Results of the studies of exercise are instructive of potential benefits for older persons following hip fracture. Most of the work to date has been restricted to relatively healthy, select samples of older persons who have been recruited into rigorously controlled randomized experiments. Hence, while they are efficacious in benefiting a select group of older persons, it is not known whether these interventions will be accepted by a frail older population which has become suddenly disabled by a hip fracture, nor is it known whether these interventions will be beneficial to this group which is losing bone, muscle and function at an accelerated rate.
