The Comparison of the Effects of Post-Activation Performance Enhancement Constituted by Back Squat and Hip Thrust on Vertical Jump and Sprint Performances of Well-Trained Male Athletes

Abstract

The aim of this study was to compare the acute effects of post activation performance enhancement (PAPE) generated by back squat (BS) and hip thrust (HT) exercises on vertical jump and sprint performances. Twelve male athletes, who could perform BS exercises at least 1.5 times of their body mass, voluntarily participated in this study (age: 21.6 ± 2.6 8; height: 192 ± 7.30 cm; body mass: 86.7 ± 11.1 kg; body fat ratio: 8.7 ± 3.6%). Athletes’ vertical jump and 30 meter sprints were performed at four separate days with and without prior exercises using cross over study design. 5 sets × 1 repeat protocol c orresponding to athletes’ 90% of 1 RM was used during HT and BS applications. According to results, PAPE created by BS did not significantly effect on sprint performance (p>0.05; ES=0.40); however, BS applications significantly enhanced vertical jump perfo rmances (p=0.005; ES=1.02). Neither vertical jump nor sprint performance of athletes were significantly affected by HT applications (p>0.05; ES=0.35; ES=0.09). As a result, PAPE performed by BS significantly enhanced only vertical jump performances of athletes.

Geriye Çömelme ve Kalça İtiş Egzersizleriyle Oluşturulan Aktivite Sonrası Performans Artışının İyi Antrene Erkek Sporcuların Dikey Sıçrama ve Sprint Performanslarına Etkilerinin Karşılaştırılması

Abstract

Bu çalışmanın amacı, geriye çömelme (GÇ) ve kalça itiş (Kİ) egzersizleri yoluyla oluşturulan ön yüklerin yaratacağı aktivite sonrası performans artışının (ASPA) dikey sıçrama ve sprint performansına akut etkilerini karşılaştırmaktır. Çalışmaya vücut kütlesinin 1,5 katıyla GÇ egzersizleri uygulayabilen iyi antrene 12 erkek sporcu gönüllü olarak katılmıştır (yaş: 21,6±2,68; boy: 192±7,30 cm; vücut kütlesi: 86,7±11,1 kg; vücut yağ oranı: % 8,7±3,6). Sporcuların dikey sıçrama ve 30 metre sprint performansları GÇ ve Kİ ile oluşturulan ön yükler uygulanarak ve uygulanmadan dört farklı günde ve çaprazlanarak gerçekleştirilmiştir. GÇ ve Kİ uygulamalarında sporcuların 1 TM’nin %90’ı ile 5 set × 1 tekrarlık egzersizler kullanılmıştır. Elde edilen bulgulara göre; GÇ ile oluşturulan ASPA sprint performansını anlamlı ölçüde etkilememiştir (p>0,05; ES=0,40). Diğer yandan GÇ uygulamaları dikey sıçrama performansını anlamlı ölçüde arttırmıştır (p=0,005; E S=1,02). Kİ ile oluşturulan ön yük sonrasında ise ne dikey sıçrama ne de sprint performanslarındaki artış anlamlıdır (p>0,05; ES=0,35; ES=0,09). Sonuç olarak, GÇ yoluyla oluşturulan ASPA, sporcuların yalnızca dikey sıçrama performansı artışında etkili olmu ştur.
