The aim of this study was to assess changes in the components of physical fitness that are conducive to the health of young people surveyed between 2001 and 2020. Hypotheses were formulated about an increase in the thickness of skinfolds, especially among women, the deterioration of the results of fitness tests and the lack of conditioning of the examined changes with socioeconomic factors. Every year, physiotherapy students at the Collegium Medicum in Bydgoszcz, Nicolaus Copernicus University in Toruń (Poland) were examined for body height and mass, skinfold thickness, flexibility, static strength, abdominal muscle strength, functional strength and endurance. The results were obtained from 1161 female students and 464 male students. Similar trends were observed for most of the studied characteristics in people of both sexes. In male students, secular trends towards a decrease in the thickness of biceps skinfolds (R = 0.455, p = 0.002) and lower leg skinfolds (R = 0.314, p = 0.015) were found. In female students, secular trends towards an increase in the body mass (R = 0.41, p = 0.003), a decrease in the thickness of skinfolds over the biceps (R = 0.477, p = 0.001) and decreased flexibility (R = 0.283, p = 0.023) were found. Male sex and the thickness of suprailiac skinfolds were frequent predictors of the, assessed motor abilities and socioeconomic factors did not significantly affect their maintenance. The obtained results, except for a few secular trend examples of the somatic features (male student's age and calf skinfold, female student's body mass, male and female student's biceps skinfold) and flexibility in women, showed their stability and the lack of conditioning by social factors and by the fitness test. Attention to the appropriate level of the observed components is justified, especially in light of the identified trend that showed their deterioration.
这项研究的目的是评估有利于 2001 年至 2020 年期间调查的年轻人健康的身体素质成分的变化。研究提出了假设，即皮肤褶皱厚度会增加，尤其是女性，健身测试的结果会恶化，并且所检查的变化与社会经济因素无关。每年，波兰托伦哥白尼大学比亚威斯托克医学院的理疗专业学生都会接受身高和体重、皮肤褶皱厚度、柔韧性、静态力量、腹肌力量、功能力量和耐力的检查。结果来自 1161 名女学生和 464 名男学生。在两性中，大多数研究特征都呈现出相似的趋势。在男学生中，发现了二头肌皮肤褶皱（R=0.455，p=0.002）和小腿皮肤褶皱（R=0.314，p=0.015）厚度随时间减少的趋势。在女学生中，发现了体重增加（R=0.41，p=0.003）、二头肌皮肤褶皱厚度减少（R=0.477，p=0.001）和柔韧性降低（R=0.283，p=0.023）的随时间推移的趋势。男性性别和髂嵴上皮肤褶皱厚度是评估运动能力的常见预测因素，社会经济因素并没有显著影响它们的维持。除了少数几个身体特征（男学生的年龄和小腿皮肤褶皱，女学生的体重，男学生和女学生的二头肌皮肤褶皱）和女性柔韧性的随时间推移的趋势外，获得的结果表明它们具有稳定性，并且不受社会因素和健身测试的影响。应该注意观察到的成分的适当水平，特别是考虑到已确定的趋势表明它们在恶化。
