Example 3
Aerobic Exercise Recovery: Nine male, endurance-trained cyclists perform an interval workout followed by 4 hr. of recovery, and a subsequent endurance trial to exhaustion at 70% VO2 max, on three separate days.
Immediately following the first exercise bout and 2 hr. of recovery, subjects drink iso-volumic amounts of WCAP, protein and fluid replacement drink (FR), or carbohydrate replacement drink (CR), in a single-blind, randomized design. Carbohydrate content is equivalent for WCAP and CR and protein content is equivalent for WCAP and FR. Time to exhaustion (TTE), average heart rate (HR), rating of perceived exertion (RPE), and total work (WT) for the endurance exercise were compared between trials. TTE and WT are significantly greater for the WCAP group compared to the FR and CR groups. This suggests that WCAP is an effective recovery aid between two exhausting aerobic exercise bouts, and that WCAP increases exercise stamina.
