How Does Core Strength Training Affect Balance and Some Physical Performance Parameters in Hearing Impaired Individuals ?

Abstract

The purpose of the study was to investigate the effects of core strength training (CST) on the balance and physical performance parameters in deaf individuals. Thirty deaf students participated. The subjects were randomly separated into two groups as experimental (EG: 15; 4 female 11 male; age: 19.60±1.96) and control group (CG: 15; 4 female 11 male; age: 19.73±1.03). A four-week CST program was implemented in the EG. The CG subjects only participated in their daily life. Height, body weight, balance, flexibility, right-left hand grip strength, vertical jump, standing long jump, push-up and curl-up tests were applied to all subjects baseline and after four-week program. 2x2 mixed factor ANOVA test was performed. Flexibility, right-left hand grip strength, standing long jump, vertical jump, push-up and curl-up variables significantly improved after a 4-week period in the EG (p<0.05). Only the left hand grip strength and curl-up variables were significantly changed (p<0.05) in CG. The mean differences showed significant alterations in flexibility, right hand, vertical jump and push-up parameters in favor of EG (p<0.05). In addition, balance ability improved by 12.73% in EG while it decreased by 9.37% in CG. In conclusion, CST was effective in improving body balance and physical performance parameters in hearing-impaired individuals. This result is thought to occur with the increase in strength of the muscles in the core area. It is recommended to include CST in exercise programs for the hearing impaired.

Core Kuvvet Antrenmanı İşitme Engelli Bireylerin Denge ve Bazı Fiziksel Performans Parametrelerini Nasıl Etkiler?

Öz

Araştırmanın amacı core kuvvet antrenman (CKA) modelinin işitme engelli bireylerin denge ve fiziksel performansları üzerine etkilerini incelemektir. Araştırmaya 30 işitme engelli öğrenci katıldı. Katılımcılar, egzersiz grubu (EG: 15; 4 kadın 11 erkek; yaş: 19,60±1,96) ve kontrol grubu (KG: 15, 4 kadın 11 erkek; yaş: 19,73±1,03) olarak rastgele iki gruba ayrıldı. EG’ye dört haftalık (haftada 5 gün) CKA programı uygulandı. KG’deki katılımcılar sadece günlük yaşamlarına devam ettiler. Tüm katılımcılara antrenman uygulaması başında ve sonunda boy uzunluğu, vücut ağırlığı, denge, esneklik, sağ-sol el kavrama kuvveti, dikey sıçrama, durarak uzun atlama, şınav ve mekik testleri uygulandı. Grup içi ve gruplar arası farkları karşılaştırmak için 2x2 mixed faktör ANOVA kullanıldı. Dört haftalık CKA programı sonrası EG’de esneklik, sağ-sol el kavrama kuvveti, durarak uzun atlama, dikey sıçrama, şınav ve mekik testi değişkenlerinde anlamlı gelişim görüldü (p<0,05). KG’de ise sadece sol el kavrama kuvveti ve mekik değişkenlerinde anlamlı değişim oldu (p<0,05). EG ve KG’nin ön-son testleri arasındaki ortalama farklar karşılaştırıldığında esneklik, sağ el kavrama, dikey sıçrama ve şınav parametrelerinde EG lehine anlamlı farklılık görüldü (p<0,05). Ayrıca denge yeteneği EG’de %12,73 gelişim gösterirken KG’de %9,37 gerileme gösterdi. Sonuç olarak CKA modeli, işitme engelli bireylerde denge ve fiziksel performans parametrelerinin gelişiminde etkili olduğu söylenebilir. Bu sonucun core bölgesindeki kasların kuvvet artışıyla meydana geldiği düşünülmektedir. İşitme engellilerin egzersiz programlarına CKA’nın da dahil edilmesi önerilmektedir.
