title: Effects of standing cycling and the use of toe stirrups on maximal oxygen uptake.
abstract: Twenty-eight subjects (6 normal men, 14 distance runners, and 8 rowers) were tested for maximal oxygen uptake (VO2max) and associated physiological measures during bicycle ergometer exercise with toe stirrups while standing (BEts) and during treadmill exercise (TM). Correlation between BEts VO2max and TM VO2max was high (r = 0.901, p less than 0.05). No significant difference existed between the two VO2max values (60.3 +/- 8.9 vs. 60.5 +/- 9.7 ml.kg-1.min-1; n = 28). No differences were found even when three different subgroups were separately compared. It is concluded that the higher VO2max elicited during BEts as compared with normal sitting cycling may be attributed to the increased muscle blood flow and/or involvement of a larger muscle mass, the latter being partly evidenced by the observation of greater electromyographic activity during BEts.
