Associated scholarship(s):19/07150-4 - Breaking up sedentary time in rheumatoid arthritis: effects on vascular function, BE.EP.PD


This postdoctoral is a joint venture between the candidate's PhD research line (FAPESP 2013/05519-4) - i.e. the study of the effects of exercise in the cardiovascular autonomic function in cardiovascular diseases - and the Laboratory of Assessment and Conditioning in Rheumatology of the Rheumatology Division of the General Hospital of the University of Sao Paulo. Since some recent studies have suggested that autonomic dysfunction is an important complication of Rheumatoid Arthritis (RA), and given that a large time in sedentary activities could be a trigger for this dysfunction, in this specific project the student will investigate: (1) the cardiovascular autonomic dysfunction in patients with RA; (2) the relationship between autonomic dysfunction and inflammation and; (3) the effects of breaks in sedentary time in that dysfunction. For this purpose, 30 women with RA will perform: (1) clinical tests; (2) physical activity and fitness assessments; (3) pro-inflammatory cytokines profile and; (4) cardiovascular autonomic assessment. Additionally, 15 healthy women will form a healthy control group (HCG) to perform the cardiovascular autonomic assessment. After the pre-intervention measurements, patients with RA will be divided into 2 groups: 1) breaks in sedentary time (BST) and 2) control group (CG). The intervention period will be of 4 months. During this period, the BST group will be instructed to follow goals aiming to reduce sedentary time. These goals will be composed by 5 categories: leisure, work, transport, social activities and meals; and each goal will have an upgrade at 2 months of intervention. At the end of the intervention period, participants from both groups will perform the same pre-intervention measurements. The Student T test will be performed for comparisons of the cardiovascular autonomic function between healthy and RA women. A mixed model analysis for repeated measurements will be performed to investigate the effects of the intervention in the cardiovascular autonomic function of the BST and CG groups. When pertinent, Tukey post-hoc will be used for multiple comparisons. (AU)
