Key result
Isometric handgrip exercise increased myocardial work and slightly reduced global longitudinal strain without altering left ventricular ejection fraction.
Why the study?
Does isometric handgrip exercise alter left ventricular mechanics assessed by myocardial work in healthy adults?
Does isometric handgrip exercise alter left ventricular mechanics assessed by myocardial work in healthy adults?
Myocardial work assessment during isometric handgrip exercise provides a sensitive method to detect subtle physiological adaptations in left ventricular mechanics beyond ejection fraction.

Barretto et al. (2026) conducted an editorial in Healthy adults. Isometric handgrip exercise vs. Rest was evaluated on Left ventricular mechanics (Global Longitudinal Strain and Myocardial Work). Isometric handgrip exercise increased myocardial work and slightly reduced global longitudinal strain without altering left ventricular ejection fraction.
