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 .
The impact of exercise training on blood lipids in older adults.
Increasing physical activity is often prescribed to improve blood lipids ; however , the efficacy of exercise in improving blood lipids in older adults is not clear . The objective of this study was to examine the effects of different exercise modes on blood lipid levels in previously sedentary older adults engaging in a 16-week exercise intervention .  One hundred thirty-one subjects ( mean age 74.6+/-6 years ) were r and omly assigned to a resistance training group , aerobic walking group , combined exercise group , or nonexercising control group .  Blood lipids were measured at baseline , 8 weeks , and postintervention . Exercise mode did not impact blood lipids . All groups had lower lipid levels over time . Total cholesterol , low- and high-density lipoprotein , and triglycerides were significantly lower . The decrease in all groups , including the controls , may be due to a seasonal effect in older adults that has been documented in younger individuals
