Serious adverse events were rare , and no serious events were reported to be directly related to the exercise programme .
This review provides evidence that PRT is an effective intervention for improving physical functioning in  older people , including improving strength and the performance of some simple and complex activities .
BACKGROUND Muscle weakness in old age is associated with physical function decline .
Progressive resistance strength training ( PRT ) exercises are design ed to increase strength .

A high-intensity functional weight-bearing exercise program for older people dependent in activities of daily living and living in residential care facilities: evaluation of the applicability with focus on cognitive function.
BACKGROUND AND PURPOSE Knowledge concerning the applicability and the effect of high-intensity exercise programs is very limited for older people with severe cognitive and physical impairments . The primary aim of this study was to evaluate the applicability of a high-intensity functional weight-bearing exercise program among older people who are dependent in activities of daily living and living in residential care facilities . A second aim was to analyze whether cognitive function was associated with the applicability of the program . SUBJECTS The subjects were 91 older people ( mean age=85.3 years , SD=6.1 , range=68 - 100 ) who were dependent in personal activities of daily living and r and omly assigned to participate in an exercise intervention .  Their mean score for the Mini-Mental State Examination ( MMSE ) was 17.5 ( SD=5.0 , range=10 - 29 ) . METHODS A high-intensity functional weight-bearing exercise program was performed in groups of 3 to 7 participants who were supervised by physical therapists . There were 29 exercise sessions over 13 weeks . Attendance , intensity of lower-limb strength and balance exercises , and occurrence and seriousness of adverse events were the outcome variables in evaluating the applicability of the program . RESULTS The median attendance rate was 76 % .  Lower-limb strength exercises with high intensity were performed in a median of 53 % of the attended exercise sessions , and balance exercises with high intensity were performed in a median of 73 % of the attended exercise sessions . The median rate of sessions with adverse events was 5 % . All except 2 adverse events were assessed as minor and temporary , and none led to manifest injury or disease . No significant differences were observed in applicability when comparing participants with dementia and participants without dementia . In addition , there was no significant correlation between applicability and the MMSE score . DISCUSSION AND CONCLUSION The results suggest that a high-intensity functional weight-bearing exercise program is applicable for use , regardless of cognitive function , among older people who are dependent in activities of daily living , living in residential care facilities , and have an MMSE score of 10 or higher
