DANTAS, Thiago Prado et al. Assessment of body strength, power and temperature in a crossfit session. Motri. [online]. 2018, vol.14, n.1, pp.311-315. ISSN 1646-107X.

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. Thus, the objective of the study was to analyze the effect of a Crossfit® session on body strength, power and temperature. Participating in the study were 10 subjects with experience in the modality who were submitted to a pre-test, a intervention of a Crossfit® class and a post test, the tests were of jumps, flexibility, trunk strength and manual grip, potency in limbs (MMSS) and verification of thermal asymmetry. There were significant differences (p <0.05) in the jump-on-motion (CMJ) tests (49.03 ± 3.13 vs. 45.27 ± 4.20), and power in SBM (762.50 ± 171, 54 vs. 696.40 ± 162.89) and arm thermal asymmetry (0.27 ± 0.21 vs.0.55 ± 0.34). From the above it is verified that it is necessary to follow the Crossfit® practitioners, especially in the mentioned tests, since a single session showed to be able to promote physical imbalances and these in a repetitive way could generate local overloads.
