Resumo
Physical exercise has been used as a tool to improve vertebral posture. However, there is still limited information about the adaptation of the geometric shape of the spinal column in different types of physical exercises. Many studies have analysed vertebral posture in static situations, but evaluating the effect of exercise movement on vertebral posture during walking can provide new insights. Therefore, the aim of this study was to identify adaptations in vertebral posture during walking and in the orthostatic position in women subjected to 8 weeks of High Intensity Interval Training (HIIT Whole Body - HWB) and Pilates. The study included 26 women aged 33.9±13.3 years, weighing 59.6±8.5 kg, and with a height of 1.63±0.06m, divided into two groups: HWB and Pilates, with 13 participants in each group. The participants underwent 8 weeks of training in each intervention, with sessions lasting 50 minutes. In the HWB group, subjective perceived exertion (PSE) was measured using the adapted Borg scale. However, it was not possible to measure PSE in the Pilates group. Vertebral posture was assessed using videogrammetry in the orthostatic position and during a walking cycle on a treadmill before and after the intervention. Regarding the interventions, the HWB group showed a significant reduction (d=1.3; p=0.0140) in the geometric curvature of the lower lumbar region during static posture, while the Pilates group exhibited an increase in thoracic kyphosis angle in the sagittal plane (p=0.0073). Results for the HWB group during walking in the sagittal plane included a significant increase in range of motion (ROM) in the lumbar region (d=1.0), a substantial increase in ROM in the thoracic region (d=3.5), and a moderate increase in ROM in the central thoracic region (d=0.7). In the frontal plane, results showed a moderate increase in ROM in the upper lumbar region (d=0.7), a significant increase in ROM in the lower thoracic region (d=1.0), and a substantial increase in ROM in the central thoracic region (d=1.2). The main results for the Pilates group during walking in the sagittal plane included a significant increase in ROM in the lumbar region (d=1.8), a substantial increase in ROM in the thoracic region (d=2.9), and a significant increase in ROM in the central thoracic region (d=1.0). In the frontal plane, results showed a substantial increase in ROM in the upper lumbar region (d=1.3), a significant increase in ROM in the lower thoracic region (d=1.5), and a substantial increase in ROM in the central thoracic region (d=1.6). This study demonstrated the ability to increase range of motion (ROM) in both frontal and sagittal plane analyses during walking following HIIT Whole Body intervention, confirming the potential of this exercise modality to promote adaptations in vertebral posture. These adaptations are of great importance for overall spinal health and for preventing issues such as stiffness, pain, and postural dysfunctions.
