Somatotype and physical performance in a sample of university students from Madrid

A sample of 303 Madrid Complutense University students (100 males and 203 females), aged 21–29 years has been studied in order to establish the relationship between somatotype components and physical work performance. Since particular interest is focused on a possible sexual difference in that relationship, males and females were analyzed separately. Results prove the high correlation of test scores implying muscularity (hand grips, pulling strength) with the mesomorphic component of the somatotype, mainly in males. Variability in tests relative to physical totype, mainly in males. Variability in tests relative to physical fitness is mainly explained by differences in endomorphy, although regarding the step test, ectomorphy is also a factor to be taken into account in females, as well as the pulling strength in males.
