Purpose To develop a bioenergetic model representing the dynamics of metabolic power—including aerobic, anaerobic lactic, and anaerobic alactic contributions—during 100–400 m sprints. This study calculates maximum anaerobic capacities using sprint data and assesses the model’s ability to predict performance across various sprint distances. Methods Sprint energetics were estimated applying di Prampero et al. (J Exp Biol 208:280...
