The purpose of this study is to compare the muscle recovery effect of static, dynamic, PNF, and foam roller stretching after high intensity training, assessed by ultrasonography diagnostic device and electromyogram..
Participants were randomly assigned to static, dynamic, PNF, and foam roller stretching groups. Their muscle thickness and activity were assessed before training and after stretching, both by intragroup and intergroup analysis..
As a result, there were significant differences of muscle thickness and activity for every muscle in each group. In intergroup analysis, dynamic stretching group showed significant difference, while the other three groups did not..
Dynamic stretching has insignificant effect on muscle thickness and activity; static, PNF, and foam roller stretching are suggested for post-exercise, while foam roller stretching is the most recommended.
