What is it about?

The aim of this study was to examine the long-term effects of static stretching of the plantar-flexor muscles on eccentric and concentric torque and ankle dorsiflexion range of motion in healthy subjects.

Why is it important?

This study was the first study to examine the effects of static stretch on muscle flexibility and eccentric and concentric torque and compared these effects in trained and untrained subjects.


Static stretch training leads to increased muscle force concentrically and eccentrically which differs from its acute effect when applied just before athletic activities, which produce a reduction of muscle strength and power. So, it is advisable to apply static stretching as a part of regular training rather than performing it just before the physical activities which will produce an adverse impact on subjects performance.
