| Résumé |
In many endurance sports, a large part of an athlete’s external power is used to overcome drag. This force has two components: friction and pressure drag. When the athlete’s velocity is very low, friction drag dominates. In normal sports activities, pressure drag dominates. However, frictional drag is influential in the velocity range in which the airstream changes from laminar to turbulent, which on the other hand depends on the roughness of the athlete’s clothing.
The term ‘drafting’ is mainly used in sports physiology and biomechanics to describe the tactic of performing a mode of activity in sheltered position. Therefore, the growing success and impact of merging endurance sports where athletes could take advantage in drafting raised renewed questions on the physiological characteristics and mechanisms regulating the human locomotion in sports like running (Pugh, 1971) , cycling (Kyle, 1979), speed-skating (Rundell, 1996), swimming (Chatard & Wilson, 2003), triathlon (Hausswirth et al. 1999). The athlete who drafts continuously during the race may therefore reach a better position than would normally be in line with his individual physiological capacities. For this reason, many athletes attempt to position themselves behind athletes of the same or slightly better ability.
