Publication Epidemiology and associated injury risk factors in figure skating: A systematic review(2025) Schmidt, Natasha T.; Janse van Rensburg, Dina C.; Schoeman, Marlene; Besomi, Manuela; Jansen van Rensburg, Audrey; Garnett, Daniel; Scheepers, Susan; Viljoen, CarelObjectives To identify and critically appraise the available evidence on injury epidemiology and risk factors in figure skating. Design Systematic review. Methods Eight electronic databases were searched from inception to 01 November 2023. Studies were included if they reported injury epidemiology and/or injury risk factors in figure skating. Non-English publications were excluded. Risk of Bias of included studies was assessed using the QUIPS tool (quality in prognostic factor studies). Results This systematic review identified twenty-nine studies (n = 4202 figure skaters), with an injury prevalence of 2.1 %–34 %. An injury incidence of 1.37 injuries/1000 total training hours was reported in one study (n = 8). Three significant intrinsic risk factors (older age, previous history of stress fracture and a higher body mass) and eight significant extrinsic risk factors (training more than 12 sessions per week, skipping meals, RED-s indicators, hamstring and quadriceps immobility, training rather than competing, increased time on-ice time and boot-foot length difference) were identified from individual studies. Age, as the most studied risk factor, requires careful interpretation due to study design limitations. Limitations Existing data lacks quality of evidence and current reported injury risk factors in figure skating should be interpreted with caution. Conclusions High-quality research of injuries and injury risk factors in figure skating is scarce. The inconsistent reporting of injury data across the currently available literature due to variations in injury definition and data collection methods makes it difficult to compare and draw conclusions. A critical need exists for standardized research approaches to accurately determine the true burden of injury in this sport.Item Trail running injury risk factors: a living systematic review(2021) Viljoen, Carel; Janse, Dina; Van Mechelen, Willem; Verhagen, Evert; Silva, Bruno; Scheer, Volker; Besomi, Manuela; Gajardo, Rubén; Matos, Sérgio; Schoeman, Marlene; Jansen, Audrey; Van Dyk, Nicol; Scheepers, Susan; Botha, TanitaObjective: To review and frequently update the available evidence on injury risk factors and epidemiology of injury in trail running. Design: Living systematic review. Updated searches will be done every 6 months for a minimum period of 5 years. Data sources: Eight electronic databases were searched from inception to 18 March 2021. Eligibility criteria: Studies that investigated injury risk factors and/or reported the epidemiology of injury in trail running. Results: Nineteen eligible studies were included, of which 10 studies investigated injury risk factors among 2 785 participants. Significant intrinsic factors associated with injury are: more running experience, level A runner and higher total propensity to sports accident questionnaire (PAD-22) score. Previous history of cramping and postrace biomarkers of muscle damage is associated with cramping. Younger age and low skin phototypes are associated with sunburn. Significant extrinsic factors associated with injury are neglecting warm-up, no specialised running plan, training on asphalt, double training sessions per day and physical labour occupations. A slower race finishing time is associated with cramping, while more than 3 hours of training per day, shade as the primary mode of sun protection and being single are associated with sunburn. An injury incidence range 0.7-61.2 injuries/1000 hours of running and prevalence range 1.3% to 90% were reported. The lower limb was the most reported region of injury, specifically involving blisters of the foot/toe
