there is evidence suggesting that isometric exercises may be effective in lowering blood pressure. Isometric exercises are strength-training exercises that involve contracting muscles without joint movement, such as planks, wall sits, or static handgrip exercises.
Several studies have investigated the effects of isometric exercises on blood pressure, and some have found positive results:
A meta-analysis published in the journal Sports Medicine in 2015 reviewed 23 studies and concluded that isometric resistance training significantly reduced both systolic and diastolic blood pressure in individuals with hypertension (high blood pressure). The effect was particularly prominent when the exercise was performed at least three times per week for a minimum of four weeks.
Another study published in the Journal of Hypertension in 2016 found that isometric handgrip training significantly reduced blood pressure in individuals with hypertension. The researchers concluded that this type of training could be an effective adjunct to blood pressure-lowering medications.
A review article published in Current Hypertension Reports in 2017 also supported the use of isometric exercises for blood pressure reduction, citing evidence from various studies.
While these studies indicate that isometric exercises can be beneficial for lowering blood pressure, it's essential to note that exercise should not be considered a substitute for medical treatment in individuals with hypertension. It is always crucial to consult with a healthcare professional before starting any new exercise regimen, especially if you have any pre-existing medical conditions.
