广西在校男大学生体能测试成绩与身体肌肉参数的相关性

探究广西医科大学在校男大学生体测成绩与身体肌肉参数的相关性,为改善大学生体质健康提供科学依据.方法 随机抽取607名广西医科大学在校男大学生作为研究对象,并采用奥美体成分测量仪(TANITA MC-180)测量肌肉量、肌肉量比值.参照国家体质健康测试标准统一测试被试的肺活量、50 m跑、1000m跑、坐位体前屈、立定跳远及引体向上的成绩.采用SPSS 20.0软件对数据进行相关分析.结果 不同肌肉量水平组男大学生BMI、肺活量及肺活量体重指数差异均有统计学意义(F值分别为228.415,10.794,40.245,P值均<0.01),即男大学生的体质量指数(BMI)、肺活量均值均为肌肉量多组>肌肉量平均组>肌肉量少组,而肺活量体重指数均值为肌肉量少组>肌肉量平均组>肌肉量多组.3组被试的立定跳远、坐位体前屈及引体向上的成绩差异均有统计学意义(F值分别为4.036,4.027,52.250,P值均<0.05),其中立定跳远、坐位体前屈成绩的均值均为肌肉量平均组最高,引体向上成绩均值肌肉量多组最低.3组被试的50m跑和1000m跑得分差异均无统计学意义.3组被试的肺活量和1000m跑成绩的及格率均达到50%以上,立定跳远、坐位体前屈和50 m跑成绩的达标率均达到87%以上,而各肌肉量水平的男大学生引体向上成绩的不及格率均高达75%以上.结论 男大学生不同的肌肉量对体测成绩有不同的影响.保持适当的肌肉量,加强锻炼身体各部位肌肉力量,对改善大学生体质健康有一定帮助.

Relationship between physical fitness and muscle parameter among male college students in Guangxi

Objective To explore the relationship between physical fitness test and muscle parameter among male college students in Guangxi.Methods A total of 607 male college students were randomly selected,whose muscle nass were measured by professional Body Composition Monitors (Tanita MC-180).According to the national standard for physical health test,vital capacity,50 meters dash,1 000-meters run,sit and reach test,standing long jump and pull-ups.Data were analyzed by SPSS 20.0 software.Results Body mass index(BMI),vital capacity,lung capacity showed significant differences in students with different muscle volume(F=228.415,10.794,40.245,P<0.01).Average BMI and vital capacity for male students was highest among high muscle group,followed by moderate and low group.Mean value of lung capacity relative body mass index was highest among low muscle group,followed by moderate and high group.Significant differences in standing long jump,sit and reach test and pull up were found in male college students with different muscle mass(F=4.036,4.027,52.250,P<0.05),and average values of standing long jump and sit and reach test were highest in moderate muscle mass group,followed by low and high group.Average values of pull up was higher in low and high muscle group than medium muscle group(P<0.05).The 50 m dash and 1 000 m run scores showed no significant differences among male students with different muscle mass.Conclusion The amount of muscle mass correlate with physical fitness among male college students.Maintaining suitable muscle mass and enhancing muscular strength would help to improve physical fitness among college students.
