Özet
Bu araştırmada kadın voleybol oyuncularının algıladıkları ve gerçekleştirdikleri
performanslarının dikey ve yatay sıçrama açısından karşılaştırılması amaçlanmıştır.
Araştırmaya Türkiye Kadınlar Voleybol 2. Ligi’nden 14 kadın voleybol oyuncusu gönüllü
olarak dahil edilmiştir. Katılımcıların yaş ortalaması 18,71 ± 5,97 yıl, boy uzunluğu ortalaması 172,57
± 6,02 cm, vücut ağırlığı ortalamaları 64,57 ± 7,22 kg ve spor deneyimi ortalamaları 7,07 ± 5,86
yıldır.
Kadın voleybol oyuncularının dikey olarak sıçrama mesafeleri ve bu mesafeye ilişkin olarak
yargıda bulunmaları yukarıdan sarkaç gibi sartılan bir top kullanılarak gerçekleştirilmiştir. Katılıcılar
sabit olarak duran topun yüksekliğine göre dikey olarak sıçrayabilecekleri mesafe hakkında
değerlendirmeleri alınmış ve sonrasında ise maksimal sıçrama ile topa temas ettikleri mesafe
kaydedilmiştir. Durarak uzun atlamada ise katılımcıların çift ayak öne doğru sıçrayabilecekleri
mesafeyi tahmin etmeleri istenmiş ve ardından öne doğru maksimal sıçrama yaptırılarak ulaştıkları
mesafe kaydedilmiştir.
Tahmini ve gerçek değerlerin karşılaştırılmasında bağımlı örneklemler için t-testi
kullanılmıştır. Dikey sıçrama ve durarak uzun testlerinin tahmini ve gerçek değerler arasındaki
farkların karşılaştırılmasında Mann Whitney U testi uygulanmıştır. Değişkenler arasındaki ilişkinin
incelenmesinde Pearson Korelasyon Analizi kullanılmıştır.
Kadın voleybol oyuncularının dikey olarak sıçradıkları ve sıçrayabileceklerini tahmin
ettikleri mesafeler karşılaştırıldığında gerçek sıçrama mesafelerinin tahmin ettikleri değerlerden
anlamlı düzeyde daha yüksek olduğu tespit edilmiştir (t = 4,836; p < 0,05). Durarak uzun atlama
mesafesinde ise tahmini değerin gerçek değerden istatistiksel olarak anlamlı düzeyde daha yüksek
olduğu belirlenmiştir (t = -2,337; p < 0,05).
Her iki parametreye ait gerçek ve tahmini değerlerin farklar karşılaştırıldığında istatistiksel
olarak farklılık olduğu, durarak uzun atlamadaki farkın anlamlı düzeyde daha büyük olduğu
belirlenmiştir (U = 28,000; p < 0,05).
Dikey sıçramaya ait tahmin edilen ve gerçekleştiren değerler arasında yüksek düzeyde pozitif
ilişki olduğu belirlenmiştir (r= 0,886; p < 0,05). Durarak uzun atlamaya ait tahmin edilen ve
gerçekleştiren değerler arasında ise anlamlı bir ilişki tespit edilmemiştir (r= 0,427; p > 0,05).
Kadın voleybol oyuncularının dikey sıçrama için kendi performansları hakkında bulundukları
yargının gerçek dikey sıçrama mesafesinden daha düşük olduğu, durarak uzun atlamada ise voleybol
oyuncularının kendi performansları hakkında verdikleri yargının gerçek atlama mesafesinden yüksek
olduğu tespit edilmiştir.
This study aimed to compare the perceived performance and actual performance related to vertical jump and standing broad jump in female volleyball players. Fourteen female volleyball players who were from Turkish Women Volleybal 2nd league volunteered to participate for the study (Age 18.71 ± 5.97 years, height 172.57 ± 6.02 cm, weight 64.57 ± 7.22 kg, and sport experience 7.07 ± 5.86 years). Actual and perceived performance of vertical jump in female volleyball players were measured by using a ball that could be suspended from above and could be moved up and down. Participants judged about their vertically jumping distances while the suspended ball was stable. Then, their actual vertical jumping distance were measured by touching the suspended ball. To the perceived standing broad jump, participants stood behind of a start line and evaluated their own how distance they could jump using their feet together and swaying their arms. After that, their actual standing broad jump performances were measured. Actual and perceived performances were compared by using the paired t-test. Mann Whitney U test was conducted to compare differences between actual and perceived performances. A Pearson correlation analyses was used to determine correlations between variables. When compared the actual and the perceived performances for vertical jump in female volleyball players, actual jumping distance was higher than the perceived jumping distance (t=4.836; p<.05). On the other hand, the perceived performance was significantly higher than actual performance in standing broad jump (t=-2.337; p<.05). When compared differences between actual and perceived performances, the difference in standing broad jump was higher than difference in vertical jump (U=28.000; p<.05). A statistically significant high level of positive correlation was found between the actual and the perceived vertical jumping distances (r=0.886; p<.05). There was no significant correlation in standing broad jumping between the actual and the received performances (r=0.427; p>.05). In conclusion, these results showed that the judgment of female volleyball players about their performance for vertical jumping was lower than their actual vertical jumping distance. On contrary, the resent results revealed that female volleyball players judged higher performance than their actual performance for standing broad jumping.
