Abstract
BACKGROUND:
To our knowledge, no study has investigated the concurrent repeated, high-intensity (RHIA) and repeated-sprint activity (RSA) of intermittent team sport competition.
PURPOSE:
In this study, we report on the RSA of elite Women's football competition. In addition, we describe the nature of RHIA (e.g. striding and sprinting activities) that involve a high energy cost and are associated with short duration (i.e. ≤20 seconds) recovery periods.
METHODS:
Thirteen elite women soccer players underwent video-based time-motion analysis on 34 occasions during national and international standard matches. RSA and RHIA were defined as successive (i.e. 2) sprints, or striding and sprinting efforts that occurred with ≤20 seconds between efforts.
RESULTS:
The number of RSA and RHIA bouts performed was similar between the first and second half of matches. Sprinting and striding/sprinting durations tended to remain relatively stable irrespective of the number of efforts in a RSA or RHIA bout, or the period of play. However, recovery duration between efforts increased in the second half, and when a greater number of efforts were performed per bout.
CONCLUSION:
These findings suggest that first to second half reductions in RHIA and RSA do not occur in elite Women's soccer competition. However, players increase the amount of low-intensity recovery undertaken between RHIA and RSA efforts, most likely in an attempt to maintain RHIA and RSA performance. These findings emphasize the importance of repeated-sprint and effort ability to elite Women's soccer, and highlight the importance of training this quality to prevent reductions in performance during competitive match-play.
