Abstract

Yatay sıçrama, özellikle atletizm, basketbol ve futbol gibi sporlarda sporcuların patlayıcı gücünü ve performansını belirlemede kritik bir rol oynamaktadır. Bu çalışmanın amacı, MyJump 2 uygulamasının üniversite sporcularının yatay sıçrama performansını değerlendirmedeki geçerlilik ve güvenilirliğini incelemektir. Çalışma, nicel araştırma yöntemlerinden korelasyonel araştırma deseni kullanılarak tasarlanmıştır. Araştırmaya Burdur Mehmet Akif Ersoy Üniversitesi Spor Bilimleri Fakültesi’nde en az bir yıl lisanslı spor yapmış 40 öğrenci katılmıştır. Yatay sıçramalar, MyJump 2 uygulaması ile geleneksel şerit metre kullanılarak eş zamanlı olarak ölçülmüştür. Veriler, Jamovi paket programı ile analiz edilmiştir. Normallik versayımı Shapiro Wilk testi ile control edilmiştir. Pearson korelasyon katsayısı analizi ile geçerlik değerlendirilirken, sınıf içi korelasyon katsayııs analizi (ICC) ile güvenirlik değerlendirilmiştir. Pearson korelasyon analizi sonuçlarına göre, MyJump 2 ile şerit metre arasında mükemmel bir geçerlik bulunmuştur (r = 0.99). Bland Altman analizi sonuçları ise MyJump 2’nin sadece 0.42 cm'lik bir ortalama yanlılık gösterdiğini ortaya koymuştur. Test-tekrar test güvenilirliği ise sınıf içi korelasyon katsayısı (ICC) ile değerlendirilmiş ve oldukça yüksek bir güvenilirlik tespit edilmiştir (ICC = 0.99). Bu bulgular, MyJump 2 uygulamasının, spor bilimlerinde ve antrenman programlarında kullanılabilecek güvenilir ve geçerli bir araç olduğunu göstermektedir. Ayrıca, MyJump 2’nin taşınabilir ve düşük maliyetli olması, pahalı laboratuvar ekipmanlarına erişimi olmayan antrenörler ve sporcular için pratik bir alternatif sunmaktadır. Bu sayede alan uzmanları, MyJump 2'yi saha koşullarında yatay sıçrama performansını değerlendirmek için etkili bir ölçüm aracı olarak kullanabilirler.

Validity and Reliability of Myjump 2 Application in Assessing Horizontal Jump: A Test-Retest Study

Abstract

Horizontal jumps are critical in determining athletes' explosive power and performance, especially in track and field, basketball, and football. This study examines the validity and reliability of the MyJump 2 application in evaluating the horizontal jump performance of university athletes. The study was designed using correlational research, one of the quantitative research methods. Forty students who have done licensed sports for at least one year at Burdur Mehmet Akif Ersoy University Faculty of Sports Sciences participated in the study. Horizontal jumps were measured simultaneously using the MyJump 2 application and traditional tape measure. The data were analyzed using the Jamovi package program. Normality data were checked with the Shapiro-Wilk test. Validity was evaluated with the Pearson correlation coefficient analysis, while reliability was assessed with the intraclass correlation coefficient analysis (ICC). According to the Pearson correlation analysis results, perfect validity was found between MyJump 2 and the tape measure (r = 0.99). The Bland Altman analysis showed that MyJump 2 had an average bias of only 0.42 cm. Test-retest reliability was assessed using the intraclass correlation coefficient (ICC), and very high reliability was found (ICC = 0.99). These findings show that MyJump 2 is a reliable and valid tool that can be used in sports sciences and training programs. In addition, MyJump 2 is portable and low-cost, providing a practical alternative for coaches and athletes who do not have access to expensive laboratory equipment. In this way, field experts can use MyJump 2 as an effective measurement tool to evaluate horizontal jump performance in field conditions.
