영문 초록

In this study, we investigate the effects of neuromuscular electrical stimulation (NMES)-induced eccentric contraction training for two weeks on muscle strength, activation level, and muscle architecture in healthy people. Six non-disabled (4 male, 2 female) volunteered to participate. The ultrasonographic images and dorsiflexion forces were measured when subjects performed the full relaxation, maximum voluntary isometric contraction (MVIC), and NMES-induced maximum involuntary isometric contraction of their tibialis anterior muscles in both pre- and post-test. After a two-week training period, the changes in the mean maximum NMES force ratio increased from 72.5 % to 88.92 %. The changes in the TA thickness during MVIC decreased significantly from 0.22 cm to 0.11 cm. The NMES-induced eccentrical contraction training described here effectively increases muscle strength with less muscle thickness changes after two weeks of training. This training technique may have a role in neuromuscular rehabilitation.
