Following 12 months of endurance training, significant decreases were observed in LV longitudinal (26.0 ± 3.3% vs. 24.3 ± 3.2%, P < 0.04), circumferential (24.3 ± 4.3% vs. 20.1 ± 3.8%, P < 0.002), and RV systolic strain (28.1 ± 6.7% vs. 23.7 ± 8.6%, P < 0.03), while LV base rotation increased (-3.9 ± 2.8% vs. -5.9 ± 1.8 deg, P < 0.01).

Why the study?

Does high-intensity endurance exercise training alter left and right ventricular mechanics in previously untrained subjects?

Population

21 previously untrained amateur subjects preparing for triathlon competitions, aged 33 ± 6 years.

Comparison

High-intensity endurance exercise training for… vs Baseline (before training).

Design

Cohort

Follow-up

12 months

Authors

ARAleksandra Rojek DBDariusz Biały MPMonika Przewłocka‐Kosmala

Discussion

Member takes

Overview

Endurance training-associated ventricular strain reductions warrant caution in athlete strain interpretation; leaves open whether adaptive or clinically relevant.

Structured PICO

Does high-intensity endurance exercise training alter left and right ventricular mechanics in previously untrained subjects?

Population

21 previously untrained amateur subjects preparing for triathlon competitions, aged 33 ± 6 years.

Intervention

High-intensity (12.3 ± 1.0 h/week) endurance exercise training (EET) for 12 months.

Comparator

Baseline (before training).

Outcome

Left (LV) and right ventricular (RV) mechanics assessed by conventional and speckle tracking echocardiography at rest.surrogate

High-intensity endurance exercise training in previously untrained subjects leads to significant alterations in resting LV and RV mechanics, including reduced apical contractility and increased basal rotation, which may represent a protective mechanism to reduce myocardial stress.
