The Independent And Combined Effects Of Carbohydrate And Caffeine Ingestion On Cycling Performance, Tiffany L. Acker May 2010

The Independent And Combined Effects Of Carbohydrate And Caffeine Ingestion On Cycling Performance, Tiffany L. Acker

Masters Theses, 2010-2019

Purpose: The purpose of this study was to determine the independent and combined effects of carbohydrate and caffeine ingestion on performance and physiological parameters during high-intensity aerobic cycling (~60 minutes). Methods: Ten cyclists (28 ± 3 yr, 73.2 ± 1.9 kg) performed 20 minutes of steady-state cycling (60% Wmax) followed by a simulated 20-km time trial (TT) under the following four treatment conditions: placebo (PLA), carbohydrate (CHO), caffeine (CAF), and a combination of CHO and CAF (CHO-CAF). One hour prior to exercise subjects ingested a placebo/caffeine capsule. Beverages (250 ml) were consumed immediately prior to the 20-min steady-state, immediately ...


Altered Carbohydrate And Protein Content In Sports Beverages: Influence On Recovery From Heavy Endurance Exercise, Christopher Boop May 2010

Altered Carbohydrate And Protein Content In Sports Beverages: Influence On Recovery From Heavy Endurance Exercise, Christopher Boop

Masters Theses, 2010-2019

Purpose: The purpose of this study was to compare the efficacy of different carbohydrate-protein recovery beverages following heavy endurance exercise. Methods: Twelve well-trained male cyclists completed a glycogen-depleting trial followed by a 4 hour recovery period before completing a simulated 20-km time trial. During the recovery period, subjects consumed one of three isocaloric beverages [high-carbohydrate/low-protein (HCLP); low-carbohydrate/high-protein (LCHP); carbohydrate (CHO)] at 0h and 2h, as well as immediately following the 20-km time trial. Creatine kinase (CK), muscle soreness, isometric peak torque (MVC), and mental/physical fatigue/energy ratings were measured pre- and post trial. Glucose and lactate were ...
