However, more attention should be paid to the proprioception that controls the force and joint position in gymnastics. The contribution of its training to proprioceptive progression has yet to be adequately explored. The aim of the study was to (1) evaluate the joint position sense development in young aerobic gymnasts of different age groups and (2) investigate the relationship of position sense with execution success in competition. 112 competition athletes from four different age groups participated in the study. joint position sense tests were performed during the Aerobic Gymnastics Turkey Championship competitions. There were negative and significant correlations between 45o knee extension absolute errors and competition execution points. The 45o knee flexion absolute score correlated to competition execution points. 90o hip flexion absolute error scores were significantly associated with competition execution points. A positive correlation was found between the age of the gymnasts and the competition execution points. Considering the entire sample, results demonstrated that a final model consisting solely of hip extension absolute scores was able to explain a significant amount of variance in competition execution points. When the data is partitioned according to gender, the model fails to explain variation in competition execution scores in the male sample. However, a final model consisting of joint position sense error scores of hip flexion and knee extension could explain a significant proportion of variance in competition execution points of the female sample. Gymnasts who made more positional errors had lower execution scores. Target position replication accuracy in gymnasts improved with age. The effect of joint position sense accuracy in predicting the outcome of the competition was significant. Training that develops joint position sense can improve gymnasts' competitive results.","PeriodicalId":126066,"journal":{"name":"Spor Bilimleri Araştırmaları Dergisi","volume":"22 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-03-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123878748","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}

Ancak nicel yöntemlerle, psikolojik açıdan bir konunun derinlemesine incelemesi pek mümkün olmamaktadır. Dolayısıyla KS’nin nitel araştırma yöntemlerinden faydalanılarak etkilerinin incelenmesi, uygulama sonrası bireylerde oluşturduğu duygu durumu ve hissin derinlemesine araştırılmasını mümkün kılacaktır. Bu bağlamda bu araştırmanın amacı düzenli antrenman yapan ve sürekli gecikmiş kas ağrılarına maruz kalan fitness sporcularının toparlanmasında KS’nin etkilerini nitel bir yöntemle incelemektir. Nitel veri toplama teknikleri ile ele alınan bu araştırmada, yarı yapılandırılmış görüşme tekniği kullanılmıştır.

Katılımcılar antrenmandan hemen sonra köpük silindir ile kendi kendine miyofasyal gevşeme (KSMG) tekniğini uygulamışlardır ve 72 saat sonra katılımcılar ile görüşme yapılarak veriler toplanmıştır. Bu araştırmada altı adımlı tematik analiz tekniği kullanılarak ses kayıt dökümleri üzerinden analiz yapılmıştır. Araştırmanın sonucunda KSMG uygulamalarının sporcuların gecikmiş kas ağrılarının zirve noktasında ağrı şiddetini ciddi derecede azalttığı belirlenmiştir.

Referees not only manage the football match, but they are also the people who are psychologically affected by the atmosphere of the match and are held responsible for any mistake. This responsibility for the referees seems to have eased somewhat with the development of technology.Yet, unless an evaluation is made from the point of the referees, this situation will remain a mystery. This study aims to evaluate the attitudes of football referees towards the VAR system with the Q method. The methodological model of the study was the Q method, which includes qualitative and quantitative research methods. 25 referees included in the study with the snowball sampling method constitute the study group. The study data were analyzed using the PQMethod 2.35 program, which was developed for Q method studies. The principal component analysis method was used in the analysis of the data. After the analyzes made in the Q method, the data were divided into factors. As a result of principal component analysis and hand rotation afterward, it was seen that the opinions of the participants were gathered under two factors. The questions that the participants gathered under two different factors got higher scores were indicated by their Z scores. The reasons behind it were examined by interviewing the scores obtained from the quantitative data regarding the statements that the participants agreed and did not agree with. As a result, while there is a decrease in the sense of confidence in the referees' VAR system, in themselves and the profession, it is among the results obtained from the opinions that the elimination of injustice is a practice that allows the deserving to win.","PeriodicalId":126066,"journal":{"name":"Spor Bilimleri Araştırmaları Dergisi","volume":"15 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-02-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"134224891","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 study consisted of 22 (20.64 ± 1.91 years) healthy young women. The participants were divided into two groups according to their verbal expressions as menstruating with pain (n=11) and menstruating without pain (n=11). The study used a calendar-based counting method reported by women and an ovulation prediction kit to determine urinary LH surge. After the menstrual cycle phases were determined, Wingate anaerobic performance test measurements were applied to the participants in three phases (late follicle, ovulation and mid-luteal phase). Besides, the Pittsburgh sleep quality index was used to determine women’s sleep quality, and the menstrual symptom scale was used to measure menstrual symptoms. Mann-Whitney U test, one of the non-parametric tests, was used in the data analysis. In statistical analysis, the level of significance was accepted as p < 0.05. Spearman correlation analysis was used to determine the relationship between menstrual pain, sleep quality and anaerobic performance. As a result, the average sleep quality of the participants was higher than the painless group. Menstrual symptom scale \"pain symptoms\", and \"coping methods\" scores and menstrual symptom scale total scores differed between the groups. The study found that the power drop score, one of the anaerobic performance scores, differed between the groups in the mid-luteal phase.

The population of the study comprises students of Necmettin Erbakan University and Karamanoğlu Mehmetbey University, while the sample group consists of 263 participants. T-test and ANOVA were conducted in data analysis. According to the results of the research, while there was a significant relationship between social addiction and leisure involvement in perceived social welfare and weekly leisure time variables, no significant relationship was found between gender variable and social addiction and leisure involvement. It was concluded that leisure involvement has an effective role on social commitment and evaluating leisure activities with typical leisure activities can positively affect social connectedness.","PeriodicalId":126066,"journal":{"name":"Spor Bilimleri Araştırmaları Dergisi","volume":"82 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-02-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114733109","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}
