A survey on sports injuries of 2000 korfball players aged 30 years and older was carried out at the end of the indoor season of '88/'89 through a questionnaire. The data from 1139 respondents were analysed. Four years later, the same response-group was the starting-point for a follow-up study, executed at the end of the indoor-korfball season of '92/'93 (responses N=747=66%; active players and those who dropped-out in the time between '88/'89 and '92/'93). 23% of which corresponds with an injury rate of 7.2 per 1000 hours of indoor-korfball. This injury rate represented an increase on the previous study of Van Geffen et al. (1990). They found an injury rate of 5.8 per 1000 hours of indoor korfball. In this follow-up study, age and gender were not a significant factor in determining the injury rate. The most common types of injuries were strains (45%), contusions (20%) and sprains (20%). Twisting caused 27% of all injuries. Indoor korfball is a sport in which personal contact is forbidden by rules. Nevertheless, 30% of the response group's injuries were caused by means of physical contact. Most injuries caused absenteism from sports (67%; median: 4 weeks). Absence from work was a result in 17% of the cases (median: 2 weeks). In the season '92/'93 more korfball-players did their warming-up before training and competition than in season '88/'89. Furthermore, players injured in '92/'93 registered more injuries than the non-injured in the preceeding seasons. The drop-outs suffered relatively more injuries to the knee (42%) and the proportion of cartilage damage was remarkably higher. Verf.-Referat
