Abstract

Bu çalışmanın amacı 8 haftalık farklı pozisyonlarda uygulanan squat antrenmanlarının diz fleksiyon ve ekstansiyon kuvvet gelişimine etkilerini araştırmaktır. Bu çalışmaya 33 sağlıklı erkek denek gönüllü olarak katıldı. Denekler tesadüfi yöntemle tam squat grubu (TSG, n=11), yarım squat grubu (YSG, n=11), ve kontrol grubu (KG,n=11) olarak üç gruba ayrıldı. Deney grubundaki (TSG ve YSG) deneklere haftada üç gün, toplam sekiz hafta süreli, 1 Maksimum tekrarlarının % 60’ı şiddetinde tam ve yarım squat egzersizleri yaptırıldı. Çalışma ağırlıkları 4. haftadan sonra yeniden ayarlandı. Deneklerin yaş, boy ve vücut ağırlığı ortalamaları sırasıyla, Tam squat grubunda 21,45 ± 1,57 yıl, 179,36 ± 5,18 cm , 70,90 ± 6,68 kg., Yarım squat grubunda 21,18 ± 1,25 yıl, 176,90 ± 5,41 cm., 70,04 ± 7,36 kg., Kontrol grubunda ise 21,90 ± 0,70 yıl, 174,45 ± 7,35cm., 72,36 ± 6,29 kg. olarak tespit edilmiştir. Elde edilen verilerin analiz ve değerlendirilmesi SPSS 10.0 istatistik paket programıyla Tek Yönlü Varyans Analizi ve Tukey testleri ile yapıldı. Anlamlılık düzeyi olarak 0,05 ve 0,01 kabul edilmiştir. Sonuç olarak; yarım squat egzersizlerinin diz ekstensör ve fleksörlerinin kuvvet gelişiminde daha etkili olduğu söylenilebilir

Abstract

The purpose of this study is to assess effects of squat exercises in different positions (half and full squat) on knee flexion and extension strength development. 33 Healthy male subjects were voluntarily participated in to this study. Subjects were divided in to three groups such as full Squat group (FSG,n=11),half squat group (HSG,n=11) and control group (CG,n =11).Subjects in FSG and HSG trained total 8 weeks, three times in a week with 60% of their 1RM . Working weights of subjects were adjusted according to their strenght development after 4 weeks.Control group had no exercise regime.Age ,height and weight of subjects participated in to this study 21,45 ± 1,57 years, 179,36 ± 5,18 cm , 70,90 ± 6,68 kg. in FSG, 21,18 ± 1,25 years, 176,90 ± 5,41 cm., 70,04 ± 7,36 kg. in HSG and 21,90 ± 0,70 years, 174,45 ± 7,35cm., 72,36 ± 6,29 kg. in CG respectively. Statistical analysis were done by using one-way ANOVA and Tukey in SPSS 10,0 Package Program. 0,01 and 0,05 Were taken as meaningfull level. As a result of this study it could be said that half squat exercises has more effects than full squat exercises to improve the strenght of leg flexors and extensors
