Although the impact of obesity on exercise performance is multifactorial, excessive fat mass which can impose an unfavorable burden on cardiac function and working muscle, will affect the aerobic exercise capacity. Weight loss strategies, such as bariatric surgery can obviously affect both the body composition and aerobic exercise capacity. Maximal oxygen consumption ( O) is a widely used important indicator of aerobic exercise capacity of an individual and is closely related to body weight, size and composition. An individual's aerobic exercise capacity may show different results depending on how O is expressed. The absolute O and O relative to body weight are the most commonly used indicators. The O relative to fat-free mass, lean body mass or skeletal muscle mass are not influenced by adipose tissue. The last two are more useful to precisely distinguish between individuals differing in muscle adaptation to maximum oxygen uptake. The O relative to body height is used for studying growth in children. With the in-depth study of exercise capacity and body composition in obesity, the relative oxygen uptake has been increasingly reinterpreted.
尽管肥胖对运动表现的影响是多因素的，但过多的脂肪量会给心脏功能和工作肌肉带来不利负担，从而影响有氧运动能力。减肥策略，如减肥手术，显然会影响身体成分和有氧运动能力。最大摄氧量（VO₂）是广泛用于衡量个体有氧运动能力的重要指标，且与体重、体型和身体成分密切相关。个体的有氧运动能力可能会因VO₂的表达方式不同而呈现出不同的结果。绝对VO₂和相对于体重的VO₂是最常用的指标。相对于去脂体重、瘦体重或骨骼肌质量的VO₂不受脂肪组织的影响。后两者对于精确区分在肌肉对最大摄氧量适应方面存在差异的个体更有用。相对于身高的VO₂用于研究儿童的生长情况。随着对肥胖人群运动能力和身体成分研究的深入，相对摄氧量得到了越来越多的重新解读。
