AbstractThe purpose of the current article was to use allometric models to identify the best body size descriptors and other anthropometric variables, body composition, and offset maturity that might be associated with the youngsters' 50m personal-best (PB) swim speeds (m·s<sup>-1</sup>). Eighty-five competitive swimmers (male, n=50; 13.5±1.8 y; female, n=35; 12.6±1.8 y) participated in this study. Height, body mass, sitting height, arm span, skinfolds, arm muscle area (AMA), and maturity offset were assessed. Swimming performance was taken as the PB time recorded in competition, and the propulsive force of their arm (PFA) was assessed by the tied swimming test. The multiplicative allometric model relating 50m PB swim speeds (m·s<sup>-1</sup>) to all the predictor variables found percentage body fat as a negative [(BF%) β= -.121±.036;<i> P</i>=0.001], and PFA (PFA β=.108±.033;<i> P</i>=0.001) and the girl's arm span (β=.850±.301;<i> P</i>=0.006), all log-transformed, as positive significant predictors of log-transformed swim speed. The adjusted coefficient of determination, R<sub>adj</sub><sup>2</sup> was 54.8% with the log-transformed error ratio being 0.094 or 9.8%, having taken antilogs. The study revealed, using an allometric approach, that body fatness and PFA were significant contributors to 50m freestyle swim performance in young swimmers.
