Comparision of fat oxidation rate at crossover point during exercise among women with different body mass index

WOS: 000458742100012Purpose: The aim of this study was to evaluate the relationship between metabolic responses and fat oxidation at basal metabolic rate (BMR) and crossover point during performance tests in sedentary young women with different body mass index (BMI). Materials and Methods: Thirty sedentary women who were classified as normal weight (n=10), overweight (n=10) and class I obese (n=10) according to their body mass index participated in this study. Participants' basal metabolic rate and metabolic responses during exercise were measured by indirect calorimetry (Quark B2). Exercises were performed with gradually increased test protocols on treadmill. Results: Body mass index of groups were significantly different than each other. Body weight normalized peak oxygen uptake value reduced significantly with weight gain. Fat oxidation rate at crossover point increased with weight gain and the difference between normal and class-I obese women was found to be significant. Comparison of energy expenditure at crossover point for normal weight group was found to be significantly lower than overweight and class-I obese women. Conclusion: Fat oxidation rates and total energy expenditure increases with body mass index at crossover point
