Purpose : The purpose of this study was to identify that the effect of hold-relax and active stretching on recoveries of upper trapezius and sternocleidomastoid muscle fatigue after computer work. Methods : This study was conducted by 30 volunteer at the age of 23~33(resting group=10, hold-relax group=10, active stretching group=10). The muscle fatigue measured by tracing the median frequency(MDF) decrement from power spectrum analyses of EMG signals and the data were analyzed repeated ANOVA. Result : In case of upper trapezius, there was significant difference in group I,II and group II, III. In case of sternocleidomastoid, there was significant difference in group I,II and group I,III. Conclusion : The active stretching was effective for sternocleidomastoid and the hold-relax was effective for upper trapezius and sternocleidomastoid. The hold-relax was effective better than active stretching on recoveries of muscle fatigue.
