Phosphocreatine (PCr) resynthesis is not associated with greater physical fitness (VO2 peak) or mRNA levels of mitochondrial function markers.
Improving physical fitness may not directly influence muscle recovery rates as measured by PCr resynthesis.
StrongRefutesmedium confidence
However, PCr resynthesis was not associated with greater physical fitness (VO2 peak) or messenger ribonucleic acid levels of mitochondrial function markers such as NQO1, PGC‐1α, and SIRT1.
Why this rating
Based on the analysis of associations in a study involving healthy adults.
