Gender Differences in the Tolerance to Stretch

The Effect of Stretching on Pain Sensitivity - Potential Gender Differences?

The effect of stretching on range of motion is believed to rely upon an increased tolerance to stretch. This suggests, that pain modulation has significance in regards to the effect of stretching.

Study Overview

• Status: Completed
• Conditions: Range of Motion, Articular; Muscle Stretching Exercises
• Intervention / Treatment: Other: Muscle stretching exercises

Detailed Description

Given that there may be differences in the way men and women perceive a painful stimulus, this suggests that there may be potential gender differences in the tolerance to stretch following stretching.
