exercise experience. Ten healthy, endurance-trained adult males (23.5 y 3.8 y, 74 ...


The Use Of Ki To "Psych-Up" And Increase Strength, Mark Adam Tschampl Jan 2009

The Use Of Ki To "Psych-Up" And Increase Strength, Mark Adam Tschampl

Graduate Theses and Dissertations

In many modern sports where an explosion of power/strength is necessary, such as weight lifting, shot put, and tennis, athletes often yell or grunt to "psych-up" and improve performance. Martial artists have been using a similar technique for centuries called a "kiap". Unfortunately, there is little scientific evidence that yelling or kiaping improves performance. Therefore, this study examined the effect of kiaping on strength during a handgrip exercise in novices and experts. Fifty participants (25 novice and 25 expert martial artists) completed a handgrip strength test under three conditions, a baseline test, a no kiap control condition, and a ...


The Effect Of Sodium And Carbohydrate In A Rehydration Food On Subsequent Exercise Performance, Huimin Yan Jan 2008

The Effect Of Sodium And Carbohydrate In A Rehydration Food On Subsequent Exercise Performance, Huimin Yan

Graduate Theses and Dissertations

The purpose of this study was to determine the effectiveness of two rehydration beverages on fluid restoration and metabolism on subsequent exercise following exercise- and heat-induced dehydration. Twelve male subjects were dehydrated by ~3 % of body mass with exercise and heat exposure. In a randomly assigned, counterbalanced design, subjects were rehydrated at room temperature with either 175 ml of chicken noodle soup (SOUP: Campbell Soup Company, Camden, NJ) or an artificially sweetened placebo (CON) at the beginning of the 120 min rehydration period and 20 min later. Water was ingested every 20 min during the remaining 100 min of rehydration ...
