Based on the wind-tunnel measurements of five sprinting postures of exceptional male and female professional cyclists, Crouch et al. For example, sprint riders in competition always adopt a more aggressive sprint position for a final sprint, for which the torso is lowered to reduce the frontal area and create a more streamlined torso geometry. Additionally, substantial efforts have been made to understand the correlation between drag and specific rider configurations.

For example, research has been extended to understand the aerodynamics of more complex multi-rider configurations, including tandem para-cycling, drafting and cycling peloton.

Practically, the results are valuable for optimizing the posture and improving skin-suit design for drag minimization.Īfter the fundamental work of characterizing the flow structures around a rider, much effort has been channeled into advancing our understanding of cycling aerodynamics.

This study reveals the inter-relationship between leg position and riding posture and suggests that the flow associated with varied leg position should include surrounding geometrical components to obtain and understand the full aerodynamic impact. The comparison shows that the effect of leg position on drag is not consistent between the two riding postures, as the altered flow associated with different leg positions is influenced by the wakes from and proximity of other upstream or nearby components, such as the arms. To address this question, we compare the impact of leg position for two elite-level riding postures: the standard sprint and pursuit body positions. Previous studies have shown that cycling aerodynamic drag is sensitive to leg position during the pedaling cycle however, a systematic analysis comparing the impact of leg position between different riding postures is yet to be undertaken. As such, much effort has been channeled into understanding the detailed flow around cyclists, since small gains can produce large rewards. Aerodynamics is an important factor affecting cyclist performance, as at the elite level 90% of rider energy is used to overcome aerodynamic drag.
