This is most likely due to a too little weight loss in our athletes (−3.9%) as compared with the one described elsewhere (−10.0% body mass) ((Coswig, Fukuda & Del Vecchio, 2015). An imbalance between physical training and rest periods results in reduced physical capacity, severe fatigue, and even overtraining (Pankanin, 2018). Changes in testosterone concentrations due to the implemented training loads are most likely related to the inhibition of the hypothalamic-pituitary-adrenal axis.
This hormone is what spurs the transition of a boy into a man during puberty. With this hormone, an athlete can work out harder than he did before, recover more quickly, and develop a physique with more muscle and less fat. Due to its role in helping people build muscle mass, it’s a steroid hormone, in effect. Males and females both have their own primary sex hormones that are responsible for their unique characteristics. Additionally, factors like water quality and sunlight exposure play a role in maintaining hormonal health.
Disruptions in sleep patterns or insufficient sleep can lead to lower testosterone levels, which in turn affect muscle growth, recovery, and overall athletic performance. Their research revealed that just one week of sleep restriction to 5 hours per night led to a 10-15% decrease in daytime testosterone levels in young, healthy men. Anabolic steroids remain the most important and effective way for UFC and MMA fighters to increase their testosterone for optimal performance. These synthetic derivatives of testosterone are designed to enhance muscle mass, strength, and reduce recovery times by significantly elevating the body’s testosterone levels. The decline in hormone levels, particularly testosterone, cannot be attributed solely to the natural aging process. Can we, as dedicated martial artists, take steps to maintain or even boost our testosterone levels to continue excelling in our discipline while safeguarding our health? From a psychological perspective, these factors can indirectly influence testosterone levels as well.
In light of the results obtained, the hormonal axis analyzed here has been proven to be as important in the metabolic response to exercise as it is in endurance sports with the dynamic component prevailing. The type of exercise in numerous combat sports involves short intervals (short breaks between attacks). In such sports, what matters more than success in a competition is discipline, educational effect, physical fitness, and self-confidence. The available literature reports that Olympic-level combat athletes generally show higher aggression indices than those performing at a lower level . Most karate and taekwondo competition involves predesigned attack, defense, and counterattack (kata) demonstration forms. Although all combat sport disciplines have a common origin, they remain different with regard to the rules of the fight, its dynamics, and requirements posed on the athletes.
A decrease in the blood concentration of this hormone indicates processes of long-term adaptation to anaerobic power loads in athletes practicing fitness (Chernozub, 2013). An essential element of sports training is the formation of grappling skills (punches, twists, throwing techniques using the legs) and submission on the ground (Kirk, Hurst & Atkins, 2015; Tota et al., 2019a). They demonstrated that similar values of biochemical markers depicting the level of muscle damage could be observed after sparring and after competition. Moreover, our results confirm that MMA is a high-intensity sport and that the concentrations of biomarkers indicating the degree of muscle cell damage in athletes remain high even 24 h after the competition.
The presented results should help better comprehend such training-related processes as fatigue, recovery, and adaptation. To our knowledge, this is one of the few studies to employ such an extensive observation and analysis of biochemical indicators. The plasma volume differences between the assessments obtained 1 h and 24 h after the competition amounted to 5.63 ±4.83% (Table 3).
The results showed a significant decrease in T and free androgen index in male athletes with no effect on sex-hormone-binding proteins, as well as a decrease in the IGF-I levels in both genders. During simulated karate, Benedini et al. compared the pre- and post-3 min hormonal response to kata and kumite forms. Forest plot of insulin-like growth factor 1 changes induced by striking combat sports competitions. Only two studies (three ESs) aimed at investigating the effect of noradrenaline levels immediately following combat events.
