Dikey sıçrama performansının belirlenmesinde akıllı telefon uygulaması kullanılabilir mi?

Öz

Amaç:Bu araştırma, dikey sıçrama yüksekliğini ölçmek için özel olarak tasarlanmış olan MyJumpakıllı telefon uygulamasının dikey sıçrama için kullanılabilirliğini incelemek amacıyla yapılmıştır.

Materyal ve Yöntem: Bu araştırmanın katılımcılarını, çalışmalara gönüllü olarak katılan Spor Bilimleri Fakültesinde öğrenim gören ve dikey sıçrama tecrübesine sahip 86 sağlıklı erkek öğrenci (yaş 22,3±1,7yıl, boy 173,3±13,8cm ve beden ağırlığı 71,7±13,8 kg) oluşturmuştur. Katılımcılar ısınmanın ardından 500 Hz örnekleme hızında kuvvet platformu üzerinde beş aktif dikey sıçrama testini gerçekleştirdi. Katılımcılar her bir sıçramadan sonra 2 dakika pasif olarak dinlendi. Tüm sıçramalar eşzamanlı olarak iPhone 6S akıllı telefonunun 240 Hz yüksek hızlı video çekim özelliği ile kaydedildi ve MyJump akıllı telefon uygulamasıyla analiz edildi. Dikey sıçrama esnasında kuvvet platformu yöntemi ile MyJump akıllı telefon uygulaması yöntemlerinden elde edilen verilerin analizinde Pearson korelasyon analizi ve Bland- Altman grafik yöntemleri kullanıldı. 

Bulgular:Dikey sıçrama için kullanılan kuvvet platformu yöntemi ile MyJump akıllı telefon uygulaması yöntemleri arasında pozitif yönde oldukça yüksek ilişki bulunmuştur (r=0,993, p<0,01). Ayrıca Bland - Altman grafiği incelendiğinde iki yöntem verilerinin çok büyük oranda hesaplanan sınırlı alan içinde olduğu gözlenmiştir. 

Sonuçlar: Bu sonuçlara göre, dikey sıçrama esnasında havada kalınan süreyi ve hesaplanan dikey sıçrama yüksekliğinin belirlemesinde kullanılan MyJump telefon uygulaması yönteminin, altın standart olarak kabul edilen kuvvet platformu yöntemi ile %99,3 oranında benzer olduğu belirlenmiştir.

Can IPhone application be used to determine vertical jump performance?

Öz

Aim: This research was conducted to examine the availability of My Jumpapp which was specially designed to measure vertical jumping height.

Methods: The participants of this study consisted of 86 healthy male (age 22.3 ±1.7-year, height 173.3 ± 13.8 cm and weight 71.7 ± 13.8 kg) students studying at the Faculty of Sports Sciences voluntarily participating in the work and with a vertical jump experience. The participants performed five active vertical jump tests on the force platform at a sampling rate of 500 Hz after warming up. Participants rested passively for 2 minutes after each jump. All jumps were simultaneously recorded with the 240 Hz high-speed video capture of the iPhone 6S smartphone and analyzed with the MyJump smartphone application. Pearson correlation analysis and Bland-Altman graphical methods were used in the analysis of data obtained from force platform and MyJump smartphone application methods during the vertical jump.  

Results: There was a high positive correlation between the force platform method used for vertical jump and the method of MyJump smartphone application (r=0.993, p<0.01). Furthermore, when the Bland - Altman graph was examined, it was observed that the data of the two methods were in the calculated limited area.

Conclusion: According to these results, it was determined that the method of MyJump telephone application, used to determine the height of the airborne staff and the calculated vertical jumping height during the vertical jump, was 99.3% similar to the force platform method accepted as the gold standard.
