RVEDV and RVESV decreased during exercise in endurance-trained individuals but were unchanged in untrained individuals, while RAVmax decreased in endurance-trained but remained unchanged in untrained individuals.

Why the study?

Does endurance training alter the dynamic right ventricular and atrial volume responses to exercise in healthy individuals?

Population

33 healthy individuals (20 endurance-trained [9 women] and 13 untrained matched for age and sex)

Comparison

Moderate and vigorous exercise evaluated by… vs Untrained healthy individuals and resting state

Design

Cross-sectional

Authors

BÖBjörn Östenson EOEllen Ostenfeld JEJonathan Edlund

Discussion

Overview

LV volumes decrease during exercise regardless of training status; extends simultaneous four-chamber assessment but leaves open clinical translation.

Structured PICO

Does endurance training alter the dynamic right ventricular and atrial volume responses to exercise in healthy individuals?

Population

33 healthy individuals (20 endurance-trained [9 women] and 13 untrained matched for age and sex)

Intervention

Moderate and vigorous exercise evaluated by real-time cardiac magnetic resonance imaging (CMR)

Comparator

Untrained healthy individuals (for group comparison) and resting state (for exercise comparison)

Outcome

Volume responses of the four cardiac chambers (LV and RV end-diastolic and end-systolic volumes, stroke volumes, and maximal/minimal LA and RA volumes) measured at end expirationsurrogate

Endurance-trained individuals exhibit distinct right ventricular and right atrial volume reductions during exercise compared to untrained individuals, highlighting specific right-sided cardiac adaptations to training.
