In the same contest, Capranica et al. showed that sA-A and sC increased post-bout, with lower pre- and post-bout values than those of Chiodo et al. . A typical taekwondo competition contains three 2 min rounds with a 1 min recovery in-between . The sC values recorded at post-combat 2 would be considered the highest compared to those recorded at post-combat 1. We did not use this study in the quantitative synthesis because the authors presented the same data in the study of Ouergui et al. . The I2 measure of inconsistency was used to examine between-study variability; values of 25, 50 and 75% represent low, moderate and high statistical heterogeneity, respectively . Hormonal measurements methods using blood, urine or saliva samples were included in the present study.
Whereas, to date, limited studies on this topic were reported, researchers are encouraged to examine the psychological mechanisms of the hormonal response-competitive situation/outcome relationship. This suggests that humans’ hormonal response to competition is not a direct consequence of winning and losing but rather is mediated by complex psychological processes that could even contribute to the competition outcome. However, some psychological variables (e.g., mental toughness, mood state) have been strongly linked with optimal performance and outcome in combat sports 10,48,49. Furthermore, psychobiological studies of martial arts can increase our understanding of the "power of mind" to modulate neurochemical responses.
"These data suggest that winning wrestlers may use a different regulatory mechanism for their acute testosterone responses than losers," according to Dr. Fry and co-authors. Higher testosterone levels amplify this trait. The T-levels of losers dropped not only after the competition but at the start of the following match as well. Pre-frontal cortex is more influenced by testosterone levels. Furthermore, the link between psychological variables and hormonal response seems to be a very important area of future research. This difference may be due to (a) the importance of the competition for the athlete, (b) blood compared with salivary hormonal sample collection, and (c) the type of martial art concerned.
Accordingly, Mazur and Booth found that while men showed a rise in testosterone levels prior to a contest, there was no corresponding rise for women. A previous review by Kraemer and Ratamess showed that age and/or maturity are mediator variables of the resistance training-endocrine response relationship. For instance, age significantly affected the relationship between T levels and the competition situation. An analysis of available data in judo athletes showed great variability in hormonal response, with T and C concentrations increasing or decreasing in winners or losers, respectively .
These data provide sufficient ground to conclude that there are no fundamental differences in the physical capacity among athletes from various combat sports. The requirements for sports with marking techniques, with karate and partly taekwondo being examples, are different than for a real physical contact fight (e.g., judo, kick-boxing, and wrestling). So, in sports which involve kata and faking techniques, the athletes show lower preparedness to a real physical struggle with an opponent than do athletes in other combat sport disciplines . Most karate and taekwondo competition involves predesigned attack, defense, and counterattack (kata) demonstration forms.
