Quadricepts and hamstrings of bicyclists and non-bicyclists: A comparison of isokinetic torque values

1 May 1989


The purpose of this study was to measure and compare the isokinetic torque values and ratios of the quadriceps and hamstrings of bicyclists and non-bicyclists at 60, 180 and 240 degrees per second. More normative isokinetic data of specific populations is needed for developing injury prevention programs and for establishing appropriate rehabilitation and training goals. The hypothesis was that the torque/body weight values for the quadriceps of bicyclists would be larger than the quadriceps torque/body weight values of non-bicyclists. The hamstring/quadriceps ratios for bicyclists would then be smaller than the ratios for non-bicyclists. Unpaired t-tests showed no significant results between bicyclists and non-bicyclists for the torque/body weight values of the quadriceps and hamstrings and for hamstring/quadriceps ratios. Some significant results were found when the higher competitive level bicyclists were compared to non-bicyclists and to lower competitive level bicyclists.
