摘要：Given that Brazilian Jiu-Jitsu (BJJ) is a frequent option for adolescents around the world, the high quantity of movement should modify motor behavior and improve fitness and physiological control in young practitioners. The purpose of the study was to verify the differences in fitness conditioning and metabolic responses in teenage BJJ athletes. Thirty-nine subjects voluntarily participated in this study, and were divided according to 3 groups: (a) 13 Brazilian Jiu-Jitsu athletes (BJJ); (b) 13 active teenagers (AT); and (c) 13 sedentary teenagers (ST). All BJJ had more than 1 yr of practice and one championship with BJJ experience. The anthropometric profile (weight, height, waist circumference, waist to height ratio, %fat, and muscle mass) was analyzed along with a flexibility capacity (sit and reach test). Maximum oxygen intake (VO2 max), yo-yo test, and fasting glucose, and lipid profile (TC, HDL, TG, LDL, and VLDL) were also obtained. Statistical analysis consisted of descriptive methods and Shapiro Wilks normality test. To detect differences between groups, a one-way ANCOVA with post hoc tests (Tukey's) were used with statistical significance set at P≤0.05. There were no significant changes in any body composition variables. Regarding the fitness conditioning, adolescents in BJJ presented better flexibility capacity (P=0.01) and lower values of select components of the lipid profile (P=0.01, LDL and triacylglycerol) when compared to the AT and ST groups. The findings indicate that the BJJ athletes have better flexibility and lower levels of LDL and triacylglycerol when compared to the active and sedentary teenagers.
