在哺乳动物中，雄性的性状变异通常比雌性大。然而，到目前为止，主要只有形态特征进行了研究。能量消耗代表多种身体、生理和行为特征的代谢成本。能量消耗可以通过累积效应表现出特别高的雄性变异，如果这些性状大多表现出更大的雄性变异，或者如果它们中的许多不表现出更大的雄性变异，则缺乏雄性变异。能量消耗变化的性别差异很少被探讨。我们分析了成年人（1494名男性和3108名女性）能量消耗的大型数据库，以调查人类是否在能量消耗的个体间变异程度上进化出性别差异。我们发现，即使在统计学上比较相同年龄、身高和身体成分的男性和女性，男性在总能量、活动量和基础能量消耗方面的差异也要大得多。然而，随着年龄的增长，总能量消耗的变化减少，因为这在男性中发生得更快，更大的男性变化的幅度，虽然仍然很大，但在老年组中减弱。男性在总能量消耗和活动能量消耗方面的差异较大，这可以用男性在日常活动水平上的差异较大来解释。男性在基础能量消耗方面的差异明显更大，这至少可以部分地解释为男性在能量需求器官大小方面的差异更大。如果能量消耗是女性在选择性伴侣时间接感兴趣的一个特征，这将表明能量消耗是在性选择之下。然而，我们提出了一种新的能量模型，表明它也有可能是女性一直处于稳定的选择压力下的中间基础能量消耗，以最大限度地提高可用于繁殖的能量。
In mammals, trait variation is often reported to be greater among males than females. However, to date, mainly only morphological traits have been studied. Energy expenditure represents the metabolic costs of multiple physical, physiological, and behavioral traits. Energy expenditure could exhibit particularly high greater male variation through a cumulative effect if those traits mostly exhibit greater male variation, or a lack of greater male variation if many of them do not. Sex differences in energy expen- diture variation have been little explored. We analyzed a large database on energy expenditure in adult humans (1494 males and 3108 females) to investigate whether humans have evolved sex differences in the degree of interindividual variation in energy expenditure. We found that, even when statistically comparing males and females of the same age, height, and body composition, there is much more variation in total, activity, and basal energy expenditure among males. However, with aging, variation in total energy expenditure decreases, and because this happens more rapidly in males, the magnitude of greater male variation, though still large, is attenuated in older age groups. Considerably greater male variation in both total and activity energy expenditure could be explained by greater male variation in levels of daily activity. The considerably greater male variation in basal energy expenditure is remarkable and may be explained, at least in part, by greater male variation in the size of energy-demanding organs. If energy expenditure is a trait that is of indirect interest to females when choosing a sexual partner, this would suggest that energy expenditure is under sexual selection. However, we present a novel energetics model demonstrating that it is also possible that females have been under stabilizing selection pressure for an intermediate basal energy expenditure to maximize energy available for reproduction.
