摘要
为了探究运动干预对信息化学习环境下初中学生的肺活量、视力、坐位体前屈、呼吸频率和心理健康等5项可能的敏感指标的影响,本研究选取北京市城区和郊区2所中学的初一年级7个实验班的学生,在近两年时间里进行了3次生理、心理测试及为期8周的运动干预.采用配对样本t检验方法分析干预前、后5项指标的得分和增幅情况,并结合青少年5项指标的基本发展规律进行数据分析和解释.与运动干预前相比,运动干预后初中学生的左眼视力、右眼视力、坐位体前屈、肺活量和呼吸频率差异有统计学意义(t=-2.383、-3.136、-2.532、-2.238和-2.774,P<0.05),而心理健康差异无统计学意义(P>0.05).与运动干预前相比,运动干预后学生右眼视力和肺活量增幅差异有统计学意义(t=-3.341、2.331,P<0.05),而左眼视力、坐位体前屈、呼吸频率和心理健康增幅差异无统计学意义(P>0.05).同时将所得统计学数据与相应年龄阶段青少年5项指标的基本发展规律结合分析可得,运动干预对初中学生的左眼视力、右眼视力和坐位体前屈有显著的积极影响,但对肺活量、呼吸频率和心理健康无明显的积极影响.实践运用本运动干预方案时,可适当增加部分项目的强度和频次.
In order to explore the effects of sport intervention on five possible sensitive indicators such as vital capacity,visual acuity,sit-and-reach,respiratory frequency and mental health of junior middle school students in the E-learning environment.This study selected seven classes of junior middle school students from two middle schools in urban and suburban areas of Beijing.In two years,three physical and psychological tests were conducted on students who had used the E-learning environment for more than one semester,and eight weeks of sport intervention was conducted.Paired sample t test was used to compare the change and increase of the scores of the five indicators before and after intervention,and then data analysis and explanation were made according to the basic development law of the five indicators mentioned above of adolescents.Compared with previous exercise intervention,the left eyesight,right eyesight,sit-and-reach,vital capacity and respiratory rate of junior high school students′later exercise intervention were statistically significant(t=-2.383,-3.136,-2.532,-2.238,-2.774,P<0.05),while the difference in mental health was not statistically significant(P>0.05).Compared with previous exercise intervention,the increase of right eyesight and vital capacity of junior high school students later exercise intervention were statistically significant(t=-3.341,2.331,P<0.05),while the difference in left eyesight,sit-and-reach,respiratory frequency and mental health were not statistically significant(P>0.05).Combining the statistical data with the basic development law of the five indicators of adolescents in corresponding age stages,it can be concluded that exercise intervention had a significant positive effect on the left eyesight,right eyesight,and sit-and-reach of junior high school students,but had no obvious positive impact on vital capacity,respiratory frequency and mental health.When using this exercise intervention program in practice,the intensity and frequency of some projects can be appropriately increased.
