Key result
Elite breath-hold divers exhibited a significantly lower slope of pulmonary ventilation to carbon dioxide elimination (18.4 vs 21.6, P < .01) during exercise compared to matched controls.
Why the study?
Does elite breath-hold diving alter ventilatory response characteristics and blood lactate concentrations during dynamic exercise compared to scuba diving or no diving?

May indicate training-related ventilatory adaptations in breath-hold divers; hypothesis-generating and requires prospective confirmation before clinical relevance.

Does elite breath-hold diving alter ventilatory response characteristics and blood lactate concentrations during dynamic exercise compared to scuba diving or no diving?
Absolute Event Rate: 18.4% vs 21.6%
p-value: p=<0.01
Elite breath-hold divers exhibit a distinct ventilatory-response pattern and signs of a metabolic shift from aerobic to anaerobic energy supply during dynamic exercise.
Röecker et al. (2014) conducted a case-control in Healthy (n=24). Elite breath-hold diving vs. Scuba divers and matched controls was evaluated on Slope of Δ pulmonary ventilation to Δ VCO2 (p=<0.01). Elite breath-hold divers exhibited a significantly lower slope of pulmonary ventilation to carbon dioxide elimination (18.4 vs 21.6, P < .01) during exercise compared to matched controls.
