Flexibility - Decreases with age.
Tendency to put on weight
Strength - Decreases with age.
Younger people will not achieve
maximal strength until they're fully
grown
Oxygen capacity - Reduces with age
and the heart becomes less efficient.
The arteries gradually lose their
elasticity, increasing blood pressure and
reducing blood flow
Skill levels - Can improve
with age and experience -
as well as improving as
we get bigger and stringer
The older you get, the longer
you take to recover from
injuries. More chance of
suffering a blood disorder or
disease and a gradual build up
of wear and tear
