Efetividade de estratégias tecnológicas para aumentar o nível de atividade física e reduzir o comportmento sedentário de trabalhadores administrativos

Abstract

The aim of this dissertation was to verify the feasibility and effectiveness of a remote intervention using technological strategies based on the Social Cognitive Theory to change the level of physical activity and reduce sedentary behavior in administrative servers at a university. A quasi-experimental study was carried out in a sample composed of 30 administrative workers from the Federal University of Triângulo Mineiro. The intervention called the LEV Program – “Get Up, Move, Live” had three evaluation periods (PRE, MEDIUM and POST). Employees were assessed for their level of physical activity, sedentary behavior, self-efficacy, and perceived barriers to physical activity. Most participants were women (90%), aged 42±1.48 years and BMI of 25.7±0.86 kg/m². The results indicated that despite the improvement in the level of physical activity self-reported by the IPAQ (p=0.001), the intervention was not able to increase the level of physical activity (p=0.16) and reduce sedentary behavior (p=0. 09) measured by accelerometry. However, during the intervention there was an increase in the perception of barriers to physical activity (2.7 to 3.5, p=0.001). Therefore, the results show that, in addition to encouraging the practice of physical activity and reducing sedentary behavior in the work environment, it is necessary to evaluate ways to reduce the perceived barriers to the practice of physical activity in this population.
