In the current study, we examined the relationship between serum creatine kinase (CK) activity following upper body resistance exercise with a 1- or 3-min rest between sets. Twenty men performed two sessions, each consisting of four sets with a 10-repetition maximum load. The results demonstrated significantly greater volume for the 3-min condition (M = 4,156 kg, SD = 867, for 3 min; vs. M = 3,503 kg, SD = 759, for 1 min; p less than 0.001), with no significant differences in delta CK activity between conditions (p = 0.574). Nevertheless, there was a weak correlation between the delta CK activity and total volume of exercise completed (r = 0.55 with a 1-min rest, and r =0.45 with a 3-min rest). Therefore, the volume following upper body resistance exercise correlates weakly with serum CK levels, irrespective of rest interval length between sets. (Contains 2 tables and 2 figures.)
