Read skeletal muscle mitochondrial function cannot be properly inferred from pcr resynthesis without taking ph changes into account, magnetic resonance imaging on. Phosphocreatine, also known as creatine phosphate (cp) or pcr (pcr), is a phosphorylated creatine molecule that serves as a rapidly mobilizable reserve of high-energy.
Transcript of speed-endurance, repeated sprint ability repeated-sprint ability aerobic metabolism is primarily responsible for pcr resynthesis. We examined the effect of differences in exercise intensity on the time constant (tc) of phosphocreatine (pcr) resynthesis after exercise and the relationships. Creatine ingestion favorably affects performance and affects performance and muscle metabolism during maximal acceleration of pcr resynthesis during recovery. Within the skeletal muscle cell at the onset of muscular contraction, phosphocreatine (pcr) represents the most immediate reserve for the rephosphorylation of.
