Correlation between maximal oxygen consumption (O2Peak) measured during an incremental exercise test and recovery constants for muscle oxygen consumption recovery (mO2) measured using NIRS in gastrocnemius (a) calculated after 30 s of plantar flexion and wrist flexors (b) calculated after 30 s of handgrip exercise at 50% of MVC in the high‐fitness (dark grey) and low‐fitness (light grey) group
