Tournament play
Matches were played on a full-sized grass pitch under the control of a FIFA-accredited referee. The total playing time for each match was 90 min and matches one, three, and four were played as two 45-min halves with a 10-min half-time break. Because of environmental conditions (see Table 1), match two was played as four 22.5-min quarters with a 5-min break between quarters to reduce the risk of heat injury to participants. The participants completed a standardized pre-match warm-up and post-match cool-down routine under the direction of the coach. Seven of the 20 participants sustained minor soft tissue injuries during match-play that prevented them from continuing the match. These players were substituted and their data were not used in the
final analyses.
