A new study has provided compelling evidence that high-intensity interval training (HIIT) and combined training are effective in lowering high blood pressure, marking the first time their impact on 24-hour ambulatory blood pressure has been demonstrated. The research, published in the British Journal of Sports Medicine, pooled data from 31 studies involving 1,345 individuals diagnosed with hypertension.
Key Findings
The analysis revealed that HIIT, combined training (mixing aerobic and resistance exercises), and traditional aerobic exercise such as jogging, cycling, or swimming all produced consistent benefits in managing blood pressure. However, the study indicated that evidence for the effects of yoga, Pilates, and recreational sports on blood pressure remains limited and requires further investigation.
Expert Commentary
Regina Giblin, a senior cardiac nurse at the British Heart Foundation, welcomed the findings. She emphasised the crucial role physical activity plays in controlling high blood pressure and recommended that adults engage in at least 150 minutes of moderate-intensity activity per week. “This study reinforces that exercise is a cornerstone of blood pressure management,” Giblin stated.
Public Health Implications
High blood pressure affects one in three adults in the UK, often without noticeable symptoms. If left untreated, it significantly increases the risk of serious conditions such as heart disease, stroke, and kidney disease. The study underscores the importance of regular blood pressure checks and incorporating physical activity into daily routines.
Experts advise that individuals with hypertension consult their healthcare provider before starting a new exercise regimen, particularly high-intensity workouts. The findings add to a growing body of evidence supporting exercise as a non-pharmacological intervention for hypertension.
