The intent of this investigation was to determine the minimal time for a between sets rest period during a common isokinetic knee extension strength-testing protocol. Based on a review of the literature, a set was considered a group of four maximal coupled contractions at a specific velocity.
Eleven normal, healthy college-age men underwent unilateral knee extension testing to determine their individual isokinetic peak torque at 60, 120, 180, 240, and 300 degrees.s-1. Velocities were administered in ascending order. Between sets, rest periods of 15, 60, 180, and 300 s were assigned to subjects in a counterbalanced fashion.
There were no differences in peak torque at the beginning velocity of 60 degrees.s-1 among any of the rest periods. At 120 degrees.s-1, peak torque production during the 15-s rest period trial was similar to 60 s but lower than 180 and 300 s. Peak torques at 180, 240, and 300 degrees.s-1 produced during the 15-s rest period test were significantly lower than measured torques at the same velocities during the 60, 180, and 300-s rest period tests (P < 0.05). There were no differences in peak torque production between the 60, 180, and 300-s rest period tests.
These data demonstrate that during a common isokinetic strength testing protocol a between set rest period of at least 60 s is sufficient for recovery before the next test set.
本研究旨在确定在常见的等速膝关节伸展力量测试方案中，组间休息期的最短时间。根据文献综述，一组被定义为在特定速度下进行的四次最大耦合收缩。
11名正常、健康的大学年龄男性接受单侧膝关节伸展测试，以确定他们在60、120、180、240和300度·秒⁻¹时的个体等速峰值扭矩。速度按升序进行。组间休息期，15、60、180和300秒的休息时间以平衡的方式分配给受试者。
在任何休息期之间，60度·秒⁻¹起始速度下的峰值扭矩没有差异。在120度·秒⁻¹时，15秒休息期试验中的峰值扭矩产生与60秒时相似，但低于180秒和300秒时。在15秒休息期测试中，180、240和300度·秒⁻¹时产生的峰值扭矩显著低于60、180和300秒休息期测试中相同速度下测得的扭矩（P<0.05）。60、180和300秒休息期测试之间的峰值扭矩产生没有差异。
这些数据表明，在常见的等速力量测试方案中，组间休息期至少60秒足以在下一组测试前恢复。
