Acute Performance, Physiological and Perceptual Responses to Repeated-Sprint Exercise with Continuous or Intermittent Blood Flow Restriction

Introduction: Team sport athletes commonly perform repeated short-duration sprints ( ≤10 s) interspersed by brief recovery periods (≤60 s). Repeated-sprint training augments physiological determinants of repeated-sprint ability which are further improved with systemic hypoxia (i.e., reduced fraction of inspired oxygen). Blood flow restriction (BFR) is an alternative hypoxic stra tegy utilizing inflatable cuffs on the legs that limit arterial inflow of blood and mostly occlude venous return. Cuffs can be applied continuously (i.e., C-BFR), or intermittently during only work (i.e., I-BFRWORK) or intra-set rest periods (i.e., I-BFRREST).
