The objective of this study was to assess the thoracic kyphosis ThKA and lumbar lordosis LLA in healthy young adults and to investigate potential relationships between spinal curvatures, self-reported physical activity PA , and somatic parameters.
The study included female students and male students aged Female students with ThKA within normal values reported a significantly higher amount of low-intensity PA compared to those with ThKA below or above the norm.
Maintaining a healthy body composition may be instrumental in mitigating the risk of developing spinal curvature abnormalities. Human posture depends on a variety of factors such as age, gender, somatic parameters, physical activity PA , mental condition, occupation, condition of the muscular and nervous system, and genetic factors 1 , 2 , 3 , 4 , 5 , 6 , 7.
Body posture undergoes permanent changes, both during ontogenetic development and in the circadian rhythm. Normal posture is characterized by the symmetrical alignment of the pelvis, shoulders, and scapulae in the frontal and transverse planes. In the sagittal plane, the spine has four physiological curves, i. These curvatures are geometric parameters that have an impact on the mechanical properties and load balance of the intervertebral tissues 6 , 8. The normal shape of spinal curvatures is very important due to the load on passive spinal structures, pelvic alignment, and the prevention of pain.
