Maximal isometric exercises are more often used for strength and conditioning and submaximal exercises are more often used in rehabilitation. Static strength training can also involve maximal muscle actions and examples here include pushing against a wall or heavy weight that you can not move no matter how hard you try.īoth submaximal and maximal isometric muscle actions can increase isometric strength and stimulate muscle growth. The force used to hold the weight still is not maximal as this would lift the weight further causing movement and a change in the muscle length and joint angle. Such as holding a weight out in front of you. Isometric exercises can be performed with submaximal muscle action. ![]() ![]() ![]() What is submaximal isometric muscle action? Examples include climbing, mountain biking and motocross (grip and upper body strength), wrestling, skiing (static strength required to stabilise the upper and lower body), and gymnastics. Some actions within a wide variety of sports require isometric or static strength. Therefore the joints involved do not move. This means that the muscle group being worked is under tension and producing a contraction but the muscle doesn’t change length. Isometric exercise refers to an exercise that uses an static muscle contraction.
