![]() For endomorphy, however, heritability at adulthood may be considerably lower than reported in studies on adolescent twins. High inheritabilities for mesomorphy and ectomorphy have been reported in twin studies at adolescence and are maintained in adulthood. Correlations of somatotype components between siblings are significant, and tend to be higher in the case of mesomorphy than in the case of endomorphy which apparently depends more on environmental influences, particularly in females. Flexibility appears to be unrelated to somatotype components.īody built is to a large extent genetically determined. Body height was the anthropometric variable with the greatest positive association with the variance in grip strength. Conclusion: Endomorphy contributes greatly and negatively to variance in aerobic power. Measured variables accounted for <2% of flexibility variance. Height and somatotype components accounted for 69% of the variance (R2) in grip strength height had greatest contribution (60%): Grip Strength = ± 12.9 SEE. Step-wise multiple regression analysis of somatotype components on aerobic power revealed dominant negative contribution (P < 0.001) of endomorphy (r 2 = 0.57, 57%), and small but significant positive contributions of mesomorphy (0.6%) and ectomorphy (0.6%): Aerobic power = ± 9.1 SEE. Grip strength was 89.9 ± 1.7 Kg in sports adult males, 86.7 ± 2 Kg in sedentary adult males, 75.6 ± 2.2 Kg in sports junior males and 52 ± 9.1 Kg in young sedentary males. min in sedentary young males, and 39.5 ± 1 ml/Kg.min in sports adult males, 41.2 ± 4.3 ml/Kg.min in sports young males, 53.8 ± 0.9 ml/Kg.Sports junior males were balanced mesomorph. Sedentary males (young and adults) and Sports adult males were mesomorph with endomorphic tendency. min) and low (48.7 ± 1 Kg) grip strength.Results: Sedentary adult females were endomorphic with mesomorph tendency, and had low aerobic power (27.8 ± 0.6 ml/Kg Anthro-pometrics (height, weight, 8 skin folds, arm and calf circumferences, elbow and knee diameters), maximal exercise O2 uptake, mid trunk flexibility, right and left grip strength were measured. Methods: Healthy male (n = 226) and female (n = 86) subjects, aged 9 - 55 years, sedentary (n = 154) or participating in sports (n = 158) were studied. These data seem to suggest that the presence/absence of certain physical characteristics is crucial in the levels of motor provision in prepubescent children.Introduction and Objective: We investigated the association of endo-, meso- and ecto-morphic components of somatotype with aerobic power, mid-trunk flexibility and grip strength. The morphological typology presented more interactions with strength than % of body fat and physical activity. The mesoectomorphic boys and ectomesomorphic girls performed higher in all tests. In medicine ball throw, handgrip strength and Margaria-Kalamen power test obese children presented higher scores, followed by children who were overweight. Non obese children presented higher values for curl-ups, push-ups and standing broad jump. The associations for ectomorphy were the inverse of those for endomorphy and mesomorphy. There were negative associations for body fat, endomorphy and mesomorphy with curl-ups, push-ups and broad jump tests and positive associations with ball throw, handgrip strength and Margaria-Kalamen power tests. The physical activity assessment employed sets of curl-ups, push-ups, standing broad jump, medicine ball throw, handgrip strength and Margaria-Kalamen power stair. Physical activity was assessed with the Baecke questionnaire. Somatotype was computed according to the Carter’s method. Evaluation of body composition was done determining body mass index and body fat by means of skin-fold measurements, using the method described by Slaughter. This was a cross-sectional study design involving 312 children (160 girls, 152 boys) aged between 10 and 11.5 years old (10.8 ± 0.4 years old). The purpose of this study was to analyse the interaction between somatotype, body fat and physical activity in prepubescent children.
