OBJECTIVE: To examine the effect of two rest interval (RI) on isokinetic Peak Torque (PT) produced by young women. METHODS: 17 untrained women (27.18 ± 4.05 yrs; 56.84 ± 6.93 kg) performed three sets of 10 unilateral isokinetic knee extension repetitions at 60° and 180°/s with one and two minutes of RI. Statistical evaluation was performed using a two x three ANOVA [RI (one and two minutes) x set (1st, 2nd, 3rd)] with α < 0.05. RESULTS: One minute was not enough to keep PT between sets (p<0.05) at 60º and 180º/s. Two minutes was enough only at 180º/s. However, two minutes of RI was greater (p<0.05) than one minutes at 60°/s for PT during the 2nd and 3rd sets. CONCLUSION: Two minutes is sufficient to keep PT within typical isokinetic resistance training protocols at 180º/s, but not at 60º/s in young women.Downloads
