When you search the Web for references
to human performance...
There are two distinctly different
definitions for human performance. You are looking at it here in
the context of human health, so you think of human performance in
terms of physical training. That's fine, except the business world has
an entirely different definition for the same term. In the business
world, human performance refers to the study of ways people
interact with their work environment.
So when you are doing web searches for
human performance, be sure to include health in your search
terms.
