Upper-body and lower-body strength and endurance for the PCC (n = 12) and SIZE (n = 12) groups.* denotes a significant increase at Day 43. Resistance training increased lower-body strength (p = 0.029) and endurance (p = 0.027) for both groups; however, there was no difference associated with supplementation (p > 0.05).
