广西汉族和壮族大学生肺活量与肌肉参数的相关性分析

目的 探讨广西某高校汉族、壮族大学生肺活量与肌肉参数的相关性。方法 随机抽取1909名广西某高校在读大学生，采用MC-180体成分仪测量其肌肉参数，肺活量测试仪测量其肺活量。按《国家学生体质健康标准》进行身高、体重测试。将受试者肺活量分数分为4组：<60分、60～79分、80～89分、≥90分。采用SPSS 23.0统计学软件进行分析。结果 不同肺活量分数段汉族男、女大学生身高、年龄、体重、身体质量指数（BMI）、肌肉参数存在组间差异（均P<0.05），壮族女大学生身高、体重、BMI、肌肉参数（除左上肢肌肉量）存在组间差异（均P<0.05）；汉族男大学生身高、肌肉参数最大值主要集中在≥90分组，呈上升趋势，汉族、壮族女大学生身高、体重、BMI、肌肉参数在<60分、60～79分、80～89分组上升趋势，在≥90分组各指标略有下降，壮族女大学生左上肢肌肉量组间差异不明显。汉族男、女大学生年龄、身高、体重、BMI、肌肉参数与肺活量成显著正相关（均 r>0，均 P<0.01）；壮族男、女大学生身高、体重、肌肉参数与肺活量成显著正相关（均 r>0，均 P<0.01），左上肢肌肉量与肺活量相关性不显著（P>0.05）。结论 年龄、身高、体重、BMI、肌肉参数的增加对两民族大学生肺活量的增加有一定正性作用，左上肢肌肉量的变化对壮族大学生肺活量的影响不明显，汉族大学生各肌肉参数与肺活量的相关性强于同性别壮族大学生。

Correlation of spirometry and muscle parameters of college students of Han and Zhuang nationalities in Guangxi#br#

Objective To analyse the correlation between the vital capacity and muscle parameters of Han and Zhuang college students in a college in Guangxi.Methods A total of 1909 college students from a college in Guangxi were randomly selected to measure their muscle parameters using the MC-180 body composition meter and their vital capacity using a vital capacity tester. We carried out height and weight tests according to “National Student Physical Health Standard”. The subjects’ vital capacity scores were divided into four groups:<60 points, 60-79 points, 80-89 points, ≥90 points. SPSS 23.0 software was used for statistical analysis.Results There were differences in height, age, weight, body mass index (BMI), and muscle parameters among Han nationality male and female college students with different vital capacity scores (all P<0.05). There were a difference in height, weight, BMI, and muscle parameters between groups among Zhuang female college students (except the left upper limb) (both P<0.05); the height and muscle parameters of Han male college students were mainly concentrated in ≥90 groups, showing an upward trend. The height, weight, BMI and muscle parameters of Han and Zhuang female college students were<60 scores, 60-79 points, and 80-89 groups showed an upward trend. The indicators in the ≥90 group decreased slightly, and there was no significant difference in the left upper limb muscle mass within Zhuang female college students. The male, female college students ’age, height, weight, BMI, muscle parameters were significantly positively correlated with vital capacity (all r>0, both P<0.01); the male, female college student’ height, weight, muscle parameters were significantly positively correlated with lung capacity (all r>0, all P<0.01), the correlation between left upper limb muscle mass and lung capacity was not significant (P>0.05).Conclusion The increase in age, height, weight, BMI, and muscle parameters has a positive effect on the increase in lung capacity of college students of the two nationalities. The change in the muscle mass of the left upper limb has no obvious effect on the lung capacity of Zhuang students. The correlation between muscle parameters and lung capacity of Han students is stronger than the same-sex Zhuang college students.
