Withdrawal predictors among physical and performance characteristics of female competitive gymnasts

Future drop-outs (n = 27) and continuing (n = 41) female competitive gymnasts were compared with respect to their physical, performance and injury characteristics measured through a large battery of tests completed while they were participants in competition. Included were anthropometric variables, body composition and somatotype, strength, flexibility, endurance, power, speed and balance measurements, and previous injury information. Differences were examined through t-tests and through discriminant analyses of principal components. The results indicate that the drop-outs were as a group distinguishable from the continuing gymnasts: they were significantly older, taller and heavier which may account for the finding that they were significantly stronger, more powerful and faster, and had greater endurance. They also had a slightly more linear/ectomorphic physique with less muscularity, and performed better on most flexibility tests. Only in a gymnastic-specific flexibility variable did the continuing gymnasts out-perform the drop-outs. It was concluded that it was mainly the age factor, and presumably the social and psychological factors associated with it, that distinguished the future drop-outs from the continuing gymnasts, and that factors related to the physical make-up and performance capacities of gymnasts cannot readily predict withdrawal from the sport.
