Reduced physical activity or inappropriate training can cause the development of postural abnormalities. The aim of the present study was to determine the relationship between intensive, controlled physical activity, such as karate, and postural parameters. The study group consisted of 57 young karate competitors aged 9-12 years. The control group included 76 healthy, active children in similar age. The children's posture, activity level, and time in front of electronic devices were evaluated. The following body posture assessments were carried out: Adams' test, evaluation of the plumb line, evaluation of the kyphosis, and lordosis angles using a digital inclinometer and shoulder blade position measurements using a pediscoliometer. In the majority of cases, despite evidence of an increase or decrease in the values of the plumb line and scapulae level, the results were still within the normal ranges. In 71.93% of the examined karate-training children, a decrease in torso rotation was noted. The study revealed a visible difference in postural muscle strength by the Mathiass screening test ( < 0.00001). The children in the control group spent more time in front electronic devices than the karate-training children did ( < 0.007). Postural defects regression was more often observed in the study group than in the controls ( < 10). The frequency of postural defects stabilization was also significantly higher in the study group than in the control children ( = 0.001). Conversely, postural defects progression was significantly more frequent in the control group than in young karate competitors ( < 10). These differences remained significant in subgroups of girls and boys. Physical activity performed regularly and under the direction of a professional trainer can prevent postural disorders.
体力活动减少或训练不当可能导致姿势异常的发展。本研究旨在确定像空手道这样的高强度、受控的体力活动与姿势参数之间的关系。研究组由 57 名 9-12 岁的年轻空手道运动员组成。对照组包括 76 名年龄相近、积极活跃的健康儿童。评估了儿童的姿势、活动水平和使用电子设备的时间。进行了以下身体姿势评估：Adams 测试、铅垂线评估、使用数字测斜仪评估脊柱后凸和前凸角度以及使用 pediscoliometer 评估肩胛骨位置。尽管铅垂线和肩胛骨水平的数值有所增加或减少，但在大多数情况下，结果仍在正常范围内。在 71.93%的接受空手道训练的儿童中，躯干旋转减少。Mathiass 筛选测试显示出明显的姿势肌肉力量差异（<0.00001）。对照组的儿童比空手道训练的儿童花更多的时间在电子设备前（<0.007）。研究组比对照组更经常观察到姿势缺陷的回归（<10）。研究组的姿势缺陷稳定频率也明显高于对照组（=0.001）。相反，对照组的姿势缺陷进展频率明显高于年轻空手道运动员（<10）。这些差异在女孩和男孩的亚组中仍然显著。在专业教练的指导下进行定期的体力活动可以预防姿势障碍。
