Brief summary

Stretching effects skeletal muscle flexibility, vascularity and physical performance. The aim of our study is to examine the acute effects of static stretching duration on gastrocnemius muscle vascularization in healthy participants by superb microvascular imaging (SMI) and to compare the effects of 2 and 5 minutes of static stretching on blood flow.

Detailed description

The study will be included 30 healthy volunteers. The participants will be divided into two groups. Static stretching was administered to the gastrocnemius muscle. Stretching applications will be applied to the first group for 2 minutes and to the second group for 5 minutes. Muscle vascularization will be evaluated by a new method, superb microvascular imaging (SMI). SMI is a recently developed ultrasound imaging technique that aims to visualize low velocity and small diameter blood vessel flow.

Interventions

BEHAVIORAL2 Minute Static Stretching

Stretching applications will be applied to the first group for 2 minutes. Static stretching exercise will be performed under the supervision of a physiotherapist as 30 seconds of stretching and 30 seconds of rest and and the individuals will be asked to participate in the exercise actively.

BEHAVIORAL5 Minute Static Stretching

Stretching applications will be applied to the first group for 5 minutes. Static stretching exercise will be performed under the supervision of a physiotherapist as 30 seconds of stretching and 30 seconds of rest and and the individuals will be asked to participate in the exercise actively.
