Why the study?

Does 16 weeks of intensive training induce morphological and functional changes in the left and right atria of top-level female athletes?

Key Points

To determine whether intensive exercise training induces left and right atrial morphological and functional remodeling in top-level female athletes.
Prospective longitudinal study evaluating 24 top-level female athletes before the season and after 16 weeks of intensive training.
Two-dimensional and speckle-tracking echocardiography were used to quantify biatrial volumes, myocardial deformation, filling pressures, and atrial stiffness.
Left atrial volume index increased from 24.0±3.6 to 26.7±6.9 mL/m² (P<0.001) and right atrial volume index increased from 15.66±3.09 to 20.47±4.82 mL/m² (P<0.001) post-training.
Left atrial global peak atrial longitudinal strain decreased from 43.9±9.5% to 39.8±6.5% (P<0.05) and peak atrial contraction strain decreased from 15.5±4.0% to 13.9±4.0% (P<0.05), alongside non-significant decreases in right atrial strains.
Biventricular E/e' ratio and biatrial stiffness remained unchanged following the 16-week training period.

Does 16 weeks of intensive training induce morphological and functional changes in the left and right atria of top-level female athletes?

Population

24 top-level female athletes

Intervention

16 weeks of intensive training

Comparator

Baseline (before season)

Outcome

Left and right atrial morphology and function assessed by two-dimensional echocardiography and speckle-trackingsurrogate

Intensive training in female athletes induces physiological biatrial enlargement with normal filling pressures, which should be differentiated from cardiomyopathies.

Discussion

No takes yet. Share an insight, caveat, or question.

Implication

May support physiological biatrial adaptation in elite female athletes; extends male-centric data but leaves causal and clinical differentiation open.
