目的了解沈阳市沈北新区初三学生体能素质、肺功能水平与变化趋势,并探索体能素质与肺功能水平的相关性。方法对2014年沈北新区部分初三学生体能素质进行测量,并用《中学生体能素质评价标准评分标准(初三)》对体能成绩评分。以线性相关探索体能素质分值与肺功能之间的相关性。结果沈北新区2014年初三男女学生体能素质合格率分别为52.00%和58.80%,且与2005年相比男生合格率下降14.60%(P<0.01)。沈北新区2014年初三学生身高、体重、胸围与2005年相比均有提高。身高、体重、胸围三项中提高最少的是15岁女生组(P<0.05)。除肺活量男生组以外,沈北新区2014年初三学生各组肺功能指标均比2005年肺功能指标有所减少,减少最少的是15岁男生组(P<0.05)。体能素质得分与肺功能指标均呈正相关(r>0),且有统计学意义(P<0.05)。肺活量体重指数与体能素质的相关系数要大于肺活量与体能素质的相关系数,肺活量体重指数相关系数均大于0.80,相关性较强。结论相比于2005年,2014年沈阳市沈北新区初三男生体能素质合格率下降。2014年所有初三学生身体形态指标有所提高。2014年(除肺活量男生组以外)学生肺功能指标均下降。
Objective To understand the physical fitness, the level of lung function and the change trend of the students of grade three in Shenbei New District, Shenyang City, and to explore the correlation between physical fitness and pulmonary function. Methods The physical fitness of some junior high school students in Shenbei New District in 2014 was measured, and the score of physical ability was scored with the “Middle School Students’ Physical Fitness Evaluation Criteria (Grade 3)”. A linear correlation was used to explore the correlation between physical fitness scores and lung function. Results The fitness rates of boys and girls in Shenbei New District in the first three days of 2014 were 52.00% and 58.80%, respectively, and the passing rate of boys was 14.60% lower than that of 2005 (P <0.01). Shenbei New District in the third day of 2014, the height, weight, chest circumference and 2005 have increased. Height, weight, bust were the least improved three-year-old girl group (P <0.05). Except for boys with lung capacity, the lung function indexes of all students in Shenbei New District in the first three days of 2014 were lower than that of 2005, the least significant reduction was in the boys aged 15 years (P <0.05). Physical fitness scores were positively correlated with pulmonary function parameters (r> 0), and were statistically significant (P <0.05). The correlation coefficient of vital capacity body mass index and physical fitness was greater than the correlation coefficient between vital capacity and physical fitness, and the correlation coefficient of vital capacity index of vital capacity was greater than 0.80. Conclusions Compared with 2005, the passing rate of physical fitness of boys in Shenbei New District in Shenyang City in 2014 decreased. In 2014, the physical status of all the students in Grade 3 improved. In 2014 (except boys group), pulmonary function indexes of students decreased.
