| Research Abstract |
The purpose of this study was to compare the recruitment patterns in hamstring muscles during hip extension exercise and during sprinting to clarify the mechanism underlying hamstring injury. We concluded that the activation properties of each hamstring muscle differ due to the muscle morphological features. These differences may contribute to the mechanism for hamstring muscle strain injury.
