Among older women, modest amounts of exercise can improve quality of life (QOL). Researchers from the Pennington Biomedical Research Center (Louisiana, USA) completed a six-month study involving 430 sedentary postmenopausal women (BMI of 25.0-43.0, with elevated systolic blood pressure). Each subject was assigned to participate in 1 of 3 exercise groups (exercising 1 hour 15 minutes/week; 2 hours 20 minutes/week, or 3 hours/week) or the nonexercise control group. Women in all three groups that exercised reported making the most gains in self-reported physical and mental well-being (as compared to the nonexercise group), and longer exercise times were associated with greater gains in QOL.
Even the most modest amount of regular physical activity can make a marked difference in a person’s quality of life.
