One of the leading incubators for physical activity (PA) are the fitness academy’s, with a variety of appealing options. Indeed, in 2013, 61.1% of PA population chosen Fitness Sports among all others, and people with more than 25 years choose workout in fitness classes as the top 10 sports choices. Thus, the aim of this study was to characterize the intensity of effort analyzing and comparing two training fitness options, Jump (JCT) and Jump-Circuit (JCCT) class training, regarding their metabolic and energetic demands in non-laboratory environment, checking if they comply with moderate to vigorous physical activity intensity recommendations. Therefore, we used a sample of 42 regular participants of JCT and JCCT (31.52 ± 8.80 years). Study involved the completion of a class of JCT or JCCT, with participants equipped with a portable gas analyzer COSMED ® K4b2. Statistical procedures contemplated the comparison between groups by independent Student T-test and Analysis of Covariance with adjustment for age, with the significance level set at 5%. We found that, on average, the Jump group (JG) achieved higher values in absolute VO2, relative VO2, MET and Energy Expenditures variables, with significant differences (P<0.05) in comparison with the Jump-Circuit group (JCG), even after adjustments for age. Regarding the RER, HR and substrate utilization percentages, there were no significant differences. From the data obtained, both options have a similar recruitment of energy substrates, with small differences of intensity between them, and achieving the moderate to vigorous physical activity recommendations.
