Treatment-related correlations across conditions.

Correlations	Control	Beetroot juice
MCAV versus MABP	+0.13 (NS)	+0.21 (NS)
MCAV versus CO	+0.45*	+0.46*
MCAV versus TVR	−0.52**	+0.43*
MCAV versus CVRI	−0.89**	−0.89**

MCAV: middle cerebral arterial blood flow velocity; MABP: mean arterial blood pressure; CO: cardiac output; TVR: total vascular (peripheral) resistance; CVRI: cerebral vascular resistance index.
Values are Pearson’s product-moment correlation coefficients computed across baseline rest and three submaximal aerobic exercise conditions.
NS: not statistically significant.
*Significant at 𝑃<0.01, **significant at 𝑃<0.001, 46 df.
