Abstract

Background: One of the components affecting the level of health is physical fitness and diets, which is also considered the foundation of a healthy lifestyle. Methods: Samples by survey ranged from 871 to 1,417 (boys) and from 843 to 1,326 (girls). Speed (5 m run), agility (figure-8-run), explosive power (vertical jump), flexibility (stand and reach) and cardiovascular fitness (step test) were measured. The Body Mass Index (BMI) of each student was classified as Thin, Normal weight or Overweight/Obese (Owt/Ob) relative to International Obesity Task Force (IOTF) criteria. Fitness items were compared among weight status groups and across surveys with sex-specific analyses of covariance. Regressions of each fitness item on the BMI in the four surveys were done using linear and nonlinear quadratic models. Results: Performances on all fitness tests except flexibility were poorer among Owt/Ob compared to Normal and Thin youth, but performances on fitness tests within weight status groups did not differ consistently across surveys. Conclusions: Relationships between the BMI and fitness tests varied across surveys, but suggested reasonably consistent cur-vilinear relationships between fitness tests and the BMI among boys more so than girls.

波兰青年的体重状况、bmi和身体健康:1986年至2016年的关系
背景:影响健康水平的因素之一是身体素质和饮食,这也被认为是健康生活方式的基础。方法:男生871 ~ 1417例,女生843 ~ 1326例。测量了速度(5米跑)、敏捷性(图8跑)、爆发力(垂直跳跃)、柔韧性(站立和伸展)和心血管健康(台阶测试)。每个学生的身体质量指数(BMI)被分类为瘦,正常体重或超重/肥胖(Owt/Ob)相对于国际肥胖工作组(IOTF)的标准。健康项目在体重状况组之间进行比较,并通过性别特定的协方差分析进行调查。采用线性和非线性二次模型对四项调查中各健康项目对BMI的影响进行回归。结果:除了柔韧性外,Owt/Ob青年在所有健身测试中的表现都比正常青年和瘦青年差,但在体重状况组的健身测试中的表现在调查中并没有一致的差异。结论:BMI与体能测试之间的关系在不同的调查中有所不同,但在男孩中体能测试与BMI之间的曲线关系比女孩更一致。
