From: Substrate utilization during submaximal exercise in children with a severely obese parent
Respiratory exchange ratio (RER) (Panel A) and the percentage of fat utilization contributing to total energy needs (Panel B) during cycling exercise at a workload of 15 W before (Pre Training) and after (Post Training) a 4 week endurance-oriented exercise training program in children with lean/non-obese parents (n = 3) or at least one severely obese parent (n = 3). RER tended to decrease (P = 0.06) and fat utilization tended to increase (P = 0.07) with exercise training regardless of group. Mean ± SE.
