Ağırlıklı Squat Sıçrama Hareketi Esnasındaki Hız Değerlerinin Analizi: Anaerobik Güç ve Maksimal Kuvvet Önemli Bir Faktör Mü?

Bu çalışmanın amacı; ağırlıklı squat sıçrama hareketi esnasındaki hız değerleri için anaerobik güç ve maksimal kuvvetin önemli bir faktör olup olmadığının belirlenmesidir. Bu amaç doğrultusunda; Gümüşhane Üniversitesi Beden Eğitimi ve Spor Yüksekokulunda öğrenim gören ve farklı spor branşlarında aktif sporcu lisansına sahip olan 36 sporcu öğrenci (yaş: 21,4 ± 1,57 yıl; boy: 175,2 ± 5,91 cm; kilo: 68,7 ± 7,12 kg) çalışmaya gönüllü olarak katıldı. Çalışmada, katılımcıların hız parametrelerini belirlemek için kendi vücut ağırlıklarının % 40’ına karşılık gelen bir dış yük kullanılarak ağırlıklı squat sıçrama (SSYük) hareketi yaptırıldı. Ayrıca, katılımcıların maksimal dinamik kuvvet özelliğini belirlemek için tam squat (SQTam) hareketinde bir tekrarlı maksimal (1TM) kuvvet testi ve anaerobik güç testi yaptırıldı. Verilerin analizi için Shapiro-Wilk normallik testi, tanımlayıcı istatistik ve Pearson korelasyon analizleri kullanıldı. Analiz sonuçlarına göre; katılımcıların relatif ortalama anaerobik güç ve SQTam hareketindeki absolut ve relatif 1TM kuvvet değeri ile SSYük hareketinin konsantrik evresinde elde edilen zirve hız değerleri arasında pozitif yönde istatistiksel olarak anlamlı bir ilişki olduğu elde edildi. Ayrıca, absolut 1TM squat kuvveti ile hem absolut maksimal anaerobik güç hem de absolut ortalama anaerobik güç değerleri arasında pozitif yönde istatistiksel olarak anlamlı bir ilişki olduğu elde edildi. Bunun dışında, istatistiksel olarak herhangi bir anlamlı ilişki elde edilmedi. Sonuç olarak hem absolut hem de relatif bakımdan kuvvet ve zirve hız değerleri arasında anlamlı ilişki olmasından dolayı, kuvvet özelliği arttığında konsantrik evre esnasındaki zirve hız değerlerinde bir artış meydana geleceği ve hareket hızında bir gelişme sağlamak için maksimal kuvvet antrenmanlarının yapılması gerektiği ileri sürülebilir.

The Analysis of Velocity Values During Loaded-Squat Jump Movement: Are Anaerobic Power and Maximal Strength an Important Factor?

The aim of this study is to determine whether the anaerobic power and maximal strength are an important factor for velocity values during loaded-squat jump movement. For this purpose, 36 male students (age: 21,4 ± 1,57 years; height: 175,2 ± 5,91 cm; weight: 68,7 ± 7,12 kg) who are studying at school of physical education and sport at the Gumushane University and have active athlete license in different sport branches participated in the study voluntarily. In the study, loaded-squat jump (SJLoaded) movement was practiced by using an external load equaled to 40% of their body weights in order to determine velocity parameters of the participants. Also, in order to determine the maximal dynamic strength of the participants, one repetition maximal strength (1RM) in the full back squat (SQFull) movement and anaerobic power tests were done. For the analysis of data, Shapiro-Wilk normality test, descriptive statistics and Pearson Correlation analysis were used. According to the analysis results, there is a positive and statistically significant relationship between the absolute and relative 1RM strength values in the SQFull movement and mean relative anaerobic power values together with peak velocity values obtained in the concentric phase of SJLoaded movement of participants. Also, it was found that there is a positive and statistically significant relationship between 1RM squat strength and both absolute maximal anaerobic power and absolute mean anaerobic power values. There was no statistically significant relationship was found except for this. As a result, since there is a significant relationship between strength and velocity values in terms of absolute and relative, it can be asserted that as the strength increases, there will be an increase in peak velocity values during concentric phase and maximal strength training should be performed to provide an improvement in the movement velocity.
