摘要
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. 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. 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. Results: Sedentary adult females were endomorphic with mesomorph tendency, and had low aerobic power (27.8 ± 0.6 ml/Kg·min) and low (48.7 ± 1 Kg) grip strength. Sedentary males (young and adults) and Sports adult males were mesomorph with endomorphic tendency. Sports junior males were balanced mesomorph. Aerobic power was 54.1 ± 0.9 ml/Kg·min in sports young males, 53.8 ± 0.9 ml/Kg·min in sports adult males, 41.2 ± 4.3 ml/Kg·min in sedentary young males, and 39.5 ± 1 ml/Kg·min in sedentary adult males. 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. Step-wise multiple regression analysis of somatotype components on aerobic power revealed dominant negative contribution (P < 0.001) of endomorphy (r<sup>2</sup> = 0.57, 57%), and small but significant positive contributions of mesomorphy (0.6%) and ectomorphy (0.6%): Aerobic power = [56.1 - 4.3 (endomorphy) + (mesomorphy) + 1.4 (ectomorphy)] ± 9.1 SEE. Height and somatotype components accounted for 69% of the variance (R2) in grip strength;height had greatest contribution (60%): Grip Strength = [1.7 (Height) - 6.5 (ectomorphy) - 3.4 (endomorphy) - 2 (mesomorphy) - 200] ± 12.9 SEE. Measured variables accounted for <2% of flexibility variance. Conclusion: Endomorphy contributes greatly and negatively to variance in aerobic power. Body height was the anthropometric variable with the greatest positive association
