Brief Summary

The aim of this study is to investigate the effect a specific exercise program on the incidence of injuries in the lower extremity. 72 elite orienteerers, aged 18-40 years, are allocated to an intervention or control group. The intervention group performs four specific exercises, four times a week (10 minutes per session) in conjunction with normal training. Injury data are collected every second week using valid injury questionnaire distributed by text messages over 14 weeks. Primary outcome is number of substantial injuries in the lower extremity. Secondary outcomes are incidence of ankle sprains and the average substantial injury prevalence across the 10 weeks.

Intervention

EXPERIMENTAL

The intervention consists of an exercise program developed by the medical team of the National Federation of Orienteering. Specifically, it consists of four exercises targeting strength, flexibility and coordination of the lower extremity. The orienteerers are asked to perform the exercises four times a week throughout the entire study period. The exercises are heel rises, runners pose, single leg stance and one-leg jumps with three difficult levels aiming to mainly improve lower extremity strength and neuromuscular function (online supplement). Each second week the exercises' difficulty level is increased.

Other: Exercise program

Control

NO INTERVENTION

Normal training, no intervention
