The purpose of this study was to examine the changes of pennation angle based on gastrocnemius stretching and additional exercise and to identify the influence of exercise on stretching effects.
Thirty healthy adults (15 males and 15 females) participated in this study. Subjects performed stretching of the gastrocnemius and additional muscle exercises. The pennation angle of the muscle was measured before and after the intervention. A paired t-test was used to compare pre-and post-intervention and an independent t-test were used to compare between interventions.
As a result of gastrocnemius stretching, there was a significant difference between pre-and postintervention (p<0.05). In addition, the results of stretching and additional muscle exercise showed significant differences in pre-and post-intervention (p<0.05). However, there was no significant difference between stretching intervention and stretching and additional exercise intervention (p>0.05).
According to the results, the effect of stretching was not decreased even if stretching and exercise were applied together. Therefore, it is considered appropriate to perform stretching and exercise together.
