中等运动量对体弱学生身体的作用

本文论述了提高体弱学生体质的试验结果。说明体弱学生采用中等运动量进行长期地、有计划地锻炼,无论从学生的身体形态、机能和素质来看都能得到明显的改善。通过四学期的试验,30名学生的平均身高从166厘米提高到171.26厘米(p<0.01),体重从54.5公斤提高到58.83公斤(p<0.05);胸围从77.63厘米提高到85.2厘米(p<0.01);肺活量从3374.66毫升提高到4013毫升(p<0.01);安静时脉搏从77.63次/分降低到67.6次/分(p<0.01);引体向上从5.16次提高到15.4次(p<0.01):弹跳从40.46厘米提高到56.83厘米(p<0.01):立定跳远从196.73厘米提高到230.66厘米(p<0.01);100米快跑从16.46秒提高到13.75秒(p<0.01);1500米跑从6分零3秒提高到5分42秒(p<0.01);灵活性从11秒68提高到10秒3(p<0.01);达标人数从0提高到93%。本文对中等运动量的锻炼方法也作了详细介绍。

The Function of the Medium Range Exercise to the Students in Weak Constitution (extracts)

The article is a test report on the improvement of students health. It sho-ws that through physical training of the medium range exercise for a long time, the students in weak constitution have distinctly improved themselves in the figure, function and quality of their bodies. After four terms, the average height of 30 students rose from 166cm.to 171.26cm. (p<0.01) ; the average of their weight from 54.5kg to58.83kg. (p<0.05); the chest measurement from 77.63cm to85.2cm p<0.01); the vital capacity from 3374.66ml to 4013ml. (p<0.01); the beat of pulse at rest dropped down from 77.63 times per min. to 67.6 times per min. (P<0.01); drawing-up (on the horizontal bar) increased from 5.16 times to 15.4 times(p<0.01); spring rose from 40.46cm. to 56.83cm(p<0.01); 100 metre sprint from 16.46 seconds to 13.75 seconds (p<0.01); 1500 metre sprint from 6 minutes 3 seconds to 5 minutes 42 seconds(p<0.01); adaptability from 11.68 seconds to 10.3 seconds (p<0.01); the percentage of the students who were up to the standard of training rose from 0 % to 93%. This article also introduces in detail the ways and means of the medium range exercise.
