After the process of randomization and allocation held by P2, the volunteers underwent the first evaluation (AV1) under the instruction of P1. This evaluation was performed at least 48 hours before the 1st stretching session to prevent possible residual effects of isokinetic and functional testing. Other evaluations AV2, AV3 and AV4, were made immediately after the 1st (acute response) and 10th sessions (acute post elongation) and 48 hours after the last (residual chronic response), respectively, for EAG and GAD. Already the subject of gc were subject only to the four evaluation processes, where the last assessment (AV4) coincided with the time related to the stretching protocol of the experimental groups. Despite receiving the same guidelines of the other groups on the importance of stretching activities routines during the study period the volunteers were told they should not perform stretching in the day-to-day.
