Physiological and anthropometric determinants of critical power, W' and the reconstitution of W' in trained and untrained male cyclists.

Notable physiological relationships between parameters of aerobic fitness and the measurements of W' reconstitution were observed, which differed among groups. The amount of W' reconstitution and the maintenance of W' reconstitution that occurred with repeated bouts of maximal exercise were found to be related to key measures of aerobic fitness such as CP and V̇O2max. This data demonstrates that trained cyclists wishing to improve their rate of W' reconstitution following repeated efforts should focus training on improving key aspects of aerobic fitness such as V̇O2max and CP.
