Middle-aged sedentary females (42.8 +/- 4.1 years, mean +/- SD) were subjected to aerobic exercise (AE, n=20) and aerobic exercise with weightlifting (AEWT, n=18) 3 times a week for a period of 20 weeks to determine changes in body weight, body fat, blood pressure, heart rate, and serum lipid profile. At the end of training program, subjects in both groups lost weight and body fat. Cardiac parameters and serum lipid profile also decreased in both groups. These beneficial changes were noted at a greater extent in the subjects performing AE than in the subjects performing AEWT. In conclusion, light but continuous exercise is sufficient to achieve health benefits in middle-aged sedentary women. (C) 2013 The Authors. Published by Elsevier Ltd.
