| Outline of Final Research Achievements |
The purpose of this study was to compare adductor muscles of the hip with the gluteus maximus (GM) and the hamstrings in terms of how these muscles generate extension torque during antigravity movement and to assess whether or not the hip adductor muscles plays a role as a primary antigravity muscle. Squatting activities were selected for an anti-gravity movement. Kinematic data were taken with a motion capture system and floor reactions were recorded with force plates. We determined muscle torques by optimization calculation. The skeletal model used was SIMM. GM and the Adductor magnus (AM) of the hip adductor muscles exerted greater hip extension torques than did hamstirngs. Given that the antigravity function of the AM is more like that of the GM than of the hamstrings, the AM might more appropriately be considered a primary antigravity muscle than an ancillary one.
