Summary:The objectives of this study were to develop normative tables to classify judo athletes by maximal isometric strength and muscular power, and to compare performance at different competitive levels. 102 male athletes performed tests of maximal isometric handgrip strength (MIHS), scapular humeral traction (MISHT), lumbar traction (MILT), lower body traction (MILBT), plyometric push-up (PPU), countermovement jump (CJ) and squat jump (SJ). Performance was classified as: ≤ 10th percentile = very poor, 11–25th percentile = poor, 26–75th percentile = regular, 76–90th percentile = good and > 90th percentile = excellent. Classification relative to body mass [isometric (kg/kg) and power (cm kg)] was as follows: MIHS—very poor: ≤ 0.81; poor: 0.82–0.96; regular: 0.97–1.51; good: 1.52–1.79; excellent: ≥ 1.80, MILT—very poor: ≤ 1.14; poor: 1.15–1.41; regular: 1.41–2.0; good: 2.0–2.5; excellent: ≥ 2.6, MILBT—very poor: ≤ 1.15; poor: 1.16–1.44; regular: 1.45–2.15; good: 2.16–2.62; excellent: ≥ 2.63, MISHT—very poor: ≤ 0.34; poor: 0.35–0.41; regular: 0.42–0.62; good: 0.63–0.73; excellent: ≥ 0.74, PPU—very poor: ≤ 635.4; poor: 635.5–901.9; regular: 902.0–1801.4; good: 1801.5–2369.7; excellent: ≥ 2369.8, SJ—very poor: ≤ 1690.7; poor: 1690.8–1990.3; regular: 1990.4–3387.9; good: 3388.0–4029.4; excellent: ≥ 4029.5 and CJ—very-poor: ≤ 1775.4; poor: 1775.5–2195.4; regular: 2195.5–3667.2; good: 3667.3–4208.3; excellent: ≥ 4208.4. State athletes had lower MISHT ( p  = 0.015) than international athletes and lower CJ than national athletes ( p  = 0.05). International athletes showed better PPU performance than others ( p  < 0.05). MIHS, MISHT and PPU were sensitive to identify differences between competitive level of judo athletes (state, national and international level).
