Investigation of The Effect of Thoracic Kyphosis Degree on Physical Activity Level and Respiratory Function Tests

Abstract

Long sitting time and physical inactivity due to technological advancements may lead to an increase in thoracic kyphosis. The aim of this study was to investigate the effect of thoracic kyphosis degree on physical activity and respiratory function tests in healthy subjects. Methods: A total of 54 healthy individuals (35 female, 19 male, mean age: 21.37±1.63 years) were included in the study. Thoracic kyphosis degree was measured by inclinometer. Respiratory volumes were evaluated using a respiratory function test device. Physical activity level was assessed by International Physical Activity Questionnaire (IPAQ). Results: It was found negative correlations between thoracic kyphosis degree and maximum voluntary ventilation (r=-0.278, p<0.042). There was correlation between the maximal inspiratory pressure and physical activity level (sitting time) (r=-0.270, p<0.05). Conclusion: Increase in kyphosis degree in the thoracic region causes a decrease in maximal respiratory capacity and muscle endurance. We believe that it is important to encourage healthy individuals to engage in physical activity as well as stretching and posture exercises to reduce kyphosis degree in order to improve respiratory parameters.

Effect of adding diaphragmatic breathing to corrective exercises on kyphotic angle and diaphragmatic excursion in postmenopausal kyphotic women: A randomized controlled trial

“…This reduces lung volumes and creates a mechanical disadvantage for the diaphragm, decreasing contractibility (Ciloglu et al., 2020). This mechanical disadvantage, combined with the biomechanical changes to the ribcage that alter diaphragm length‐tension properties and weaken its contractile force generation, significantly impacts respiratory function (Özler & Bakirhan, 2020). Furthermore, the rigid kyphotic posture limits thoracic expansion during inspiration, overloading accessory inspiratory muscles and potentially leading to respiratory muscle failure (Sato et al., 2021).…”

Cumulative Effects of Concurrent Inspiratory Muscle Training and Postural Correction Bands on Older Individuals Community Dwellers: A Randomized Study

“… 3 4 Both aging and thoracic kyphosis alter the movement of the thoracic cage, reducing the rib cage’s range of motion and subsequently causing declines in lung capacity and respiratory muscle strength. 5 6 To address these issues, posture correction measures are necessary through respiratory muscle training (RMT) to prevent the decline in respiratory muscle function.…”
