Peak basal rotation significantly increased after training, with changes in the endurance group (-2.2 ± 1.9° to -4.5 ± 3.3°) and the resistance group (-2.9 ± 3.0° to -3.4 ± 2.9°), while global peak strain data showed no change.

Why the study?

Little work had examined changes in left ventricular mechanics following exercise training using new regional and global indexes.

Does 24 weeks of supervised endurance versus resistance exercise training alter left ventricular mechanics in healthy untrained men?

Comparison

24-wk endurance training vs 24-wk resistance training

Design

Randomized trial

Follow-up

24 wk

Authors

DODavid Oxborough ASAngela L. Spence KGKeith George

Discussion

Member takes

Overview

Supervised endurance or resistance training increases basal rotation without altering most LV strain indices in healthy men; extends understanding of physiological cardiac adaptations to exercise.

Structured PICO

Does 24 weeks of supervised endurance versus resistance exercise training alter left ventricular mechanics in healthy untrained men?

Population

23 healthy untrained male subjects

Intervention

24-week supervised endurance exercise training program

Comparator

24-week supervised resistance exercise training program

Outcome

Left ventricular mechanics including global left ventricular strain in longitudinal, circumferential, and radial planes, and rotation at apical and basal levelssurrogate

24 weeks of intense supervised exercise training (endurance or resistance) increases basal rotation but does not significantly alter most global and regional indexes of LV mechanics in healthy untrained men.

Limitations

Small sample size
Lack of subjects with cardiovascular disease and risk factors
