INVESTIGATION OF RELATIONSHIP BETWEEN DIFFERENT DISTANCE ROLLER SKIING PERFORMANCE AND ANAEROBIC POWER IN CROSS COUNTRY SKIERS

Abstract

The main objective of this study is to determine the relationship between roller ski sprint exercise and anaerobic power in cross country skiers. Ten volunteered male skiers with ages of 19.3±2.5 year, heights of 173.3±6.2 cm and weights of 67.6±8.4 kg attended to the study. Firstly 200 m, 400 m and 800 m maximal exercise measurements with roller ski were performed in a 400 m outdoor tartan track and then anaerobic leg strength measurements were performed in the laboratory using 30-second Wingate Cycle Ergometer Test Protocol. Statistical analysis was conducted by using the Graph Pad Prism Version 5.00 for Windows (Graph Pad Software, San Diego California USA) program and Spearman Range-Correlation Test was performed. The value of p<0.05 was accepted for statistical significance. As a results: while a significant positive correlation was observed between 200m roller ski exercise and peak power (r= -0,976 ), a significant positive correlation was found between 800 m exercise and average power (r= -0.960). There were similar significant correlation for 400 m both of peak power ( r= -0.760 ) and average power(r= -0.796).

ELİT SEVİYEDEKİ KAYAKLI KOŞUCULARIN FARKLI MESAFELERDEKİ TEKERLEKLİ KAYAK PERFORMANSLARI İLE ANAEROBİK GÜÇLERİ ARASINDAKİ İLİŞKİNİN İNCELENMESİ

Öz

Bu çalışmanın amacı kayaklı koşu sporcularının tekerlekli kayak kullanarak yaptıkları farklı mesafelerdeki sprint egzersizinin anaerobik güç üzerine etkisini incelemektir. Araştırmaya yaşları 19.3±2.5 yıl, boyları 173.3±6.2 cm ve ağırlıkları 67.6±8.4 kg olan 10 gönüllü erkek kayaklı koşucu katılmıştır. 200 m, 400 m ve 800 m tekerlekli kayakla maximal egzersiz ölçümleri açık alan tartan pistte, anaerobik bacak kuvveti ölçümleri ise laboratuarda Wingate 30-sn Bisiklet Ergometre Testi kullanılarak yapılmıştır. Çalışmanın istatistiksel analizi GraphPad Prism Version 5.00 programında Spearman Korelasyon Testi ile yapılmıştır. Araştırmanın sonucunda 200 m tekerlekli kayak egzersizi ile zirve güç arasında pozitif korelasyon (r= -0,976 ) gözlenirken, 800 m uygulanan egzersiz ile de ortalama güç arasında belirgin pozitif korelasyon (r= -0.960) bulunmuştur. 400 m de ise zirve güç ( r= -0.760 ) ve ortalama güç (r= -0.796) ilişkisi oldukça benzer sonuçlar ortaya koymuştur. Sonuç olarak kayaklı koşu sprint yarışma mesafeleri dikkate alındığında en iyi performans için ortalama anaerobik güç parametresinin daha etkin olabileceği söylenebilir.
