Serum CPK and Creatinine Changes During Plyometric Training in Collegiate Athletes

This retrospective study evaluated the effects of an eight-week lower body plyometric training program on serum creatine phosphokinase (CPK) and creatinine levels in male collegiate volleyball players. Sixty two players were divided into experimental and control groups. CPK and creatinine were measured at baseline and multiple time points during training. The study assessed whether plyometric training produced harmful biochemical changes or signs of rhabdomyolysis.
