Abstract
The purpose of this study was to determine the effects of 2 and 5 days of Cr loading on anaerobic working capacity (AWC) using the critical power (CP) test in women. Ten physically active women randomly received 2 treatments separated by a 5 week washout period: (A) 18 g dextrose as placebo (PL) or (B) 5.0 g Cr + 18 g dextrose taken 4 times per day for 5 days. Following a familiarization trial, each subject completed the CP test at baseline and following 2 and 5 days of supplementation. The PL resulted in no significant changes in AWC following supplementation; however, Cr increased AWC by 22.1% after 5 days of loading (p < 0.05). There was a significant main effect for body weight (BW), however, there was no significant increase in BW due to Cr supplementation. These results suggest that Cr supplementation is effective for increasing AWC in women following 5 days of loading without an associated increase in BW. Verf.-Referat
