AKTİF FUTBOL OYUNCULARININ ÇEŞİTLİ DENGE PARAMETRELERİNİN DEĞERLENDİRİLMESİ

Öz

Aktif futbol oyuncuları ile sedanterlerin çeşitli denge parametrelerinin karşılaştırıldığı bu çalışmada, 40 sağlıklı gönüllüden, 20’si futbol oynayanlar grubunu ve 20’si kontrol grubunu oluşturdu. Gönüllüler 18 ve 25 (ortalama 21.4 ± 1.3) yaşlar arasında, erkek, alışkanlık yapan bir madde kullanımı bulunmayan, kalp, dolaşım, solunum ve nörolojik şikayetleri olmayan sağlıklı kişilerden seçildi. Deneklerin postural salınımı güç platformu üzerinde tek ve çift ayak üzerinde, gözler açık ve kapalı olarak ölçüldü. Ölçümler çıplak ayak ile 180 saniye süreyle yapıldı. Denge parametreleri deney ve kontrol gurupları arasında karşılaştırıldı. Ölçümlerde elde edilen veriler, anterio-posterior ve medial-lateral eksenlerde ayrı ayrı olmak üzere maksimum hız, maksimum ivme, dominant frekans pik değeri ve eksen boyunca meydana gelen salınım eğrisinin fraktal boyutu yönünden istatistiksel olarak değerlendirildi. Sonuç olarak, istatistiksel veri analizi iki grup arasında maksimum hız ve ivmelenme parametrelerinde farklılık olduğunu gösterdi. Futbol oynayan grubun kontrol grubuna göre daha düşük maksimum hıza ve daha düşük maksimum ivmelenmeye sahip olduğu görüldü. Maksimum hız ve maksimum ivmelenme açısından istatistiksel olarak anlamlı farklılık gösteren hemen bütün pozisyonlarda, fraktal boyut değerlerinde de anlamlı farklılık bulundu (p<0,05). Dominant frekans pik değeri açısından sadece medial-lateral eksendeki salınımın frekans komponentinde farklılığın istatistiksel önem taşıdığı saptandı (p<0,05)

The Different Balance Parameters Evaluation of the Active Soccer Players

Öz

The aim of this study was to compare the difference between balance the parameters of active soccer players and sedentary volunteers of healthy volunteers, 20 were assigned to soccer players group and 20 to a control group. Volunteers were selected from among the subject who are all male aged from 18 to 25 (mean: 21.4±1.3) and have no complaints about cardiovascular, respiratory and neurologic system. Postural sway was measured using of a force platform subject standing on which bipedal and unipedal, eyes open and closed. The test was performed with the shoes off. The total duration of the test was 180 seconds. Balance parameters were compared between soccer players group and control group. The measured values were statistically evaluated with a significant level (p<0,05) on the anterior-posterior and mediallateral axis separetely according to maximum velocity, maximum acceleration, dominat frequency peak values and fractal dimension. In conclution, data analysis revealed that there were significant differences between groups when maximum velocity and maximum acceleration were compared. Soccer players group had a lower maximum velocity and maximum acceleration than those in the control groups at all positions. There was also a significant difference at fractal dimension values at all positions in terms of maximum velocity and maximum acceleration (p<0.05). There was a statistically significant difference at the frequency component of the sway on medial-lateral axis in terms of dominat frequency peak values (p<0.05)
