    Abstract

    © 2014 Sports Medicine Australia. Objectives: Repeated-sprint ability appears to be influenced by oxidative metabolism, with reductions in fatigue and improved sprint times related to markers of aerobic fitness. The aim of the current study was to measure the oxygen uptake (V˙O2) during the first and last sprints during two, 5. ×. 6-s repeated-sprint bouts. Design: Cross-sectional study. Methods: Eight female soccer players performed two, consecutive, 5×6-s maximal sprint bouts (B1 and B2) on five separate occasions, in order to identify the minimum time (trec) required to recover total work done (Wtot) in B1. On a sixth occasion, expired air was collected during the first and last sprint of B1 and B2, which were separated by trec. Results: The trec was 10.9±1.1min. The V˙O2 during the first sprint was significantly less than the last sprint in each bout (p
