Upper Body Strength And Fighting Prowess

As a follow up to my last post on the face of a fighter, there’s a part of the paper it points out that talks about the belief that upper body strength is the or one of the most important factors for human fighting prowess. Here’s the relevant except….

Anatomical evidence supports the view that, for ancestral humans, the single most important factor driving the differential ability to inflict costs was upper-body strength. In humans, the view that upper-body strength is more relevant for fighting than lower-body strength is empirically supported by the considerable sexual dimorphism in human upper-body size and strength (for review see Lassek & Gaulin in preparation). Men, for example, have approximately 75 per cent more muscle mass than women in the arms, but only 50 per cent more muscle mass in legs. Although ancestral humans were zoologically unusual in their use of tools in some types of aggression, the force driving the weapon remains largely a function of upper-body strength (Brues 1959).

Given that upper body strength seems to be greatest with Mesomorphs, and that Somatotypes have a heredity component, it would seem that thus upper body strength will have a heredity component.

Something not surprising to me, since I’ve observed (in my personal experience) that fighters tend to run in the family.
