The effects of 8-week core training on the development of some motoric features among 18 year-old footballers 18 yaş grubu futbolcularda 8 haftalik merkez bölge (core) antrenmanlarının bazı motorik özelliklerin gelişimine etkisi

The purpose of the present research is investigating the effects of core trainings on some motoric features (strength and speed) among 18 year-old footballers. In the present research, 20 experiment group (age =18 years, body weight =71,66±6,61 kg, height =171,75±5,86 cm) and 20 control group (age =18 years, body weight =70,66±5,74 kg, height =171,75±2,99 cm), the total of 40 certified footballers, who played in 2013-2014 season, participated in the present research. Before the trainings, pre-test scores (sit-up, push-up, plank, vertical jump, medicine ball throwing, 30 m speed) were recorded. 30-35 minute core trainings, 2 days a week, for 8 weeks were conducted on the control group in addition to their regular training. Control group participants followed their regular yearly training program. At the end of the trainings, post-test scores of both groups were recorded by two experts in the field in accordance with the protocol. In order to evaluate the effects of 8-week core trainings of the strength development of footballers, paired t test was utilized for in-group comparisons and independent samples t test was utilized for inter-group comparisons. Consequently, it was observed that 8-week core training in addition to football trainings contributed to the strength and speed development among footballers. Accordingly, core trainings can be advised for football trainers, who work for youth teams of football clubs. Ozet Bu arastirmanin amaci 18 yas grubu futbolcularda bolgesel (core) antrenmanlarin bazi motorik ozelliklerin (kuvvet ve surat) gelisimine etkisinin incelenmesidir. Arastirmaya 2013-2014 sezonunda lisansli olarak futbol oynayan 20 denek grubundan (yas =18 yil, vucut agirligi =71,66±6,61 kg, boy =171,75±5,86 cm) ve 20 kontrol grubundan (yas =18 yil, vucut agirligi =70,66±5,74 kg, boy =171,75±2,99 cm) olmak uzere 40 futbolcu katildi. Antrenmanlar oncesi gruplarin on testleri (mekik, sinav, plank, dikey sicrama, saglik topu firlatma, 30 m. surat) alindi. Deney grubuna normal antrenmanlarina ek olarak 8 hafta boyunca haftada 2 kez gunde 30-35 dk. core antrenmanlar uygulandi. Kontrol grubuna ise yillik antrenman programinda yer alan olagan antrenmanlar uygulandi. Antrenmanlar sonunda gruplarin son test olcumleri alaninda uzman iki kisi tarafindan protokole uygun bir sekilde alindi. 8 hafta boyunca uygulanan merkez bolge (core) antrenmanlarinin futbolcularin kuvvet gelisimine etkisinin degerlendirilmesinde grup ici karsilastirmalarda paired t testinden gruplar arasi karsilastirmalarda independent sample t testinden yararlanilmistir. Sonuc olarak; futbol antrenmanlarina ek olarak uygulanacak 8 haftalik merkez bolge (core) antrenmanlarinin futbolcularin kuvvet ve surat gelisimine katki sagladigi goruldu. Bu nedenle bolgesel (core) antrenman alt yapilarda calisan futbol antrenorlerine onerilebilir.
