Lifting Builds Muscle & Bone

It's a well-established fact that resistance training builds stronger and larger muscles, especially when complemented by the right nutrition at optimal times. Many studies have also linked weight lifting with stronger bones. New research published in the International Journal of Sport Nutrition & Exercise Metabolism confirms that theory while offering some insight on why it's true.

Ten healthy active men between the ages of 22 and 32 were put through a week-long protocol of high-impact and resistance training. Their calcium intake was strictly regulated to gauge calcium loss. Then the same measurements were taken after a week of restricted activity (no exercise). Calcium loss was about 15% lower during the training cycle, and scientists theorized that weight training improved the rate of bone mineralization.

The Bigger Picture: While calcium and vitamin D supplements are important elements in the equation, this study suggests that regularly hitting the gym can play a very significant role in maintaining bone health. It also works wonders for weight control, fatigue fighting and overall mood improvement. The holidays are over, so it's time to get back on track.

ten men is not an acceptable sampling size. Plus the change in calcium loss was only 15%? There needs to be a lot more research done on this topic. More men, wider age range, longer period.
