This study aims to determine the validity and reliability of the My Jump Lab (MJL) application in measuring vertical jump performance. A total of 40 volunteer athletes (age: 21.95±2.23 years; height: 170.74±10.28 cm; body weight: 66.50±12.35 kg), 21 males and 19 females, who regularly train in two different branches (football: 28; tennis: 12) at the amateur level, participated in the study. A countermovement jump (CMJ) test was utilized to evaluate jumping performance. Before each test, a standardized 5-minute warm-up protocol was applied. Two CMJ trials were conducted for each measurement, with a two-minute rest interval between trials. The best performance of the athletes was recorded. To analyze the validity and reliability of the MJL application, measurements were simultaneously recorded using the MJL app installed on a smartphone (iPhone 14 Pro Max, Apple, USA) and the Opto Jump photoelectric cell system (Opto Jump Next, Microgate, Italy), a validated tool. In a randomized order, measurements were carried out on three separate days at 24-hour intervals. Criterion validity was tested using Pearson’s correlation coefficient, while reliability was evaluated through the test-retest method with the Intraclass Correlation Coefficient (ICC). The paired samples t-test was used to examine the differences between the test scores obtained from the two systems. Additionally, Bland-Altman analysis was conducted to visually evaluate the agreement between the CMJ height values obtained from the two methods. The findings revealed high-reliability coefficients for CMJ height values in both methods. The paired samples t-test results (p > 0.05) showed no significant differences between the two systems. Furthermore, the Bland-Altman analysis indicated no systematic bias between the two measurement methods. In conclusion, the validity analyses performed on the MJL application demonstrated that it provides reliable and acceptable results. Its low cost and ease of use make it a practical tool for coaches and sports scientists in assessing CMJ performance.

Bu araştırmanın amacı sporcuların dikey sıçrama performansını ölçmek amacıyla kullanılan My Jump Lab (MJL) uygulamasının geçerlilik ve güvenirliğinin belirlenmesidir. Araştırmaya, amatör seviyede iki farklı branşta (futbol: 28; tenis: 12) düzenli olarak antrenman yapan 21 erkek ve 19 kadın olmak üzere toplam 40 gönüllü sporcu katılmıştır (yaş: 21,95±2,23 yıl; boy: 170,74±10,28 cm; vücut ağırlığı: 66,50±12,35 kg). Araştırma kapsamında sıçrama performansını değerlendirmek için dikey sıçrama (DS) testi kullanılmıştır. Her ölçüm öncesinde beş dakikalık standart bir ısınma protokolü uygulanmıştır. Her ölçüm için iki kez DS testi yaptırılmıştır. Ölçümler arasında iki dakikalık dinleme süresi verilmiş olup sporcuların en iyi performansı kaydedilmiştir. Bu esnada MJL uygulamasının geçerlik ve güvenirlik analizleri için akıllı bir cep telefonuna (14 Promax, Apple, ABD) kayıtlı MJL uygulaması ve Opto Jump fotoelektrik hücre sistemi (Opto Jump Next, Microgate, İtalya) kullanılmıştır. Bu iki sistemde eş zamanlı olarak çalıştırılmış ve kullanılmıştır. Ölçümler 3 farklı ölçüm gününde randomize bir şekilde 24 saat arayla gerçekleştirilmiştir. İstatistiki analiz yöntemlerinden, geçerliliği test etmek için ölçüt geçerliği tekniği esas alınırken, güvenirliği test etmek için test-tekrar test yöntemi kullanılmıştır. MJL uygulamasının güvenirlik testi için sınıf içi korelasyon katsayısı (ICC) kullanılırken ölçüt geçerliğini sınamak için Pearson korelasyon katsayısı incelenmiştir. Her iki ölçme aracı arasındaki test puanlarının farklılığı tespit etmek için ilişkili örneklemlerde t-testi kullanılmıştır. Son olarak, MJL uygulaması için iki ölçüm yöntemi arasındaki uyumu görsel olarak değerlendirmek amacıyla DS sıçrama yüksekliği değerleri Bland-Altman tekniği ile incelenmiştir. Araştırma bulgularına göre her iki uygulama için DS yüksekliği değerlerinin güvenirlik katsayısının yüksek düzeyde olduğu tespit edilmiştir. Her iki ölçüm yöntemi arasındaki farkın t-testi sonuçlarına göre anlamlı düzeyde olmadığı belirlenmiştir (p>0.05). Son olarak Bland-Altman analizi sonuçları da her iki ölçme yöntemi arasında sistematik bir hata olmadığını göstermiştir. Sonuç olarak MJL uygulaması üzerinde yapılan geçerlik analizleri, güvenilir ve kabul edilebilir nitelikte sonuçlar ortaya koyduğu tespit edilmiştir.
