ABSTRACT
SUMMARY OBJECTIVES:
The aim of this study was to examine the concurrent contributions of body size, estimates of whole-body composition, and appendicular volume in addition to participation in competitive basketball to explain inter-individual variance in anaerobic peak power output during late adolescence. The study also tested non-participation versus participation in basketball as an independent predictor of peak power output.METHODS:
The sample of this cross-sectional study was composed of 63 male participants (basketball n=32, 17.0±0.9 years; school n=31, 17.4±1.0 years). Anthropometry included stature, body mass, circumferences, lengths, and skinfolds. Fat-free mass was estimated from skinfolds and lower limbs volume predicted from circumferences and lengths. Participants completed the force-velocity test using a cycle ergometer to determine peak power output.RESULTS:
For the total sample, optimal peak power was correlated to body size (body mass r=0.634; fat-free mass r=0.719, lower limbs volume r=0.577). The best model was given by fat-free mass and explained 51% of the inter-individual variance in force-velocity test. The preceding was independent of participating in sports (i.e., the dummy variable basketball vs. school did not add significant explained variance).CONCLUSION:
Adolescent basketball players were taller and heavier than school boys. The groups also differed in fat-free mass (school 53.8±4.8 kg; basketball 60.4±6.7 kg), which was the most prominent predictor of inter-individual variance in peak power output. Briefly, compared to school boys, participation in basketball was not associated with optimal differential braking force. Higher values in peak power output for basketball players were explained by a larger amount of fat-free mass.
