摘要
自 Francis Galton 提出利用双生的研究方法,可使人们认识先天遗传与后天环境之间的关系以来,各方面学者对人体之间的种种差异(包括形态、生理、心理等),获得一些新的认识。我们在学校体育卫生的实际工作中。
An investigation on 11 indices for sport capabilities was carried out in 437 twin pairs of primary and middle school pupils in 1982 and 1983 in three districts of Shenyang city, Liaoning Province. The results showed that the difference in indicies was small and more concentrated between monozygotic twins while in dizygotic ones it was large and more scattered. All the indicies were related to heredity and three situations were revealed according to the calculated magnitude of heredity coefficient:Hereditary factor influenced strongly on morphological indices of the body build; moderately on dash and spring abilities; and weakly on physiological functions, pliability and toughness. The results of this study could be used as a scientific basis for physical education, directional training and selection of qualified sportsmen.
