urpose: To assess the associations between physical activity (PA) and sedentary time (SEDT) with inflammatory and oxidative stress markers, heart rate variability (HRV) and post-exercise recovery (HRR) controlling for cardiorespiratory fitness (CRF) and potential confounders. Methods: The following data was collected from 44 participants [66% women, age=49.56.4 years, BMI=28.16.2 kg·m-2,]: Plasma levels of C-reactive protein (CRP), and cytokines (IL-1β, INF-γ, TNF-α, MCP-1, IL-6, IL-8, IL-10, IL-18, IL-23); plasma catalase (CAT) and glutathione peroxidase (GPX) activities; resting heart (HR) rate for HRV analysis (time and frequency domains, non-linear, PNS and SNS Index), anthropometric measures, a submaximal cycling test to evaluate CRF with active recovery to assess and HRR (kinetics, absolute and ΔHR), and 7-day PA monitoring by accelerometry.Results: Compared to men, women spent more SEDT (P=0.035, ES=0.72), with less sedentary breaks (P=0.014,
