The biomechanics of head-first versus feet-first sliding.
The two basic sliding techniques, head-first and feet-first, were analyzed kinematically with high speed cinematography. Four phases were identified with each technique: sprint, attainment of sliding position, airborne, and landing. The velocity and displacement of the center of gravity were measured with each technique. The study was primarily descriptive but demonstrated potential for injury with each technique. Further studies are needed to determine which technique is safer and faster.
