Study on the Polymorphic Loci of Explosive Strength-Related Genes in Elite Wrestlers.

This investigation aimed to explore the relationship between Chinese elite wrestlers and the polymorphic loci of explosive strength genes, and to further explore the feasibility of its application to athlete selection. The snapshot technique was used to resolve the polymorphic loci of explosive power genes in the wrestler group (59 elite wrestlers) and the control group (180 ordinary college students), and to analyze the genotype frequencies and allele frequencies of each group. A chi-square test was performed on the genotype and allele distribution data of each group to analyze the loci of explosive power genes that were associated with elite wrestlers. The loci that had an association with elite wrestlers were combined with the genotyping data, and the dominance ratios of the genotypes were calculated using the chi-square test to determine the dominant genotypes associated with elite wrestlers. The VDR gene rs2228570 locus exhibited statistically significant differences in genotype and allele distributions between elite wrestlers and the general population (p < 0.01). At the rs2228570 locus of the VDR gene, the difference between the CC genotype and other genotypes was statistically significant (p < 0.05). The rs2228570 locus of the VDR gene was identified as the locus associated with Chinese elite wrestlers. The polymorphism of the VDR gene can be used as a biomarker for Chinese wrestlers, and the CC genotype can be used as a molecular marker for the selection of Chinese elite athletes in this sport. However, expanding the sample size of elite athletes is necessary to further validate the scientific validity and feasibility of these findings.

THE INFLUENCE OF CHANGES IN COMPETITION RULES ON TACTICS OF WEIGHT CATEGORY CHOICE IN WRESTLING

The article presents the types and specifics of tactics of the weight category choice in women’s, freestyle and Greco-Roman wrestling. In modern scientific papers participation tactics of athletes in the competition system is covered fragmentally. Moreover, tactics of weight category choice is not described at all. We analyzed the dynamics of performances and results of 72 elite wrestlers who won gold, silver and bronze medals at the Games of XXXI Olympiad 2016 in Rio de Janeiro in different weight categories (four athletes in each one). In general, we compared the results of 24 women, 24 freestyle and 24 Greco-Roman wrestlers. There were discovered eight types of tactics which athletes used during four seasons in 2013–2016 Olympic cycle. Some types provided performances only in one Olympic weight category, while others were connected with participation in tournaments in two or even three weight categories during the same season. In all cases elite wrestlers used one weight category (mainly an Olympic one) as prior, while one or two weight categories were considered as additional. We established that the choice of the particular weight category depended on the specifics of the Olympic qualification system-2016, the prospects of obtaining the Olympic quota place in the International Qualification Tournaments and the results demonstrated at official international events in various weight categories. It was also discovered that in 2013 and 2016 the most popular was a tactics that involved performances in one prior Olympic weight category (70.83% of wrestlers used it). In 2014 and 2015 some athletes (1.39–11.11%) performed in the prior weight category and used one or two of them as additional. The largest number of tactics was used by representatives of women’s and freestyle wrestling as the upper limits of weight categories were changed more than in Greco-Roman wrestling.

Nutritional knowledge, eating habits, factors affecting muscle damage, and antioxidant enzyme levels of Korean wrestlers.

The aim in this study was to investigate the diet and nutritional knowledge of elite Korean wrestlers and verify the differences in their exercise performance , muscle damage indicators, and antioxidant enzyme levels according to wrestler level. A 7-day dietary and nutrition knowledge survey was administered to 30 adult male elite wrestlers (national team: n=11; professional team: n=19). The Wingate test was conducted for 60 seconds to analyze muscle damage indicators and antioxidant levels. Blood and blood lactate concentration analyses were performed four times; the statistical significance level of all data was p<0.05. Significant differences were found in general nutrition knowledge questionnaire (GNKQ) scores (p=0.043), diet (p=0.001), anaerobic performance (p=0.001), muscle damage indicators (p=0.026), antioxidant levels, and blood lactic acid concentrations (30 min after exercise, p=0.007; 90 min after exercise, p=0.038) between the national and the professional groups. To the findings confirm the relationship between the differences in diet, nutrition, and motor function for wrestlers of different expertise levels. In a follow-up, a comprehensive study on nutrition knowledge, athlete training , and weight loss is needed that considers a wider scope of subjects and analyzes additional variables.

Factors structure of psychological readiness in elite wrestlers men and women

The article examines the factor structure of the psychological readiness of highly qualified wrestlers. 24 highly qualified athletes specializing in women's wrestling and 33 highly qualified athletes specializing in freestyle wrestling were examined. All athletes are members of national teams of Ukraine. Consent was obtained from all athletes to participate in research and to use the results for scientific purposes. The psycho-emotional state (according to Lüscher's color test), the state of neurodynamic functions (balance and mobility of nervous processes) and the state of cognitive functions (assessment of non-verbal and verbal intelligence, working memory, logical and analytical thinking and the level of manifestation of stress resistance) were investigated using hardware- software computer complex "Multipsychometer - 05".&#x0D; It is shown that the psychological readiness of highly qualified wrestlers consists of five factors: perception of external information; mental state; the quality and speed of processing non-verbal information and making an optimal decision. Among highly qualified wrestlers, five factors ensuring psychological readiness were also found: perception of external information; mental state; making the optimal decision; speed of perception and level of stress resistance. According to the research results, it can be concluded that in order to optimize the psychological readiness of highly qualified wrestlers, it is necessary to have an appropriate level of the state of the system of perception, processing of external information and making an optimal decision. Accordingly, the optimization of psychological readiness in highly qualified wrestlers is ensured by the ability to make optimal decisions with different types of perception and a high level of stress resistance.

Changes in Response Time in Elite Taekwon-Do Athletes and Wrestlers Resulting From Led Lighting Training

Abstract Introduction. Fighting effectiveness of combat sports athletes depends, among other factors, on response time. Athletes must react swiftly to various actions of their opponents during the combat. Understanding the determinants of response time can provide valuable insights and optimize the sports training process. The aim of this study was to determine the influence of Led Lighting Training (LLT) on response time of athletes representing extremely different combat sports. Material and Methods. Elite taekwon-do athletes aged 26.67 ± 7.79 years with training experience of 13.67 ± 6.75 years, and elite wrestlers aged 26.0 ± 3.74 years with training experience of 13.0 ± 3.74 years, participated in the study. Each participant performed a 6-minute physical exertion requiring concentration and proper decision-making as part of LLT. It consisted of three two-minute motor tasks performed on Batak Lite. Response time was recorded during the exercise, with one-minute breaks between motor tasks. Results. Among taekwon-do athletes, the lowest level of response was noted during the first LLT task, whereas the highest was observed in the third task. Response time significantly improved with time of exertion among taekwon-do athletes, while it remained similar among wrestlers after 2, 4, and 6 minutes of the test. Only in the first round did taekwon-do athletes and wrestlers significantly differ in response time (p = 0.0025). Response time and training experience did not reveal a significant correlation. Conclusions. The specificity of training, which is determined by the specificity of combat, does not differentiate elite taekwon-do athletes and wrestlers based on their response abilities. Taekwon-do athletes should control the type and duration of warm-up exercises before combat.

The Investigation of the Effects of Short-Term Body Weight Loss on Elite Wrestlers on Anaerobic Performance and Reaction Time in Tournament Conditions

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.

Особливості прояву психоемоційного стану висококваліфікованих борців із урахуванням статевого диморфізму

Purpose: the manifestation of psycho-emotional state in elite wrestlers with taking into account of sexually dimorphism. Material and methods. 24 elite females athletes and 33 elite males athletes specializing in freestyle wrestling were examined. All athletes were members of the Ukrainian National Team. Mental states were studied using the Luscher test. Stress resistance was studied using the «Stress test» method. All tests used, including the hardware-software complex «Multipsychometr-05». Results: based on the analysis of scientific and methodological literature, it was determined that modern sports wrestling is characterized by a high level of physical and psycho-emotional stress of the athlete in the conditions of competitive activity, and the study of the psycho-emotional state is an important issue for building a training system. The presence of sexual dimorphism with the manifestation of a psycho-emotional state in elite wrestlers has been established. It has been found that due to mental anxiety, male wrestlers have higher values of mental fatigue and internal discomfort compared to female wrestlers. This fact indicates a connection between anxiety as a pre-stress condition that causes fatigue and mental discomfort. At the same time, a higher level of stress resistance was found in men compared to women. The results indicate that a higher level of stress resistance in men is due to a slower impulsivity. In women, a decrease in stress resistance is compensated by an increase in impulsivity. The presence of lower absolute values of the vegetative coefficient in women compared to men was revealed, which indicates a reduced level of tension of vegetative regulation, and, above all, activation of the sympathetic link of the autonomic nervous system. Conclusions. The presence of sexual dimorphism in the manifestation of the psychoemotional state among highly skilled wrestlers has been established. It was found that the presence of mental fatigue and anxiety in male wrestlers leads to emotional discomfort. A higher level of stress resistance was found in male wrestlers compared to female wrestlers. Stress resistance is formed in women by adaptive behavior, tension of the autonomic nervous system regulation and the balance of emotions. In men, stress resistance is ensured by mental focus. Keywords: wrestling, highly skilled, sexual dimorphism, psycho-emotional state, stress resistance.

The Effect of 8 Weeks Preparatory Training Program on Body Composition and Blood Parameters in Elite Wrestlers

The aim of this study is to evaluate the effects of an 8-week training program applied during the preparatory period of elite-level wrestlers on blood parameters and body composition. This study involved the voluntary participation of 10 Greco-Roman wrestlers competing at the national team level and achieving rankings in international tournaments. The participants had an average age of 22.00 ± 3.2 years, an average height of 172.00 ± 8.4 cm, and an average weight of 80.50 ± 11.9 kg. These wrestlers had approximately 12 years of wrestling experience. An 8-week preparatory training program, prepared by experts and coaches, was implemented for participant wrestlers. This training program was applied at the national team level and in the adult category. It was carried out following a 20-day active rest period during the offseason. The following tests and measurements were conducted at the beginning and end of the training program. The data obtained were statistically analyzed using SPSS version 10.0. The mean values and standard deviations of the measured parameters for all participants were calculated. The paired-sample t-test was applied to identify differences between pre and post 8-week preparatory training program. When the participants' blood lipid values were examined, no significant difference was observed in HGB and HCT values between the pre-test and post-test, while RBC and WBC values showed a statistically significant increase (p0.05). When the participants' body composition values were examined, a significant decrease was observed in body fat percentage (BFP) and body fat mass (BFM), while there was a significant increase in lean body mass (LBM) (p0.05). In conclusion, it has been determined that the 8-week preparatory training program has positive effects on weight, body fat percentage, lean body mass, MaxVo2, strength, and immune health.Keywords: Body Composition, Hematological Parameters, Training Program

Coaches’ Perspectives about the Reasons behind Dropping Out of Sports in Wrestlers

It has been known that amateur or professional athletes quit competing because of personal and socio-economic reasons such as lack of financial, technical, or family support, and lack of motivation for a future career. Especially, it has been common in Turkish wrestling that many elite wrestlers quit competing at an early age. This research aims to determine the reasons why wrestlers quit the sport, according to coaches. A qualitative research method was used to conduct the study. The research population included 293 volunteer coaches who were active in sports clubs in fifty-one different cities in Turkey. Participating coaches consist of different experience levels, from beginner coaches to elite-level national head coaches. While descriptive statistics was used to determine the characteristics of the participants, the data was done through content analysis. The research data were obtained with four open-ended questions that were asked of the coaches. After the interview, the opinions of the coaches were written down based on the answers given to the questions. In this study, an example of the question, “Did any of your athletes quit wrestling?” was asked of 293 wrestling coaches. When the coaches were asked, “If your answer is yes, why do you think your athletes quit wrestling?” 173 (59.04%) out of 293 coaches stated that they quit wrestling due to future anxiety, 70 (23.89%) family, 30 (10.23%) disability, 17(5.80%) the coach, and 3(1.02%) friends. According to coaches, the main reason that wrestlers drop out of the sport is the concern about the future.

Elit Güreşçilerde Spor Yaralanma Öyküsü ve Spor Yaralanma Kaygı Düzeylerinin Araştırılması: Betimsel Araştırma

Objective: The purpose of the study was to investigate the sports injury history that occurred during the competition and the training, and anxiety of sports injury in elite wrestlers. Material and Methods: This study was conducted a total of 172 who young wrestlers including 72 females (age: 19±0.85 years; height: 167.83±4.18 cm; body mass: 67±9.58 kg) and 100 males (age: 19±0.83 years; height: 176.92±7.91 cm; body mass: 73±13.32 kg). Ethics committee approval was obtained before the study. In this study, as a data collection tool was used the Sports Injury Anxiety Scale and athlete information form including training experience, wrestling style, the environment in which the injury occurred, rapid weight loss, injured region, etc. As statistical analysis one-way ANOVA test was used for independent groups and Pearson correlation. Results: The study results demonstrated that female wrestlers had higher injury rates including shoulder and elbow and forearm compared to male wrestlers and male freestyle wrestlers had higher anxiety levels for experiencing pain and re-injury anxiety levels compared to female wrestlers (p<0.05). It was found that the rapid weight loss was performed at the rate of 98.6% and 85% in female and male wrestlers respectively. There was a weak negative correlation was seen between the number of weight loss and the experiencing pain (p<0.05). Conclusion: These results confirmed that freestyle wrestlers experienced the anxiety level more than female and Greco-Roman wrestlers.

The Relationship Between Anaerobic Power, Back Strength and Balance in Elite Wrestlers

The aim of this study is to examine the relationships between anaerobic power, back strength and dynamic balance, which play an important role in wrestler performance. 14 male freestyle elite wrestlers (age = 19.07 ± 0.99 years, height = 1.70 ± 0.04 m, body weight = 74.67 ± 8.48 kg, BMI = 25.57 ± 2.31 kg/m2) voluntarily participated in the study. Anaerobic power, back strength and dynamic balance measurements of the participants were taken. Pearson Correlation test was performed to determine the relationship between these features. A statistically significant positive correlation was found between anaerobic power and back strength, between back strength and right and left leg balance, between left leg balance and right leg balance. As a result, it can be said that back strength is effective on dynamic balance in wrestlers and anaerobic power affects back strength.

Prevalence of rapid weight loss in Olympic style wrestlers.

ABSTRACTBackgroundThe methodology applied for rapid weight loss (RWL) among elite wrestlers is quite unexplored. Therefore, the aim of this study was to analyze the prevalence of sources of influence and methods used for RWL and to determine the differences between wrestling styles.MethodsA total of 229 wrestlers who competed at the World Championship held in Belgrade, Serbia, participated in this research. All respondents completed a questionnaire designed to evaluate RWL patterns in combat athletes. Participants were classified according to wrestling style: Greco-Roman, freestyle, and women wrestling.ResultsSixty-nine percent of wrestlers had previously lost weight to compete. Most respondents start losing weight approximately seven days before a competition. Athletes reported that they commonly reduced 3.84 ± 2.82 kg to reach the target weight. The wrestling coach represents the most influential person in terms of RWL strategies, while nutritionists and physicians have the least impact on the weight-cutting process. Regarding the methods applied, differences between all the three styles were found in the following variables: training in a heated room, restricting fluid ingestion, training in plastic suits, gradual dieting, increased exercise, diet pills, and sauna. The most frequently used techniques were increased exercise, gradual dieting, training in a heated room, and sauna for all competitors. Diet pills, diuretics, laxatives, and vomiting were the least implemented methods.ConclusionsThe obtained results suggest that most wrestlers practice RWL despite the harmful health effects. The education of wrestling coaches is necessary in order to control and decrease the negative impact of RWL.

Isokinetic muscle strength cannot be related to the odds ratio of musculoskeletal injuries in young elite wrestlers

BackgroundWrestling is considered one of the oldest sports in the world. There is a high rate of injuries in Wrestling. To prevent injuries, it is necessary to identify the risk factors. Despite the functional importance of strength in wrestling, few studies have investigated the relationship between isokinetic strength and the rate of injuries in the sport.ObjectivesThe objective of the present study was to investigate the relationship between the isokinetic strength of elite wrestlers and the rate of injuries prospectively.MethodA total of 72 young wrestlers with at least 2 years of experience in the Tehran Wrestling Premier League participated in this study. Before the start of the competition season, the isokinetic strength of flexor and extensor muscles of the knee and shoulder were measured at different velocities by an isokinetic dynamometer. The injuries and training hours of these wrestlers were then recorded for nine months.ResultsThe study results showed no significant relationship between isokinetic strength of flexor and extensor muscles of the knee or shoulder at different angular speeds of 60, 180, and 300°/s. There was neither significant between the ratio of the strength flexor/extensor for knee and/or shoulder in young elite wrestlers with injuries.ConclusionIsokinetic strength of lower and upper limb muscles alone cannot predict wrestlers' injuries. Therefore, the use of these tests is not recommended to evaluate the risk of injury in this population.

Autonomic rhythm regulation of elite wrestlers with different dominance of brain hemisphere

The results of a study of the autonomous regulation of the heart rate in elite wrestlers with different dominance of the cerebral hemispheres were present in the manuscript 23 elite wrestlers. Were examined members of the National Team of Ukraine in Greco-Roman wrestling, aged 22-34 years-old. A body composition monitor "Omron BF511" and a computer electrocardiograph "Fazagraf" were used. It was revealed that elite wrestlers with a dominance of the right hemisphere have more intense regulation of the heart rhythm compared to wrestlers with a dominance of the left hemisphere of the brain. With an increase in the tension of the system of autonomous regulation of the heart rhythm in wrestlers with the dominance of the right hemisphere of the brain, the activation of the central and sympathetic division of regulation occurs. For the purpose of a more effective preparation process and in the development of individual training programs for elite wrestlers, it is necessary to determine the dominance of the cerebral hemispheres.

Body Composition and Heart Rhythm Variability in Elite Wrestlers

The aim of the research was to study the body composition and heart rhythm variability in elite wrestlers. In the study we used: Omron BF511 body composition monitor, we obtained and analyzed data on the body composition of 8 highly qualified athletes, members of the Ukrainian national team in Greco-Roman wrestling in 5 weight cate- gories. 67 kg - 1 person, 72 kg - 1 person, 77 kg - 3 people, 87 kg - 2 people and 97 kg - 1 person. Vegetative regula- tion was assessed according to the indicators of statistical and spectral analysis of heart rhythm variability. For this purpose, we used a portable electrocardiograph with finger electrodes for an integral assessment of the functional state of the cardiovascular system "Fazagraf". The parameters of autonomic regulation and the results of spectral analysis in athletes were recorded. As a result of the study, it was found that the indicators of the body composition of the studied athletes have differences, but most of them correspond to the norm according to the Omron Health- care rating scales. It was revealed that the hemodynamic supply of the body in highly qualified athletes occurs at a higher tension of the mechanisms of regulation of cardiac activity. Studies have shown that a high percentage of muscle mass is consistent with the activation of parasympathetic influences on the sinus node of the heart at rest state, which reflects the result of adaptive restructuring of the body during the training process.

The effect of 8-weeks wrestling training on unilateral muscle imbalances

Background and Study Aim. This study aimed to investigate the effect of 8-weeks of wrestling training on unilateral muscle imbalances.&#x0D; Material and Methods. Eight male elite Greco-Roman wrestlers (wrestling group) (age 21.25±2.7 years, height 176.6±6.8 cm, body weight 81.00±9.3 kg) and seven recreationally active male (control group) (age 21.3±3.2 years, height 173.6±4.7 cm, body weight 67.3±5.3 kg) voluntarily participated in the study. Both group participants were students in the Selcuk university in the period of study. Wrestlers were in the off-season before the training period of 10 weeks. Before and after the 8-weeks training period, wrestling and control groups were tested for isokinetic torque measurement. In the training period, the wrestling group carried out only wrestling training without specific strength training. In this period the control group did not involve in any exercise.&#x0D; Results. In the wrestling group, all quadriceps torque parameters significantly increased for both legs but the torque parameters of the hamstring did not change, except the average torque of the left leg. The peak and average torque of the H/Q (Hamstring/quadriceps) significantly decreased after training periods for right leg in the wrestling group. No parameters significantly changed in the control group.&#x0D; Conclusions. Specific hamstring strength exercises can be put in training programs to avoid from a possible knee injury.

Effects of an overnight high-carbohydrate meal on muscle glycogen after rapid weight loss in male collegiate wrestlers

BackgroundSevere rapid weight loss (RWL) induces a decrease in muscle glycogen (mGly). Nevertheless, adequate carbohydrate intake after RWL has not been reported to optimize muscle glycogen following a weigh-in the evening until a wrestling tournament morning. The purpose of this study was to investigate the effect of an overnight high-carbohydrate recovery meal of 7.1 g kg−1 following RWL on mGly concentration.MethodsTen male elite wrestlers lost 6% of their body mass within 53 h and then subsequently ate three meals, within 5 h, containing total of 7.1 g kg−1 of carbohydrates. mGly was measured by 13C-magnetic resonance spectroscopy before (BL) and after RWL (R0) at 2 h (R2), 4 h (R4), and 13 h (R13) after initiating the meal. Body composition, muscle cross-sectional area, and blood and urine samples were collected at BL, R0, and R13.ResultsBody mass decreased by 4.6 ± 0.6 kg (p < 0.05) and did not recover to BL levels in R13 (− 1.7 ± 0.6 kg, p < 0.05). Likewise, mGly by 36.5% ± 10.0% (p < 0.05) and then did not reach BL levels by R13 (p < 0.05).ConclusionA high-carbohydrate meal of 7.1 g kg−1 after 6% RWL was not sufficient to recover mGly during a 13 h recovery phase. Participating in high-intensity wrestling matches with an mGly concentration below normal levels is maybe undesirable.

The effect of acute dehydration on agility, quickness and balance performance in elite wrestlers

Background and Study Aim. The aim of this study was to investigate the effect of acute dehydration on agility, quickness and balance performance in elite wrestlers. Material and Methods. A total of 12 male elite wrestlers, who were student at Selçuk University Faculty of Sport Sciences, whose mean age was 21.58±1.44 years, the mean height of 176.67±5.87 cm, mean body weight of 74.25±17.79 kg, and the mean age of sports 8.92±1,44 years have participated the study voluntarily. After taking the height measurement of the wrestlers participating in the study, their masses were weighted before the training; and body mass index, body fat percentage, muscle mass, and total body fluid were taken with Tanita Bc 730 and agility, quickness (5 m) and balance performance tests were performed. Then, by limiting the fluid intake of the athletes, after losing weight by training, the same tests that were applied before the training applied to the athletes after the training. The study was conducted in accordance with the pre-test and post-test model. T test was used for agility performance measurement of the athletes and 5 m test was used for quickness performance. Dominant foot was determined for balance test and measurement was made via Biodex Balance System. Balance measurements were performed eyes open (EO) and eyes closed (EC), overall stability index (OSI). Results. In this study, body weight, body mass index, total body fluid, agility, quickness and balance with eyes open mean values were found to be statistically significant (p&lt;0.05), and muscle mass, body fat percentage, balance with eyes closed found not to be statistically significant (p&gt; 0.05). Conclusions. It is believed that acute dehydration negatively affects agility, quickness and balance performances in wrestlers.
