We previously reported (FASEB J, 29(1):LB248, 2015) that all treatment groups increased bench press repetitions after 28d of supplementation; however, total work (reps × weight lifted) during bench press was greater at 28d for CrN2X (294.6 lbs; 95% CI, 196, 393) vs. CrN (164.2 lbs; 95% CI, 25, 304) and PL (187.1 lbs; 95% CI, 37, 336, both p = 0.02). MANOVA univariate analysis of power data indicated a significant time effect with all power output variables (i.e., peak power (PP), average power (AP), and average velocity (AV)). No significant group by time effects were observed among groups. One-way ANOVA of the 3rd set of exercise performed to exhaustion revealed no significant differences among groups in changes from baseline after 28d of supplementation. However, pairwise comparison of 95% CIs revealed a significant difference in peak power and average power between CrN2X (522.8 W; 95% CI, 473.5, 572.2) and PL (422.9 W; 95% CI, 386.6, 499.1, p = 0.037) and CrN2X (470.3 W; 95% CI 422.1, 518.5) and PL (386.1 W; 95% CI, 331.1, 441.0, p = 0.025), respectively. Average power was also significantly different between CrN2X (470.3 W; 95% CI 422.1, 518.5) and CrN (384.0 W; 95% CI, 335.8, 432.2, p = 0.014). Average velocity during bench press test was also significantly different between CrN (0.629 m/s; 95% CI, 0.572, 0.686) and PL (0.525 m/s; 95%, 0.460, 0.590, p = 0.02).
