Objectives To quantify the changes in work done by lower limb joint moments during maximal speed running following a sports-specific repeated protocol. Design Observational with repeated-measures. Methods Recreational athletes (n = 18 (9 females), aged 26.2 ± 6.2 years) performed 12 30-m sprints on non-motorised treadmill. Three-dimensional kinematics and ground reaction forces were subsequentl...
