Effects of Respiratory Muscle Training in Post-bariatric Surgery Patients

Effects of Respiratory Muscle Training on Cardiovascular, Respiratory, Metabolic and Physical Exercise Capacity Parameters Related to Obesity in Post-bariatric Surgery Patients

Sponsor

Study Type

INTERVENTIONAL

Conditions

Bariatric Surgery

Summary

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.

Interventions

BEHAVIORALInstitutionalized 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.

BEHAVIORALInspiratory 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.

OTHERsimulated inspiratory muscle

Inspiratory muscle training with sham device, 5 times a week for 12 weeks.
