Does isometric handgrip exercise reduce resting SBP and DBP in adult humans?
Isometric handgrip exercise effectively reduces resting systolic and diastolic blood pressure in adults, though evidence is limited by a small number of studies.
Isometric handgrip exercise is efficacious for reducing resting SBP and DBP in adult humans. However, the generalizability of these findings is limited given the small number of studies included.
Kelley et al. (2010) studied this question.
