We investigated whether passive leg cycle exercise (PLE) for the elderly and patients with spinal cord injuries leads to the modulation of autonomic nervous activity in 5 elderly subjects. All subjects were informed consent and participate voluntarily in this study. To evaluate changes in autonomic nervous activity during PLE, we used autoregressive (AR) power spectra of pulse interval variability (PIV) corresponded to R-R interval variability and systolic blood pressure variability (SPV). Our results showed that LF and HF powers and the ratio power (LF/HF) of PIV reflecting cardiac sympathetic, parasympathetic tone and sympatho-vagal balance were not changed during PLE, but during recovery period immediately after PLE, LF and HF powers and total power of PIV was significantly (p<0.05) increased. On the pother side, LF power of SPV showing vasomotor sympathetic tone was significantly (p<0.05) decreased. We also evaluate the effect of PLE for five consecutive days to the walking rhythm. The velocity of walking after PLE was 1. 2-1. 5 times higher than that before PLE. We conclude that PLE may be used as the useful exercise for the elderly who need some therapeutics without the abrupt modulation of autonomic nervous activity.

我们调查了老年人和脊髓损伤患者的被动腿部循环运动 (PLE) 是否会导致 5 名老年受试者的自主神经活动调节。所有受试者均知情同意并自愿参与本研究。为了评估 PLE 期间自主神经活动的变化，我们使用了与 R-R 间隔变异性和收缩压变异性 (SPV) 相对应的脉搏间隔变异性 (PIV) 的自回归 (AR) 功率谱。我们的结果表明，低频和高频功率以及反映心脏交感神经、副交感神经张力和交感迷走神经平衡的PIV功率比（LF/HF）在PLE期间没有变化，但在PLE后立即恢复期间，低频和高频功率以及PIV总功率显着增加（p<0.05）。另一方面，显示血管舒缩交感神经张力的 SPV 的 LF 功率显着降低（p<0.05）。我们还评估了连续五天的 PLE 对步行节奏的影响。 PLE 后行走的速度为 1. 2-1。比 PLE 之前高出 5 倍。我们的结论是，PLE 可用作需要某些治疗的老年人的有用运动，而不会突然调节自主神经活动。
