Key result
Repeated prior breath-holds increase facial immersion breath-hold duration by up to ~43% vs control.
Why the study?
The cardiorespiratory and haematological responses to various non-maximal breath-hold techniques used to improve breath-hold duration were not well characterized.
Do non-maximal breath-hold techniques improve breath-hold duration and alter cardiorespiratory responses during facial immersion in healthy men?
RCT (n=10)
randomized
Do non-maximal breath-hold techniques improve breath-hold duration and alter cardiorespiratory responses during facial immersion in healthy men?
p-value: p=<0.001
Non-maximal breath-hold techniques extend subsequent breath-hold duration by manipulating blood gases, without requiring changes in cardiac output or red blood cell mass.

BHTs may alter responses in healthy men; leaves open any clinical translation or performance benefit.
Burley et al. (2022) conducted an RCT in Healthy (n=10). Breath-hold techniques (BHTs) vs. Quiet rest was evaluated on Breath-hold duration during facial immersion (p=<0.001). Breath-hold techniques involving repeated prior breath-holds increased facial immersion breath-hold duration by 30.8–43.3% compared with control (P<0.001).
