영문 초록

This study was designed to determine the effects of different widths in the base of support (BOS) on trunk and lower extremity muscle activation during upper extremity exercise. Twenty-seven healthy male subjects volunteered for this study. Exercises were performed for a total of 10 trials with a load of 10 repetitions maximum (10 RM) for each of the various widths of BOS (10 ㎝, 32 ㎝, 45 ㎝). The width of a BOS is the distance between each medial malleoli when a subject was in a comfortable standing position .Electromyography was used to determine muscle activation. Surface bipolar electrodes were applied over the tibialis anterior, medial gastrocnemius, biceps femoris, rectus femoris, gluteus maximus, upper rectus abdominis, and elector spinae muscle. Electromyographic (EMG) root mean square (RMS) signal intensity was normalized to 5 seconds of EMG obtained with a maximal voluntary isometric contraction (MVIC). The data were analyzed by a two-factor analysis of variance (ANOVA) with repeated-measures (3×7) and Bonferroni post hoc test. The results were as follows: (1) There were significant differences in the width of the BOS (p=.006). (2) The post hoc test showed significant differences with the BOS between 10 ㎝ and 32 ㎝, between 10 ㎝ and 45 ㎝ and between 32 ㎝ and 35 ㎝ (p=.008, p=.003, p=.011). (3) There was no interaction with the BOS and muscle (p=.438). There were no significant differences in the muscle activation (p=.215).
