The first part of the research consisted of 102 children aged 14-15 years with no previous experience in Tennis. There were held 12 lessons for the first two strokes (forehand and backhand) and then 8 lessons for the service to students in 6 classes of third -grade Junior High School students in 2 different schools. The sample members were divided into two groups (experimental and control), and the data were processed in the statistical program IBM SPSS 24 using the t-test for independent samples before and after the intervention with a significance level of (p <.05).  The survey showed that the performance of the participants was improved in tennis in the forehand, backhand and service in both teams (especially in the E.G.), after finding a statistically significant difference in the scores (increasing the mean of consecutive strokes and accuracy). In the second part of the research, the sample consisted of 408 students aged 12-15, 204 students in High Schools of the Municipalities of Tanagra and Chalkida, as well as 204 from tennis clubs of the Municipalities of Larissa, Chalkida and Thebes. A detailed plan of one hour reciprocal teaching was applied to the 3 main aforementioned tennis strokes and at the end the participants were given as a measuring tool, anonymously and confidentially the questionnaire of Intrinsic Motivation Inventory (IMI) by McAuley et al. (1989). Data processing in IBM SPSS 24 via one-way variance analysis (One-Way Anova) gave the results: There is a statistically significant difference between the first-grade and second-grade High School classes in the effort which is due to a systematic factor and the pleasure, the perceived ability, the pressure, the attitude / opinion towards tennis, the intention to try tennis and the physical activity are influenced by the highest level of education completed by the father.","PeriodicalId":36509,"journal":{"name":"Central European Journal of Sport Sciences and Medicine","volume":"1 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2023-03-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"85330849","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 addition, we examine if the anaerobic exercise index calculated by only GPS data presents this evaluation to examine its validity. In the laboratory, the oxygen uptake (V̇O2) matched with moving speed was identified during an incremental exercise test on the treadmill, and the ventilatory (anaerobic) threshold was also analysed to identify individual aerobic and anaerobic exercise intensities. Using these laboratory data, time-to-time changes in individual relative running intensity (aerobic and anaerobic) were visualised from individual GPS data during a football game, and an individual’s sprint output (ability) during the game was evaluated. An index of running intensity and the percentage of anaerobic exercise over the game provided by the GPS software (equivalent distance index [%EDI] and anaerobic index [AI]) did not present the actual individual exercise intensity (ICC(2,1), absolute agreement=−0.031; P=0.596) and percentage of anaerobic exercise (ICC(2,1), absolute agreement=−0.003; P=0.698) values during the game, respectively.

The average respiratory exchange ratio achieved by oarsmen were 0.96, an indication of anaerobic glycolysis at peak exercise. Oarswomen achieved a peak workload of 235 which is slightly more than oarsmen. This is an achievement of 81% of the predicted. The group average HR achieved by oarswomen was 95 BPM, which is an achievement of 95% of the predicted. The group average RER was 0.84 which indicates a mixture of aerobic and anaerobic glycolysis at peak exercise.\u0000The VO2 values obtained by Sri Lankan rowers are low compared to international standards. Despite the overall lower VO2 max obtained by male rowers, their VO2 at AT was at a higher percentage of their peak VO2, indicating better cardiovascular fitness.

However, some studies have also indicated that sports may lead to undesirable behavior when conducted under certain uncontrolled conditions. The purpose of this study was to assess the influence of selected contextual factors on character changes related to sports participation among secondary school students. The study focused on level of sports participation, gender, age, type of sport, school category, school status, school type, and class level of students as independent variables with potential to influence character changes related to sports participation. A Quasi-experimental research design was utilized, with the dependent variable of character traits assessed at the pre and post three months competitive games season. Purposive sampling was used to select 336 student-athletes from 24 (9.3%) of secondary schools in Nairobi city county. A close-ended questionnaire on character which was adapted from Individual and Team Character in Sport Questionnaire (ITCSQ) and Arizona Sport Summit Accord (ASSA) was utilized for data collection at the pre-and posttests. Matched Sample Wilcoxon Signed Rank test showed significant negative change in honest /integrity character component scores between pre-test and post-test (p=0.006). Multinomial Logistic Regression Analyses showed that boarding status, school category and type of sport can significantly (p<0.05) influence character changes among competitive student-athletes. Therefore it is concluded that boarding status, school category and type of sport can influence outcomes of sports experiences leading to positive or negative character change. It is therefore recommended that curriculum developers and implementers should consider contextual factors to optimize sports experiences and outcomes to promote desirable character changes and development.","PeriodicalId":36509,"journal":{"name":"Central European Journal of Sport Sciences and Medicine","volume":"27 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2023-02-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"83081871","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}

This study is a combined study of simultaneously embedded models, with quantitative methods as the primary method and qualitative methods as the secondary method. Fifty BAPOMI athletes from various sports statuses as students at DIY were recruited through purposive sampling with the consideration that they were implementing synchronous learning. This research also enrolled six coaches and trainers in BAPOMI DIY. Quantitative data was collected using a 1–5 scale questionnaire, and qualitative data using semi-structured interviews. Descriptive statistics analyze quantitative data, and qualitative data is analyzed by data reduction, data presentation, and conclusion. The results of the quantitative study show that the decrease in the mental strength of self-confidence of BAPOMI DIY athletes due to synchronous online learning is included in the high category. In the decline of mental toughness, fatigue is included in the moderate category. Decreased mental toughness is included in the high category. Decreased mental endurance motivation (training/competition) is included in the high category. Decreasing mental strength symptoms of depression are included in the high category. The results of this quantitative data are also in line with the statements of coaches and parents of students who stated that: during online learning, athletes are tired because there are more tasks, the interest in training is reduced compared to offline learning, less focus and less. from enthusiasm, tiredness from sitting in front of the laptop, and reduced concentration due to many lecture assignments. Athletes feel bored, are often late for practice, sometimes get permission to do college assignments, come, often ask for permission, decrease training motivation, decrease fitness, and don't look fit. It can be concluded that synchronous online learning takes too long and sits a lot that is not matched with regular physical activity among athletes, which can cause a decrease in mental toughness from various aspects at a high level. However, there is one aspect that is included in the level category low but still conditional. The role of the coach is becoming more and more critical because they can diligently control the physical and psychological development of the athlete.","PeriodicalId":36509,"journal":{"name":"Central European Journal of Sport Sciences and Medicine","volume":"14 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2023-02-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"81956284","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}

A. The shuttle run, pull-up, sit-up, and push-up portions of the Samapta B exam are all completed for a total of 60 seconds. Between each test item in the physical fitness B sequence is a five-minute rest break with a predefined time interval. The data were analyzed using bidirectional variance analysis (ANOVA), after which a Tukey test was run with a 0.05 significant level. For the entire data analysis procedure, SPSS software version 25 is employed.

The aim of our study was to identify and compare the bilateral differences in the internal and external rotation of the glenohumeral joint of crossminton players. The subject of our study were 13 crossminton players from Slovak Republic (25.1±9.3 years; 172.8±9.1 cm; 71.8±16.1 kg). The range of motion of internal (IR-ROM) and external rotation (ER-ROM) of the glenohumeral joint was measured bilaterally using a standard two-arm goniometer. Bilateral comparison, decimal and sport age pairwise comparisons were carried using the T-test for independent samples. Results point to the occurrence of glenohumeral joint adaptation. Given the bilateral differences, the dominant shoulder has lower IR-ROM (p < 0.05) and higher ER-ROM (p < 0.05) than the non-dominant shoulder. GIRD (IR difference > 13 °) was observed in 4 players. The decimal age of the players did not have a significant impact on the rotation values of the glenohumeral joint. Only IR-ROM of the dominant upper limb was lower with the growing sport age of the players (p < 0.05). Given the fact that adaptations in ROM of glenohumeral joint promote an increased injury risk, the present study reveals the relevance of monitoring and finding differences between upper limbs in crossminton players.","PeriodicalId":36509,"journal":{"name":"Central European Journal of Sport Sciences and Medicine","volume":"1 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2023-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"68049537","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}
