Key result
A single session of isometric handgrip exercise performed with different intensities and volumes did not acutely reduce blood pressure or other cardiovascular parameters in hypertensive patients.
Why the study?
Does a single session of isometric handgrip exercise at different volumes and intensities reduce blood pressure in hypertensive patients?
Population
12 hypertensive patients, mean age 58±5 years old.
Comparison
Single session of isometric handgrip exercise at… vs Control session (randomized crossover design).
Design
RCT, Randomized crossover trial (sessions performed in a random order)
Follow-up
30 minutes post-exercise

Single isometric handgrip session does not acutely lower BP in hypertension; challenges assumptions of immediate effects and directs research to chronic protocols.

p-value: p=>0.05
A single session of isometric handgrip exercise, regardless of intensity or volume, does not acutely reduce blood pressure in hypertensive patients.
Silva et al. (2018) conducted an RCT in Hypertension (n=12). Isometric handgrip exercise vs. Control session (remaining seated without performing exercise) was evaluated on Pre- to post-exercise changes in systolic and diastolic blood pressure, heart rate, and rate-pressure product (p=>0.05). A single session of isometric handgrip exercise performed with different intensities and volumes did not acutely reduce blood pressure or other cardiovascular parameters in hypertensive patients.
