Contraction intensity affects NIRS-derived skeletal muscle oxidative capacity but not its relationships to mitochondrial protein content or aerobic fitness | Journal of Applied Physiology

| American Journal of Physiology Verified
To further refine the near-infrared spectroscopy (NIRS)-derived measure of skeletal muscle oxidative capacity in humans, we sought to determine whether the exercise stimulus intensity affected the τ value and/or influenced the magnitude of correlations with in vitro measures of mitochondrial content and in vivo indices of exercise performance.

Introduction Derived from the asymptote of the hyperbolic relationship between exercise intensity and task duration, the critical intensity of exercise serves as a marker of aerobic fitness, as it represents the highest oxidative steady state for a specific mode of exercise (Ansdell et al., 2019; Burnley & Jones, 2018; Poole et al., 2016).

Effects of voluntary wheel running on mitochondrial content and dynamics in rat skeletal muscle

Abstract This study reports that in rat skeletal muscle the proteins specifically responsible for mitochondrial dynamics, mitofusin-2 (MFN2) and mitochondrial dynamics protein 49 (MiD49), are higher (p < 0.05) in oxidative soleus (SOL) muscle compared with predominantly glycolytic extensor digitorum longus (EDL) muscle, but not seen for optic atrophy 1 (OPA1; p = 0.06).
