The COVID-19 pandemic has had cardiorespiratory, musculoskeletal and life habits repercussions, such as sleep and physical activity, both in the acute phase and after the disease. Thus, it is important to identify these changes in these patients to structure prevention and rehabilitation measures in clinical practice.

To profile sleep parameters and physical activity level in post-COVID-19 patients.

This is a cross-sectional study, carried out from November 2022 to March 2023, at the Cardiopulmonary Rehabilitation Laboratory of the Physiotherapy Department of the Federal University of Pernambuco. Patients aged 18 and over, of both sexes, with a diagnosis of COVID-19 confirmed through a positive result in molecular and serological tests between 3-12 months of diagnosis were included. And excluded, patients who make use of sleep-inducing medication, who have cardiometabolic diseases such as grade III obesity, as well as decompensated chronic degenerative diseases, neuromuscular or some cognitive impairment that makes it difficult to understand how the evaluations will be carried out and who have osteopathies -joints that make it impossible to perform during the physical assessment protocol. Sleep efficiency, total sleep time, number of awakenings and sleep latency were evaluated using actigraphy and the Pittsburg Sleep Quality Index (PSQI), in addition to sleep quality. The level of physical activity was also assessed using the International Physical Activity Questionnaire - IPAQ. The descriptive analysis of the data was presented as mean and standard deviation.

Eighteen patients were selected, predominantly female (74.3%), aged 46.4 ± 12.9 years. On the actigraphy data, a total sleep time of 8.0 ± 5.6 hours was verified, the sleep efficiency was 75.3 ± 10.0%, the number of awakenings was 7.5 ± 4, 9 times and a sleep latency of 4.5 ± 2.9 minutes. The PSQI showed poor sleep quality with an average of 6.4 ± 3.2 points. In addition, a total sleep time of 9 ± 4.6 hours, sleep efficiency of 68.3 ± 7.6%, number of awakenings of 4.2 ± 2.8 times and sleep latency of 6 .5 ± 2.8 minutes. Regarding the level of physical activity, it was observed that 50.3% of the sample was insufficiently active, 23.4% active and 26.3% sedentary.

The results showed poor sleep quality by PSQI, moderate sleep efficiency, lower sleep latency and good total sleep time. Regarding the level of physical activity, it was demonstrated that most of these patients were insufficiently active.

Identifying these changes in these patients will imply the structuring of measures to prevent further complications of the disease and rehabilitation of these repercussions in clinical practice.
