Bridge exercise with isometric hip adduction. Bridge exercise with isometric hip adduction Under the same starting condition as the general bridge condition, a Swiss ball (Hygenic Corp.) was placed between the subject’s knees while maintaining 30 degrees of hip adduction. Subjects were asked to perform 30 degrees of hip adduction with the Swiss ball. To ensure 30 degrees of hip adduction was... blue Theraband (Hygenic Corp., USA), and isometric hip adduction (IHAD) with a Swiss ball (Hygenic Corp.). The muscle activities of bilateral erector spinae (ES), gluteus maximus (GM), biceps femoris (BF), and external oblique (EO) muscles during the bridge exercises were measured using sEMG.

dead-bug exercises. We also applied three different speeds to the dead-bug exercises; 60 bpm, 90 bpm, and 120 bpm with use of a metronome. The assessment of EMG was percentage of maximal voluntary isometric contraction on the rectus abdominis (RA), external oblique (EO), and internal oblique (IO). Results: EMG activation of the RA, EO and IO muscles was significantly greater at the higher speed... maximal voluntary isometric contraction on the rectus abdominis (RA), external oblique (EO), and internal oblique (IO). Results: EMG activation of the RA, EO and IO muscles was significantly greater at the higher speed (p<0.05). There was a significant increase in abdominal muscle activity during the dead-bug exercise performed with both the upper and lower extremities compared to that with only the upper extremity or the lower extremities (p<0.05). Conclusions: These findings demonstrate that... -

In this study, although not statistically significant, the muscle contraction difference in the UG is larger than that of the SG at the same knee joint angle of IO and EO at the 60 o knee joint condition of the TrA. In previous studies, the max- imum voluntary isometric contraction (MVIC) values of the muscles were measured by EMG when performing normal bridging exercise (NBE), bridging with... the SG (p<0.05). But within the UG, no significant contraction difference was shown. There was no significant contraction difference between the surface group and the unstable SG at 60° condition and at 90° condition in all measured muscles. Conclusions: The contraction difference is different for each muscle during bridge exercise with knee flexion 60° and bridging exercise with knee flexion 90°. Muscle contraction difference is generally large when exercised on an unstable surface than a... -
