The body responds to exercise training by profound adaptations throughout the cardiorespiratory and muscular systems, which may result in improvements in maximal oxygen consumption (VO₂peak) and mitochondrial capacity. By convenience, mitochondrial respiration is often measured at supra‐physiological oxygen levels, an approach that ignores any potential regulatory role of mitochondrial affinity for oxygen (p50_mito) at physiological oxygen levels.

短跑间隔训练后，线粒体氧亲和力增加，并且与峰值摄氧量的改善有关。

身体通过在整个心肺和肌肉系统中进行深刻的适应来响应运动训练，这可能会导致最大耗氧量（VO ₂峰值）和线粒体能力的改善。为方便起见，线粒体呼吸通常在超生理氧水平下进行测量，这种方法忽略了线粒体在生理氧水平下对氧的亲和力（p50 _mito）的潜在调节作用。
