Clients with hypertension should avoid which type of muscle contractions?

Clients with hypertension should avoid isometric muscle contractions because this type of contraction involves holding muscles in a static position without movement. Isometric exercises can lead to a significant increase in blood pressure due to the sustained tension in the muscles, which puts stress on the cardiovascular system. When performing isometric exercises, the blood vessels constrict, and this can result in elevated blood pressure levels, posing potential health risks for individuals with hypertension.

In contrast, concentric, eccentric, and dynamic exercises typically involve movement, allowing for better circulation and generally resulting in less strain on the cardiovascular system. These types of contractions can be safely incorporated into a fitness regimen for individuals with hypertension, provided they are performed with appropriate intensity and under proper guidance.
