This systematic review and meta-analysis aims to investigate whether the My Jump app produces valid and reliable results when measuring vertical jump height. To identify potential studies for inclusion in this systematic review and meta-analysis, a search strategy was implemented in the MEDLINE (via PubMed) and Web of Science databases. Meta-analyses of validity were performed in two ways: (1) mean and standard deviations were compared between the My Jump and criterion measurements to assess the agreement of raw scores; (2) correlation coefficients were used to determine the consistency of the rankings within-group in the My Jump and criterion measurements. The meta-analysis of reliability was conducted using intraclass correlation coefficients (ICC). Heterogeneity was determined by Cochrane’s Q statistic and its p-value, I-squared value, and tau-squared value. The risk of publication bias was explored using funnel plot symmetry, and asymmetries were confirmed using the extended Egger’s test. Following the identification of studies providing inclusion criteria, 12 studies were included in the present meta-analysis. The meta-analysis conducted for identifying the agreement between raw scores showed that there was no significant difference between My Jump and the criterion measurements. The meta-analysis for identifying the consistency of the rankings within-group indicated that there was a high correlation between My Jump and criterion devices. Additionally, it is found that the My Jump app had nearly perfect reliability scores. Consequently, this study showed that the My Jump app presented high agreement and consistency scores with reference methods.
Current study aimed to examine Erzurum Technical University Faculty of Sport Sciences students’ sports competence levels and self-efficacy levels according to various variables. A total of 116 students, fifty four female, and sixty two male, participated in the study, in which the quantitative research model was used. In the first part, the Personal Information Form was used to determine the demographic characteristics of the participants, the second part used the Self-Efficacy Attitude Scale, and the third part used the Competence in Sports Scale. Frequency analysis, kurtosis, skewness test, One-Way ANOVA analysis, t-test, and correlation analysis were used in the research. A positive and moderately significant relationship was found between the Self-Efficacy Attitude Scale and the Competence in Sports Scale. According to gender, it was determined that male students’ competence in sports was significantly higher than female students’ sports competence. According to the branch variable, it was determined that the self-efficacy status of the students who do individual sports is significantly higher than the self-efficacy status of the students who do team sports and who do not have a branch. In addition, according to the age variable, no significant relationship was found between the competence status of the students in sports and their self-efficacy attitudes. As a result, it can be said that male students have higher proficiency in sports than female students, and they feel more competent. It has been determined that the self-efficacy attitudes of the students who do individual sports are higher than those who do team sports.
The present study aimed to determine the current state of water buffalo breeders in Silvan, Bağlar, Yenişehir, and Sur counties of Diyarbakır province in Turkey, and to reveal the aspects of shelter, grazing, calf breeding, brood use, meat and milk production practices, care and health protection, expectations from breeding practices and current problems. The results of the face-to-face surveys were used carried out with a total of 147 business owners engaged in water buffalo breeding in four counties. In the research, the average number of water buffaloes per farm was determined to be 11.03. The breeders have reported that they continue to raise water buffaloes for reasons such as making a living, high quality of water buffalo milk, and benefiting from the available subsidies. The average lactation period of water buffaloes was 7.1 months, the average daily milk obtained per animal was determined to be 3.63 liters. The milk obtained is mostly evaluated as yogurt, cheese, and butter. As a result, it was determined that almost all of the breeders are satisfied with water buffalo breeding, they see breeding as a family profession, and they are aware of the quality and importance of water buffalo products.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
