Long COVID has been linked to a decline in physical activity and functional capacity. However, it remains unclear which physical symptoms are associated with specific aspects of movement behaviors and functional capacity. We aimed to investigate the associations of fatigue, dyspnea, post-exertional malaise, myalgia, and the co-occurrence of symptoms with movement behaviors and functional capacity in individuals with Long COVID. A cross-sectional multicenter study was conducted. Questionnaires were used to assess fatigue, dyspnea, post-exertional malaise, and myalgia. Accelerometry was employed to assess sedentary time, steps per day, light physical activity, and moderate-to-vigorous physical activity. The six-minute walk test, 30-s chair stand test, and timed up and go were used to assess functional capacity. One hundred and two community-dwelling individuals who had been living with Long COVID for 15 ± 10 months participated in the study. Fatigue, post-exertional malaise, and the co-occurrence of physical symptoms showed a negative association with step count, while post-exertional malaise was also negatively associated with moderate-to-vigorous physical activity. Dyspnea showed a negative association with the functional score, including all tests. Our findings suggest that fatigue, post-exertional malaise, and the co-occurrence of physical symptoms are negatively associated with physical activity, while dyspnea is negatively associated with functional capacity in individuals with Long COVID.

Purpose: The aim of this study was to investigate whether only 1 multi-joint resistance exercise involving large muscle groups can elicit post-exercise hypotension (PEH).Methods: A randomized crossover trial was conducted with 13 normotensive-trained women (21.8 ± 2.1 years; 23.5 ± 3.1 kg/m2; blood pressure 100.4 ± 4.9/58.6 ± 5.6 mmHg). They were submitted randomly into two sessions: (a) a single multi-joint resistance exercise session (3 sets of 20 repetitions at 80% of 20 repetitions maximum performed on double-leg press machine) and (b) control session (15 min of resting in a seated position). Blood pressure (BP) was measured before and at 20, 40, and 60 min following the control and resistance exercise sessions.Results: It was observed a reduction in systolic BP at 40 min (4.8 ± 4.6 mmHg) and 60 min (6.3 ± 4.3 mmHg) post-exercise with a moderate magnitude (d ≥ 0.79, p < 0.05). Moreover, 10 participants (i.e., 77% of the sample) decreased at least 3 mmHg of systolic BP post-exercise. There was no change in diastolic BP and mean BP post-exercise (p > 0.05).Conclusion: A single multi-joint high-intensity resistance exercise involving large muscle groups and performed within a very low time commitment elicited systolic PEH in normotensive-trained women.
