| Summary: | 碩士 === 國立中正大學 === 運動競技系運動與休閒教育研究所 === 107 === Purpose: This research aims to determine the changes of vertical jump performance in the elite female volleyball players during the 13th Top Volleyball League games and the differences of vertical jump performance among the players at different positions. The differences of vertical jump performance in the players among the three match-ups were also examined. Method: Nine elite female volleyball players (age 23.4 ± 4 years, height 174 ± 9 cm and weight 66.2 ± 7.8 kg) volunteered to participate in the study. The vertical jump performance of the participants in the 13th Top Volleyball League games were recorded using a wearable inertial measurement unit. One-way ANOVA with post-hoc LSD test was used to examine the data. Results: The average number of jump per player per competition was significant differences. Middle players (69.1 ± 22.2 times) and Setters (61.6 ± 18.6 times) was higher than outside spiker (43.3 ± 14.7) and opposite players (42.2 ± 16.1 times). The Middle players (29.0 ± 4.9 %), Setters (25.97 ± 1.4 %) and outside spiker (27.2 ± 2.8 %) were significantly higher than the opposite players (17.8 ± 3.9 %).Setters was lower than the Middle players. There was a significant difference in the average maximum jump height per player per competition, and some players did not reach significant differences. The average maximum jump height of the nine competition of the Taipower Women's Volleyball Team did not reach a significant difference. The total number of jump counts varied depending on set of competitions. Conclusion: The average maximum vertical jump height of the starting players in nine games tended to be stable. The average number of jump in the Middle players was higher than Setters, outside spiker and opposite players of Taipower women volleyball team. VERT COACH can be applied in the future training to get more jumping performance data in order to grasp the player's situation and adjust the training intensity.
