| 研究実績の概要 |
The proposed research is to better understand the mechanisms of hamstring strain injuries. The specific aims are: 1) to examine the load distribution between the individual hamstring muscles at different levels of muscle activation and contraction modes (concentric, isometric, and eccentric), 2) To examine the effect of neuromuscular fatigue on load distribution between hamstring muscles at different contraction modes. The third and final aim has been slightly amended based on the findings of the previous studies and now focuses on the examination of the site-specific (proximal-middle-distal) differences in localised strains between hamstrings during isometric and eccentric contractions. In FY2017 and 2018, the first two aims were addressed while the final aim will be investigated in FY2019.

理由
The data collection and analysis of the previous two studies has been completed. For the first study, an abstract has already been submitted (review pending) to the XXVII Congress of the International Society of Biomechanics/ 43th Annual Meeting of the American Society of Biomechanics, while an abstract of the second study is currently being prepared for submission to the Rocky Mountain Muscle Symposium 2019. In addition, manuscripts for both studies are in preparation.

| 今後の研究の推進方策 |
In FY2019, the pilot testing and main data collection for the final study will be completed (May-mid August) followed by data analysis which is expected to be completed by late September. In the remaining months, a manuscript of the final study will be prepared.
