A secondary objective was to compare if these perceptions differed between teams with a lower\u2010than\u2010average and higher\u2010than\u2010average hamstring injury burden.<\/jats:p><\/jats:sec><jats:sec><jats:title>Methods<\/jats:title><jats:p>The CMOs of eleven European professional women\u2019s football clubs were initially asked to suggest modifiable risk factors for hamstring injury. These risk factors were rated in according with their perceived importance on a 5\u2010graded Likert scale. Participating teams were divided in two groups depending on their hamstring injury burden during the 2020\/21 season. The LOW group consisted of six teams that had a lower\u2010than\u2010average hamstring injury burden. The HIGH group consisted of five teams that had a higher\u2010than\u2010average hamstring injury burden.<\/jats:p><\/jats:sec><jats:sec><jats:title>Results<\/jats:title><jats:p>Twenty\u2010one risk factors were suggested, most of which were extrinsic in nature, hence associated with the coaching staff, the team or the club organization rather than with the players themselves. The risk factors with the highest average importance were: \u201clack of communication between medical staff and coaching staff\u201d and \u201cload on players\u201d (each with a weighted average of 3.9), followed by \u201clack of regular exposure to high\u2010speed football actions during training\u201d and \u201cplaying matches 2\u20133 times a week\u201d (weighted average of 3.8 and 3.7). Differently from the LOW group, the HIGH group perceived the coaching factors (style of coach leadership, training\/exercise surveillance by coaching staff) as more important.<\/jats:p><\/jats:sec><jats:sec><jats:title>Conclusion<\/jats:title><jats:p>In accordance to the eleven CMOs recruited in this study, most risk factors for hamstring injuries are extrinsic
