Researchers studied whether isometric handgrip training — a type of hand-squeezing exercise — could reduce ambulatory blood pressure (the pressure measured throughout the day) in people with high blood pressure. This trial involved five Brazilian research centers and compared people who performed supervised hand-squeezing exercises to people who did stretching and relaxation exercises over 24 weeks.
Previous research suggested that hand-squeezing exercises might lower blood pressure measurements taken in a clinic, but doctors weren't sure whether this training would actually reduce the blood pressure readings taken throughout a normal day, which is a better measure of real-world cardiovascular risk.
Participants visited a research center three times per week for 24 weeks. Some participants performed hand-squeezing exercises (four sets of 2-minute contractions using alternating hands at moderate intensity), while others did stretching and relaxation exercises. Blood pressure was measured at the start, after 12 weeks, and after 24 weeks to see how the training affected daily blood pressure readings.
