THREE-DIMENSIONAL BIOMECHANIC ANALYSIS DURING A 2000M ROWING ERGOMETER TIME TRIAL

Öz

The aim of this study was to determine the fundamental characteristics of 2000m rowing technique in different distances (500m, 1000m, 1500m and 2000m). Ten elite rowers (age mean 20,90±1,5yrs; mean height 184,50±5,9cm; mean weight 79,40±9,05kg; mean training year 6,85±2,49yrs) were participated to this study. 2000m rowing techniques on Concept 2D ergometer was recorded by 2 high speed (100hz) Basler cameras and 500, 1000, 1500 and 2000m one circle of the rowing techniques were analyzed by using SIMI Motion Reality System Version 8.5.7. In catching and finishing phases segments’ angles, angular velocity, angular acceleration, stroke time, stroke power, stroke velocity and stroke rate were evaluated by SPSS 20.0 program. The differences between the performances were analyzed by one way ANOVA, the relationships between performance and kinematic parameters were evaluated by Pearson Correlation analysis. Significant differences were found at knee angle in catching phase (p<0.05); also, a statistically significant difference was found at every distance of the traction rate and this difference showed a gradual increase depending on the distance (p<0.05). As a result, it should not be forgotten that the important movements that accelerate the boat from traction are the chain movements created by the lower extremities, although they appear to be intensely occurring in the upper limbs of the body

Kürekçilerin Kürek Ergometresinde 2000 M Kürek Çekişlerinin 3 Boyutlu Biyomekaniksel Analizi

Öz

Araştırmanın amacı, 2000m kürek çekişinin farklı mesafelerinde (500m, 1000m, 1500m ve 2000m) kürek çekiş tekniğinin temel özelliklerinin tespit edilmesidir. Araştırmamıza yaş ortalaması 20,90±1,5yıl; boy ortalamaları 184,50±5,9cm ve ağırlık ortalamaları 79,40±9,05kg olan 10 erkek kürek sporcusu katılmıştır. Deneklerin 2000 m kürek çekiş performansları Concept 2D ergometresinde hızı 100 hz olan iki adet Basler marka video kamera ile kaydedilerek, 500, 1000, 1500 ve 2000 metrelik çekiş sonundaki bir kürek devri, SIMI Motion Reality Sistem versiyon 8.5.7 hareket analiz programında analiz edilmiştir. Yakalama ve bitiş fazlarında segmetlerin açı, açısal hız, açısal ivmeleri, kürek çekiş zamanı, çekiş gücü, çekiş hızı ve çekiş temposu verileri SPSS 20.0 programı kullanılarak istatistikleri yapılmıştır. Performanslar arasında elde edilen farklılıklar tek yönlü varyans analizi, performans ve kinematik parametreler arasındaki ilişkiler Pearson Korelasyon analizi ile değerlendirilmiştir. Diz açısında, yakalama fazında anlamlı farklılıklar bulunurken (p <0.05); çekiş hızının her mesafesinde istatistiksel olarak anlamlı bir farklılık bulunmuştur ve bu farklılık mesafeye bağlı kademeli bir artış göstermiştir (p<0.05). Sonuç olarak, çekiş anından tekneyi hızlandıran önemli hareketler, yoğun şekilde vücudun üst ekstremitelerinde gerçekleşiyormuş gibi gözükse de alt ekstremitelerin yarattığı bir zincir hareketinin olduğu unutulmamalıdır
