有关研究指出:影响身高发育的主要因素是遗传因素和后天的营养、运动及环境因素,这些因素对身高的影响比例为:遗传——占33%);营养——占31%;运动——占20%:环境——占16%。根据以上分析,可以看到影响身高的先天遗传因素仅占33%,而后天的作用和努力则占了67%。遗传因素来自父母的遗传基因。是出生之前就已经发生的,因此是无法改变的。后天的运动、营养、环境三因素可以改善,以促进身高的增长。
The study pointed out: the main factors affecting the development of height is the genetic and acquired nutrition, exercise and environmental factors, these factors on the height of the proportion of: genetic - accounting for 33%); nutrition - 31%; exercise - 20%: Environment - 16%. Based on the above analysis, we can see that the impact of height of genetic factors accounted for only 33%, and the acquired role and effort accounted for 67%. Genetic factors come from parents' genes. It happened before birth and can not be changed. Acquired exercise, nutrition, environment, three factors can be improved to promote the growth of height.
