Brief Summary:
The stretching is performed within sports to improve muscle performance and prevent muscle injury. However, recent studies are contradictory with common practice. Then raised the possibility that stretching before physical activity performed can decrease the muscle performance of healthy subjects.

Condition or disease Intervention/treatment Phase
Muscle Strength Other: Stretching Phase 4

Study Type : Interventional  (Clinical Trial)
Estimated Enrollment : 15 participants
Allocation: Randomized
Masking: Single (Outcomes Assessor)
Primary Purpose: Prevention
Official Title: Influence of Stretching Hamstring and Quadriceps Femoral Muscles on Peak Torque and the Maximum Power of the Knee

Intervention Details:
    Other: Stretching
    Participants were divided into 3 groups. The group was referred to stretching 3 weekly for 4 consecutive weeks. Group B went 4 weeks without any intervention and held only one stretch before the re-test. And the group C performed passive knee mobilization. All participants were assessed for goniometry of the knee in flexion and extension and peak torque and power on the isokinetic dynamometer.
    Other Names:
    • peak of torque
    • performance
    • isokinetic dynamometer
