Energetics (and Mechanical Determinants) of Sprint and Shuttle Running
Int J Sports Med DOI: 10.1055/a-2184-9007Unsteady locomotion (e. g., sprints and shuttle runs) requires additional
metabolic (and mechanical) energy compared to running at constant speed. In
addition, sprints or shuttle runs with relevant speed changes (e. g.,
with large accelerations and/or decelerations) are typically short in
duration and, thus, anaerobic energy sources must be taken into account when
computing energy expenditure. In sprint running there is an additional problem
due to the objective difficulty in separating the acceleration phase from a
(necessary and subsequent) deceleration phase.In this review the studies that report data of energy expenditure during sprints
and shuttles (estimated or actually calculated) will be summarized and compared.
Furthermore, the (mechanical) determinants of metabolic energy expenditure will
be discussed, with a focus on the analogies with and differences from the
energetics/mechanics of constant-speed linear running. [...] Georg Thieme Verlag Rüdigerstraße 14, 70469 Stuttgart,
