The heterogeneity in reported effects was reduced in higher quality studies , when physical activity was self-directed with some professional guidance and when there was on-going professional support .
Our review suggests that physical activity interventions have a moderate effect on self reported physical activity and cardio-respiratory fitness , but not on achieving a predetermined level of physical activity .
Due to the clinical and statistical heterogeneity of the studies , only limited conclusions can be drawn about the effectiveness of individual components of the interventions .
BACKGROUND Little is known about the effectiveness of strategies to enable people to achieve an increase in their physical activity .
OBJECTIVES To assess the effects of interventions for promoting physical activity in adults aged 16 years and older , not living in an institution .
A fall prevention program for elderly individuals. Exercise in long-term care settings.
The purpose of this research was to explore the role of exercise in preventing falls , specifically assessing the effectiveness of an ankle strengthening and walking program to improve balance , ankle strength , walking speed , and falls efficacy and to decrease falls and subjects ' fear of falling .  Sixteen individuals participated in the study which was conducted at two nursing homes . Subjects were assigned r and omly to an intervention or control group . The participants in the intervention group completed a 3-month supervised program of ankle strengthening exercises and walking . Descriptive statistics were used to characterize the sample , and differences in the least square means were used to assess the outcome variables ( i.e. , balance , ankle strength , walking speed , falls , fear of falling , falls efficacy ) before the exercise program , and again at 3 months and 6 months after the program for the intervention and control subjects . Findings for the intervention group from pretest to 3-month posttest were , for the most part , maintained or in the predicted direction , suggesting that regular exercise shows promise for preventing deterioration and improving fall-related outcomes for elderly nursing home residents
