  Objectives: Rhythmic gymnastics is an Olympic sport that demands high training volume from early age. We investigated the extent of, and risk factors for, injuries among competitive Norwegian rhythmic gymnasts. Methods: One hundred and seven of 133 (80.5%) female rhythmic gymnasts (mean age: 14.5 years (SD 1.6), mean body mass index: 18.9 (SD 2.2)) participated. All gymnasts completed a baseline questionnaire and the ‘Triad-Specific Self-Report Questionnaire’. Injuries, illnesses and training hours were recorded prospectively for 15 weeks during preseason using the ‘Oslo Sports Trauma Research Center Questionnaire on Health Problems’ (OSTRC-H2). Results: Response rate to OSTRC-H2 was 97%. Mean overuse and acute injury prevalence were 37% (95% CI: 36% to 39%) and 5% (95% CI: 4% to 6%), respectively. Incidence was 4.2 overuse injuries (95% CI: 3.6 to 4.9) and 1.0 acute injuries (95% CI: 0.5 to 1.6) per gymnast per year. Overuse injuries in knees, lower back and hip/groin represented the greatest burdens. Previous injury increased the odds of injury (OR 30.38, (95% CI: 5.04 to 183.25)), while increased age (OR 0.61 per year, (95% CI: 0.39 to 0.97)) and presence of menarche (OR: 0.20, (95% CI: 0.06 to 0.71)) reduced the odds of all injuries and substantial injuries, respectively. Conclusions: Overuse injuries were common among Norwegian rhythmic gymnasts. Younger gymnasts had higher all-injury risk. Gymnasts who were not menstruating had higher substantial injury risk. Injury prevention interventions should start at an early age and focus on preventing knee, lower back and hip/groin injuries.

  Urinary incontinence (UI) is common among exercising women, but no studies have been found in rhythmic gymnasts. The aims of the present study were to investigate the prevalence and risk factors for UI in rhythmic gymnasts and the impact of UI on performance. This was a cross‐sectional study including all rhythmic gymnasts competing at the highest national and international level in Norway. One hundred and thirty‐three gymnasts from 22 sports clubs were invited to participate. Background data and possible risk factors were collected via electronic questionnaires. UI was assessed by Urinary Incontinence short form (ICIQ‐UI SF). The "Triad‐specific self‐ report questionnaire" was applied to assess the female athlete triad. Joint mobility was assessed by Beighton score. Logistic regression analysis was used to assess possible risk factors. One hundred and seven nulliparous rhythmic gymnasts (80.5% response rate) from 21 sports clubs, with mean age of 14.5 (SD 1.6) years, participated in the study. Thirty‐four (31.8%) reported UI with 21 (61.8%), 3 (8.8%), 6 (17.6%), and 4 (11.8%) reporting stress, urgency, mixed urinary incontinence, and leakage for no obvious reason, respectively. BMI, hypermobility, menarche, disordered eating, and hours of training were not found to be risk factors for stress urinary incontinence. Twenty‐four gymnasts with UI (70.6%) reported incontinence to influence sports performance; 10 (29.4%) reported to be afraid of visible leakage and 5 (14.7%) that the leakage would happen again. Seventy‐four (69.1%) had never heard about the pelvic floor. In conclusion, UI is common in rhythmic gymnasts and may influence sports performance.
