摘要

運動後會引起骨骼肌血流量的立即變化，進而影響運動後骨骼肌恢復、修補及增生。本研究目的為探討增強式跳躍對運動後最大攝氧量與股四頭肌血液動力學之影響。本計畫募集10名大專女子籃球選手為受試者，實驗採交叉實驗設計，將所有受試者均進行增強式跳躍與一般跳躍，經過一週後兩組交換進行相同流程。進行增強式跳躍或一般跳躍，跳躍前與跳躍運動後4小時，檢測受試者股四頭肌血液動力學及最大攝氧量。本實驗結果發現跳躍運動後4小時，增強式跳躍組股四頭肌總血紅素（增強式跳躍組：27.0 ± 3.5 μM vs. 一般跳躍組：20.6 ± 2.4 μM）、帶氧血紅素（增強式跳躍組：18.0 ± 2.6 μM vs. 一般跳躍組：13.0 ± 1.6 μM）及去氧血紅素（增強式跳躍組：9.1 ± 1.1 μM vs. 一般跳躍組：7.7 ± 0.8 μM）顯著高於一般跳躍組，而增強式跳躍組的最大攝氧量顯著高於一般跳躍組（增強式跳躍組：34.5 ± 1.4 ml/kg/min vs. 一般跳躍組：32.6 ±1.5 ml/kg/min）。本研究結論為增強式跳躍運動在運動恢復後，可明顯提高作用肌群之血流量，該現象可能有助於受試者維持較高的最大攝氧量。

Acute exercise is able to changes muscle blood flow rapidly, which may affect muscle tissue repair process during post-exercise recovery. The purpose of this study was to determine the effect of plyometric jumps on postexercise maximal oxygen consumption and hemodynamic response in the quadriceps muscle of female basketball players. Ten women's college basketball players participated in this cross-over study. Participants in respective trials performed both plyometric depth jumps (PDJ) and double-leg tuck jumps (DLTJ) exercise. Each trial was separated with at least one week interval. Maximal oxygen consumption and changes in hemodynamics data of quadriceps were collected before and 4 hours after the jump exercise. We found that the PDJ trial had significantly greater total hemoglobin (PDJ: 27.0 ± 3.5 μM vs. DLTJ: 20.6 ± 2.4 μM), oxygenated hemoglobin (PDJ: 18.0 ± 2.6 μM vs. DLTJ: 13.0 ± 1.6 μM) and deoxygenated hemoglobin (PDJ: 9.1 ± 1.1 μM vs. DLTJ: 7.7 ± 0.8 μM) levels compared to DLTJ trial after 4 hour recovery. Moreover, the maximal oxygen consumption was significantly higher in PDJ trial than DLTJ trial (PDJ: 34.5 ± 1.4 ml/kg/min vs. DLTJ: 32.6 ± 1.5 ml/kg/min). This study concludes that players in PDJ trial showed a greater maximal oxygen consumption than players in DLTJ trial after 4 hour recovery. This improvement might be due to a greater effect of PDJ exercise on enhancing muscle blood flow during post-exercise recovery.
