The Claim
Right ventricular atrio-ventricular plane displacement is 15% greater in female endurance athletes compared to non-athletic controls, with measured values of 21 mm versus 19 mm, and this difference remains statistically significant after adjustment for left ventricular length.
What the research says
Supports is higher
Support is ahead, but a single strong opposing study can change this.
These are independent scores, not a percentage. Higher-grade studies count more, so a single strong opposing study can outweigh several weaker ones.
Female endurance athletes have a 15% greater movement of the heart's lower right chamber during pumping compared to non-athletes, with measurements of 21 mm versus 19 mm, and this difference persists even when accounting for differences in the size of the left ventricle.
See the scientific wording
Right ventricular atrio-ventricular plane displacement is 15% greater in female endurance athletes than in non-athletic controls (21 mm vs. 19 mm), and this difference remains significant after indexing for left ventricular length, suggesting right ventricular adaptation to endurance training.
Endurance training increases the amount of blood returning to the heart during exercise, which stretches the right ventricle over time. This stretch causes the muscle to grow longer and more elastic without thickening, allowing it to move farther downward with each heartbeat. The heart also fills more efficiently during relaxation, pulling more blood into the right ventricle before it pumps. This combination lets the right ventricle push more blood through the lungs with each beat, increasing its movement by 15% compared to untrained individuals.
What the research says
1 studyStudy: Female athlete's heart: Systolic and diastolic function related to circulatory dimensions
Female athletes who train hard have a part of their right heart that moves more during each beat than non-athletes, even when you account for overall heart size — showing their hearts adapt to endurance training.
