Twenty healthy adults were randomly assigned to a moderate pressure or a light pressure massage therapy group, and EKGs were recorded during a 3-min baseline, during the 15-min massage period and during a 3-min postmassage period. EKG data were then used to derive the high frequency (HF), low frequency (LF) components of heart rate variability and the low to high frequency ratio (LF/HF) as noninvasive markers of autonomic nervous system activity. The participants who received the moderate pressure massage exhibited a parasympathetic nervous system response characterized by an increase in HF, suggesting increased vagal efferent activity and a decrease in the LF/HF ratio, suggesting a shift from sympathetic to parasympathetic activity that peaked during the first half of the massage period. On the other hand, those who received the light pressure massage exhibited a sympathetic nervous system response characterized by decreased HF and increased LF/HF.
20名健康成年人被随机分为中度压力按摩治疗组或轻度压力按摩治疗组，并在3分钟的基线期、15分钟的按摩期和3分钟的按摩后期记录心电图。然后，心电图数据被用于得出心率变异性的高频（HF）、低频（LF）成分以及低频与高频比值（LF/HF），作为自主神经系统活动的无创指标。接受中度压力按摩的参与者表现出以HF增加为特征的副交感神经系统反应，这表明迷走神经传出活动增加，而LF/HF比值降低，这表明从交感神经活动向副交感神经活动的转变，在按摩期的前半段达到峰值。另一方面，接受轻度压力按摩的参与者表现出以HF降低和LF/HF增加为特征的交感神经系统反应。
