Quantifying metabolic energy contributions in sprint running: a novel bioenergetic model.

ABSTRACT:

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 208:2809-2816, 2005) method using velocity and time-split data from the 2009 World Athletics Championships to model metabolic power over the men's and women's 100-200-400 m events. Aerobic power was modeled with an exponential function, anaerobic lactic power with a bi-exponential function, and anaerobic alactic power with a log-normal function. Maximal anaero
