Why the study?
Does moderate intensity supine exercise alter cardiac volumes and pumping mechanisms in healthy volunteers?
Population
26 healthy volunteers (6 women), mean age 30±8 years (range 19-59), with no signs of cardiac disease.
Comparison
Moderate intensity supine exercise using… vs Resting state.

Key result
Moderate intensity supine exercise in healthy volunteers decreased total heart volume by 4% and increased total heart volume variation from 5.9% to 9.7%.

Absolute Event Rate: 9.7% vs 5.9%
p-value: p=<0.001
Moderate intensity supine exercise decreases total heart volume due to reduced right ventricular volume, while increasing radial pumping contribution to stroke volume.
Steding‐Ehrenborg et al. (2013) conducted an observational in Healthy volunteers (n=26). Moderate intensity supine exercise vs. Rest was evaluated on Total heart volume variation (THVV) (p=<0.001). Moderate intensity supine exercise in healthy volunteers decreased total heart volume by 4% and increased total heart volume variation from 5.9% to 9.7%.
