Popis Background and Study Aim The relationship between combat sports and aggression has begun to be focused by some researchers. While Wann & Branscombe [1] consider combat sports (e.g. boxing) as typical examples of aggressive sports, other authors [2–4] assume that training of combat sports could lead to a reduction of aggressiveness among the trainees. Self-report research tool Buss-Perry Aggression Questionnaire (BPAQ) was involved in discovering the difference in aggressivenes level among players of non-combative (baseball) and combative sports (Brazilian jiu-jitsu). Material and Methods The research sample involves N=60 male sportsman from the Czech Republic divided into two subgroups (N=30 baseball players in the age 26.80 ± 4.75 and N=30 Brazilian jiu-jitsu players in the age 26.47 ± 4.92). Descriptive statistics, T-test and size effect evaluated by Cohen´s d were used for the analysis. Results Results showed that there are no statistically significant differences in aggressiveness level between samples A (baseball) and B (Brazilian jiu-jitsu) on the level of statistical significance 0.05 %. According to Cohen´s d interpretation, we can consider the significant difference between A and B samples in the verbal aggression factor (d = -0.38). Conclusions According to BPAQ methodology, there is no statistically significant difference in aggressiveness level of baseball and Brazilian jiu-jitsu players in all four partial factors (physical aggression, verbal aggression, anger, hostility). The size effect is significant in the verbal aggression factor (d= -0.38). An increase of participants number could enhance the validity and reliability of research. We highly recommended continuing research for revealing the relationships between combat systems training and aggressiveness.
