Data were collected through the personal information form, the International Physical Activity Questionnaire-Short Form, the COV19-Impact on Quality of Life scale, and Positive-Negative Affect Schedule (PANAS). Data were collected through stratified sampling from Recep Tayyip Erdogan University and Kırşehir Ahi Evran University. The sample of the study consisted of 888 students. The obtained data were analyzed using SPSS 26.0. Necessary assumptions were ensured before the analysis. Afterwards, descriptive statistics and MANOVA were used in the research. It has seen that the number of students who do not do sports under license, who passively participate in sports 2-3 times a week, and whose physical activity level is moderate are more in number. The findings show that students who do sports under license, passively participate ...

In addition, another aim of the study is to examine the effects of mindfulness levels of athletes on competitive state anxiety and track performance. The study group was determined according to the convenience sampling method in the study, in which the survey model, one of the quantitative research methods, was used. The sample of the research consisted of 292 athletes. The data were collected with the Mindfulness Inventory For Sport, Competition State Anxiety Inventory-2 and track performance information. Before the analysis, the assumption of normality was checked and descriptive statistics were determined. Then, relational (Pearson) and comparative (MANOVA and ANOVA) inferential statistical tests were performed. In athletes, there is a negative aspect weak level between mindfulness with cognitive anxiety and physical anxiety. In addition, positive aspect weak level between mindfulness; track performance and a positive moderate significant relationship was found between mindfulness and self-confidence. Athletes with high levels of mindfulness experienced significantly lower levels of physical anxiety and felt higher levels of selfconfidence. Again, it was found that athletes with a high level of conscious awareness had a significantly higher level of track performance. With the high level of mindfulness of the athletes, their self-confidence can increase and their physical anxiety can decrease. Similarly, high mindfulness can increase the performance of athletes.

The sample comprised 549 students who were enrolled in a provincial state university in Turkey, and who volunteered to take part in the study. The survey was comprised of two parts. The first part contained questions to identify gender and the extent of the student’s active and passive participation in sport. Active participation was defined by the status of licensed athlete. The second part comprised the Oxford Happiness questionnaire compact version and the UCLA Loneliness Scale-III. Before the analysis, the Levene test was conducted to confirm the homogeneity of the variances. After determining that the variances were homogeneous, four two-way ANOVAs were carried out to test the hypotheses that students’ active and passive involvement in sport was associated with lower levels of loneliness and higher levels of happiness and that this effect ...

The athletes’ ages are between 15 and 55 (19.41±5.57). As part of the convenience sampling approach, data were collected from 40 of Turkey’s 81 provinces online (using a web-based Google form). The questionnaire consists of two parts. In the first part, there are questions about the demographic characteristics of the athletes. In the second part, some questions measure perceived stress, positive/ negative emotions, and mental toughness information in sports. Confirmatory factor analysis was used to understand whether the scales were suitable for the sample group and to increase the reliability of the mediator model. In the study, the effect of negative and positive emotions on mental toughness was tested...

The data of the study were collected through the Personal Information Form, International Physical Activity Questionnaire-Short Form (IPAQ-SF) and Depression, Anxiety, Stress Scale (DASS-21). After obtaining the necessary ethics committee approval for the study, data were collected from 55 of 81 provinces in Turkey by online method and convenient sampling. The sample of the study consisted of 488 adult individuals who filled the scales completely. Data obtained from adult individuals were analysed by using the SPSS (Statistical Package for Social Sciences) 26.0 program. Before the analyses, the assumptions required for the MANOVA test were discussed. After the necessary examinations were performed, descriptive statistics and the MANOVA test were used in the analysis of the data regarding the mean scores of the answers given by 488 adult individuals to the scales. Most of the individuals participating in the study had normal scores for anxiety (70.7%), depression (64.3%) and stress (77.5%). Despite this situation, it was observed that there were individuals with severe and very advanced anxiety (11.5%), depression (12.3%) and stress (9.4%) score ranges. In terms of physical activity levels, 56.9% (n=278) of the participants were found to be inactive and minimally active. The hypothesis test results showed that the anxiety, depression and stress levels of inactive individuals were significantly higher than those in the minimally active and very active groups. As a result, it can be said that there was a strong link between physical activity and negative emotions for adults.

Araştırmaya 2021-2022 eğitim öğretim döneminde Rize'de öğrenim gören 381 ortaokul öğrencisi ile 667 ebeveyn katıldı. Veri toplama aracı olarak kişisel bilgi formu ile Uluslararası Fiziksel Aktivite Anketi Kısa Formu ve Çocuklar İçin Fiziksel Aktivite Anketi kullanıldı. İstatistik yöntemde verilerin yüzde dağılım ve frekans değerleri tanımlayıcı istatistikle belirlendi. Normallik testi olarak Shapiro Wilk Test ve Basıklık Çarpıklık değerleri kullanıldı. İkili karşılaştırmalarda parametrik veriller için Bağımsız Örneklem T Testi, parametrik olmayan veriler için ise Mann Whitney U Testi kullanıldı. Üç ve üzeri grupların karşılaştırılmasında parametrik veriler için Tek Yönlü Varyans Analizi, parametrik olmayan veriler için ise Kruskal Wallis testi kullanıldı. İlişki analizinde ise Spearman Korelasyon testinden yararlanıldı. Ebeveynlerin anne baba durumlarına göre, çocukların yaş ve cinsiyetlerine göre fiziksel aktivite düzeyleri arasında anlamlı farklılıklar olduğu görüldü. Annelerle babaların fiziksek aktivite puanları arasında ise orta düzeyde bir ilişki olduğu tespit edildi. Sonuç olarak COVID 19'a yakalanmanın ebeveyn ve çocuklarda fiziksel aktivite düzeyleri açısından farklılığa sebep olmadığı, erkek ebeveynlerin ve erkek çocukların kadın ebeveyn ve kız çocuklara göre daha fazla fiziksel aktivite düzeyine sahip olduğu, ebeveynlerle çocukları arasında fiziksel aktivite düzeyi açısından bir ilişki olmadığı tespit edildi.

The Golden apple snails is widely regarded as worst invasive pest species in the rice growing area. It normally destroys the young stems and leaves paddy and could consume 7-24 rice seedlings per day. The experiment research started with the mortality test of the golden apple snail, meanwhile hexane extract fraction and etanol extract fraction have completely jumble mode; using the lethal concentration (LC) have mean to describe short term potency of poisonous (toxicity) from materials and can gave little effect or impact for environment; processing phytochemical test from n-hexane extract and etanol extract of root D.elliptica and P.edule showed positive to contain tanin, saponin and fenol. The data of LC 50 from nhexane fraction measure with probit analyze (9,905 mg L-1) by D.elliptica L. with high toxic category, and n-hexane fraction (11,574 mg L-1) by P.edule Reinw. with toxic category are more effective for golden apple snail control. The golden apple snail mortality was highest using 5000 ppm n-hexane fraction showed 93,3% from D.elliptica and using 5000 ppm n-hexane fraction from P.edule showed 63,3%. In conclusion, both of extracts from D.elliptica roots and P.edule seeds was showed potency as botanical mollusicicides and it can be apply in the field.

national sport federations (NSFs) need to undertake performance measurement models. In this study, using inverse
Data Envelopment Analysis (InDEA) models, an efficiency analysis of 15 sports federations of Turkey which
participated in the 18th Mediterranean Games was performed. The results revealed that the average efficiency of the
sports federations was considerably low. The suggested InDEA model can help managers of NSFs and different
organizations with production analysis, performance measurement, resource planning and strategic management.
