Athletes, who engage in wrestling, perform weight adjustment before the competitions like all weight loss category sports. For this reason, weight management is a very important factor prior to matches. When the studies on weight loss are examined, it is seen that athletes lose weight in a short time close to the competition. This study aimed to investigate the effects of short-term body weight loss in elite wrestlers on anaerobic performance and reaction time during tournament conditions. Ten experienced international level male wrestlers participated as a volunteer in this study. Participants lost 5% of their body weight within 48 hours, in 72 hours; 1 kg tolerance was given over 5% of body weight. During this process, body composition measurement, Wingate anaerobic performance test (WAnT), Countermovement Jump (CMJ), and visual and auditory reaction tests were conducted. In this study, a randomized crossover design was used and applications lasted four days. Two-way ANOVA with repeated measures was used for statistical analysis. Due to short-term body weight loss in body composition, total body water (TBW) and fat-free mass (FFM) were significantly reduced. In contrast, there was no statistically significant difference in body fat percentage (BF %), visual and auditory reaction time, CMJ and average power (AP). However, there was a significant increase was seen in Peak power (PP) and fatigue index (FI). The results indicate that 5% loss of body weight within 48 hours caused significant changes in body composition and negatively affected the fatigue index. For this reason, athletes who lose weight should avoid rapid weight-loss practices that will cause sudden changes in body composition in order to maintain their athletic performance.

“…Oppliger et al, (2003) observed that 80% of the college wrestlers were interested in dieting, more than 50% fasted and approximately 75% increased their training load to lose weight. Demirkan et al, (2011) also found that although relevant quick weight loss and dehydration in the cadet wrestlers just prior to weighing were followed by quick weight gain between weighing and the competition; there was no improvement in the hydration situation.…”

Weight loss in human body accompanies physical and psychological differences. In this study, it was aimed to see whether acute weight loss (dehydration) affected self-esteem and appearance esteem in the elite wrestlers before competitions. 38 professional wrestlers who had international competition experiences and were required to be in a lower weight class because of having more than the competition weight, participated in the research voluntarily. 1 st measurement 1 week before the competition, 2 nd measurement during the competition morning when class determination was done in accordance with body weight were performed in the participant wrestlers prior to acute weight loss. In addition to the athletes' body weight, body mass index (BMI), "the Rosenberg Self-Esteem Scale" for the determination of their self-esteem levels and "the Appearance Esteem Scale" for the determination of self-esteem associated with appearance were used. The participant wrestlers were professional, they often lost weight before competitions and reached their goal, that's why they had positive feelings, which gave rise to increases in self-esteem and appearance esteem values after weight loss.In conclusion, significant differences were found in body weight, BMI, self-esteem and appearance esteem values before and after weight loss (dehydration) of the wrestlers. A positive uprising was determined in the self-esteem and appearance esteem values after the wrestlers' weight loss. The participant wrestlers were professional, often experienced weight loss before competitions and had targeted weights, that's why they had positively emotional situations, which led to increases in their self-esteem and appearance esteem values.

“…Employment of the methods of complex and systemic analysis, multivariate statistics has allowed to develop adequate mathematical models and to use them for modelling physical state of wrestlers and elaborating differentiated system of estimates of the level of FF and special work capacity according to various key informative and integral indices. It has become an absolutely new approach in the system of biological monitoring of physical state of wrestlers, which is absent in similar studies of other researchers (Iushkov, 2002;Pankov, 2002;Erkan, 2011;Pilianidis et al, 2011;Sbricolli, Bazzucchi, Mario, Marzattinocci, & Felici, 2007). Differentiation of functional fitness estimates of highly skilled combat athletes of different weight categories on the basis of developed model characteristics allows more accurate characterization of their physical state and functional reserves, manifested in the responses to physical load at various stages of annual preparation cycle in different ways.…”

“…Despite numerous publications on organization and provision of scientific-methodological assistance during preparation of highly skilled athletes (Iushkov, 2002;Kraemer, 2004;Rahmani-Nia, Mirzaei, & Nuri, 2007;Rowe, 2015), there is no sufficiently substantiated system of biological monitoring of physical state of combat athletes at different stages of preparation as of today (Iushkov, 2002;Pankov, 2002;Adam, Smaruj, & Tyszkowski, 2011;Erkan, 2011). Moreover, the respective criteria have been insufficiently substantiated, whereas the system of estimates of functional reserves of athletes of different age, sex, skill level, weight category has not been fully differentiated depending on preparation period, individual peculiarities, sports result, ecological and other factors (that is, in an integrated and systemic manner) (Yoon, 2002;Calmet, 2007;Jagiełło, & Kruszewski, 2009).…”

Аbstract.Objective. The objective of the work consisted in substantiating criteria and elaborating differential estimates of functional fitness of highly skilled wrestlers at precompetitive stage of preparation. Material and methods. From 12 to 54 athletes aged 20-28 years, members of the national teams of Ukraine in Greco-Roman and free-style wrestling, and judo participated in studies. Functional fitness and special work capacity of wrestlers were estimated on the basis of the methods of electrocardiography, variation pulsography, pulsometry, gas analysis, physical work capacity testing. Results. The major criteria of wrestlers' functional fitness at rest and in body responses to physical load appeared to be: 1) cardiac function bradycardia and low index of myocardial tension under basal conditions in prone position; 2) high reactivity of cardiovascular system during physical load; 3) economy of physiological system functioning, low tension in regulatory system activity; 4) high level of speed capacities and functional stability of the body of wrestlers during specialized physical loads. The key integrative indices of wrestlers' fitness general structure appeared to be: special work capacity level, general level of functional fitness, mobility of physiological processes, economy, anaerobic power. Developed mathematical models reflect different variants of interrelations and ratios of the key and integral physiological indices with respect to skill level, weight category and the level of athletes' special work capacity. Formalization of these dependences provides more efficient approach to the issue of controlling, modelling and managing functional fitness and special work capacity of wrestlers at the stage of maximal realization of individual capacities. Conclusions. Increase of specific weight of the key integrative functional indices in special work capacity determination along with the enhancement of wrestlers' skill level represents the most significant criterion for improvement of their fitness structure.
