Key result
Low-intensity exercise in water increased ventilation output and natriuretic peptides compared to land exercise, while hemodynamic changes were similar.
Why the study?
Does low-intensity exercise performed in water alter cardiorespiratory parameters compared to the same exercise performed on land in healthy subjects?

May warrant caution in aquatic prescriptions for cardiorespiratory patients; leaves open clinical relevance pending prospective trials.
Does low-intensity exercise performed in water alter cardiorespiratory parameters compared to the same exercise performed on land in healthy subjects?
Low-intensity exercise in water increases ventilatory work and facilitates fluid transfer to the interstitial sector compared to land exercise, without significant hemodynamic differences.
Ayme et al. (2014) studied Healthy (n=16). Low-intensity exercise in water vs. Low-intensity exercise on land was evaluated on Cardiorespiratory alterations (hemodynamic changes, gas exchanges, and biological changes). Low-intensity exercise in water increased ventilation output and natriuretic peptides compared to land exercise, while hemodynamic changes were similar.
