- Scientific TitleThe GRONORUN 2 study: is a preconditioning program for novice runners effective in preventing running related injuries? A randomized controlled trial.
- ACRONYMGRONORUN 2
- hypothesisA preconditioning program with a gradual increase of biomechanical load, prior to the start of a training program, will result in a reduction in running related injuries in novice runners compared to the control group.
- Healt Condition(s) or Problem(s) studiedPrevention, Running related injuries
- Inclusion criteriaHealthy novice runners between 18 and 65 years of age.
- Exclusion criteria1. Running experience in the last 12 months prior to the start of the study;

- Brief summaryRunning is a popular form of recreational exercise. Although running has positive effects on health and fitness, the risk of a running related injury (RRI) has to be considered. The incidence of RRI’s is high and varies from 30-79%. In novice runners an RRI can negatively affect future physical activity, so the prevention of running injuries especially in novice runners is important. High quality studies on the prevention of RRI’s are scarce. When conducting a randomized controlled trial (RCT) it is important that the intervention can be implemented in the real world, has a good compliance and will be adopted by runners and coaches.
Therefore in this two-arms RCT we propose a preconditioning program of 4 weeks prior to a 10 week training program in a group of novice runners compared to a 10 week training program without preconditioning. We hypothesize that the novice runner can adapt more gradually to the high mechanical loads of running and therefore will be less susceptible for sustaining a RRI. The concept of preconditioning is already proven in other preventive sports injuries research.
In the long follow-up period, valuable information will be gathered for a better understanding of modifiable risk factors in running-related overuse injuries.
