| Research Abstract |
The purposes of this study were 1) to investigate the relationship between hip muscular function, change of direction (COD) test time and lower extremity movement during COD, and 2) to clarify effectiveness of hip extensor and abductor function during the change of direction performance. There were significant correlations between the COD test time and the rate of force development (RFD) in the hip extensor and abductor. RFD reflects important function in the early phase of muscle contraction (0-200ms). Therefore, this parameter in hip extensor and abductor might be related to the fast lower limb movement during COD performance.
