Abstract：
A secular trend can be observed throughout the world with an increase in childhood obesity and a decrease in fitness. The research aimed to examine the results of tests measuring the conditional abilities of young boys aged 14-18 in fitness tests and their correlations with body composition indicators. That was supported by research that has been prepared in Hungary so far. This research focuses on the results of fitness tests conducted on 14- to 18-year-old boys, presented along with body composition data. The authors sought to describe the development of the fitness profiles of males at a Budapest secondary school participating in the research, based on the results of the Hungarian National Student Fitness Test (NETFIT®), and also how their physical characteristics affect the results of NETFIT® tests in the sample measured. A total of 735 male high school students at a Budapest secondary school (14-18 years old) (mean ± SD, 16.05 ± 1.18 years) participated in the survey. The data were collected in the 2018/2019 academic year, and it was compared with the national data. The correlation between the performance indicators of the NETFIT® tests and the physical characteristic indicators was analyzed using the two-block Partial Least Squares method. In the resulting groups, Kruskal-Wallis variance analysis was performed to investigate the differences in performance. In contrast, pairs of group differences were tested with the Mann-Whitney test. Boys with a short physique were at some advantage in trunk-lifts and push-ups, compared to taller boys. It was also obvious that being overweight is a hindrance regarding the PACER test or the standing broad jump. The handgrip in the left and right hand was mostly of similar strength or weakness. Tall-heavy children performed better in this test. The grip strength of tall-thin students was also strong, but not as strong as in the tall-heavy group. Reducing the percentage of body fat (PBF) and creating the optimal BMI index is important for the younger age group, as our results have clearly demonstrated that overweight is a hindrance in the PACER, VO2 max, standing broad jump, back-saver sit-and-reach, and push-up tests.
摘要：
随着儿童肥胖的增加和健康的下降，在全世界都可以观察到长期趋势。该研究旨在检查测试结果，该测试测量了14-18岁年轻男孩在适应性测试中的条件能力及其与身体成分指标的相关性。到目前为止，匈牙利准备的研究支持了这一点。这项研究的重点是对14至18岁男孩进行的体能测试的结果，与身体成分数据一起呈现。作者试图描述参与这项研究的布达佩斯中学男性健身状况的发展，根据匈牙利全国学生体质测试（NETFIT®）的结果，以及它们的物理特性如何影响所测量样品中的NETFIT®测试结果。布达佩斯中学（14-18岁）共有735名男高中生（平均值±SD，16.05±1.18年）参加了调查。数据是在2018/2019学年收集的，并与国家数据进行了比较。使用两块偏最小二乘法分析了NETFIT®测试的性能指标与物理特性指标之间的相关性。在由此产生的群体中，进行Kruskal-Wallis方差分析以研究性能差异。相比之下,成对的组差异用Mann-Whitney检验进行检验。体格矮小的男孩在后备箱提升和俯卧撑方面有一些优势，与更高的男孩相比。同样明显的是，超重是PACER测试或站立跳远的障碍。左手和右手的手柄大多具有相似的力量或弱点。身材高大的孩子在这项测试中表现更好。高个子学生的握力也很强,但不像高个子那样强壮。降低体脂百分比（PBF）并创建最佳BMI指数对于年轻年龄组很重要，正如我们的结果清楚地表明，超重是PACER的障碍，VO2最大值,站立跳跃，后盾坐着，和俯卧撑测试。
