Comparação do efeito de diferentes intervenções de exercício nos níveis de atividade física em doentes submetidos a Cirurgia Bariátrica

Abstract

In recent decades, obesity has become a serious public health problem, affecting a large and growing number of patients of different age groups (Jones et al., 2012). Due to the absence of adequate treatment strategies and the growing number of patients with severe obesity, bariatric surgery has gained, particularly in the last two decades, an enormous preponderance in the treatment of patients with severe obesity, allowing excess weight loss of up to 70% to be achieved (O'Brien, 2000). However, despite the high success rates, there is still a percentage between 5% and 20% of patients who regain weight significantly after bariatric surgery (Heymsfield & Wadden, 2017). To increase the success of bariatric surgery in reducing excess weight and mitigating comorbidities associated with obesity, it is recommended that patients adhere to a physically active lifestyle by increasing daily physical activity and regular participation in structured physical exercise. However, there is no adequate evidence in the literature regarding the potential effect that the performance of different types of exercise may have on the levels of daily physical activity of these patients. The aim of the present study was to compare the effect of two different types of training, one based on endurance exercise and the other on resistance exercise, on the levels of daily physical activity of patients with obesity who had previously undergone bariatric surgery. To this end, a randomized clinical trial was carried out with two groups lasting 16 weeks in which each group performed 3 weekly training sessions, lasting 1 hour. Immediately before and after the intervention, the number of daily steps and the estimated daily energy expenditure were evaluated. The results suggest that there is no statistically significant distinct effect of the two types of training on the daily physical activity levels of patients previously undergoing bariatric surgery.
