초록

Purpose: This study set out to investigate the effects of prone hip extension with knee flexion (PHEKF) exercisesaccording to external load on the thickness of the gluteus maximus (Gmax) and biceps femoris (BF).
Methods: Twenty-three healthy men participated in this study. All subjects randomly practiced PHEKF under the burdenof external loads created by sandbags (0 kg, 1 kg, and 2 kg). Rehabilitative ultrasound imaging (RUSI) was used tomeasure the thickness of the Gmax and BF during the PHEKF with different external loads.
Results: The thickness of the Gmax was highest during the 2 kg resistance exercise and lowest at 0 kg. The thicknessof the Gmax was significantly increased at 1 kg and 2 kg compared to 0 kg and significantly increased at from 1 kgto 2 kg (p < 0.05). The thickness of the biceps femoris was highest at 0 kg and lowest at 2 kg. The thickness ofthe biceps femoris muscle was significantly reduced at 1 kg and 2 kg compared to 0 kg (p < 0.05), but there wasno significant difference between 1 kg and 2 kg (p > 0.05).
Conclusion: The thickness of the Gmax was increased by applying PHEKF with a higher external load, whereas themuscle thickness of the biceps femoris decreased. These results suggest that the application of external loads duringPHEKF exercises may be an effective method for selective strengthening of the Gmax.
