Exercise-only strategy not good enough for BP control in young adults, study suggests

UK: Recent research published in The Lancet e-Clinical Medicine does not support the use of medium-to-high intensity aerobic exercise training as the sole method of controlling blood pressure in young adults.

Exercise is recommended for young people with high blood pressure, but no trials have been conducted to determine its effectiveness at this age. As a result, Wilby Williamson and colleagues undertook this study to see if aerobic exercise, self-monitoring, and motivational coaching decrease blood pressure in this population.

The study was a two-arm, single-center, parallel superiority randomized clinical trial with open community-based enrollment of physically inactive 18-35 year old persons with awake 24 h blood pressure of 115/75mmHg-159/99mmHg and BMI of 35 kg/m2. The research was carried out at the John Radcliffe Hospital's Cardiovascular Clinical Research Facility in Oxford, UK.

Participants were randomized (1:1) to the intervention group, which received 16 weeks of aerobic exercise training (three aerobic training sessions per week of 60 minutes per session at 60-80 percent peak heart rate, physical activity self-monitoring with encouragement to do 10,000 steps per day, and motivational coaching to maintain physical activity upon completion). The control group was directed to hypertension education materials and lifestyle recommendations.
