Background & Aims: Estimating resting metabolic rate (RMR) is one of the main determinants of an athlete's energy needs. This study aimed to investigate the RMR of bodybuilding athletes using indirect calorimetry (IC) and compare it with predictive formulas proposed in the scientific literature., Methods: 71 volunteers divided into four experimental groups: active control group for women (CGW; n = 16); active control group for men (CGM; n = 17); bodybuilder women (BBW; n = 13); and bodybuilder men (BBM; n = 25) were evaluated. The body composition was performed using the bioelectrical impedance (BIA), and the RMR was measured using an IC. The data obtained from the BIA instrument were used to calculate the RMR of all volunteers using six equations. Data normality was tested, and the unpaired t-test compared anthropometric parameters, body composition, and RMR. The Bland-Altman (B&A) plot was used to analyze the agreement between IC, BIA, and predictive equations, and the difference between the methods was calculated. An analysis of covariance (ANCOVA) with Bonferroni post hoc was used for RMR analysis and adjusted for body weight and skeletal muscle mass., Results: The main findings indicated that the Johnstone equation showed a large discrepancy underestimating the RMR of BBW and BBM when compared to IC, and the De Lorenzo and Tinsley equations (a) approached the more accurate analysis method of measuring RMR in BBW and BBM, respectively., Conclusion: Professionals who work with bodybuilding and performance will be able to use the present study to improve their nutrition support., Competing Interests: Declaration of competing interest The authors declare that there is no conflict of interest., (Copyright © 2022 European Society for Clinical Nutrition and Metabolism.

Effects of 2 types of resistance training models on obese adolescents' body composition, cardiometabolic risk, and physical fitness. J Strength Cond Res 34(9): 2672-2682, 2020-The main objective of this study was to investigate the effects of 2 types of resistance training (RT) models in conjunction with interdisciplinary interventions by other health professionals to reduce the body fat and cardiometabolic risk of obese adolescents while improving their general health-related physical fitness. The 12-week analyses involved 18 male adolescents who were split into 2 groups (weight lifting: n = 9 and functional: n = 9), with equalization according to the primary muscle group (whenever possible), the effort:pause ratio, and intensity. The results showed reductions in fat mass and body fat, as well as in waist and hip circumferences (p < 0.05) after the intervention period. However, no significant differences were observed in terms of the body mass, body mass index, neck circumference, systolic and diastolic blood pressures, and for lean mass (p > 0.05) after the respective period. Maximal isometric strength, abdominal strength resistance, flexibility, and maximal oxygen consumption all produced significant increases after the interventions (p < 0.05). There were reductions in low-density lipoproteins and triglyceride levels after the intervention period (p < 0.05). For fasting glycemia, high-density lipoproteins, and alanine aminotransferase, no differences were observed (p > 0.05). In addition, no differences were observed in rating of perceived recovery, internal training load, or caloric intake (p > 0.05). With the results presented, it is concluded that both RT methods were effective at reducing both fat mass and body fat, thus improving health-related physical fitness components and decreasing cardiometabolic risk.
