Key result
Handgrip during interval training prevents a ~12 mmHg drop in DBP during final sprints.
Why the study?
Consistent evidence was lacking regarding acute hemodynamic adjustments when combining interval training with isometric handgrip exercise.
Does the addition of isometric handgrip contraction to interval training modulate acute hemodynamic responses in male volunteers?
RCT (n=7)
Simple random

First RCT data on combined HG isometric and interval training hemodynamics; extends separate-exercise literature to their association.
Sacramento et al. (2024) reported an RCT. Handgrip (HG) during interval training vs. Interval training without handgrip was evaluated on Drop in diastolic blood pressure (DBP) in the last sprint. The use of handgrip during interval training attenuated the drop in diastolic blood pressure in the last sprint (drop of 0±19.6 and 6±13.0 mmHg with 30% and 60% handgrip vs 12±13.2 mmHg without).
