This study compared treadmill and overground racewalking kinematics among 22 elite athletes at their personal best (PB) and 85% PB speeds, revealing significant differences. Ankle dorsiflexion angle decreased at heel strike, while hip flexion angle increased, alongside greater hip angle at toe-off. Comparing PB to 85% PB, contact time and hip flexion angle at heel strike decreased, along with decreased ankle plantarflexion at toe-off, but flight time and step length at heel strike increased. This suggests treadmill racewalking, particularly at PB speeds, exhibits unique gait features, yet without significant differences in flight time and knee angle between conditions, implying no increased disqualification risk.
