Playing exposure, adherence to the 11+, and injuries were recorded for female 13-year-old to 18-year-old players. Performance testing included the Star Excursion Balance Test (SEBT), single-leg balance, triple hop and jumping-over-a-bar tests.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Results<\/jats:title>\n                    <jats:p>Complete preseason and postseason performance tests were available for 226 players (66.5%).

However, significant improvements in 5 of 6 reach distances in the SEBT were found, favouring players who highly adhered to the 11+.
