It may seem like common sense that if you don't use your muscles, they'll eventually atrophy, yet so many people fail to apply this information in their daily lives. The older you get, the faster your muscles will atrophy if you're not regularly engaging in the appropriate exercise. Additionally, older muscles do not respond well to sudden or intense bouts of exercise, so the key to avoiding sarcopenia (age-related muscle loss) is to challenge your muscles with intense exercise on a regular basis throughout your life—and it's never too late to start.
Is Strength Training Sufficient to Prevent Age-Related Muscle Loss?
Sarcopenia, or age-related muscle loss, begins affecting people in their mid 20’s, initially at a rate of 1% loss of muscle mass per year, with accelerated rates as age advances and the muscle mass is replaced with fat.
Causes include:
- Hormonal changes
- Sedentary lifestyle
- Free Radicals
- Oxidative Stress damage
- Inflammation
- Insulin resistance
- Acidic Diet
This kind of exercise allows your body to produce human growth hormone (HGH) naturally. Yea, the same stuff that athletes take to cheat in their sport, however they take it in the form of a synthetic drug. HGH is also known as "the fitness hormone," and is essential for healthy aging, fitness, and yes, muscle building.
Additionally, you need to supply your muscles with the appropriate fuel at the appropriate time to provide them with the proper building blocks to produce new muscle tissue.
