摘要

Purpose This study was designed to analyze the differences in metabolic indicators and energy expenditure (EE) between two models of health club fitness classes: Aerobic Fitness Class (AFC) and Strength Fitness Class (SFC). Methods Fifteen adult women (mean±standard deviation: age, 29.0±3.3 years; height, 161.8±4.8 cm; body mass index, 21.5 ±1.6 kg/m2) participated in the present study. Maximum oxygen uptake (VO2max) and maximum heart rate (HRmax) were measured directly during a maximal treadmill test. During AFC and SFC sessions, heart rate (HR), oxygen uptake (VO2), respiratory exchange ratio (RER), metabolic equivalents (MET), percentage of fat oxidation (%FAT), percentage of carbohydrate oxidation (%CHO) and EE were assessed by indirect calorimetry using a portable gas analyzer (K4b2). Student's paired samples t test was used to analyze differences between AFC and SFC. Significance level was set at 5%. Effect sizes (Cohen's d) were observed. Results There were greater values during AFC in comparison with SFC on the following variables: VO2 (1959.3 ±273.2 vs. 1122.7+187.7 ml kg"1 mirT1;p<0.001; ES = 3.69); HR (161 ± 14 vs. 133 + 17 bpm; p<0.001; ES = 1.86); MET (10.0± 1.2 vs. 5.8±0.9 MET;p<0.001; ES=4.1); total EE (259.6±24.9 vs. 151.7 + 22.3 kcal;p<0.001; ES=4.73); %VO2max (76.9±8.6 vs. 44.3 ±8.1%;p<0.001;ES =4.04); %HRmax (84.2±5.8 vs. 69.7±1.9%;p<0.001; ES = 2.17) and CHO oxidation rate (139.9 ± 16 vs. 82.4 ±13.8 kcal IT1; p < 0.001; ES = 3.98). Further, CHO was the main substrate for both classes. Conclusion These results suggest that AFC induces greater EE than SFC. Moreover, engaging AFC or SFC 3-5 times a week seems enough to achieve international physical activity recommendations per week to promote several health benefits. Finally, carbohydrate is the main energy supply for both types of fitness classes.
