ASSESSMENT OF THE MUSCLE DAMAGE MARKERS FOLLOWING SIMULATED PARA JIU-JITSU COMBAT IN ELITE AMPUTEE ATHLETES

The objective was to evaluate markers of muscle damage (CK, lactate, and LDH) after combat. This study followed a multiple-case study design. The research focused on three elite Para Jiu-Jitsu athletes aged 40-50 years with transfemoral amputations. Pre-combat and post-combat blood samples were collected from the participants, and the lactate, LDH, and CK levels were analyzed. All markers increased after the fight in all participants (lactate - Δ% mean = 878%; LDH - Δ% mean = 23.6%; CPK - % mean = 124.1%; and CPK-MB - % mean = 555.4). Lactate levels after the fight were similar among participants and within the reference values, although with a significant increase, as were CPK and LDH values, except in participant 2, who exceeded the reference values ​​for CPK (765 U/L) after the fight. Based on the analyses implemented, it is clear that parasports jiu-jitsu reflects high acute metabolic demand.
