The aim of this study was to determine which kinanthropometric and performance variables predict injuries in female netball players. In a prospective study, 72 volunteer grade A netball players (mean age 20.6 +/- 3.6 years, range 15-36 years) were measured for hypermobility, somatotype, static balance, jumping abilities and anaerobic fitness at the University of Western Australia Human Movement Performance Laboratory prior to the start of their 14-week season. Injuries were classified by site, diagnosis and severity, and were monitored throughout the entire season by the same physiotherapist at the Western Australia (WA) Matthews Netball Centre, Perth, Australia. A total of 22 injuries in 22 players were recorded, affecting the ankle joint lateral ligament complex (59%), knee ligaments (18%), back (18%) and Achilles tendon (5%). Injuries were more common among grade A1 players than other grades (54 vs 19%, P < 0.001). Within grade A1 players, the proportion of injuries decreased with age (P < 0.05). Players were more likely to have had an injury if they had better jumping ability, better anaerobic fitness and if they were low on the endomorphy somatotype scale (P < 0.05). After allowing for both jumping ability and endomorphy, there was no longer a significant difference between A1 and non-A1 players in their risk for injury. Young elite players are at a substantially increased risk of injury. This higher risk appears to be associated with--if not a direct consequence of--their being thinner, fitter and having more powerful jumping capabilities. This suggests that injury-prevention programmes should be targeted at elite players, especially the younger ones.
