Although PRT is known to improve strength, the major controversy regarding
it is whether it is the most effective means of improving muscle power and
mobility skills. Declining muscle power is well documented in older adults and
has also been more strongly associated with declines in functional performance
than declines in strength. High-velocity training has been shown to improve
power [40], and comparison between this and PRT alone is in the earliest stages.
Another option to improve function may be to add task-specific exercises to
PRT. These exercises simulate daily functional tasks to the greatest extent possible
and are associated with functional gains [5].
