The present study was performed to determine whether differences in non-exercise daily energy expenditure (Md,ne) exist between trained and untrained individuals. The data from seven cross-country skiers were compared with those from eight sedentary men. Daily energy expenditure (Md) was determined using the heart rate-oxygen consumption relationship; resting metabolic rate (Mr) was measured using indirect calorimetry. A physical activity questionnaire and ratios of Md or Md,ne to Mr were used as indices of physical activity. Md and Mr were significantly higher in the trained subjects whereas Md,ne was identical in the two groups. The ratio of Md,ne to Mr and the data from the physical activity questionnaire showed that there was no significant difference in daily energy expenditure and physical activity pattern during the non-exercise time. These results suggest that the exercise-induced increase in daily energy requirements is not compensated by a more sedentary life during the other daily activities in these trained men.
本研究旨在确定受过训练的个体与未受过训练的个体之间在非运动日常能量消耗（Md,ne）上是否存在差异。将7名越野滑雪运动员的数据与8名久坐男性的数据进行了比较。使用心率与耗氧量的关系来确定每日能量消耗（Md）；使用间接量热法测量静息代谢率（Mr）。将体力活动问卷以及Md或Md,ne与Mr的比值用作体力活动指标。受过训练的受试者的Md和Mr显著更高，而两组的Md,ne相同。Md,ne与Mr的比值以及体力活动问卷的数据表明，非运动时间的每日能量消耗和体力活动模式没有显著差异。这些结果表明，在这些受过训练的男性中，运动引起的每日能量需求增加并未因其他日常活动中更多的久坐生活方式而得到补偿。
