Brief Summary
The objective of the present study was to evaluate the MPF and the perception of effort of professional jiu jitsu athletes from carbohydrate intake at different moments. Twelve jiu jitsu athletes participated in the study, being randomly divided into three groups of four participants: Control Group (CG); Experimental group 1 (G1), supplementation immediately before the fight and Experimental group 2 (G2), supplementation 30 minutes before the fight. The FPM measurement was performed with the JAMAR® brand analog hydraulic dynamometer in the pre-fight moments and immediately after the fight. The intensity perception of the effort was verified through the adapted Borg scale after the fight. Regarding the findings on muscle strength, there were different outcomes between the groups analyzed.
