Introduction: Thoracic kyphosis refers to the natural curvature of the upper spine, influenced by vertebral structure, intervertebral discs, and paraspinal muscle strength. Excessive curvature can impair posture, reduce mobility, and negatively affect quality of life.
Objective: The main objective of this study was to compare the impact of functional versus traditional exercise programs on postural thoracic kyphosis in young adults 19-22 years.
Methodology: Forty-five participants (21 females and 24 males) were randomly assigned to either a functional training group (core and multi-planar exercises) or a traditional training group (basic strength training). Both groups followed a 12-week program, three sessions per week. Posture was assessed using the Posture Screen Mobile application, and thoracic curvature was quantified with the Cobb angle method.
Results: After the intervention, both groups showed improvements: 3.5 degree in the functional training group and 1.6 degree in the traditional training group.
Discussion: Repeated-meaures ANOVA (F (1.44) = 21.624, p < 0.0005) confirmed a significant effect across time, with greater improvements observed in the functional training group.
Conclusions: Findings suggest that functional exercises training is more effective than traditional approaches in reducing thoracic kyphosis in young adults.
