摘要

目的：監控活動量能讓球員及教練明確知道比賽累積下的負荷，幫助球員避免傷害，近年來足球與橄欖球開始利用方便且精準的加速規監測球員的活動量，相比之下排球運動缺乏相關的運動監控。方法：本實驗讓不同位置的排球選手在各種運動情境下（比賽、模擬賽以及練習）配戴加速規以監控活動量，並且比較位置間和不同運動情境下的加速規數據的差異，探討加速規應用在排球上的可行性。結果：發現所有位置過半的活動皆為低強度運動。其中，舉球員在比賽時的活動量最高，自由球員休息時間則最長皆符合排球的技術特徵。結論：利用加速度訊號量化活動量與運動強度，能分辨出不同位置的球員在不同的情境下之間的差異，這些差異也符合過去研究指出的排球運動特徵，可見加速規量化排球運動的可行性。

Purpose: Monitoring the amount of activity allows players and coaches to clearly know the cumulative load of the matches and help the players avoid injury. In recent years, soccer and football have begun to monitor the amount of player activity with accelerometers, which are convenient and accurate. In contrast, volleyball still lacks of related sports monitor. Method: The purpose of this study was to test the feasibility of its application in volleyball. Participants of different positions wore accelerometers on the outside ankle during one match, one scrimmage match and one practice. Result: The result was comparable to prior research on the characteristics of motion in volleyball, in which low intensity activity occupied more than 50% of physical activities across all positions. The setter had the highest physical demand in the match and the libero had the most amount of rest. Conclusion: Using the acceleration signal to quantify the player load and exercise intensity, the difference between players in different positions in different situations can be distinguished. These differences are also consistent with the characteristics of volleyball movements pointed out in previous studies, and the feasibility of quantifying volleyball by accelerometers can be seen.
