Brief Summary

The purpose of this study is to investigate the effects of a 5-week dynamic stretching exercise training on muscle-tendon unit of gastrocnemius muscle.

Detailed Description

Muscle stretching is a common practice applied in warm-up process to enhance performance in sports and to prevent or decrease the risk of sports injury. Muscle stretching is also used for therapeutic purposes in many clinical conditions.

It is generally performed in either static or dynamic manner. The effects of stretching depend on the type, duration and timing of stretching. However, the acute and chronic effects of a stretching can be different in the same muscle.

Recent studies suggest that static stretching has adverse effects on performance, reduces maximal muscle force and is not successful in preventing non-contact injuries, as believed so. Dynamic type is reported to improve flexibility and range of motion better. But there is still debate over which prescription provides the best results in terms of flexibility, power, performance or injury protection. And the answer to the question what happens to the viscoelastic properties of a muscle when it is stretched dynamically for some period of time has not been clearly established.

This study is planned to investigate the effect of a 5-week dynamic stretching exercise training on muscle tendon unit of gastrocnemius muscle. The effects of the training program will be assessed by ultrasound.

change in pennation angle of the gastrocnemius muscle with dynamic stretching exercise training

muscle-tendon unit lengthat the end of 5 weeks of training

change in muscle tendon unit property with dynamic exercise training of 5 week will be followed

Secondary Outcome Measures
NameTimeMethod
range of ankle dorsiflexionat the end of 5 weeks of training

change in range of ankle dorsiflexion with the training program will be assessed with a universal goniometer
