The relationship between anaerobic power and isokinetic torque outputs.
Optimal peak and mean power outputs were determined from a 30s anaerobic cycle ergometer test and compared to the isokinetic peak torque outputs for hip and knee flexion and extension. Fifteen male physical education students, mean age 20.9 yrs., mean weight 73.2 kg, performed several 30s all-out ergometer rides to determine individual power curves for the calculation of peak and mean power outputs. Isokinetic exercise at 30 degrees X s-1 for knee flexion and extension and 180 degrees X s-1 for hip and knee flexion and extension was also performed. The peak and mean power outputs were 11.66 and 9.29 watts X kg-1 respectively. Mean power correlated with isokinetic peak torque at 180 degrees X s-1 for knee flexion (r = 0.96) and extension (r = 0.87) and for hip flexion (r = 0.71) and extension (r = 0.68). Due to the significant contribution of knee and hip flexion and extension movements at 180 degrees X s-1, high intensity sports may benefit from incorporation of such movements at high velocities into resistance training programs.
