RESUMO
This study comparatively assessed the somatotype characteristics of elite male Nigerian power athletes who comprised middleweight boxers (n = 23), weightlifters (n = 18) and wrestlers (n = 21), as well as a nonathletic group (n = 19). They were aged 24-35 years. Analysis of variance and Scheffe post hoc method were used to determine significant differences in the mean somatotype ratings of the groups. Among the groups, the nonathletes (4.02) were most significantly endomorphic (p less than 0.05). The weightlifters (5.12) and wrestler (5.04) were more significantly mesomorphic (p less than 0.05) than the boxers. (3.18) and nonathletes (3.06). The wrestlers' and weightlifters' dominance in mesomorphy confirms earlier reports on the salience of mesomorphy in performing strength-related skills.

Differences in motor performance according to chronological age and gender of 341 young Nigerian children (ages 3 to 5) were examined. Motor test items designed by Morris et al. (1981) were administered to the subjects. Analysis of variance was used to determine significant differences in the motor performance of the groups. In the whole sample, more age differences than sex differences in performance were noted. Except for the balancing and running performances of the girls, a fairly linear trend of improvement with age was observed in the motor performances of the groups. At each age level the boys consistently performed better than the girls in four of the six motor tests (catching, standing long jump, tennis ball throw and speed run). Generally, the 4- and 5-year-old children performed homogeneously, with a great disparity in performance noted for the 3-year-old children. The results of this study confirm that age and sex differences in motor performance occur at early childhood. Prospective studies should seek to control the extraneous factors which influence motor development and account for the observed differences in motor performance of pre-school children.

Somatotype ratings and percentage body fat of 131 elite Nigerian male athletes, average 24.2 years of age, and belonging to badminton (n = 18), basketball (n = 30), field hockey (n = 24), handball (n = 16), judo (n = 18), and soccer (n = 25) teams were determined. Basketball, handball and soccer players were taller and heavier, and had low percent fat values as compared with the other athletic groups. Judokas and hockey players were endomesomorphs. Other sports groups were predominantly ectomesomorphs.
