| Summary: | 碩士 === 國立彰化師範大學 === 運動健康研究所 === 106 === Athletes nowadays were often trained with high intensity and heavy load in the preparation of competitions, and hence were frequently encountered with delayed-onset muscle soreness (DOMS). Appropriate treatment of DOMS may speed recovery, alleviate fatigue, and possibly reduce the injury risk. The purpose of this study was to investigate the effects of vibration, foam roller, and combination of both on the recovery of DOMS. 28 college students with mean age of 21.2±1.4 years, height of 174.9±5.4 cm, and body weight of 66.7±7.5 kg were recruited to join this study. They were randomly assigned to the control group (CON), vibration group (V), roller group (FR), and vibration roller group (V+FR) with 7 individuals in each group. The DOMS of the elbow flexor muscles were induced by executing an exhausted exercise consisting of repetitive eccentric contractions. Four treatments were then performed at 0 and 24 hours after the exercise. The upper arm of each subject was measured with circumference, pressure pain threshold, soreness, range of motion, and isokinetic strength at pre, post 0(D0), 24(D1), and 48(D2) hours. The data were analyzed by a two-way mixed model analysis of variance to discern the interaction of groups and times. The results showed that the V+FR treatment significantly reduced the circumference of upper arm (D0:1.062±.019, D1:1.013±.011) and raised the pressure pain threshold (D0:.832, D1:0.615±0.173) at 24 hours after exercise. The treatment also reduced pain index, increased range of motion and muscle strength, however, the differences were not significant. Based on the results, it is suggested that the treatment combining vibration and foam roller is beneficial for reducing the swelling and pain of DOMS, and may be a suitable tool for the recovery use of athletes.
