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.","PeriodicalId":126066,"journal":{"name":"Spor Bilimleri Araştırmaları Dergisi","volume":"1995 5","pages":""},"PeriodicalIF":0.0,"publicationDate":"2023-12-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"139160346","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}

In the analysis of the data, t-test, ANOVA, and Linear Regression analysis were used in independent groups. According to the results of the research, it was determined that the majority of women were married, worked as civil servants, did not consume cigarettes and alcohol, paid attention to healthy nutrition, and used pedometer. It was determined that the majority of woman had a normal body mass index (BMI), their total Metabolic Equivalent (MET) levels were at a good level and their conscious awareness levels were at a moderate level. Total MET scores of females in the Black Sea region were significantly higher than women in the Central Anatolia region (p<0.05). It was concluded that the conscious awareness scores of females did not predict BMI and total MET scores (p>0.05). As a result, it can be said that the healthy living habits of female in Türkiye are at a good level, but this cannot be predicted with the level of conscious awareness.","PeriodicalId":126066,"journal":{"name":"Spor Bilimleri Araştırmaları Dergisi","volume":"12 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-09-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115242924","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}

Random sampling method was used to determine the groups, and which would be the control or experimental group. To assess social skills, Social Skills Assessment Scale (SSAS) developed by Akçamete and Avcıoğlu (2005) was scored by each participant's primary school teachers. Observation forms prepared by the researchers were used to evaluate movement skills. Measurements were taken twice before and after 8 weeks of practice. Mann Whitney U test was used to compare the experimental and control groups data, Wilcoxon Signed Rank was used in the pre-test-post-test difference comparisons of the groups. According to the analysis results, in terms of social skills, the difference scores of the peer education were found to be statistically significant (p<.050) while the difference scores of the control group were statistically insignificant (p>.050). According to the results of the analysis of movement development specific to gymnastic, significant difference was found in both groups (p< .050). As a result, it has been seen that both the peer teaching model and the traditional method support movement development in gymnastics education.

It has also become an indispensable tool for countries to emphasise their unique cultures and to promote themselves. Based on these points, in football, which has become an industry and a source of commercial income with the passing of time, it has been important to follow the competitions meticulously, to examine every detail, and to minimise the errors to the minimum level. Especially in big organisations, this situation is more prominent. In this regard, the video assistant referee system, which is a product of teamwork, has been developed through digital platforms to assist and support the referee during the match. The aim of this study is to reveal the effect of the VAR system on the matches played in the 2022 FIFA World Cup and UEFA Women's EURO 2022. In the study, 64 matches played in the 2022 FIFA World Cup, 31 matches played in the UEFA Women's EURO 2022 and 95 matches in total were analysed. VAR decisions in the tournaments were evaluated separately on 11 parameters (accuracy of the goal awarded, accuracy of the goal not awarded, goal cancellation, goal awarded, accuracy of the penalty awarded, accuracy of the penalty not awarded, penalty cancellation, penalty awarded, red card awarded, red card cancelled and other). The data were analysed in SPSS 25.0 package program and descriptive statistics, percentage and frequency values were used in the analysis. According to the results obtained, it was determined that VAR had a direct effect on the 2022 World Cup only in some of the group matches; in the UEFA Women's EURO 2022, in some group matches and in the France Netherlands quarter-final match. As a result, it can be said that although the VAR system faced some reactions when it was first used, it contributed to the accuracy and reliability of the decisions made in the match and the tournament or league was shaped in line with the results that the teams deserved.","PeriodicalId":126066,"journal":{"name":"Spor Bilimleri Araştırmaları Dergisi","volume":"30 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-08-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"134173618","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}
