The next step towards the prevention of running related injuries: further development of a prevention program for recreational runners

Projectomschrijving

Hardloopblessures komen zeer veel voor. Om deze blessures in de toekomst te kunnen voorkomen wordt in dit onderzoek de effectiviteit van het '10 steps 2 outrun injury' preventie programma onderzocht bij recreatieve hardlopers die deelnemen aan hardloopevenementen van Golazo Rotterdam. Primaire doelstelling van deze studie is de effectiviteit van het '10 steps 2 outrun injury' preventieprogramma, ten opzichte van geen programma, te onderzoeken op het aantal blessures die optreden bij recreatieve hardlopers die deelnemen aan evenementen van Golazo Rotterdam. In een gerandomiseerde trial worden mimimaal 3394 lopers gerekruteerd bij inschrijving van een evenement en random verdeeld over twee groepen. Aan de hand van online vragenlijsten worden alle lopers gevolgd, waarin blessures worden geregistreerd.

Eindverslag

Hardloopblessures komen zeer veel voor. Om deze blessures in de toekomst te kunnen voorkomen is, op basis van een eerdere studie waarin helaas geen effect gevonden werd op het aantal blessuers, een nieuw online preventie programma ontwikkeld '10 steps to outrun injuries' voor lopers die deelnemen aan hardloopevenementen, waaronder de Rotterdam Marathon en de City Pier City loop. Primaire doelstelling van deze studie is de effectiviteit van het '10 steps to outrun injuries' programma, in vergelijking met geen advies, te onderzoeken op het aantal blessures die optreden bij deelnemers aan evenementen van Golazo Sports. In een gerandomiseerde studie worden worden mimimaal 3394 lopers gerekruteerd bij inschrijving van een evenement en random verdeeld over twee groepen. De eerste groep krijgt een unieke toegangscode tot het online preventie programma. De tweede groep volgt de gebruikelijke voorbereiding. Aan de hand van online vragenlijsten worden alle lopers minimaal 3 maanden gevolgd, waarin blessures worden geregistreerd.

Samenvatting van de aanvraag

Background: With the increasing number of people participating in running, the number of Running Related Injuries (RRIs) also increased. With the recently performed INSPIRE trial we examined the effect of a multifactorial, evidence-based online injury prevention program on the number of RRIs in recreational runners. Though, the prevention program was not effective in the prevention of RRIs. There is therefore urgent need to further develop injury prevention for runners using the ‘lessons learned’ from the INSPIRE trial. Therefore, the overall aim of the present proposal is to further optimize and develop a running injury prevention program for recreational runners and to investigate the effectiveness of this prevention program, i.e. the ‘10 steps 2 outrun injury’, in a large group of recreational runners, with a specific focus on runners with previous injuries, participating in Golazo running events in The Netherlands. Methods: Design: randomized controlled trial Study population: Recreational runners that sign up for the organized Golazo running events Procedure: Recreational runners will be recruited parallel with the web-based registration for the running events. After completing the online baseline questionnaire, runners will be randomized into one of the two study groups using web-based randomization. Runners in the intervention group will receive an access code by email with a link to the online prevention program and download to the accompanied application. Runners randomized in the control group will not receive specific prevention advice. All runners will be followed during their preparation for the running event (minimum of 3 months), up-to one week after the event, using online questionnaires. Intervention: The ’10 steps 2 outrun injury’ prevention program follows on the earlier evaluated tailored online evidence based intervention program. With the knowledge gained in our previous performed study, we have further optimized the prevention program in order to be able to prevent running injuries and developed the ‘10 steps 2 outrun injury’ program. This online prevention program offers 10 concrete and directing advices towards runners, supported by video’s, schemes and graphics and will be available by website and web application for smartphone use. Measurements: Online questionnaires will be send to all runners at registration (baseline), 1 month before the race, 1 week before the race and 1 week after the race. The baseline questionnaire informs on demographics, running characteristics, earlier injuries and lifestyle. The follow-up questionnaires contain questions on the occurrence of injuries, injured structure, severity and medical consumption. In order to monitor training time loss due to injury and the development and progression of overuse injuries, the OSTRC Overuse Injury Questionnaire will be sent to runners weekly. The 1-week follow-up questionnaire after the running event will additionally include questions on the compliance and implementation (following RE-AIM framework and model of Rothschild) of the prevention program. Primary outcome: The difference in injury proportion between the intervention and control group in the period between the moment of registration for the trial (e.g. the running event) and 1 week after the running event. Analyses: Injury proportions of the intervention and control group will be compared by calculating the difference with 95% CI between the injury proportions. Sample Size: Based on our recently conducted RCT, an injury incidence of 37% is expected in recreational runners participating in running events in the control group. The sample size calculation is based on the subgroup analyses on runners with previous injuries. With a risk difference of 5%, a significance level of 0.05 (two-sided testing) and a power of 80%, a minimum total of 1414 runners with a previous injury in the previous 12 months should be included in the analyses. The sample size will be doubled in order to obtain enough power for the primary analyses in the entire study population. Taking a loss to follow-up of 20% into account, a total of 3394 runners (1697 in each group) should be included. Feasibility: We will closely collaborate with GOLAZO sports, the organiser of 30 large running events (250.000 participants yearly) in the Netherlands. Earlier collaboration resulted in successful recruitment and follow-up of runners. The sample size calculation of the recently performed preventive RCT was based on an inclusion of 1106 runners within a year time. Though, within 6 months’ time we had to stop recruitment because sample size already doubled, resulting in imbalance of included running distances. It is therefore likely that, using the same approach, we will be able to recruit 3394 runners within the given time frame.
