Key result
Voluntary one-armed cranking increased oxygenation in the right dorsolateral and ventrolateral prefrontal cortices in a feedforward- and motor effort-dependent manner (P<0.05).
Observational (n=20)
p-value: p=<0.05
The dorsolateral and ventrolateral prefrontal cortices on the right side show increased oxygenation in a feedforward- and motor effort-dependent manner during voluntary exercise, suggesting a role in triggering central command for cardiovascular regulation.
No takes yet. Share an insight, caveat, or question.
No immediate clinical implications; leaves open prefrontal contributions to central command in cardiovascular models.
Ishii et al. (2018) reported an observational. Voluntary one-armed cranking vs. Motor-driven passive one-armed cranking was evaluated on Oxygenation responses in the frontal and frontoparietal areas (p=<0.05). Voluntary one-armed cranking increased oxygenation in the right dorsolateral and ventrolateral prefrontal cortices in a feedforward- and motor effort-dependent manner (P<0.05).
