The aim of this study was to compare the influence of active warm-up with or without static stretching on torque values generated in equipment isokinetic to knee joint. It was a cross-section study, comparative, which evaluated the maximum strength of knee extensors and flexors on an isokinetic dynamometer at the speed of 60°/s. Twelve (12) military were evaluated, all sex male, with average age group of 25 years old ±2.5; in relation to a body mass and stature, the average values and standard deviation were 75 ± 7.5 Kg e 1.71 ± 0.1 m. Significant differences were observed on peak torque values of the knee extensors (p=0.034), knee flexors (p=0.028) and maximum peak torque values of knee flexors (p=0.034) between the tests preceded by warm-up with static stretching and the ones preceded by warm-up without stretching. There was no significant difference to maximum peak torque values of knee extensors (p=0.071). It can be understood that the active warm-up with static stretching before the maximum strength test on the isokinetic (60°/s) promotes an increasing on peak torque values of knee extensors and flexors as much as in the average values as in the maximum ones, in absolute terms, although the maximum peak torque of the extensors have not exhibited significant differences.

Keywords : knee extensors; knee flexors; maximum peak torque; strength test; warm-up.
