*4.2. Resting Heart Rate*

Resting heart rates (RHR) in the two analyzed intervals for Subject 4 are shown in Figure 5.

In our study, we observed that all participants in the study had a lower resting heart rate during self-isolation compared to the time before sheltering (−4.81%; −3.04; 95% CI, 2.59 to 3.51) which is shown in Figure 6. Interestingly, we found that the more active participants experienced a more significant decrease in their resting heart rate (Figure 7). However, we observed greater variability in resting heart rate in the elderly (Figure 8).
