In training for a marathon: Runners and running-related injury prevention

Objective: To investigate which preventive measures runners use when preparing for a half- or full-marathon and whether the use of these measures at baseline and during the preparation-period differs between runners who sustained no/non-substantial running-related injuries (NSIRs) or substantial running-related injuries (SIRs). Design: Prospective cohort study. Setting: 16-week period before the Utrechtmarathon. Participants: Runners who subscribed for the half- or full-marathon. Main outcome measures: The occurrence of RRIs was registered every 2-weeks, using the Dutch version of the Oslo Sport Trauma Research Center (OSTRC) questionnaire on Health Problems. The OSTRC was used to differentiate between runners with SIRs (question 2/3 score>12) and NSIRs (question 2/3 score<13). The use of different preventive measures, was registered every 4-weeks. Results: 51.6% of the runners reported at least one RRI in the 12-months prior to this study (history of RRIs). The SIRs with a history of RRIs more often asked for running shoe advice than NSIRs with a history of RRIs (67.9%vs43.4%, P < 0.05); 18.9% of the SIRs with a history of RRIs used supportive materials for knee and/or ankle versus 0% of NSIRs with a history of RRIs (P < 0.05). Conclusion: SIRs with a history of RRIs might be using their preventive measures for symptom reduction or secondary prevention.
