Background. The search for scientific arguments for the inclusion of back health as a fundamental aspect in the contents of physical conditioning for health in Physical Education (PE) in schools has led us to search for the relationship between the resistance of trunk musculature and non-specific low back pain in 1st year compulsory secondary education (CSE) students. Methods. Three tests were used: the front bridge (FB) test, the dominant side bridge (SB) test, and the modified Biering-Sorensen test (BS). The Nordic questionnaire was used to assess back health. Results. The prevalence of low back pain in boys was 58.3% (n = 42), while in girls it was 52.7% (n = 39) with no statistically significant differences. In the general sample, the students who had lower levels of muscular resistance of the trunk were associated with poor back health, while the students with better results were associated with good back health values. Conclusions. The resistance levels of the trunk musculature can be associated with the level of back health in 1st year CSE students. At these ages there are no large differences in the level of core resistance strength between sexes thus facilitating inclusive work in PE.

体育课中躯干肌肉的调理与背部健康

背景。在学校体育教育 (PE) 中，为了将背部健康作为健康体能训练内容的一个基本方面的科学论据，我们开始寻找躯干肌肉组织抵抗力与非特异性低血压之间的关系。一年级义务教育 (CSE) 学生的背痛。方法。使用了三个测试：前桥 (FB) 测试、主导侧桥 (SB) 测试和改进的 Biering-Sorensen 测试 (BS)。北欧问卷用于评估背部健康。结果。男孩腰痛的患病率为 58.3% (n = 42)，而女孩为 52.7% (n = 39)，无统计学差异。在一般样本中，躯干肌肉阻力水平较低的学生与背部健康状况不佳有关，而成绩较好的学生则与良好的背部健康价值相关。结论。躯干肌肉组织的阻力水平可能与一年级 CSE 学生的背部健康水平有关。在这些年龄段，两性之间的核心抵抗力水平没有太大差异，因此促进了体育的包容性工作。
