Abstract: The purpose of this investigation was to examine the effect of IRR on kinetic and kinematic variables in the power clean during a multiple set exercise protocol. 10 male, recreational weightlifters participated in 4 testing sessions. Subjects performed 3 sets of 6 repetitions at 80% 1RM with 0 (P0), 20 (P20), or 40 seconds (P40) IRR with 3 min. rest between sets. Peak power, force, and velocity significantly decreased to a greater extent during P0, whereas were maintained during P20 and P40. In all variables, P0 was significantly different from P20 and P40. Significant differences were found in horizontal displacement (bar path) for all 3 sets of P0. No significant differences were found in horizontal displacement for all 3 sets of P20. Significant differences were found in horizontal displacement for 2 sets of P40. The addition of IRR periods may allow for a greater volume of training while reinforcing proper movement mechanics.
