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 .
OBJECTIVES To assess the effects of PRT on older people and identify adverse events .
Effects of a group-based exercise program on the mood state of frail older women after discharge from hospital.
BACKGROUND Older people with somatic illnesses are at increased risk of depression . It is not known whether exercise alleviates depressive symptoms in frail , very old people recuperating from an acute illness . OBJECTIVE To determine the effects of a group-based exercise training program on mood . METHODS Sixty-eight women ( mean age 83.0 , SD 3.9 years ) who were hospitalized due to an acute illness , and were mobility impaired at admission , were r and omized into group-based 10-week strength training intervention ( N=34 ) and home exercise control ( N=34 ) groups . Twenty-four women in the training and 28 in the control group completed the follow-up . Measures of mood state with the Zung Self-Rating Depression Scale ( ZSDS ) were performed before and after the training intervention , and follow-up data was collected 3 and 9 months after the end of the intervention . RESULTS After the intervention , there was a significant improvement in mood in the intervention group compared to the home exercise control group : -3.1 ( SD 9.0 ) points vs + 1.3 ( SD 7.6 ) points ( p=0.048 ) and the positive effect was still apparent three months after the intervention ceased : -2.6 ( SD 7.7 ) points vs + 3.5 ( SD 9.7 ) points ( p=0.015 ) . Improvement of mood state at the first follow-up measurement was associated with the improvement in lower limb isometric muscle strength .  CONCLUSIONS Group-based exercise program organized in the context of a Finnish health care organization improved mood in frail older women recuperating from an acute illness
