Key result
Sedentary time shows no clinically meaningful association with resting HR or HRV.
Why the study?
To evaluate whether sedentary time is associated with heart rate and heart rate variability in adults.
Does sedentary time affect resting heart rate and heart rate variability in adults?
Meta-Analysis
Does sedentary time affect resting heart rate and heart rate variability in adults?
Sedentary time is associated with an unfavorable but not clinically meaningful increase in resting heart rate, with no significant impact on heart rate variability.
Answers are grounded in this paper and cite their sources.
Sedentary time shows no clinically meaningful link to heart rate or variability; leaves open whether reducing sitting time improves autonomic function in trials.
PURPOSE: To evaluate if sedentary time (ST) is associated with heart rate (HR) and variability (HRV) in adults. METHODS: We systematically searched PubMed and Google Scholar through June 2020. Inclusion criteria were observational design, humans, adults, English language, ST as the exposure, resting HR/HRV as the outcome, and (meta-analysis only) availability of the quantitative association with variability. After qualitative synthesis, meta-analysis used inverse variance heterogeneity models to estimate pooled associations. Substantial heterogeneity was detected. CONCLUSIONS: The limited available evidence suggests an unfavorable but not clinically meaningful association between ST and HR, but no association with HRV. Future longitudinal studies assessing ST with thigh-based monitoring and HRV with electrocardiogram are needed.

Alansare et al. (2021) reported a meta-analysis. Sedentary time was evaluated on Resting heart rate and heart rate variability (p=> 0.05). Sedentary time has an unfavorable but not clinically meaningful association with heart rate, and no association with heart rate variability (P>0.05).
