As with all exercises or sport at this intensity it is almost exclusively dependent on the stores of carbohydrate in the muscle: muscle glycogen (2). This is true quantitatively during one match and is particularly true during multiple match days, such as practice or tournaments (3). With regard to practices over the course of a week, coaches have choices to make regarding the yin-yang of carbohydrate intake and total work during practice. Training every day for 2 hours will require a consumption of 8-10 g carbohydrate/kg body weight (for the 70 kg wrestler, 560 g carbohydrate; 2240 kcals/day of carbohydrate) which is a very large amount; similar to endurance athletes. An alternative approach would be to practice 3 non-consecutive days/week or every other day, in this case only half of the carbohydrate would be needed to consumed every day (70 kg wrestler; 280 g/day or 1120 kcal of carbohydrate/day.) This second approach would appear to be supported by tapering (reduced training volume) research where muscle glycogen is increased (1) and lactate is increased after an improved maximal performance (4,5,6). This approach would also appear prudent for the student-athlete as low muscle glycogen would lead to low blood glucose and quite likely to a reduced performance in the classroom as well as in the gymnasium. Again, it is reducing the training frequency variable that is most important to optimize muscle glycogen concentrations for practices and competitions.","PeriodicalId":387289,"journal":{"name":"International Journal of Wrestling Science","volume":"68 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2013-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122326995","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The purpose of the study was to research the age peculiarities of stress resistance and psycho-emotional states in elite wrestlers. A total of 19 elite athletes (a span of ages), all members of the Ukrainian National Team in Greco-Roman wrestling were examined. The perception and processing of visual information, the balance of the nervous system and psycho-emotional stability were studied. The deterioration of neurodynamic functions in emotionally stressful situations was more evident in older age group compared with the younger age group due to age weakening of the afferent system of information perception, analysis, and processing. Conclusion: The connection between the age of elite athletes and stress resistance to psycho-emotional tension was recorded. In particular, it demonstrated considerable changes in heart rate regulation in the older age group when compared with the younger age group where the optimal reaction of heart rate regulation to psycho emotional tension was observed.","PeriodicalId":387289,"journal":{"name":"International Journal of Wrestling Science","volume":"2016 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2013-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131012813","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The sample of this study consisted of 9 subjects, 8 of whom were cadet beginner wrestlers (between the age of 12–14 years), in addition was one adult international level wrestler. To test whether this gene has the ability to predict the wrestler's level of muscle strength we compared the lengths of the gene under study in the beginners and the international wrestler by using restriction enzymes. The main results indicated that there are 8 enzymes that succeeded in differentiating between the international wrestler and junior wrestlers in the length of this gene, while 4 did not succeed. The results also indicated that the gene ACTN3 (R577X) can predict the expected level of muscle strength of the cadet wrestlers, as there were 2 cadets with a ACTN3 gene length similar to the international level wrestler. The similarity in the constituent amino acids for muscle protein was also observed, along with the existence of a direct relationship between some maximum muscle strength and explosive power tests and the length of ACTN3 gene.","PeriodicalId":387289,"journal":{"name":"International Journal of Wrestling Science","volume":"4 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2013-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128001490","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

High levels of different coordination abilities are very important in wrestling. Most successful competitors have versatile technique, and are able to make use of their skill in various situations during competition. The purpose of this study was to determine the level of movement coordination with relation to a training stage (age categories) as well as determining the dominant direction of rotation. The Starosta Global Movement Coordination Test was used. The wrestlers of the national team were subject to the investigation: the group consisted of 227 male, elite wrestlers, both free and classic styles cadets, juniors and seniors. The investigation was carried out twice, but always in the preparation period. Results: 1. Classic style and free style juniors showed the highest level of movement coordination, 810.25° and 746° respectively. The cadets (classic style) and seniors (free style) achieved the lowest levels. 2. Most wrestlers, except cadets, showed a decrease in performance during the second investigation. 3. Rotation to the left was predominant in tested wrestlers, however in the classic style wrestlers the differences were not statistically significant, while in free style juniors and cadets, the differences were significant.","PeriodicalId":387289,"journal":{"name":"International Journal of Wrestling Science","volume":"20 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2013-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114954213","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Two raters, one of them an expert researcher in performance analysis, and the other an active senior wrestler and national level referee, separately analyzed a sample composed of 2 video-recorded combats per style (N=6) downloaded from FILA's World Senior Championships ‘11 WebTV site, using eleven categories as indicators for classification and to determine the duration of the wrestlers actions in both activity and rest time. Inter-rater reliability tests Cohen's Kappa and Intra-class Correlation Coefficient (ICC) were used as Agreement Measures in order to assess the categorical and duration data. Resulting values were classified as “substantial” for categorical agreement per style and and “almost perfect” for agreement in duration and score-related actions. These results indicate that this new TMA model can be considered reliable when being used by different raters.","PeriodicalId":387289,"journal":{"name":"International Journal of Wrestling Science","volume":"1 2 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2013-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116896104","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Doping is a complicated phenomenon, thus the purpose of this study was to investigate relationships between doping attitudes and other psychological factors. Methods: Fiftyfive competitive elite male wrestlers (Age: 25.63 ± 3.14 yrs; Height: 173.46 ± 4.27 cm) from the Kermanshah and Kurdistan states of Iran were participants in this study. All subjects completed the Performance Enhancement Attitude Scale (PEAS), Sport Multidimensional Perfectionism Scale (MPS), Form V of the Sensation Seeking Scale, Task and Ego Orientation in Sport, Trait Sport Confidence Inventory and the Doping Use Belief questionnaires. Results: Pearson's correlation coefficients showed a significant positive correlation between the PEAS with Doping belief (r=.582, p<.01), Disinhibition (r=.388, p<.01), Perceived Coach Pressure (r=.329, p<.05) and Concern over Mistakes (r=.298, p<.05) and had significant negative correlation with Task orientation in Sport (r=−.363, p<.01). Multiple regression showed the combination of psychological factors significantly contributing to the prediction of Doping Attitude; F (4, 43) = 6.84, p < .001, R2= .33. Conclusion: It is obvious that the most effective approach in the fight against doping is prevention, thus the identification of athletes who score high in the personal characteristics of perfectionism, sensation seeking and goal orientation in sport could be helpful information for coaches and team physicians, in order to detect, monitor and further work with the athletes that may be at higher risk for doping.","PeriodicalId":387289,"journal":{"name":"International Journal of Wrestling Science","volume":"39 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2013-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125501094","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
