GÖVDE ÇALIŞMA ARACI İLE GÖVDE EKSTANSÖRLERİ İÇİN GELENEKSEL EGZERSİZLERİN KARŞILAŞTIRILMASI VE GENÇ ERİŞKİNLERİN DURUŞ FAZINDA AĞIRLIK DAĞILIMI ÜZERİNE ETKİSİ: PİLOT ÇALIŞMA

Abstract

Amaç: Bu çalışma gövde çalışma aracı (GÇA) ve gövde ekstansörleri için geleneksel egzersizlerin (GEGE) aynı paternde uygulanması sırasında multifidus ve erector spinae kas aktiviteleri arasında bir fark olup olmadığını tespit etmek ve sırasıyla GÇA ve GEGE ile uygulanan programın ardından gruplar arasında ağırlık aktarmada postüral değişiklikleri araştırmak amacıyla planlanmıştır.

Yöntemler: Çalışmaya yaş ortalaması 24.5±3.7yıl olan 20 sağlıklı erkek katılmıştır. İlk gün tüm katılım- cılar GÇA ve GEGE egzersizlerini yaparken kas EMG aktiviteleri kaydedilmiştir. Ertesi gün katılımcılar iki gruba ayrılmıştır. GÇA (n=10) ve GEGE grubu (n=10) 5 kez çalışmışlardır. Vücut ağırlık dağılımı eğitim sürecinden önce ve sonra ölçülmüştür.

Sonuçlar: Toplam GÇA ve GEGE çalışma sonuçları arasında istatistiksel olarak anlamlı bir fark bulun- muştur (p=0,00). Her iki grupta da çalışma öncesi ve sonrası iki bacağın ağırlık dağılımları arasında anlamlı bir fark bulunmamasına rağmen, GEGE grubundan daha fazla olduğu göze çarpan, GÇA grubunda her iki bacak için değerlerin standart sapma ve frekanslarında anlamlı bir fark bulunmuştur (p=0.00).

Tartışma: Sonuç olarak, GEGE ile karşılaştırıldığında GÇA çalışmasının daha az kas aktivitesi, dolayısıyla daha az enerji tüketimi gerektirdiği ve aynı sürede daha iyi sonuç durumuna ulaştırdığı görünmektedir. GÇA çalışmasının gövde ağırlık dağılımı üzerine etkisini açıkça ortaya çıkarabilmek için ileriki çalışmalar- da daha fazla katılımcıya ihtiyaç olduğu düşünülmüştür. Ayrıca geriatrik veya nörolojik bozukluğu olanlar gibi diğer popülasyonlarda bu alanda yeni çalışmaların planlanması önerilmektedir.

Comparison Between a Trunk Training Machine and Conventional Exercises For Trunk Extensors and Effect on Stance Weight Distribution of Young Adults: A Pilot Study.

Öz

Purpose: The aim of this study was to determine if there was a difference between activities of multifi- dus and erector spinae muscles, when trained using the same patterns through a trunk training machine (TTM) and conventional exercises for trunk extensors (CETE), and to investigate the postural changes in weight bearing between groups after interventions of TTM and CETE, respectively.

Methods: 20 healthy males with a mean age of 24.5±3.7 years participated in the study. First day, muscle EMG activities were recorded while all of the participants performed TTM and CETE exercises. Next day, they were separated into two groups. TTM (n=10) and CETE groups (n=10) were trained for 5 bouts. The body weight distribution was measured before and after the training periods.

Results: There was a significant difference between total TTM-Work output and CETE-Work output (p<0.01). Although no significant differences were found between two legs’ weight distribution in both groups before and after the intervention program, standard deviation and frequencies of the values in TTM group for both legs were significantly different, and higher than CETE group (p=0.00).

Discussion: In conclusion, the TTM training appears to demand less muscle activity, thus less energy consuming and produced better stance outcome in the same time when compared with CETE. It is sug- gested that more participants are needed for a further research to reveal the effect of TTM intervention on the body weight distribution clearly. It is also recommended to plan new research in this field on other populations such as geriatrics or neurological disorders.
