A sedentary lifestyle is a major public health problem because it increases the risks of Type II diabetes, obesity, and metabolic diseases. Office workers are usually characterized by sedentary behavior due to the restricted and sustained posture adopted in the seated position, especially during the use of the computer. However, there is still a limitation of evidence on the impact of this behavior at work. In addition, little has been investigated about the level of physical activity outside work and whether there is any relationship between the level of physical activity at work and outside it. Thus, the present study aims to evaluate the level of physical activity of office workers and characterize the musculoskeletal signs/symptoms and functionality of the upper limbs and spine. To that end, a sample of 30 administrative workers divided proportionally (Group A n = 15 BMI d 25; Group B n = 15 BMI> 25 and <34.9 kg / m²), who use the computer as their main working tool for at least 5 years, will be evaluated by means of accelerometers for five consecutive days, two days of leisure and three days of work. Signs and symptoms will be evaluated through the Nordic Musculoskeletal Questionnaire, and the functionality of the upper limbs and spine through the Disabilities of the Arm, Shoulder, and Hand (DASH) and the Roland-Morris Disability Questionnaire, respectively. A descriptive analysis of the data will be performed to characterize the demographic data of the population. The two-way mixed-use ANOVA will be applied to verify if there is a difference between the level of physical activity during work and leisure (within-subjects) and between groups (between-subjects). The data will also be treated using Spearman's Simple Linear Regression and Correlation Coefficient. The significance level of 5% will be adopted. With this study, we intend to contribute to a better understanding of the level of physical activity at work and outside the work of the studied population, as well as to better characterize the presence of musculoskeletal signs and symptoms, which may guide future studies or preventive intervention strategies.
