Effects of exercise on obesity and depression: an review
Abstract
Introduction: Obesity can contribute to the manifestation of psychological disorders such as anxiety and depression. As well as, depressive people are extremely susceptible to excessive weight gain and duplicate prevalence of obesity. In this context, physical exercise plays an important role in improving physical and psychological health. Objective: To integrate the scientific findings about the effects of physical exercise programs on obesity and depression. Methods: A survey was conducted of the electronic databases Medline, Lilacs and PubMed, with the keywords: obesity and exercise or physical activity and depression. Clinical trial, intervention, quasi-experimental and cohort studies of the last eight years were selected and were available in full. Results: The measured studies presented samples ranging from 12 to 66 years old, covering both sexes. They used different intervention programs, with predominance of aerobic exercises. The duration of the exercises ranged from three to eight months. The weekly application frequency varied from one to five times a week and the duration of the sessions was around 45 minutes. Most of the studies showed positive effects of physical exercise on depression, anxiety symptoms and weight loss after the interventions. Conclusion: The results showed that the practice of physical exercises positively influences the mental and physical health of obese people, since it reduces the picture of depression and, in most cases, leads to a decrease in body mass index and waist circumference.
