Abstract
The possibility that quadriceps strength is a limiting factor when performing maximal oxygen consumption tests on a bicycle ergometer has been introduced in previous studies. The purpose of this investigation was to determine the relationship between quadriceps strength at varying speeds of muscle contraction and aerobic capacity measured at high and low pedaling frequencies on a bicycle ergometer. Subjects were nineteen college-age males, nine of whom were competitive cyclists and ten of whom were untrained cyclists. Each subject performed two maximal oxygen consumption (VO2max) tests on a Monark bicycle ergometer. One test was at a pedaling frequency of 60 rpm while the other was performed at 90 rpm. Expired air was collected and analyzed to determine VO2max. All subjects were tested on a Cybex II dynamometer to determine maximal torque generation of their quadriceps muscles at two speeds of movement. The results showed that there was no significant (p(.05) correlation between quadriceps strength and VO2max at either pedaling frequency. The trained cyclists, as a group, did achieve significantly higher VO2max values at both pedaling frequencies when compared to the untrained cyclists. Even so, there was no significant (p(.05) difference between the quadriceps strength of the trained and untrained cyclists at either speed of movement. Therefore it would seem that quadriceps strength was not the factor which limited the performance of the untrained cyclists.
