Yes, it's true. It's a scientifically proven fact that muscle proteins are broken down and used for energy during aerobic exercise. However don't worry, you are constantly breaking down and re building muscle tissue anyway. This process is called "protein turnover." Your body is constantly alternating back and forth between anabolic (building) and catabolic (breaking down) cycles. That's just a normal part of life. Your aim is simply to tip the scales slightly in favor of upping the anabolic side and reducing the catabolic side just enough so you stay on the anabolic side and you gain or at least maintain muscle.



Osteoporosis is a disease characterized by low bone density which can lead to an increased risk of fracture. According to the National Osteoporosis Foundation, osteoporosis is responsible for more than 1.5 million fractures annually, including over 300,000 hip fractures, 700,000 vertebral fractures, 250,000 wrist fractures, and 300,000 fractures at other sites. The good news is that exercise may increase bone density or at least slow the rate of decrease in both men and women. It may not work for everyone, and the precise amount and type of exercise necessary to accrue rewards is unknown, but there is evidence that it can help. In children there is good news, too. It seems that active children have greater bone density than sedentary children and that this may help prevent fractures later in life.



Do you sometimes get bored with your aerobic exercise? Do you sometimes feel like you're not getting the results you should from your aerobic exercise? If so, then aerobic cross-training is for you.





Step it up. Get a pedometer and see how many steps you normally take in a day. Then try to increase your number of steps gradually over the next limited months. Several organizations, such as Shape Up America and HealthPartners, have launched programs to encourage people to work up to 10,000 steps a day.



Imagine that you're exercising. You're working up a sweat, you're breathing hard, your heart is thumping, blood is coursing through your vessels to deliver oxygen to the muscles to keep you moving, and you keep the exercise for more than just a limited minutes. That's aerobic exercise; any exercise that you can keep for more than just a limited minutes while your heart, lungs, and muscles work overtime. In this article, I'll discuss the mechanisms of aerobic exercise; oxygen transport and consumption, the role of the heart and the muscles, the proven rewards of aerobic exercise, how much you need to do to reap the rewards, and more.
