During the mid-season break, the training group performed 8\u2005weeks of supervised, progressive hip-adduction strength training using elastic bands. The participants performed two training sessions per week (weeks 1\u20132) with 3\u00d715 repetition maximum loading (RM), three training sessions per week (weeks 3\u20136) with 3\u00d710 RM and three training sessions per week (weeks 7\u20138) with 3\u00d78 RM. Eccentric hip-adduction (EHAD), isometric hip-adduction (IHAD) and isometric hip-abduction (IHAB) strength, and the IHAD\/IHAB ratio were measured assessor-blinded preintervention and postintervention, using reliable hand-held dynamometry procedures.<\/jats:p>\n               <\/jats:sec>\n               <jats:sec>\n                  <jats:title>Results<\/jats:title>\n                  <jats:p>In the training group, EHAD strength increased by 30% (p&lt;0.001).
