Creatine Kinase Levels and Clinical and Functional Parameters in Parajiu-jitsu Athletes
A study testing combat fight in people with Healthy and Deficiency Diseases, run by São Paulo State University at 1 site in Brazil.
Trial summary
Introduction: Evidence indicates that muscle damage caused by exercise can lead to functional, biochemical and clinical damage. Therefore, it is pertinent to perform investigations related to the muscle damage marker, creatine kinase with clinical and functional responses. Read more about this study

About this study
Official title: Correlation Between Creatine Kinase Levels and Clinical and Functional Parameters in the Moments Following the Fight in Parajiu-jitsu Athletes: A Controlled Clinical Trial
Introduction: Evidence indicates that muscle damage caused by exercise can lead to functional, biochemical and clinical damage. Therefore, it is pertinent to perform investigations related to the muscle damage marker, creatine kinase with clinical and functional responses. These outcomes encompass an intrinsic potential for understanding the real magnitude of interpretation of classic signals in athletic environments and monitoring of athletes, contributing to specific actions. Objective: To verify the correlation between clinical signs (pain and perception of recovery), functional (muscular strength) and the behavior of CK levels, in the moments following a simulated fight. METHODS: Six male parajiu-jitsu practitioners (34-44 years) were included in the study. The participants attended the collection site 4 times, with a 24-hour interval between sessions, characterizing the following collection moments: baseline, post-exertion, 24, 48 and 72 hours after the simulated fight. Data on pain (visual analogue scale - EVA), perception of recovery (Likert Scale), muscle strength (Dynamometry) and blood samples for CK analysis were collected. All parameters described were measured at all times of collection. For the analysis of the association between behavior of CK levels, clinical and functional variables, the Odds Ratio test and 95% confidence interval were used. For the gross values, the Pearson test was used according to the normality of the data.
Read the detailed description
Participants will be intentionally allocated into two groups, G1 consisting of professional athletes and G2 consisting of amateur athletes. This division was carried out to guarantee homogeneous stratification between participants with level of conditioning and similar training. The anonymity of the participants will be guaranteed. There will be masking of the participants, investigator and evaluator of the results that were blind to the hypotheses and allocation in groups, adopted in the study. All participants regularly attended the same training center and no sports injuries that might compromise athletic performance will be reported during the survey.

Jiu-jitsu heating with light intensity was used for 5 minutes.

In these cases, the athletes were separated and oriented to return immediately. Thus, maximum effort was advocated as well as, similar time of activity for all
