Book excerpt: The purpose of this thesis was to investigate the hypothesis that significant differences may exist in the heart rate and oxygen uptake responses of several individuals to work performed on the bicycle ergometer and motor-driven treadmill. Specifically, the problem was to determine whether or not maximal heart rate, maximal oxygen uptake, and the heart rate concurrent with a half maximal oxygen uptake differed significantly for work performed on each apparatus. The Astrand-Ryhming nomogram was evaluated in. reference to their supposition that ". . .as test work a . . . treadmill test or cycle test may be chosen" (5:221). The experimental group was comprised of twenty subjects who were randomly selected from a finite population of males registered for the first time in the Faculty of Physical Education at the University of Alberta. Approximately equivalent work load increments were initially estimated for both apparati such that any possible effect of procedure on the results obtained might be minimized. Within the limits of the sample tested and the reliability of procedures employed, statistical analysis justified the following conclusions: that significantly higher values of maximal heart rate and maximal oxygen uptake are elicited by treadmill as compared to bicycle ergometer exercise; and that the heartrate concurrent with a half maximal oxygen uptake does not differ significantly between the two types of apparatus.
