RELATIONSHIP BETWEEN BODY COMPOSITION, LEG VOLUME, LEG MASS, ANAEROBIC PERFORMANCE AND KNEE STRENGTH IN CLIMBERS

Öz

The purpose of the present study was to investigate the relationship between body composition, leg volume, leg mass, anaerobic performance and knee strength in climbers. 59 climbers from university students participated in this study voluntarily (Xage: 21.93 ± 2.07 yrs). For the determination of body composition, subjects’ height, body weight and skinfold thickneses were taken and body fat percentage was determined by the Jackson & Pollock formula (1978). Circumferential measurements were used for the determination of leg volume. Leg mass was determined by the Hanavan Method, Wingate Anaerobic Power Test (WanT) was used for the determination of anaerobic performance and Isometric Knee Dynamometer was used for the determination of knee strength. Results of Pearson Product Moment correlation analysis, leg volume was significantly correlated with body fat percentage (r=.310; p<0.01), fat mass (r=.400; p<0.01), lean body mass (r=.456; p<0.01), leg mass (r=.833; p<0.01), peak power (r=.558; p<0.01) and mean power (r=.508; p<0.01). Body fat percentage was significantly correlated with peak power (r=.405; p<0.01). Similarly leg mass was significantly correlated with peak power (r=.438; p<0.01) and mean power (r=.510; p<0.01). In addition, lean body mass (LBM) was found to be significantly correlated with peak power (r=.425; p<0.01) and mean power (r=.650; p<0.01). Results also indicated that knee strength was significantly correlated with peak power (r=.720; p<0.01) and mean power (r=.664; p<0.01). As a conclusion, the findings of the present study indicated that leg volume and leg mass plays important role in anaerobic performance in climbers. Isometric knee strength was found to be correlated with anaerobic performance

DAĞCILARDA VÜCUT KOMPOZİSYONU, BACAK HACMİ, BACAK KÜTLESİ, ANAEROBİK PERFORMANS VE BACAK KUVVETİ ARASINDAKİ İLİŞKİ

Öz

Bu çalışmanın amacı dağcılarda vücut kompozisyonu, bacak hacmi, bacak kütlesi, anaerobik performans ve bacak kuvveti arasındaki ilişkinin belirlenmesidir. Çalışmaya toplam 59 gönüllü (Xyaş: 21.93±2.07 yıl) erkek üniversite öğrencisi katılmıştır. Araştırma grubunun vücut kompozisyonunun belirlenmesinde; boy uzunluğu, vücut ağırlığı, deri kıvrım kalınlığı, yağ yüzdesinin belirlenmesinde Jackson ve Pollock (1978) formülü kullanılmıştır. Bacak hacmi çevre ölçümleri ile bacak kütlesi Hanavan yöntemi ile anaerobik performans ise Wingate anaerobik güç ve kapasite testi ile belirlenirken, bacak kuvveti belirlemek için ise İzometrik bacak kuvveti dinamometresi kullanılmıştır. Yapılan Pearson Çarpımlar Moment Korelasyon sonucunda elde edilen bacak hacmi ile vücut yağ yüzdesi (r=.310; p<0.01), yağ kütlesi (r=.400; p<0.01), yağsız beden kütlesi (r=.456; p<0.01), bacak kütlesi (r=.833; p<0.01), pik güç (r=.558; p<0.01), ortalama güç (r=.508; p<0.01) arasında anlamlı ilişki bulunmuştur. Ayrıca vücut yağ yüzdesi ile pik güç (r=.405; p<0.01) arasında da anlamlı ilişki bulunmuştur. Bu benzerlik bacak kütlesi ile pik güç (r=.438; p<0.01), ortalama güç (r=.510; p<0.01) arasında da bulunmuştur. Bu sonuçlara ek olarak yağsız beden kütlesi ile pik güç (r=.425; p<0.01) ve ortalama güç (r=.650; p<0.01), arasında da ilişki bulunmuştur. Sonuçlar göstermiştir ki bacak kuvveti ile pik güç (r=.720; p<0.01) ve ortalama güç (r=.623; p<0.01) arasında anlamlı pozitif ilişki bulunmuştur. Sonuç olarak, çalışmadaki bulgular dağcıların bacak hacminin ve bacak kütlesinin anaerobik performanslarında belirleyici rol aldığını göstermiştir. Ayrıca izometrik bacak kuvveti ile anaerobik performans arasında da ilişki bulunmuştur
