Introduction: Crossfit® is characterized by increased high-intensity exercise, varied and functional movement, such as Olympic lifting, weight and gymnastics movements combined in high-intensity workouts. The training complexity and the large number of individuals linked to Crossfit® increases the need for studies to evaluate the effect of this training modality on the musculoskeletal and metabolic system. Aims: to analyze the effect of a Crossfit® session on the cardiac parameters, strength, power and body temperature. Methods: Ten subjects, all males with at least 12 months' experience in Crossfit® and aged between 18 and 35 years (29 ± 6.32 years) participated in the study. The test consisted of a single Crossfit® session, composed of the following WOD: 7 rounds of 20 american swing reps, 15 wall ball and 50 double unders, and the control session consisted of a traditional bodybuilding session consisting of four sets of 10 repetitions of Leg press and four sets of 10 repetitions of bench press with rest of two minutes, being the interventions separated by 72 hours. Results: The results showed significant differences in SBP immediately after the intervention (p = 0.002) and 40 minutes later (p = 0.021) of the experimental group in relation to the control, in the diastolic BP (p = 0.042) and in the mean BP in 40 minutes post (p = 0.004) in comparison to the control and significant differences (p <0.05) in the jump-on-motion (CMJ) tests (49.03 ± 3.13 vs. 45.27 ± 4.20), and power in MMSS (762.50 ± 171.54 vs. 696.40 ± 162.89) and arm thermal asymmetry (0.27 ± 0.21 vs.0.55 ± 0.34). Conclusion: From the first session of Crossfit® it is possible to conclude that the dose-response curve of the exercise in normotensive individuals declines, as well as the affection of physical changes, which if they are repetitive can generate local overloads.
