The Ergogenic Effects Of Glucose And Fructose Coingestion During Prolonged Cycling, Daniel A. Baur May 2013

The Ergogenic Effects Of Glucose And Fructose Coingestion During Prolonged Cycling, Daniel A. Baur

Masters Theses

The purpose of this investigation was to examine the effects of glucose and fructose coingestion on cycling time trial performance and physiological responses to exercise. Eight trained male cyclists (age: 25 ± 6.2 yrs, height: 180.2 ± 4.3 cm, weight: 76.9 ± 9.2 kg, and VO2max: 61.9 ± 6.2 mL∙kg-1∙min-1) completed the study. Subjects ingested either an artificially-sweetened placebo (PL), a moderate-glucose beverage (MG: 1.0 g•min-1), a high-glucose beverage (HG: 1.5 g•min-1), or a glucose and fructose beverage (GF: 1.5 g•min-1; 2:1 ratio) during ~3 hrs of exercise ...


Cycling Time Trial Performance Is Not Enhanced By Either Whey Protein Or L-Alanine Intake During Prolonged Exercise, Adam B. Schroer May 2013

Cycling Time Trial Performance Is Not Enhanced By Either Whey Protein Or L-Alanine Intake During Prolonged Exercise, Adam B. Schroer

Masters Theses

Previous studies have reported that adding protein (PRO) to a carbohydrate (CHO) solution can enhance endurance performance. This ergogenic effect may be a function of additional calories from supplemental protein/amino acids, but this thesis has not been directly examined. Additionally, L-alanine (ALA) is readily oxidized when provided during exercise; the impact that this has on metabolism and prolonged endurance performance is unknown. The purpose of this investigation was to assess performance and various cardiovascular and metabolic outcomes during prolonged cycling, to independently gauge the efficacy of whey PRO hydrolysate and ALA supplementation. Eight trained male and female cyclists (age ...
