[Bone maturity and physical performance].

We have examined the relation between physical performance (as measured with the CAHPER tests), bone age (Greulich and Pyl's wrist evaluation) and dental age (Garn's method). Our study included 164 boys and 149 girls aged from 7 to 11. In spite of interesting significant simple correlation between most of the CAHPER tests and bone age measurements for the pre-pubescent period, the latter remains of negligible value in predicting physical performance in the studied children when variables like chronological age, body height and body weight are already included in the prediction equation.
