This review found that muscle strength , balance , and endurance can be improved by physical activity in people aged 40 - 65 years .
There were bigger effects on muscle strength from programs that used resistance exercises , indicating the need to include a resistance training component if strength enhancement is the goal
QUESTION Can physical activity  in adults aged 40 - 65 years enhance strength and balance and prevent falls ?
A home-based, transtheoretical change model designed strength training intervention to increase exercise to prevent osteoporosis in Iranian women aged 40-65 years: a randomized controlled trial.
Physical activity ( PA ) helps to prevent osteoporosis , but older women are often sedentary . This study used a pre-post r and omized controlled design to evaluate a 12-week exercise education intervention program based on the stages of change ( SoC ) and processes of change from the transtheoretical change model ( TTM ) to improve adherence with strength and balance training recommendations at levels sufficient to prevent osteoporosis in Iranian women aged 40 - 65 years . The home-based exercise prescription consisted of strength and balance training that was progressive , individually tailored and included a walking program . Individuals in the training group ( n=61 ) had a positive , significant progression in psychological SoC ( P<0.001 ) , whereas no progression in stages occurred in the control group ( n=55 ) . After the intervention , the training group demonstrated significant improvements in PA , lower body muscle strength , static and dynamic balance , with no significant changes in the control group . These results support the applicability of the TTM for a PA intervention and indicate that this training program is very effective in improving balance and lower body strength in older women
