Abstract:	目的：本研究的目的是在探討倒立對人體心率變異度變化之差異。方法：研究對象包括體操專長大學生（n=8，20.3±1.6歲），與一般健康大學生（n=8，22.3±2.4歲）。配帶無線心率監測錶（Polar RS800）分別進行安靜休息坐姿、倒立板倒立為期6分鐘的R-R interval心率變異度資料收集，顯著水準訂為α=.05。結果：在安靜坐姿LFn.u.、LF/HF的指標分析中，一般大學生顯著大於體操專長生。而HF、HFn.u.指標方面，一般大學生顯著小於體操專長生。在倒立板倒立中，一般大學生與體操專長生的所有調查指標，皆未達顯著差異水準。在安靜時與倒立板倒立時的心率變異度分析中，一般大學生的所有調查指標，皆未達顯著差異水準。體操專長生的HF、HFn.u.指標在安靜時顯著大於倒立板倒立時，而LFn.u.、LF/HF指標方面，安靜時顯著小於倒立板倒立時。結論：在坐姿的狀態下，體操專長生有較佳的自律神經系統調控能力；在安靜時與倒立板倒立時心率變異度分析中，體操專長生呈現交感神經活動上升，而副交感神經活動下降的趨勢，有較佳的自律神經系統調控能力。 Purposes: The purposes of this study were to investigate the effects of hand-standing on heart rate variability (HRV). Methods: Eight colligate gymnasts (age: 20.3±1.6 yrs.) and 8 colligate non-gymnasts (age: 22.3±2.4 yrs.) participated in this study. The wireless heart rate monitor (Polar RS800) was applied to monitor R-R interval for 6 minutes. HRV in sitting position and hand-standing with machine. The significant level was set at .05. Results: Higher LFn.u. and LF/HF in sitting were found in non-gymnasts than in gymnasts. However, significant higher HF and HFn.u were resulted in gymnasts than non-gymnasts (p＜.05). The statistical analysis also indicated no significant main effect or interaction effect in all investigated HRV indexes in hand-standing with machine. Nevertheless, Higher HF and HFn.u. in gymnasts was found in sitting position than in hand-standing with machine. Finally, significant higher LFn.u. and LF/HF were resulted in hand-standing with machine than in sitting position (p＜.05). Conclusions: Gymnasts possess better controlling and adjusting abilities in Autonomic Nervous System during resting state and better parasympathetic activation in hand-standing with machine.
