Sleep plays an important role over numerous biological functions, and it is essential that factors such as its duration and quality are adequate for a perfect regulation of the circadian cycle. It is known that when these factors are affected, they promote negative health consequences, leading to the emergence of some diseases, such as obesity, diabetes, heart disease, dementia and depression. Within this context, a sedentary lifestyle has a strong influence on quality of life, especially sleep and aspects related to health indicators such as the lipid profile. In this sense, several authors have reported that some professional activities, such as military police, have a long working day, which is associated with high levels of stress, physical inactivity and poor diet, thus compromising the quality of sleep and predisposing for the emergence of chronic degenerative diseases. The objective of this research project will be to assess the quality of sleep, the level of physical activity and the health indicators of military police officers in the administrative sector, who work from 9 am to 6 pm and in the 190 sector, who work in the 12 pm shift and rest 24h. In total, "Administrative Police Officers" (N = 88) and "Operational Police Officers - Program 190" (N = 100) will be evaluated. These will later be divided into four groups: 1- (GPAI-n = 44) - administrative police-unfit for physical condition, 2- (GPAB-n = 44) - administrative police- with good physical condition and 3- (GP190I - n = 50) police officers who work on the street - unfit for physical condition, 4- (GP190B - n = 50) police officers who work on the street - with good physical condition. The result of the physical fitness test (TAF 3) will be used, which will be available in the medical records of the participants to classify the physical condition of the participants. The sample composition was obtained through the sample calculation using the online tool 'Survey Monkey®'. The following statistical parameters were considered: the 95% confidence level (z = 1.96), the maximum statistical error of 5.0% and the size of the population to be surveyed. In this research will be evaluated: level of physical activity and sleep (Bodyguard 2, Firstbeat®) and anthropometric measures (body mass, height, body mass index, waist circumference and fat percentage) and biochemical indicators present in medical records (lipid profile , glucose, complete blood count, TGO (Glutamic-Pyruvic Transaminase), TGP (Glutamic-Oxalacetic Transaminase) and Creatinine, as well as the anamnesis regarding the history of diseases and use of medications. the different work routines on the health conditions of military police officers and from there propose non-pharmacological strategies such as physical exercise and nutrition to promote the health of the participants.
