What this study is about
Obesity is a health condition caused by excessive accumulation of body fat. This condition is linked to the development of chronic diseases and also places increased stress on the respiratory system, leading to respiratory disorders, exacerbation of preexisting respiratory conditions, and a decline in physical capacity and exercise tolerance. Respiratory muscle training has been shown to have beneficial effects on respiratory function in these patients, although the effects this strategy has on other metabolic and physiological aspects related to exercise and obesity that are affected remain unclear.

Full registry criteria
Treatments and study arms
Institutionalized therapeutic exercise
Physical exercise program for cardiometabolic rehabilitation (institutionalized) with aerobic training starting with intensities of 50% to 54% of Heart Rate Reserve from week 1 to 4, increasing from 54% to 60% from week 5 to 8 and from 60% to 65% from week 9 to 12, with volumes of 10 minutes the first week and 20 minutes from week 2 to 12, neuromuscular training with intensities of 40% to 70% of 1RM estimated by OMNI RES scale with volumes of 10 to 15 repetitions 3 to 4 sets, 3 times per week.
Inspiratory muscle training
Inspiratory muscle training using a pressure threshold system exerciser with an initial intensity of 30% of maximum inspiratory pressure, increasing the pressure by 10% every 2 weeks until reaching 60% with a volume of 3 sets of 10 repetitions, 5 times per week for 12 weeks.
simulated inspiratory muscle
Inspiratory muscle training with sham device, 5 times a week for 12 weeks.
Primary outcomes
Maximum inspiratory pressure (MIP) is the maximum level of pressure applied to the lungs during inhalation. In normal breathing, this value reflects a negative pressure in centimeters of water (cm H₂O).
Sleep apnea is a potentially serious sleep disorder in which breathing stops and starts repeatedly. They are measured with sleep tests that measure heart rate, oxygen levels, airflow, and breathing patterns. The Apnea-Hypopnea Index (AHI) is a measure of the number of times a person stops breathing (apnea) or has shallow breathing (hypopnea) per hour of sleep. A higher AHI indicates greater severity, with typical ranges classifying the condition as mild (5-15 events/hour), moderate (16-30 events/hour), or severe (more than 30 events/hour).
Number of sit-to- stand repetitions done in 1 minute (STS-1m). A 46-cm high chair will be used.
The six-minute walking test (6MWT) will be used to determine walking distance, in meters (m), covered during six minutes. A 20-meter indoor corridor will be used and patients will be encouraged to walk as much as possible during that time.
