目的：探討高負荷阻力運動、高負荷阻力配合低加壓壓力運動，以及中負荷阻力配合高加壓壓力運動等三種型式運動，對於運動前後最大等長與等速肌力和神經肌肉的立即影響。方法：15名一般健康男性（年齡：19.8±0.4歲，身高：171.1±1.2公分，體重：67.3±2.0公斤），依平衡次序原則，分別接受：（一）高負荷阻力（highresistance exercise, HR, 70% 1RM）；（二）HR+低加壓（high resistance exercise combined with low occlusion, HRLO, 70% 1RM + 70%收縮壓, systolic blood pressure, SBP）；（三）中負荷阻力+高加壓（medium resistance exercise combined high occlusion, MRHO, 40% 1RM + 130% SBP）。阻力運動以雙腿斜坐推蹬方式（5組，12次，組間休息1分鐘）；加壓於雙腿大腿近端（加壓與放鬆時間同阻力運動）。比較運動前與運動後的肌力與神經肌肉徵招變化差異，收取股外側肌與股內側肌的表面肌電圖，並以均方根振幅（root mean square, RMS）處理，將股外側肌與股內側肌的RMS平均值代表下肢肌群神經肌肉徵招。結果：肌力部分，最大等長肌力其HRLO下降程度顯著大於HR與MRHO（p＜.05）；神經肌肉表現部分，最大等長肌力與等速肌力其均方根振幅增加程度，HRLO顯著大於HR與MRHO（p＜.05）。結論：（一）從事高負荷阻力運動可以配合低加壓壓力來增加神經肌肉招募的量。（二）中負荷配合高加壓壓力與高負荷阻力運動在神經肌肉招募情形一致。
