Effect of air resistance on the metabolic cost and performance of cycling
- 292 Downloads
The metabolic cost (VO2) of cycling against a range of wind velocities (VW) was studied in a wind tunnel of 15 male cyclists and the results compared with work on a stationary cycle ergometer, uphill cycling on a treadmill, and performance times in road racing competitions.
The results suggested that the relative aerobic power output (% VO2 max) which could be sustained for a given time by elite cyclists, is similar to that found previously for marathon athletes. However, due to the differences in the non-drag component of the work for given metabolic cost the cyclist will travel approx. 2 1/2 times the distance of an endurance athlete.
