Abstract

Lower extremity strength training is one of the skills performed by physical therapists. The purpose of this experiment was to measure the percent of recovery of the quadriceps muscles after specified interset rest period lengths to obtain the optimal interset rest period length between sets in strength training.

Twelve male and twelve female healthy subjects were divided into three equal groups of eight (four males, four females). The subjects performed two sets of six repetitions of unilateral isokinetic knee extension with their dominant lower extremity on the Chattanooga KIN-COM Dynamometer. One, two, or three minute interset rest period lengths were used between sets, depending on group assignment.

Percent of recovery was obtained by dividing the peak torque of trial 2 by the peak torque of trial 1. Results, analyzed using a one-way ANOV A, showed no significant differences among the three groups of interset rest period lengths. Results also showed no significant differences in the percent of recovery between gender in the three groups. Therefore, this study concludes that interset rest period lengths of 1 minute are adequate for recovery of the quadriceps muscles in strength training for both males and females.
