The 52 teams completed the injury prevention programme in
2279 (mean 44±22 sessions, range 11–104) out of 2957 training
sessions and matches throughout the season (77%), corresponding
to 1.3 times per week. Of all the teams, 60% (n=31)
completed the injury prevention programme two times per
week or more in accordance with the recommendation. In all
tertiles of compliance, the majority of the injury prevention
sessions were conducted in the fi rst half of the season (March–
June). In this period the programme was completed in 82% of
all sessions, whereas 75% of the teams (n=39) completed the
prevention programme in 20 or more sessions (table 1). In the
second part of the season (August–October) the programme
was completed in 58% of all sessions. The difference in compliance
between the fi rst and the second part of the season
was particularly noticeable in the tertile with low compliance;
these teams completed the injury prevention programme seven
times more often in the fi rst part of the season. In the second
half of the season the teams in the lowest tertile completed the
programme in 2.4±4.1 sessions over a period of 11 weeks
