A
muscle that is lengthening while it produces tension is performing an eccentric

Eccentric
contraction is the contraction that occurs when the load on the muscle
increases and at one point it reaches a stage where the external force on the
muscle is greater than the force that the muscle can generate. As a result, the
muscle is forced to lengthen due to the high external load.</span>
<span>Hypertension is another term for high blood pressure. This occurs when there is too much pressure put on the blood vessels. The heart gets affected because it is pumping against the pressure, which causes strain on the heart. This can cause thickening of the heart walls, which can lead to other heart problems.
Stroke occurs when there blood supply to the brain is reduced or obstructed. This deprives the brain of oxygen and other nutrients. The occurrence of stroke increases with blood pressure because there is persistent pressure on the vessels which can ultimately lead to stroke. </span>
