研究概览
简要总结
The study will be looking at acute changes in Achilles tendon properties and changes in a vertical single leg hop following an exercise intervention. The three exercise interventions will be randomized and take place on separate days 1 week apart. The three exercise interventions are AAROM, slow load, and plyometrics.
详细描述
The purpose of the study is to determine if there are acute changes in Achilles tendon properties and changes in performance based on what tendon exercise intervention is being used. About 70 people will take part in this research.
