Study summary
This observational study aims to evaluate exercise capacity, pulmonary function, respiratory muscle strength, and quality of life in individuals diagnosed with schizophrenia and bipolar disorder. These psychiatric conditions are associated with sedentary lifestyles, metabolic side effects of psychotropic medications, and increased comorbidity risks, all of which may negatively impact physical fitness and respiratory health. By assessing cardiorespiratory endurance, pulmonary parameters (FVC, FEV₁), and respiratory muscle strength in this population, the study seeks to identify physiological limitations and contribute to the development of more effective rehabilitation strategies. The findings may support multidisciplinary approaches to improving physical health and overall quality of life in individuals with severe mental illness.

Primary outcome measure(s)
Maximum Inspiratory Pressure (MIP) measurement — 1st day MIP will be measured using a mouth pressure device on Day 1 of the intervention. The maximum inspiratory pressure (MIP) will be recorded in cmH₂O. Three assessments will be performed, and the highest value will be reported.
Maximum Expiratory Pressure (MEP) measured in cmH₂O — 1st day MEP will be measured using a mouth pressure device on Day 1 of the intervention. The maximum expiratory pressure (MEP) will be recorded in cmH₂O. Three assessments will be performed, and the highest value will be reported.
Forced Expiratory Volume in 1 Second (FEV1) measured in liters — 1st day FEV1 will be measured using spirometry on Day 1 of the intervention. The maximum expiratory volume in 1 second (FEV1) will be recorded in liters. Three assessments will be performed, and the highest value will be reported.
Forced Vital Capacity (FVC) measured in liters — 1st day FVC will be measured using spirometry on Day 1 of the intervention. The forced vital capacity (FVC) will be recorded in liters. Three assessments will be performed, and the highest value will be reported.
FEV1/FVC ratio measured as a percentage — 1st day FEV1/FVC ratio will be calculated using spirometry on Day 1 of the intervention.
The ratio of FEV1 to FVC will be expressed as a percentage. Three assessments will be performed, and the highest value will be reported.
Peak Expiratory Flow (PEF) measurement — 1st day PEF will be measured using spirometry on Day 1 of the intervention. The peak expiratory flow (PEF) will be recorded in liters per minute. Three assessments will be performed, and the highest value will be reported.
