Brief Summary

Overweight and obesity are associated with impaired breathing mechanics, including reduced chest wall and diaphragmatic movement, decreased respiratory muscle strength and endurance, and inefficient breathing patterns. These changes may adversely affect pulmonary function, autonomic regulation, and physical capacity. This study aims to compare the effects of kettlebell swing exercise combined with breathing training versus breathing training alone in individuals with overweight or obesity. Outcomes will include respiratory muscle strength, pulmonary function, heart rate variability, and body composition. The findings may help determine whether adding kettlebell swing exercise to breathing training provides additional benefits for respiratory and cardiometabolic health in this population.

Kettlebell training; Respiratory muscle strength; Pulmonary Function; Overweight and obese

Outcome Measures

Primary Outcomes (3)

• Repiratory muscle strength

  Respiratory muscle strength will be measured using a handheld manometer (MicroRPM). Participants will be instructed to perform a maximal inspiratory effort from residual volume to assess maximal inspiratory pressure (PImax) and a maximal expiratory effort from total lung capacity to assess maximal expiratory pressure (PEmax).

  Before and after the 6 week intervention

• Heart rate variability (HRV)

  Time and frequency-domain heart rate variability (HRV) parameters will be measured using the SA-3000P analyzer.

  Before and after the 6 week intervention

• Pulmonary function test

  Vital capacity (VC), expiratory reserve volume (ERV), forced vital capacity (FVC), forced expiratory volume in 1 second (FEV₁), and the FEV₁/FVC ratio will be measured using a portable spirometer.

  Before and after the 6 week intervention

Secondary Outcomes (1)

• Body composition
