Bu çalışma, video tabanlı hareket analizlerinde kullanılmak üzere hareketli kamera aparatının yapımını açıklamakta ve serbest stil yüzmenin yatay hızı için sistemin geçerliğini rapor etmektedir. Çalışmaya dokuz erkek yüzücü (boy = 178.3 ± 6.3 cm, ağırlık = 82.6 ± 5.8 kg, yaş = 22.3 ± 3.86 yıl) katılmıştır. Yirmi metre serbest stil yüzme performansları hem hareketli kamera sistemi hem de sabit bir kamera kullanılarak kaydedilmiştir. Yüzücülerin bel bölgesine yerleştirilen bir işaretleyici yatay hızı hesaplamak amacıyla hareket analiz yazılımı kullanılarak takip edilmiştir. İki boyutlu hareket analizlerinin ardından iki sistemden elde edilen veriler incelenmiştir. Sabit kamera kayıtları kullanılarak hesaplanan yatay hızlar referans olarak kabul edilmiştir. Sonuçlar, hareketli kamera aparatı kullanılarak hesaplanan yatay hızların zaman serilerinin hiçbir noktasında referans değerlerden 0.05m/s’den fazla sapmadığını göstermiştir. Hoeffding’in D testi, 18 veri çiftinin anlamlı ölçüde birbirine bağımlı olduğunu (p<.05) ve veri serilerinin benzer eğriler çizdiğini ortaya koymuştur. Sonuç olarak geliştirilen aparatın hassasiyeti yüzmede kinematik analizlerin yapılmasına izin vermektedir ve sabit kamera sistemlerine alternatif olarak kullanılabilir.

This study describes the building of a moving camera apparatus for use in video-based motion analysis and reports its validity in the horizontal velocity of freestyle swimming. Nine male swimmers (height = 178.3 ± 6.3cm, weight = 82.6 ± 5.8 kg, age = 22.3 ± 3.86 years) participated to the study. Twenty meters freestyle swimming performances were recorded using both a moving camera apparatus and a stationary camera. A marker placed on the lumbar region of the swimmers was tracked to calculate horizontal velocity. After 2D motion analyses, the data obtained by two different methods were investigated. Horizontal velocities calculated using stationary camera recordings were taken as reference. Results showed that the horizontal velocities calculated using the moving camera apparatus’s recordings did not deviate from reference values more than 0.05 m/s at any point of the time series. Hoeffding’s D measure test revealed significant dependencies for 18 data couples (p<.05) indicating data series draw a similar trajectory. In conclusion, the accuracy of the apparatus allows for kinematic analyses in swimming and the can be used as an alternative to stationary cameras
