“…To some extent, the results indicate that the reduction of ST among those who participate in less than 300 min of MVPA per week. Notably, the present study highlights the negative effects of prolonged ST on abnormal HRR, but it has also been shown that regular breaks in prolonged ST can mitigate its potentially harmful effects [39]. This statement implies that we need to not only focus on reducing the total time spent sitting, but also encourage people to interrupt prolonged periods of sitting with PA.…”

“…In this regard, it is known that an abnormal HRR is an independent risk factor for cardiovascular events [4,5,36]. Several large-scale population-based studies have investigated the joint association of ST and PA with other cardiovascular predictors, including maximal oxygen uptake, blood glucose, and triglyceride levels [37][38][39][40]. Nayor et al [37] verified that adults with HST (≥ 821 min/day) and low VPA had the lowest levels of maximal oxygen uptake, and those with HST and high VPA had above-average maximal oxygen uptake.…”

“…Still, independent of PA amounts, higher TV viewing time in adults was associated with higher values of adipose tissue. Furthermore, Alansare et al [39], using an isotemporal substitution model, found that replacing sedentary time with 30 min of MVPA was a potential strategy for improving cardiac autonomic function as measured by heart rate variability in young and middleaged women. The same research group [40] also showed a significant negative association between sedentary leisure time and heart rate variability by stratified analysis in a population of young and middle-aged women who did not meet the recommended leisure time for MVPA.…”

Background Abnormal heart rate recovery (HRR), representing cardiac autonomic dysfunction, is an important predictor of cardiovascular disease. Prolonged sedentary time (ST) is associated with a slower HRR. However, it is not clear how much moderate-to-vigorous physical activity (MVPA) is required to mitigate the adverse effects of sedentary behavior on HRR in young and middle-aged adults. This study aimed to examine the joint association of ST and MVPA with abnormal HRR in this population. Methods A cross-sectional analysis was conducted on 1253 participants (aged 20–50 years, 67.8% male) from an observational study assessing cardiopulmonary fitness in Fujian Province, China. HRR measured via cardiopulmonary exercise tests on a treadmill was calculated as the difference between heart rate at peak exercise and 2 min after exercise. When the HRR was ≤ 42 beats·minute−1 within this time, it was considered abnormal. ST and MVPA were assessed by the IPAQ-LF. Individuals were classified as having a low sedentary time (LST [< 6 h·day−1]) or high sedentary time (HST [≥ 6 h·day−1]) and according to their MVPA level (low MVPA [0–149 min·week−1], medium MVPA [150–299 min·week−1], high MVPA [≥ 300 min·week−1]). Finally, six ST-MVPA groups were derived. Associations between ST-MVPA groups with abnormal HRR incidence were examined using logistic regression models. Results 53.1% of the young and middle-aged adults had less than 300 min of MVPA per week. In model 2, adjusted for possible confounders (e.g. age, sex, current smoking status, current alcohol consumption, sleep status, body mass index), HST was associated with higher odds of an abnormal HRR compared to LST (odds ratio (OR) = 1.473, 95% confidence interval (CI) = 1.172–1.852). Compared with the reference group (HST and low MVPA), the HST and high MVPA groups have a lower chance of abnormal HRR (OR, 95% CI = 0.553, 0.385–0.795). Compared with individuals with HST and low MVPA, regardless of whether MVPA is low, medium, or high, the odds of abnormal HRR in individuals with LST is significantly reduced (OR, 95% CI = 0.515, 0.308–0.857 for LST and low MVPA; OR, 95% CI = 0.558, 0.345–0.902 for LST and medium MVPA; OR, 95% CI = 0.476, 0.326–0.668 for LST and high MVPA). Conclusion Higher amounts of MVPA appears to mitigate the increased odds of an abnormal HRR associated with HST for healthy young and middle-aged adults.
