OBJECTIVE: To determine the impact of intermittent high-intensity exercise training ([IHIE], including high-intensity interval training [HIIT] and recreational team sports [RTS]) on systolic (SBP) and diastolic blood pressure (DBP) in adults with pre- to established arterial hypertension. DATA SOURCES: MEDLINE, Cochrane Library, Embase, and SPORTDiscus. ELIGIBILITY CRITERIA: Randomized controlled trials (RCTs) comparing the impact of IHIE on BP versus a non-exercise control. DATA COLLECTION AND ANALYSIS: Two authors independently conducted all procedures. Mean differences were calculated using random-effects model. The certainty of the evidence was assessed with GRADE. RESULTS: Twenty-seven RCTs (18 HIIT and 9 RTS) were analyzed, with median duration of 12 weeks. Participants' (n = 946) median age was 46 years. Overall, IHIE decreased SBP (-3.29 mmHg; 95% CI: -5.19, -1.39) and DBP (-2.62 mmHg; 95% CI: -3.79, -1.44) compared to the control group. IHIE elicited higher decreases in office SBP and DBP of hypertensive subjects (SBP: -7.13 mmHg, [95% CI: -10.12, -4.15]; DBP: -5.81 mmHg, [95% CI: -7.94, -3.69]) than pre-hypertensive (SBP: -2.14 mmHg, [95% CI: -4.36, -0.08]; DBP: -1.83 mmHg, [95% CI: -2.99, -0.67]). No significant differences were found between HIIT (SBP: -2.12 mmHg, [95% CI: -4.78, -0.54]; DBP: -1.89 mmHg, [95% CI: -3.32, -0.48]) and RTS (SBP: -4.18 mmHg, [95% CI: -7.19, -2.43]; DBP: -4.04 mmHg, [95% CI: -6.00, -2.09]). These findings present low/very low certainty of evidence. No adverse cardiovascular events were reported. CONCLUSIONS: IHIE appears to be safe and to promote substantial decreases in BP, particularly in patients with hypertension. However, the certainty of evidence was low/very low.

AIM: The aim of this study was to assess relationships between cardiac autonomic regulation after exercise and different types of single-bout exercise of a maximal intensity and of a similar duration. METHODS: The study group consisted of 30 males (23 ± 2 year old), which was separated into three subgroups. Groups A and B performed exercise interventions (continuous or intermittent), while group C represented the control group. Heart rate variability (HRV) was monitored continuously over 30 min after the exercise and consequently during a 6 h period following intervention. Spectral analysis parameters of HRV (total [PT], low- [PLF], high- [PHF] frequency power, LF/HF, and PLF in normalized units [LFnu]) were determined over 5 min intervals. Heart rate recovery (HRR) was also analysed. RESULTS: There were not significant differences between groups A and B for the entire HRV monitoring (P<0.05) or in the relatively expressed HRR. The cardiac autonomic modulation expressed by PT, PLF, and PHF fully recovered in 120 min after exercise, whereas LF/HF and LFnu did not significantly differ (P<0.05) from the control group 60 min earlier. CONCLUSION: Cardiac autonomic recovery after all-out exercise is type non-dependent and sympathovagal balance restores faster than the absolute HRV magnitude.
