Muscle Loss From Overtraining

Muscle Loss From Overtraining There's a mindset in the weight room that if a little is good, more must be better. Another old saying warns against getting too much of a good thing, and that's the take home message from an overtraining study published in the Journal of Strength and Conditioning Research.

Using lab rats as their subjects, scientists forced one group to weight train with heavy resistance and didn't allow them enough time for recovery being sending them back to the lab's weight room for another workout. A different group of rats didn't exercise. Compared to the inactive rats, the overtrained group lost about 17% of plantaris muscle cross sectional thickness after 12 weeks. Production of the natural growth hormone IGF-1 was suppressed 43% from normal levels.

True Strength Moment: It's a common misconception that muscle is built bigger and stronger in the weight room. Struggling to raise a stack of plates over and over actually breaks muscle fibers down, as this study helps illustrate. Muscle is built bigger and stronger during recovery, which can take up to 48 hours to complete. Don't fall into the trap of working the same muscle groups every day.
