Of those naturally menstruating, 46% experienced dysmenorrhea in every menstrual cycle, and 18% took painkillers during each menstruation. Regarding injuries, 42% reported at least one lower limb injury in the past 12 months, with 44% classified as severe. The most commonly affected regions were the knee (44%), ankle (31%), and upper thigh (9%). MD was associated with lower anterior cruciate ligament (ACL) injury rates (\n                      <jats:italic>p<\/jats:italic>\n                      \u2009=\u20090.04, Cramer's\n                      <jats:italic>V<\/jats:italic>\n                      \u2009=\u20090.199, 95% CI: \u2212\u221e to \u22120.09), while regular periodic health examinations (PHE) were associated with higher injury rates (\n                      <jats:italic>p<\/jats:italic>\n                      \u2009=\u20090.05, Cramer's\n                      <jats:italic>V<\/jats:italic>\n                      \u2009=\u20090.121, 95% CI: \u22120.98 to \u22120.01), particularly knee cartilage injuries (\n                      <jats:italic>p<\/jats:italic>\n                      \u2009=\u20090.001, Cramer's\n                      <jats:italic>V<\/jats:italic>\n                      \u2009=\u20090.241, 95% CI: \u22123.19 to \u22120.59).
