摘要

本研究之目的在分析不同最後一步助跑步幅對排球扣球起跳的影響。本研究以12名男子高中甲組球員為受試者，其年齡在17至19歲之間（平均身高186.18±6.1cm、平均體重76.6±6.3kg）。每位受試者都必須在測力板上（Quattro jump, Kistler Inc.）盡最大努力執行三種不同最後一步助跑步幅（50、100、150cm）的扣球起跳。結果顯示150cm 分最後一步的助跑之垂直總衝量（356 N-s）大於其他兩種步幅的助跑（50cm：329 N；100cm：339 N-s），而在垂直推蹬衝量方面150cm步幅顯著大於50cm步幅。

The purpose of present investigation was to quantify the differences among the maximal-effort jumping performances by volleyball player with different approach lengths of last stride. Twelve well-trained male volleyball players aged between 17 and 19 years volunteered as subjects after the informed consent obtained from all subjects (height: 186.18±6.1 cm; body mass:76.6 ± 6.3 kg ). Each subjects was required to perform a number of maximal-effort run up vertical jump on the force plate (Quattro jump, Kistler Inc.) with different lengths (50, 100, 150 cm) of last approach stride. The results indicated that total vertical impulses of length 150cm (356 N-s) were greater than other two length trials (length 50cm: 329 N-s; length 1 00: 339 N-s) although the time for total impulse were not significantly longer the others. But, the Propulsive impulse of length 150 cm was significantly greater than length 50cm.
