![]() ![]() For example, ectomorphs were found to have less Fat Free Mass (FFM), less Body Cell Mass (BCM) and lower absolute maximal oxygen uptake than meso- or endo-morphs. īody type has important influence on body composition. 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. 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. ![]()
