Assessment of cardiovascular risk, heart rate variability, and functionality in the late postoperative period of bariatric surgery submitted to whole-body vibration exercise: A case report

Abstract

Currently, a high prevalence of risk factors for cardiovascular diseases, such as obesity, sedentary lifestyle, and poor diet, has been observed among young people. Obesity is a public health problem that directly impacts the economy. In this case study, the authors are using data from a survey of a late postoperative bariatric surgery patient. Male patient, 23 years old, obese since childhood, 186 kg [body mass index (BMI) 61], sedentary, without other comorbidities. He denies smoking. On 10/30/2019, he underwent Y gastroplasty (Gastric Bypass) with a reduction of approximately 90% of the stomach. On 09/13/2021, he started an intervention protocol through whole-body vibration (WBV). Cardiovascular risk, heart rate variability, functionality, and quality of life were evaluated in the acute phase and in the chronic phase. The training was conducted through 10 interventions with exercises on the vibrating platform. Functionality was assessed through the tests: “Timed up and Go,” Sit/Stand, 6-minute Walk Test, and handgrip strength. A 7.1% gain in functional capacity was observed, with a 37.5% reduction in perceived exertion. In addition, there was a 39% gain in handgrip strength and a reduction in the execution time in the functional capacity tests. Heart rate variability after interventions showed that WBV can reduce cardiovascular risk. In conclusion, the exercise program allowed the reduction of body weight and body mass index and impacted the alteration of body composition and functionality, resulting in a reduction in cardiovascular risk.
