Objectives:
To compare temporal and pressure values between racewalking and normal walking (freely selected speed) and evaluate the impact of racewalking on normal walking.
Design And Participants:
Temporal and plantar-pressure values were recorded (xPression system) during normal walking and racewalking in 8 high-level racewalkers. The Wilcoxon test was used for comparisons.
Measurements:
Duration of walking and racewalking cycle phases (seconds and percentage of the cycle), peak and average pressures under the hind foot and metatarsal heads, and pressure distribution (%) among metatarsal heads.
Results And Conclusions:
Normal walking: temporal parameters similar to those described in normal gait; peak pressures higher than those described in nonracewalkers with displacement toward lateral forefoot. Racewalking: shorter cycles (important decrease of midstance phase); higher peak pressures than during normal walking in the hind foot and 4th and 5th metatarsal heads; average pressures similar to normal walking in hind foot and lower in forefoot; pressure displacement toward lateral forefoot greater than in normal walking.
