The Pentagon announced last week that it would open up all positions in the military to women — including combat positions. But science, and history, suggest the road to combat equality may be a difficult one.

What are the evolutionary explanations for why women are physically weaker than men on average , and is this difference adaptive? See figure one here. I suppose that something puts pressure on men to be physically stronger than women, but I don't see what it can be.

Strength and muscle characteristics were examined in biceps brachii and The women were approximately 52% and 66% as strong as the men in the upper and lower body respectively. The men were also stronger relative to lean body mass. microns2) and mean fiber areas ( vs microns2) than the women in.

He holds a Bachelor of Science in communications from the University of Texas, as well as a Master of Education in health and human performance from University of Houston. Williams is also a certified strength-and-conditioning specialist. It is widely known that, on average, men are stronger than women.

Strength and muscle characteristics were examined in biceps brachii and vastus lateralis of eight men and eight women. Measurements included motor unit number, size and activation and voluntary strength of the elbow flexors and knee extensors. Fiber areas and type were determined from needle biopsies and muscle areas by computerized tomographical scanning. The men were also stronger relative to lean body mass. The men had significantly larger type I fiber areas vs microns2 and mean fiber areas vs microns2 than the women in biceps brachii and significantly larger type II fiber areas vs microns2 and mean fiber areas vs microns2 in vastus lateralis.
