Importance of muscle phosphocreatine during intermittent maximal cycling

To examine the importance of phosphocreatine (PCr) degradation in maintaining power output during maximal intermittent cycling, seven healthy men completed three bouts of isokinetic cycling (30 s, 100 revolutions/min) with 4 min of rest between bouts. After bout 2, blood flow to one leg was occluded by cuffing the thigh (Cuff) during the rest period to prevent PCr resynthesis while the circulation to the other leg was intact (Cont). The cuff …
