This randomized controlled trial evaluated whether adding diaphragmatic breathing exercises to an eight-week supervised Pilates program improves pulmonary function, resting heart rate, and core endurance in sedentary women aged 35 years and older. Participants were randomized to Pilates combined with diaphragmatic breathing or Pilates alone. Both groups trained three times per week for eight weeks.
Participants were sedentary women aged 35 years and older who had not participated in regular structured exercise during the previous six months. Participants were randomly assigned in a 1:1 ratio to either Pilates combined with diaphragmatic breathing exercises or Pilates alone. Both groups completed supervised exercise sessions three times per week for eight weeks. Each session lasted approximately 60 minutes and included warm-up, main Pilates exercises, and cool-down. The experimental group additionally performed structured diaphragmatic and abdominal breathing exercises integrated into the Pilates sessions. Pulmonary function, cardiovascular parameters, functional performance, anthropometry, and echocardiographic safety parameters were assessed at baseline and after the intervention.

Participants completed a supervised mat-based Pilates exercise program three times per week for eight weeks. Each session lasted approximately 60 minutes and included a warm-up phase, a main Pilates exercise component targeting core stability, flexibility, postural alignment, and muscular endurance, and a cool-down phase.
Participants performed structured diaphragmatic and abdominal breathing exercises integrated into the Pilates sessions. The breathing protocol included slow nasal inhalation, controlled oral exhalation, abdominal expansion, segmental thoracic breathing, and guided breathing rhythm during selected Pilates exercises.

Change in Peak Expiratory Flow
Peak expiratory flow was assessed by spirometry. The change from baseline to the end of the eight-week intervention was evaluated.
Time frame: Baseline and after 8 weeks
Change in Forced Vital Capacity
Forced vital capacity was assessed by spirometry.
Time frame: Baseline and after 8 weeks
Change in Forced Expiratory Volume in One Second
FEV1 was assessed by spirometry.
Time frame: Baseline and after 8 weeks
Change in FEV1/FVC Ratio
The FEV1/FVC ratio was calculated from spirometric measurements.
Time frame: Baseline and after 8 weeks
Change in Resting Heart Rate
Resting heart rate was measured after at least 10 minutes of seated rest.
Time frame: Baseline and after 8 weeks
Change in Plank Test Performance
Core muscular endurance was assessed using the prone plank test, recorded in seconds.
Time frame: Baseline and after 8 weeks
Change in Echocardiographic Safety Parameters
Echocardiographic parameters including ejection fraction, ventricular dimensions, wall thickness, and flow velocities were evaluated for safety monitoring.
Time frame: Baseline and after 8 weeks
