How to remember the difference between isometric, isotonic, and isokinetic exercises Isokinetic exercise can also be used to assess the muscle function of athletes or people with specific injuries. This can help athletes like baseball pitchers or javelin throwers learn to use their maximum force at higher speeds, Smart says. The equipment used for isokinetic exercise, known as an isokinetic dynamometer, keeps your muscles moving at a consistent speed, which can then be raised with ongoing training. “It is mostly used to train athletes to improve their running or throwing by improving the speed at which they can move their limb/body or a weight,” Smart says. Isokinetic exercise is a type of workout that involves specialised machines and is not often used by the average person. Studies show that athletes who lift weights have higher bone mass and density, compared with other types of athletes. Isotonic exercise can also help build up bone density, which can be beneficial for people at risk of, or with, osteoporosis, a condition where bone mass is depleted. A large 2017 study found that women who did strength-training exercises had a 30 per cent lower rate of diabetes, compared with women who didn’t train. Isotonic exercise is especially useful for people at risk of or diagnosed with diabetes, Smart says, as it can help improve blood sugar regulation. “This type of training is what most people do in the gym and has benefits for preserving strength as we age,” says Smart. Isotonic exercise can help strengthen and build muscles so that you can move through all types of motion with greater ease. Squats are a great isotonic exercise to strengthen your glutes. Squats are another form of isotonic exercise, using your body weight to tense the muscles and moving your knees through their full range of motion. Isotonic exercise involves putting a constant amount of weight or tension on your muscles while moving your joints through a full range of motion.Īn example is bench-pressing, as the amount of weight stays the same and your joints bend and straighten all the way. They found that both people with normal and high blood pressure who did isometric training lowered their systolic blood pressure by 7mm, which the researchers say could be enough to prevent an issue like a heart attack. In 2014, Smart and his colleagues published a review of 9 studies looking at isometric exercise and blood pressure. “But my work and others has recently shown clearly that isometrics is the best way to lower blood pressure with exercise.” Smart, a professor of clinical exercise physiology at the University of New England. “For years, we avoided in people with high blood pressure or heart disease,” says Neil A. Evidence is growing that isometric exercise may help lower blood pressure as well. Isometric exercise is often recommended for people who are recovering from an injury, or who suffer from joint pain like arthritis. For instance, if you train by doing a plank pose, it can help you hold a plank position for an extended period of time, but won’t necessarily help you do more pushups. Isometric exercises are good for maintaining your strength and stability. Planks are a great isometric exercise to build core strength. A prime example is holding your body in a plank position – you stay at the top of a push up without bending your elbows. Isometric exercise is a type of low-impact exercise that involves straining your muscles without moving or bending your joints.
