Key result
Resistance exercise combined with KAATSU during simulated weightlessness significantly decreased stroke volume to 55.9 ml compared to 77.0 ml with exercise alone, mimicking gravity-specific stress.
Why the study?
Does resistance exercise combined with KAATSU alter hemodynamic and neurohumoral responses compared to resistance exercise alone in healthy males during simulated weightlessness?

Absolute Event Rate: 55.9% vs 77%
p-value: p=<0.01
KAATSU combined with resistance exercise during simulated weightlessness induces hemodynamic and neurohumoral responses similar to gravity-specific stress, suggesting it may be a useful countermeasure for cardiovascular deconditioning in space flight.
Kubota et al. (2008) conducted an RCT in Simulated weightlessness (cardiovascular deconditioning) (n=7). Resistance exercise combined with KAATSU vs. Resistance exercise without KAATSU was evaluated on Stroke volume at peak exercise (p=<0.01). Resistance exercise combined with KAATSU during simulated weightlessness significantly decreased stroke volume to 55.9 ml compared to 77.0 ml with exercise alone, mimicking gravity-specific stress.
