1RAOS score, with 100 indicating no problems and 0 indicating severe problems. 2Sports active is based on the question: ‘Do you do any sports in you spare time?’ Rated as yes/no. 3Activity level is based on the question: ‘At what level are you practising you primary sports activity?’ With the answering categories: Sub elite, elite or exercise level. 4Hours per week is based on the question: ‘How many hours a week are you practicing your primary sports activity?’ Measured as the group average.
Methods/Hypothesis testing: RAOS, Physical activity (hours per week): Mann–Whitney u-test; SPD, Physical activity: X 2 (Pearson’s). Significant difference between groups are marked with *and written with bold.
