dc.description.abstract | PURPOSE: To investigate peak oxygen uptake ([Formula: see text]) in relation to sex, age, body mass, fat-free mass (FFM), maturity, and overweight status. METHODS: Multiplicative, allometric models of 10- to 18-year-olds were founded on 1057 determinations of peak [Formula: see text] supported by anthropometry and estimates of maturity status. RESULTS: Baseline models with body mass controlled for showed age to exert a positive effect on peak [Formula: see text], with negative estimates for age2, sex, and a sex-by-age interaction. Sex-specific models showed maturity status to have a positive effect on peak [Formula: see text] in addition to the effects of age and body mass. Introducing skinfold thicknesses to provide, with body mass, a surrogate for FFM explained maturity effects and yielded a significantly (P < .05) better statistical fit in all models compared with those based on FFM estimated from youth-specific skinfold equations. With girls only, the introduction of overweight, defined by body mass index, resulted in a small but significant (P < .05) negative effect, with an age-by-overweight status interaction. CONCLUSIONS: FFM has a powerful influence on peak [Formula: see text] in both sexes. Interpretation of the development of youth aerobic fitness and its application to health should reflect the sex- and maturity-associated variation in FFM. | en_GB |
