本研究的目的是确定高能量和高脂肪膳食的单次摄入、中等能量和高碳水化合物膳食的单次摄入以及禁食对健康年轻男性心率变异性的影响，这是涉及各种能量和营养素水平组合的主要全球饮食模式。参与者被分配到三组：高能量和高脂肪膳食组，中等能量和高碳水化合物膳食组，以及禁食组（无餐）。在饭前、饭后连续记录R-R间期。在进食前和进食后30、60、90和120分钟获得生理和心理数据。主要结果如下：（1）在禁食组中心脏的交感神经调节减少和心脏的副交感神经调节增加，这由禁食组中心率不变、低频/高频比减少和心率变异性的高频功率增加指示;（2）在摄入高能量和高脂肪膳食或中等-能量和高碳水化合物膳食，表现为高能量和高脂肪膳食组和中等能量和高碳水化合物膳食组的心率和心率变异性的低频/高频比率增加，以及心率变异性的高频功率降低;（3）高能量高脂肪膳食组和中能量高碳水化合物膳食组在进食后的生理和心理测量中表现出相似的运动。总之，摄入的高能量和高脂肪的膳食和中等能量和高碳水化合物的膳食同样激活心脏的交感神经调制，而禁食抑制心脏的交感神经调制相比，其他两个饮食组的健康年轻男性。I Physiol Anthropol 30（6）：223-231，2011 http://www.jstage.jst.go.jp/browse/jpa2 [DOI：10.2114/jpa2.30.223]
The aim of this study was to determine the effects of the single intake of a high-energy and high-fat meal, of that of a moderate-energy and high-carbohydrate meal, and of fasting, which are major global eating patterns involving the combination of various levels of energy and nutrients, on heart rate variability in healthy young males. Participants were assigned to three groups: the high-energy and high-fat meal group, the moderate-energy and high-carbohydrate meal group, and the fasting group (no meal) in a randomized crossover design. The R-R intervals were continuously recorded before and after meals. Physiological and psychological data were obtained before and 30, 60, 90, and 120 min after meal intake. The main results were: (1) decreased sympathetic modulation of the heart and increased parasympathetic modulation of the heart in the fasting group, indicated by an unchanged heart rate, a decreased lowfrequency/high-frequency ratio, and increased high-frequency power of heart rate variability in the fasting group; (2) cardiac sympathetic activation or parasympathetic withdrawal after the intake of either a high-energy and high-fat meal or a moderate-energy and high-carbohydrate meal, indicated by increases in the heart rate and the lowfrequency/high-frequency ratio of heart rate variability, and a decrease in the high-frequency power of heart rate variability in both the high-energy and high-fat meal group and the moderate-energy and high-carbohydrate meal group; and (3) the high-energy and high-fat meal group and the moderate-energy and high-carbohydrate meal group showed similar movement in physiological and psychological measurements after the meal intake. In conclusion, the intake of the high-energy and high-fat meal and the moderate-energy and high-carbohydrate meal similarly activated sympathetic modulation of the heart, whereas fasting suppressed sympathetic modulation of the heart compared with the other two eating groups in healthy young males.
