Junior high and high school days are the time when development of mind and body is the most remarkable, and it can be said to be the transition period from child to adult. It is said that children grow taller at the highest rate ; for girls when they are in the upper grades of elementary schools and for boys when in the junior high schools. They reach almost adults'height level during the high school days. When secretion of the somatotrophin becomes active, growth of height is active too and it has a big influence on growth of mind and body. At this time physical strength and moving ability develop most remarkably and the effect of exercise is tremendous. Features of growth and development at the adolescence spurt have been reported by a lot of researchers. Similarities in build and moving ability between the twins have been also reported. However, reports about growth and development of build, physical strength and moving ability concerning twins at the adolescence spurt have been hardly given. Therefore, to make a research on that, based on the data of sports test accumulated over 9 years, I made a comparative analysis on build, physical strength and moving ability with the data of 959 twins, 149,567 junior high and high school students in the same age group and 6100 T secondary education school students. As a result, for male twins both height and weight tend to be below the national average, while for female twins height is almost the same, and weight tends to be below it. However, physical strength and moving ability tend to be almost the same, or rather above the national average although some difference can be found according to the events for both male and female twins. This paper gives a report of and discusses the result of the analysis including influence of environmental factors on development of body and mind in the adolescence.
