The RCV blood flow velocity has increased significantly from the resting baseline at 6 min of exercise in both thermal conditions, whereas the STRA and SNRA blood flows had not changed significantly in either condition at this time point (Figure 1 and 2).
The STRA and SNRA blood flows decreased significantly from the resting baseline value only in the heat condition.
16 min in the heat condition vs 24 min in the control condition), revealed that the SNRA blood flow differed significantly between the two conditions, whereas the CI in the SNRA did not.
At recovery, the blood flow velocity in the RCV and blood flows in the STRA and SNRA were significantly lower than at baseline in both thermal conditions.
In the heat condition, the ratio of change in RCV blood flow velocity to that in MAP was greater than that for SNRA during exercise (p < 0.
The blood flow velocity in the RCV increased from the resting baseline at 6 min of exercise in both conditions, whereas blood flows in the STRA and SNRA did not change.
