When the right leg is raised toward the ceiling while keeping the right knee straight, the right quadriceps muscles flex isometrically.
When a muscle contracts isometrically, it fires or activates with force and tension, but there is no joint movement. In other words, the joint is immobile, the muscles don't stretch or shorten, and the limbs don't move. Although there is no movement at the joints or change in the length of the muscle fibres during this type of muscle contraction, the muscle fibres still activate. Pushing firmly against a wall or performing a wall sit exercise (sitting with your back against the wall) are two excellent examples of isometric exercises. Exercises that are isometric are substantially easier on the joints throughout the long and short terms. They don't put additional strain on the joints, yet they nevertheless trigger the muscle fibres to fire. Isometric exercises are so frequently employed in rehabilitation programmer for people who have had joint problems or concerns.
