Allometric Scale Corrects Performance Outcomes in Special Judo Fitness Test

We compared results of Special Judo Fitness Test (SJFT) performance of young athletes of two different age categories after correcting body mass (BM) variations by allometric scales. Thirty young judokas (14.2±3.6 years) belonging to two age categories underwent an SJFT: under 15 (U15) years old (12.1±2.4 years; 46.5±15.6 kg; 152.4±11.2 cm) and under 21 years old (U21) (18.2±0.8 years; 77.1±23.5 kg; 174.2±8.9 cm). Allometric exponents of −0.33 and 0.67 were used to correct the influence of BM variations on SJFT performance results. After correction using the –0.33 exponent, U21 showed a higher number of throws (TNT) than U15 (85.5±9.9 and 68.8±12.0, p 0.05, respectively). In contrast, TNT normalized by the 0.67 exponent was higher in U15 than U21 (1.55±0.29 and 1.17 ± 0.25, p
