Why the study?
Does high-intensity interval training (HIIT) yield reproducible ambulatory blood pressure measurements in healthy normotensive men?
Does high-intensity interval training (HIIT) yield reproducible ambulatory blood pressure measurements in healthy normotensive men?
Ambulatory blood pressure monitoring after HIIT sessions shows good reproducibility during the awake period but not during the asleep period in healthy normotensive men.

Reproducibility of post-HIIT ambulatory BP in young normotensives should not yet change practice; leaves open validation in hypertensive cohorts.
This study analyzed the reproducibility of ambulatory blood pressure (BP) after high-intensity interval training (HIIT) sessions. Seventeen normotensive men (23.5±2.4 years) underwent two HIIT and two control sessions separated by 7-10 days. Ambulatory BP monitoring devices were used for 20 h. The intraclass correlation coefficient of BP in the awake and asleep periods ranged from 0.836 to 0.942 in the HIIT (P<0.05) and from 0.777 to 0.974 in the control sessions (P<0.05). The bias, limits of agreement, and pattern of distribution of awake BP were similar between HIIT and control sessions. However, for asleep BP, the bias and limits of agreement were not similar between HIIT and control sessions. In conclusion, in physically active adults, ambulatory BP after HIIT sessions presented good reproducibility only in the awake period.
