Build Muscle With Endurance Training

Read Transcript

Hi, I'm Dr. Wright. Have you thought about your satellite cells lately? You should. Satellite cells are the repair wizard that hang out on muscle fibers where they fix damage and rebuild breakdowns. But your satellite cells start slacking off as you age, which is one big reason muscle mass starts diminishing in your late 30s. By your 50s, you see the external effects.

Muscle tissue that was once sleek and firm is softer and squishier, and weaker. The first to go are your fast twitch fibers that power quick movements like spinning on the disco floor, or dribbling on the basketball court. Later, this muscle loss makes it harder to catch yourself if you stumble, raising the odds of bone breaking spills.

So how can you keep your satellite cells on the job? Take a brisk walk, go for a swim, or hop on the exercise bike that's gathering dust in the wreck room. New research shows that endurance exercise boosts the number of satellite cells by up to 47%. What are you waiting for? Get moving, and for more ways to stay strong, watch all of our health smarts videos, right here.
