As we age, the type of exercise we choose to do becomes more important. Although any type of exercise improves fitness and blood sugar control, different styles of exercise yield different outcomes. Muscle cells heal and regenerate slower as a person gets older, which can make exercise tough. However, studies show that a program of interval training can improve muscle healing and regeneration.
Interval training consists of short bursts of intense activity followed by short periods of rest. While strength training does the most to enhance muscle mass, interval training builds endurance and allows you to exercise longer with less fatigue and pain. Furthermore interval exercise activates a plethora of genes that help your muscles create more energy and thus repair and regenerate faster. This variety of exercise may slow down some of the damage done by aging.
