The Effect of Dynamic Neuromuscular Stabilization Exercises on Respiratory Function and Movement Quality in Obese WomenAbstract
The aim of this study was to investigate the effects of dynamic neuromuscular stabilization (DNS) exercises on certain indicators of respiratory function and movement quality in overweight and obese women. In this quasi-experimental study, 36 obese women with a body mass index (BMI) greater than 29 and aged between 25 and 45 years were randomly assigned to experimental (n = 18) and control (n = 18) groups. The experimental group participated in three weekly sessions of 45 to 60 minutes of DNS training over a six-week period. Respiratory function was assessed using breath-holding tests (inhalation and exhalation phases) and respiratory rate (breaths per minute), while movement quality was evaluated using the Functional Movement Screening (FMS) test. Assessments were conducted before and after the intervention for both groups. Analysis of covariance revealed that DNS exercises had a statistically significant effect on breath-holding capacity during both inhalation and exhalation, as well as on certain movement quality indicators, including hurdle step, trunk stability push-up, rotary stability, and the total movement score (P < .001). However, no significant differences were observed between groups in respiratory rate, deep squat, in-line lunge, or shoulder mobility (P > .05). The findings suggest that DNS exercises can be effective in improving respiratory function—particularly breath-holding capacity—and certain patterns of functional movement in obese women. Given the limitations concerning some variables, future research employing more precise designs and advanced assessment tools is recommended.
