Regular, vigorous physical exercise confers numerous
benefits. These include markedly postponing disability, prolonging
life, strengthening bones, improving cardiac function
and quality of life, reducing frailty, and retarding progression
of aging markers in many organ systems1,2,3,4.
Effects of exercise upon radiographic osteoarthritis (OA),
particularly of the knee, have also been examined, partly
because the original “wear and tear” hypothesis of OA
development suggested that excessive weight-bearing exercise
might cause accelerated joint damage and might result
in more knee replacement surgery.
