The power capacity of weightlifting athletes (WA) depends on muscular force; short leg length and high arm muscle are (AMA) may help. Objective: To record anthropometric characteristics, to evaluate somatotype of young male WA from Merida, Mexico, and to compare with other studies from Mexico and abroad. Methods: A cross-sectional study was carried out in August 2019. Young adult male WA (n=25) from the Sports Institute of Yucatan who participated in the international level championships in the recent years were selected in the weight categories between 67 kg and 81 kg, following International Weightlifting Federation guideline. Anthropometric measurements included height, sitting height (SH), weight, skinfolds (biceps, triceps, subscapular, iliac crest, supraspinale, medial calf), girths (flexed and relaxed mid-upper arm, calf) and breadths (bi-epicondylar humerus and femur). Subischial leg length (SLL) is the difference between height and SH. Body fat (%), AMA, height-weight-ratio and somatotype (endomorphy, mesomorphy, ectomorphy) were calculated. Results: Mean values (standard deviation) of age, body weight, height, SH, and SLL were 21.87 (3.59) years, 73.28 (8.25) kg, 165.72 (5.95) cm, 84.25 (4.53) cm, and 81.38 (3.70) cm respectively. Height-weight-ratio and body fat (%) were 39.72 and 12.44%. The athletes were endomorphic mesomorph; mean values of somatotype were 3.23 (0.93) – 5.98 (2.36) – 0.79 (0.47) (endomorphy – mesomorphy - ectomorphy). Mesomorphy shows significant correlation (p<0.05) with SLL (r= -0.472) and AMA (r= 0.751). Conclusion: In comparison with reported data from the USA and other Latin American countries, the WA from Yucatan show higher endomorphy, mesomorphy, and lower ectomorphy.
