The effect of psychological stress on resting metabolic rate (RMR) and diet-induced thermogenesis (DIT) was assessed in 12 healthy young non-obese men of body weight 70.2 +/- 1.2 kg (mean +/- s.e.m.) and age 25 +/- 0.6 years. Two types of commercially available motion pictures (video films) were shown to the subjects during the measurements, ie stress-inducing horror films and as a control, romantic family films. The study was conducted according to a cross-over design. RMR and respiratory quotients were not significantly influenced by the type of film shown to the subjects. DIT, assessed over 4 h, was significantly increased by the stress-inducing treatment, 0.95 +/- 0.05 kJ/min (mean +/- s.e.m.) versus 0.76 +/- 0.06 kJ/min (control). No significant effect was observed of psychological stress on postprandial substrate oxidation rates, nutrient balances, and urinary catecholamine excretion.
在12名体重70.2±1.2千克（均值±标准误）、年龄25±0.6岁的健康非肥胖年轻男性中，评估了心理压力对静息代谢率（RMR）和饮食诱导产热（DIT）的影响。在测量过程中，向受试者播放了两种市售电影（录像片），即诱发压力的恐怖电影，以及作为对照的浪漫家庭电影。该研究采用交叉设计。向受试者播放的电影类型对RMR和呼吸商没有显著影响。在4小时内评估的DIT，经诱发压力的处理后显著增加，为0.95±0.05千焦/分钟（均值±标准误），而对照组为0.76±0.06千焦/分钟。未观察到心理压力对餐后底物氧化率、营养平衡和尿儿茶酚胺排泄有显著影响。
