The effect of circuit resistance exercise before exhausting running on treadmill on fat, carbohydrate metabolism and energy expenditure in overweight and obese girls

AbstractBackground and Purpose: Stimulating the hormones and enzymes involved in the lipolysis, resistive exercises can increase lipolysis. The aim of this study was to examine the effect of circular resistive exercises before exhausting running on treadmill on fat and carbohydrate oxidation and energy expenditure in overweight and obese girls.Materials and Methods: Ten overweight and obese girls (weight range: 78.02 to 10.18 kg) performed two types of exercises: 1) performing circular resistive exercises before running on treadmill, 2) just running on treadmill without any circular resistive exercises. Running on treadmill was performed at the intensity of 75% of the maximum heart rate until they were exhausted, and the circular resistive exercises consisted of five stations, each with three rounds at 55% of 1RM (1Repetition Maximum). The respiratory gases of the participants were measured by a gas analyzer system for 30 minutes in the baseline and while running on the treadmill until exhaustion. The collected data was analyzed using multivariate analysis of variance (MANOVA) (α = 0.05).Results: It was found that fat metabolism during the activity in the first group (performing circular resistive exercises before running on treadmill) were significantly higher than the second group (just running on the treadmill). Energy expenditure and carbohydrate metabolism were not reported to be significantly different between the two groups of the study.Conclusion: Overweight and obese girls can use circular resistive exercises before running on a treadmill in order to increase their fat oxidation and reduce their body fat percentage.
