Phosphocreatine is a substance that is fundamental to the ability of the body to produce muscular energy.
Elevated blood levels of creatine kinase are indicative of muscle damage.
The study investigated the association of statin treatment on recovery from exercise. The study included ten patients, (who were subject to a four-week regimen of statin therapy), who had their phosphocreatine and creatine kinase levels measured pre- and post-statin therapy.
The study found:
(a) Phosphocreatine levels took 97% longer to recover from exercise after statin therapy.
(b) Creatine kinase levels rose by 17.7% after statin therapy.
The results of the study suggest that statin therapy may impair energy production and promote muscle damage.
