Abstract

The purpose of this study
was to investigate the relationship between velocity and power values during loaded-squat
jump exercise and agility characteristic in trained athletes. In accordance
with this purpose, 62 athletes (age: 20,9 ± 1,92 years; height: 178,1 ± 4,83
cm; weight: 71,2 ± 7,37 kg) who competed in the different sport brances (kick box,
karate, taekwondo, wrestling and football) participated voluntarily in this
study. Subjects were performed to illinois agility test and loaded-squat jump
exercise by using an external load corresponding to 40 % of their body weight
and velocity and power parameters were obtained as mean velocity (MV), mean
propulsive velocity (MPV) and peak velocity (PV), mean power (MP), mean
propulsive power (MPP) and peak power (PP). In the analysis of data;
descriptive statistics, Shapiro wilk test and pearson correlation anaylsis were
used. According to the analysis results;
average running times of participates in agility test was obtained as 15,8 (± ,51 sec). While velocity values during loaded squat jump
exercise were obtained as 1.38 (± ,08 m/s) for MV, 1.55 (± ,11 m/s) for MPV,
2.58 (± ,17 m/s) for PV; power values were obtained as 389,2 (± 51,6 W ) for
MP, 642,6 (± 118,1 W) for MPP, and 1119,4 (± 184,6 W) for PP. In addition it
was determined that there was a high-level, negative and statistically
significant difference between MV (r = - ,516; p<0.01), MPV (r = - ,434;
p<0.01), PV (r = - ,461; p<0.01), MP (r = - ,518; p<0.01), MPP (r = -
,487; p<0.01) and PP (r = - ,514; p<0.01) with running times in the agility test. Accordingly, as velocity and
power values during loaded squat jump exercise increases, running times in
agility test decreases. As a result, it can be suggested that velocity and
power values during loaded-squat jump exercise have a positive effects on
agility performance.

Antrenmanlı Sporcularda Çeviklik ve Ağırlıklı Squat Sıçrama Egzersizi Esnasındaki Hız ve Güç Değerleri Arasındaki İlişki

Abstract

Bu çalışmanın amacı;
antrenmanlı sporcularda çeviklik özelliği ve ağırlıklı squat sıçrama egzersizi
esnasındaki hız ve güç değerleri arasındaki ilişkinin araştırılmasıdır. Bu amaç
doğrultusunda, farklı branşlarda mücadele eden (kick boks, karate, taekwondo,
güreş ve futbol) 62 sporcu (yaş: 20,9± 1,92 yıl; boy: 178,1 ± 4,83 cm; kilo:
71,2 ± 7,37 kg) çalışmaya gönüllü olarak katıldı. Katılımcılara illinois çeviklik
testi ve vücut ağırlıklarının %40’ına karşılık gelen bir dış yük kullanılarak
ağırlıklı squat sıçrama egzersizi yaptırıldı ve ortalama hız (OH), ortalama
itme hızı (OİH), zirve hız (ZH), ortalama güç (OG), ortalama itme gücü (OİG) ve
zirve güç (ZG) değerleri elde edildi. Verilerin analizinde; tanımlayıcı
istatistik, Shapiro-Wilk testi ve pearson korelasyon analizi kullanıldı. Analiz sonuçlarına göre; katılımcıların
çeviklik testindeki ortalama koşu zamanları 15,8 (± ,51 sn) olarak elde edildi. Ağırlıklı squat sıçrama
egzersizi esnasındaki hız değerleri OH için 1.38 (± ,08 m/sn), OİH için 1.55 (±
,11 m/sn) ve ZH için 2.58 (± ,17 m/sn) olarak elde edilirken; güç değerleri ise
OG için 389,2 (± 51,6 W), OİG için 642,6 (± 118,1 W) ve ZG için 1119,4 (± 184,6
W) olarak elde edildi. Çeviklik testindeki koşu zamanları ile OH (r = - ,516;
p<0.01), OİH (r = - ,434; p<0.01), ZH (r = - ,461; p<0.01), OG (r = -
,518; p<0.01), OİG (r = - ,487; p<0.01) ve ZG (r = - ,514; p<0.01)
arasında yüksek düzeyde, negatif ve istatistiksel olarak anlamlı bir ilişki
olduğu elde edildi. Buna göre; ağırlıklı squat sıçrama egzersizindeki hız ve
güç değerleri arttıkça, çeviklik testindeki koşu zamanları azalmaktadır. Sonuç
olarak, ağırlıklı squat sıçrama egzersizi esnasındaki hız ve güç değerlerinin
çeviklik performansını olumlu yönde etkilediği ileri sürülebilir.
