Good news for Boomers. Even if you've been sedentary for years, you can still bring back a lot of energetic youthfulness to your body through an exercise program of resistance, endurance and aerobic training. But if you haven't been working out in a while, then beware: a recommended exercise program for seniors is pretty different from that of 20 and 30 year olds. The biggest difference? Workout recovery time.
My friend Sammy just turned 68, and once again he's got a plan to "get in shape." As always, I asked him -- "In shape for what?"
This isn't the first time back to the gym for Sammy. In fact, making a play on his last name, I call him "Fits." As in, "Fits and Starts." Unfortunately, that's how he approaches keeping his body youthful and supple. Even more unfortunate, he ends up getting injured and having to sit around recuperating, while his hard earned muscle and flexibility fades away. Even though his friends have warned him about the dangers of the way he does his workouts, Sammy never pays attention. Are you in the same boat?
When muscles are worked, even for a short leisurely half hour walk, they use up some of the nutrient supply contained in the muscle cells and produce the normal waste products of work. The circulatory system -- your bloodstream -- carries off the waste and brings back more energy-producing nutrients; food to replenish the cells. As the muscles and the white connective tissues of tendons and ligaments are worked harder, they naturally use up more food and produce more waste. The process of getting rid of all the waste toxins and re-supplying all the nutrients is called "recuperation."
Another part of recuperation comes from torn muscle fibers. A hard workout causes beneficial damage to these fibers. Some of the fibers tear, causing desirable "microtrauma." When the muscles repair the damage, they build up stronger in order to better handle more microtrauma next time.
