Résumé : |
Objective To compare the surface electromyography (EMG) amplitude of the hip joint, including the gluteus maximus (GM), biceps femoris (BF), and semitendinosus (ST) muscles generated by three different exercises: prone hip extension (PHE), prone table hip extension (PTHE), and prone table hip extension with 90° knee flexion (PTHEK), with compensatory pelvic motions. Design Repeated-measure within-subject intervention. Participants Sixteen-healthy males (mean age = 23.4 + 2.2 years). Main outcome measures EMG was used to collect EMG signals from the GM, erector spinae (ES), BF, and ST muscles. Furthermore an electromagnetic tracking motion analysis was also performed to measure the compensations. Results EMG amplitude differed significantly among the three conditions (PHE vs. PTHE vs. PTHEK) (p 0.05). Conclusions These results suggest that the PTHEK can be recommended as an effective method to strengthen the GM muscle without increased BF or ES muscle activities and without compensatory pelvic motions. |
