A structured exercise program was not associated with a decreased risk for frailty among older adults. However, the beneficial effect of the exercise program on reducing major mobility disability was not affected by whether the participants were frail at baseline.
Combined aerobic and resistance activity increased physical performance more than aerobic or resistance training alone. A group of 160 sedentary individuals with average age 70 and BMI 35 were followed and evaluated at 6 months.
Results could be confounded by the fact that participants in the combined training group spent overall more time exercising than those who utilized only aerobic or resistance activities.
Study findings are a bit counterintuitive. Although atherosclerosis burden was higher in highly active middle-aged men, actual atherosclerosis disease was less due to structure and composition of plaques. “Exercise” plaques are mostly calcified, thus more stable and less likely to rupture, causing fewer acute coronary events.
