Why strength depends on more than muscle

This is an article on the ScienceDaily website back in July. It covers a study done at the University of Nebraska-Lincoln that looked at how the nervous system adapts differently when a person lifts heavy weights (80% of max) compared to lifting lighter loads (30% of max).

Summary:
“Physical strength might stem as much from exercising the nervous system as the muscles it controls. The findings could explain why those who lift heavier weights enjoy greater strength gains than low-load lifters despite similar growth in muscle mass.”

This is a very interesting study because I have been rather puzzled by a few studies in the S&C field that found lifting lower loads resulted in similar muscle mass gains in trained individuals.
