Future research related to hormonal changes in official kickboxing competition, female athletes, participant levels, and for different kickboxing styles (full-contact, low-kick, light contact) are needed to support the knowledge in the field. Another study by Ouergui et al. showed that simulated combat is not different to official combat in terms of stress response, with similar values pre- to post-combat to the results of Ouergui et al. . Self-confidence, anger, motivation and competitive anxiety were the mediator variables of hormonal change-competition/outcomes relationship in striking combat sports athletes. Testosterone responses to striking combat sports competitions relative to different moderator variables. Cortisol responses to striking combat sports competitions relative to different moderator variables.
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 .
For instance, hormone analytical method (e.g., Elecsys assays, enzyme-linked immunosorbent assay ELISA, radioimmunoassay RIA or multiplex) and intra/inter-assay coefficient of variation were different in all studies. Second, in the supposed peripheral mechanism, T and C play important roles in mediating training adaptation, with one or more mechanisms involved, such as muscle and motor unit development, behavioural changes, and mobilization of metabolic resources . First, the central mechanism relies on the fact that free C concentrations of subjects negatively correlated with the motor cortex response . In the likelihood intrinsic motivation, individual self-confidence, anger, mental toughness, and competitive anxiety are the psychological variables related to a competitive event. Finally, these data are important for sports psychology and sports science in general to suggest a new area of research in psychobiology. For instance, even though the study of Chiodo et al. showed no relationship using the profile of mood states (POMS) tool, this does not exclude existing relationships that could be demonstrated with other more specific tools.
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.
A combination of "biological" and "psychological" measures can be used to characterize the athlete in terms of attitude and performance. The time of day at which the C and T were measured was found to be an insignificant moderator in the relationship between hormone change and competition. In addition, plasma growth hormone (GH), C, glucose, and lactate concentrations were significantly elevated following non-combat kickboxing (NCKB) sessions, which consisted of 10 min of very light warm-up followed by seven sets of six techniques, 20 s per technique as fast as possible, with 1 min of rest between sets . Indeed, further studies into the dissociation between gender and the mechanisms determining gender differences in competitive settings are strongly recommended.
Research has found that winning doesn't boost T levels alone, it also depends on the part you play. The T-levels of most men plummeted, as expected. In a study conducted by Mehta and colleagues , 64 men were recruited to take part in an unfair competition. Research shows that testosterone increases your ability to overcome defeat. This can have a significant impact on your testosterone level, according to research. Losers were more likely than winners to see their T-levels decrease. The prefrontal cortex of the brain is directly affected by testosterone.
Only two studies (three ESs) aimed at investigating the effect of noradrenaline levels immediately following combat events. Based on two studies’ results (four ESs), alterations in T levels following the two different forms of karate (i.e., kumite and kata) were analysed. Based on two studies’ results (four ESs), alterations in C levels following the two different forms of karate (i.e., kumite and kata) were analysed. Hormonal responses between pre- and post-kickboxing competition (mean ± SD or relative effect %). All studies were cross-sectional with pre- and post-combat hormonal analysis (Table 1, 2, 3). Furthermore, possible mediator variables, such as self-confidence, anger, mood state, and anxiety, have been shown to influence the hormonal stress to competition and were therefore included in the study. Typically, measuring psychological variables, which are also called mediator factors, could help researchers and coaches understand why and how the increase or decrease of stress in the competition was achieved.
The present systematic review and meta-analysis showed that the hormonal response during official combat competition was greater than that in simulated conditions. The measurement of psychological and hormonal parameters offers a unique possibility to achieve a more comprehensive evaluation of the stress responses of the individual in competitive situations. In addition, previous studies suggest the possibility of an intriguing correlation between psychological and biological (i.e., hormonal responses) factors in response to competitive contests 9,24,40. However, compared to adults, fewer data are available in young individuals on the subject of the role of endocrine system status in influencing both athletic performances and the hormonal response to exercise-related stress , while in competition events, no studies in the literature have addressed this topic.
The meta-analyses were performed using Comprehensive Meta-analysis software (Version 2.0, Biostat Inc., Englewood, NJ, USA). Therefore, it would be useful to investigate the effects of these moderator variables on competition events and hormone-changes relationship. Moderator and mediator variables whose hormonal concentrations changed were recorded when applicable. Twenty-seven items were used to determine the Methodological Quality Checklist of each study. Two reviewers (MS and AP) conducted a methodological quality assessment on each included article using the modified Downs and Black scale , which is appropriate for nonrandomized control trials (NRCTs) and case–control study designs. The potentially relevant studies were screened for eligibility by two reviewers (MS and AP) by examining the titles, abstracts and full texts. This controversy may be due to differences in age, gender, and the nature of the competition.
