In 1991, 769 children and adolescents, 98% of the pupils in the various age groups in seven schools and ten kindergartens on Funen, were examined. Seventy-five percent of the boys and 35% of the girls over the age of ten proved to have such short hamstrings that one knee had a extension deficit without violence of > or = 40 degrees when the hip was flexed 90 degrees. More than 10% of the boys over the age of ten had an extension deficit of > or = 60 degrees. Forty-five children had a difference > or = 15 degrees between the two legs. The triceps surae muscles are too short if the corrected foot can only be pressed slowly to the right angle. This was found to be the case for 25-64% of the children from the age of three to 17. Therefore, we must conclude that it is necessary to allow time in kindergarten and school for the children to stretch their muscles a few minutes daily.
1991年，对菲英岛七所学校和十所幼儿园各年龄组98%的769名儿童和青少年进行了检查。结果发现，十岁以上的男孩中有75%、女孩中有35%的腘绳肌过短，当髋关节屈曲90度时，一侧膝关节在无暴力情况下伸展受限≥40度。十岁以上的男孩中有超过10%的人伸展受限≥60度。45名儿童的双腿之间差异≥15度。如果矫正后的脚只能缓慢下压至直角，则表明小腿三头肌过短。结果发现，三岁至十七岁的儿童中有25%至64%存在这种情况。因此，我们必须得出结论，幼儿园和学校有必要每天给孩子们留出几分钟时间来伸展肌肉。
