Abstract

Purpose: Ischemic preconditioning enhances exercise performance. We tested the hypothesis that ischemic preconditioning would improve intermittent exercise in the form of a repeated sprint test during cycling ergometry.Methods: In a single-blind, crossover study, 14 recreationally active men (mean ±...
