Power is defined as the rate work is performed. It is different from strength. Strength is the force that is exerted by a muscle, or a group of muscles against resistance. Power is related to the ability to perform activities of daily living and mobility. According to med bridge, a continuing education platform, 20% of individuals over 70 and 80% of individuals over 90 are affected by mobility disability. Muscle performance training allows to decrease this rate of disability. One rep max is the amount of weight a person can lift for one repetition. During a workout, the intensity, one rep max percentage can help determine how much or how many repetitions should be performed of a certain weight. Many older adults can exercise at 70 to 80% of one rep max. This allows for the intensity to be anywhere between eight repetitions to 13 repetitions of a resistance exercise. The good news is most older adults can safely work out within this intensity level and see results.
Stay safe and continue exercising. Always make exercise fun.
