Metabolic Effects of the Addition of Resistive to Aerobic Exercise in Older Men

15 overweight, older men who had recently completed a 6-month aerobic exercise program (treadmill walking, 45 min/d, 2 d/wk)

Addition of 4 months of resistive exercise (6 exercises on upper- and lower-body pneumatic-resistance machines, 2 sets, 15 repetitions each, 2 d/wk) to an aerobic exercise program (> or = 70% heart rate reserve for 30-40 min, 2 d/wk on treadmill)

Maintenance aerobic exercise program (continued the same maintenance treadmill aerobic exercise program)
