| Summary: | 碩士 === 國立體育大學 === 教練研究所 === 95 === The purpose of this study was to investigate the effect of 20 days vibration training and jump rope training on baseball players’ lower limbs’ power (CMJ), take-off reaction time, base-running velocity from home to first after batting and 5m base-running velocity after batting of baseball players. Twenty-six adult baseball players (excellent university and substitute service of professional baseball teams) were involved in this study with the average age and height weight were 2.3±2.46yr、174.6±4.51cm、and 79.23±7kg, respectively. Pretest (T-1) included 4 tests. The CMJ and take-off reaction time was basic test of sport capacity, base-running velocity from home to first after batting and 5m base-running velocity after batting were specific test of sport capacity. Subjects was divided to group A (vibration training) and group B (jump rope training by CMJ performance in matched-pair designed ( each group have 13 people). Group A and B started 20 days training, there were 4 times training in 10 day and separated at least 1 day. Group A were stimulated by vibration frequency at 40Hz, and amplitude at 2mm, in 2 movements of vibration training and proceeded 5 sets, each set performed 60s, and set rested 40s. Group B proceed 2 sets × 5 times × 10s of jump rope training by personal best performance, set rest interval was 2 min, and each time rest 30s. Middle-test (T-2) was proceeded in 10 days and posttest (T-3) was proceeded after training. Results showed that CMJ of Group A and B had significant improvement after 20 days training (p<0.001、p<0.01), but there was no difference between groups. Reaction time of Group A and B were significant improvement (p<0.001), but there was no difference between groups. Base-running velocity from home to first after batting of group A and B were significant improvement (p<0.001) and group A was significant higher than group B to 0.32 m/s (p<0.05); 5m base-running velocity after batting of group A was significant improvement (p<0.01), but group B was not significant improvement and group A was significant higher Group B in 0.34 m/s (p<0.05). Conclusions of the study were vibration and jump rope training can improve CMJ, take-off reaction time, base-running velocity from home to first after batting, 5m base-running velocity after batting, but base-running velocity from home to first after batting and 5m base-running velocity after batting were significant different between groups.
