According to a recent study, both 20-minute and 40-minute acute moderate-intensity exercises can reduce resting blood pressure in young hypertensive men with no antihypertensive drugs.

The key results were as follows:

• In the 20-minute exercise session (E20), systolic blood pressure (SBP) at 6 minutes following exercise was no different from the rest.
• In the 40-minute exercise session, (E40), SBP at 6 minutes following exercise was 14 mmHg lower than at the rest.
• Diastolic blood pressure (DBP) in the E20 session was the same as rest at 3 min following exercise and decreased by 4 mmHg at 6 minutes following exercise compared with the rest.
• DBP in the E40 session decreased by 3 mmHg at 3 minutes following exercise compared with the rest.
• The plasma nitric oxide (NO) levels of E20 and E40 increased significantly following exercise.
