Key result
A 30-minute multicomponent exercise session significantly increased circulating endothelial progenitor cells compared to a 45-minute session (difference 3.0%; 95% CI 1.3 to 4.7).
Why the study?
Although a dose-dependent relation between exercise training and vascular health has been suggested, little is known regarding the effects of different exercise durations on endothelial markers.
Does a 30-minute multicomponent exercise session improve circulating levels of endothelial progenitor cells compared to a 45-minute session in adults with cardiovascular risk factors?
Does a 30-minute multicomponent exercise session improve circulating levels of endothelial progenitor cells compared to a 45-minute session in adults with cardiovascular risk factors?
A 30-minute multicomponent exercise session acutely increases circulating endothelial progenitor cells without increasing endothelial damage compared to a 45-minute session in adults with cardiovascular risk factors.
Shorter sessions may enhance EPC mobilization; leaves open optimal exercise duration for vascular benefits in clinical populations.
It is widely accepted that exercise training has beneficial effects on vascular health. Although a dose-dependent relation has been suggested, little is known about the effects of different exercise durations on endothelial markers. This study aimed to assess the effect of single exercise sessions with different durations in the circulating levels of endothelial progenitor cells (EPCs) and endothelial cells (CECs) among adults with cardiovascular risk factors. Ten participants performed two multicomponent exercise sessions, one week apart, lasting 30 and 45 min (main exercise phase). Before and after each exercise session, blood samples were collected to quantify EPCs and CECs by flow cytometry. The change in EPCs was significantly different between sessions by 3.0% (95% CI: 1.3 to 4.7), being increased by 1.8 ± 1.7% (p = 0.009) in the 30 min session vs. −1.2 ± 2.0% (p > 0.05) in the 45 min session. No significant change was observed in CECs [−2.0%, 95%CI: (−4.1 to 0.2)] between the sessions. In conclusion, a multicomponent exercise session of 30 min promotes an acute increase in the circulating levels of EPCs without increasing endothelial damage (measured by the levels of CECs) among adults with cardiovascular risk factors.

Cavalcante et al. (2022) studied Cardiovascular risk factors (n=10). Multicomponent exercise session vs. 45 min multicomponent exercise session was evaluated on Change in circulating levels of endothelial progenitor cells (EPCs) (MD 3.0%, 95% CI 1.3 to 4.7). A 30-minute multicomponent exercise session significantly increased circulating endothelial progenitor cells compared to a 45-minute session (difference 3.0%; 95% CI 1.3 to 4.7).
