Effectiveness of Core Exercise Program on Balance and Isokinetic Strength in Adults

다국어 초록 (Multilingual Abstract)

The purpose of this study was to develop a core exercise program for balance and lower extremity muscle strength and to evaluate its effects using biomechanical variables. A total of 26 participants were included in the study and 3 dropped out during the study. The participants who completed 8-week core exercise program were 10 in control group (CG) and 13 in exercise group (EG). Body balance and the lower extremity muscle strength were examined pre and post exercise program by using AMTI force platform and Isokinetic dynamometer. Center of pressure (COP) ranges showed a significant difference between groups (F=7.75, p=.011). There was a statistically significance in correlation effects of M/L COP velocity but not in A/P COP velocity. Hip extensor showed a significant difference between pre and post-test (F=6.82, p=.016). Participants in the EG showed statistically larger values A/P COP range, M/P COP velocity, and A/P COP velocity than in CG at pre-test (p<.05). Participants in training group decreased their level of M/L COP velocity at post-test compared with pre-test. Knee flexor in training group found to be increased after the exercise program significantly (p<.05). The correlation effect of body balance and lower extremities strength showed negative correlation between A/P COP velocity and Ankle plantar-flexor (r= -.25, p=.046). The core training was found to be an effective method for improving the balance and increasing isokinetic strength of lower extremity.
