Key result
The acute increases in arterial stiffness and peripheral and central blood pressure following a maximal running exercise were independent of the subjects' aerobic training status (p > 0.05 for all Δ comparisons).
Why the study?
Does the acute hemodynamic response (blood pressure and arterial stiffness) to a maximal running exercise depend on the aerobic training status of healthy young subjects?

Acute increases in arterial stiffness and blood pressure following maximal running are independent of aerobic training status in healthy young adults, suggesting high-intensity running is a suitable training mode for both groups.
Acute responses to maximal running appear independent of training status; hypothesis-generating and should not yet change practice.
Background: High-intensity training has become increasingly popular in recent years but the exact effects of high intensity running on the hemodynamic system are not entirely understood and it is unknown whether the aerobic training status of the subjects might influence these hemodynamic reactions.Therefore, the study aims to evaluate whether the acute reactions of peripheral and central blood pressure (BP) and arterial stiffness (AS) to a maximal running exercise depend the training status of the subjects.Methods: 41 healthy subjects were recruited.Of these were 21 aerobically trained (AE; 11 men) and 20 untrained (UN; 10 men).Aortic pulse wave velocity (PWV), peripheral and central BP was measured at rest and immediately after a maximal treadmill exercise using a ramp protocol including spirometric measurements.Results: Resting hemodynamic values were not different between the groups.Systolic central and peripheral BP, and PWV increased in both groups in response to the running exercise.D of all measured parameters showed no difference between the groups.Conclusions: The acute increases of AS and BP to a maximal running regimen seem to be independent of the subjects' training status and might therefore be an eligible training mode to maintain overall and vascular health.

Tomschi et al. (2018) conducted a cross-sectional in Healthy (n=41). Aerobic training status vs. Untrained status was evaluated on Difference in acute changes (Δ) of peripheral/central blood pressure and pulse wave velocity after maximal running exercise between trained and untrained subjects (p=>0.05). The acute increases in arterial stiffness and peripheral and central blood pressure following a maximal running exercise were independent of the subjects' aerobic training status (p > 0.05 for all Δ comparisons).
