what is mechanical tension

Mechanical tension is a term used in physics and exercise science. In physics, tension is described as the pulling force transmitted axially by the means of a string, a rope, chain, or similar object, or by each end of a rod, truss member, or similar three-dimensional object). At the atomic level, when atoms or molecules are pulled apart from each other and gain potential energy with a restoring force still existing, the restoring force might create what is also called tension). In exercise science, mechanical tension is the force that you apply to muscles through a form of resistance or weights, to create tension. It is one of the three potential mechanisms that have been proposed to stimulate muscle growth, along with metabolic stress and muscle damage. Recent evidence suggests that mechanical tension is the primary and potentially only mechanism responsible for triggering hypertrophy. Mechanical tension is created by a muscular contraction against an opposing force such as weights or bodyweight movements. It is essential for stimulating muscle growth and strength gains. To make sure you are creating enough mechanical tension during your workouts, it’s important to focus on proper form as well as gradually increasing the weight you’re lifting over time.
