ÖZET
Amaç: 10-12 Yaş erkek yüzücülerde 50m kelebek maksimum performans yüzüşünde çıkış ve dönüş
evrelerinin toplam zamana etkisinin belirlenmesidir.
Materyal ve Metod: Çalışma grubunu ENKA Spor Kulübü altyapı takımında lisanslı 10-12 yaş aralığında 23
erkek yüzücü (yaş: 11,13±0,81 yıl, boy: 160,89±10,01 cm, vücut ağırlığı: 48,17±8,87 kg, VKİ: 18,49±1,97
kg/m2) oluşturmuştur. Yüzücülerin boy, vücut ağırlığı ve kulaç uzunluğu ölçümlerinden sonra, aynı gün 50m
kelebek yüzme tekniğindeki sprint çıkış-dönüş performans ölçümleri için kinematik analiz yapılmıştır
(Dartfish 9 Team pro). Analizler sırasında video kayıtları GoPro HERO7-Black ile alınmıştır. Analizler
sırasında yüzülen toplam süre, mesafenin birinci ve ikinci yarısının süreleri ölçülmüştür. Veriler
değerlendirilirken tanımlayıcı istatistiksel metotlar (minimum, maksimum, ortalama, standart sapma)
kullanılmıştır. Çıkış ve dönüş evrelerinin toplam zamana etkisinin belirlenmesinde Pearson kolerasyon testi ve
lineer regresyon analizi uygulanmıştır.
Bulgular: İlk 25m ve son 25m ile yüzme zamanı 50m toplam yüzme zamanı için hesaplanan regresyon modeli
(F(1,22)= 329,560, p=0,000**), (F(1,22)=519,754, p=0,000**) istatistiksel olarak anlamlı bulunmuştur. İlk 25m
yüzme zamanı, 50m toplam yüzme zamanın %94’ünü, son 25m yüzme zamanı, 50m toplam yüzme zamanın
%96’sını (R=0,980; R2=0,961) açıklamaktadır.
Sonuç: İlk ve son 25m yüzme zamanı 50m toplam yüzme zamanını etkilemektedir.

ABSTRACT
Aim: The aim of this study is to investigate the associations between the individual performance of physical
education and sports teachers and their perception of digital transformation. The aim of this study is to
investigate the effect of the start and turn on the total time in the 50m butterfly sprint swim in 10-12 year old
male swimmers.
Material and Method: The study group consisted of 23 male swimmers (age:11.13±0.81 years,
height:160.89±10.01 cm, body weight:48.17±8.87 kg, BMI:18.49±1.97 kg/m2) licensed in the ENKA Sports
Club youth team, aged 10-12. After the swimmers' height, body weight and stroke length measurements,
kinematic analysis was performed for the start-turn performance measurements in the 50m butterfly swimming
technique on the same day (Dartfish 9 Team pro, USA). During the analyses, video recordings were made with
GoPro HERO7-Black. During the analyses, the total time swim, the times of the first 25m and second 25m of
the distance were measured. Descriptive statistical methods (minimum, maximum, mean, standard deviation)
were used to evaluate the data. Linear regression analysis and Pearson correlation test were used to determine
the effect of the start and turn phases on the total time.
Results: The regression model calculated for the first 25m and last 25m swimming time and the total
swimming time of 50m (F(1,22)= 329.560, p=0.000**), (F(1,22)=519.754, p=0.000**) was found to be
statistically significant. The first 25m swimming time explains 94% of the total 50m swimming time, the last
25m swimming time explains 96% of the total 50m swimming time (R=0.980; R2=0.961).
Conclusions: The first and last 25m swimming time affects the total 50m swimming time.
