Sports clubs and team games in the Netherlands are suffering because of increased pressures on teenagers to succeed academically, Gabrielle van Doorn of the Royal Dutch Hockey Association told delegates.
Hockey was experiencing a high drop-out rate between the ages of 14 and 18 and team games generally were less popular against individual sports such as running, windsurfing and roller-skating.
Ms van Doorn said sports clubs were responding by encouraging teenagers to devise their own physical education curriculum.
