Comparison of the Reactive Agility and Preplanned Change of Direction Abilities of the Elite and Sub Elite Young Karate Players

Abstract

The purpose of this study was to compare elite and sub-elite young karate players’ reactive agility and preplanned change of direction abilities regulated considering their punches. Thirteen elite (age: 14.92±1.65 height:157.53±9.07cm, weight: 52.92±9.86kg) and 10sub-elite (age: 13.50±0.52, height:153.00±7.22cm, weight: 54.40±9.93kg) young karate players participated in the current study. Four infrared sensors were placed on four different points of the sandbag for the purpose of determining reactive agilities of the players during their punching. Led light was present on the sensors. One of these sensors was turned on by the researcher by being triggered. The player punched under the sensor for becoming active, the sensor detected the punch when it was thrown out and it triggered on another sensor. As the player turned off four led lights in total, the test ended. The player did not know which sensor became active in this test. A different course was set for each player. In preplanned change of direction test, the players knew which sensor will be triggered respectively. With the start, when punches were thrown out under four led lights respectively, the test ended. Independent variable t-test was used for comparing the results of two tests among the groups. Pearson correlation analysis was used to determine the relationship between the tests. As a consequence of the study, the reactive agility values of the elite players were statistically lower (2.567±0.50 sec. vs. 3.469±0.77sec. p<0.05) while a meaningful difference was not found between their preplanned change of direction. In addition, there was high positive correlation between two tests (r= 0.874, p<0.05). In conclusion, it was suggested that reactive agility exercises should be included in trainings of the martial sports.

Elit ve Subelit Genç Karatecilerin Reaktif Çeviklik ve Planlı Yön Değiştirme Becerilerinin Karşılaştırılması

Öz

Bu çalışmanın amacı elit ve sub-elit genç karatecilerin yumruk vuruşlarına göre düzenlenmiş reaktif çeviklik ve planlı yön değiştirme becerilerinin karşılaştırılmasıdır. Çalışmaya on üç elit (yaş:14.92±1.65 yıl  , boy:157.53±9.07 cm., kilo:52.92±9.86 kg) ve on sub-elit (yaş:13.50± 0.52 yıl,  boy:153.00±7.22 cm, kilo:54.40±9.93 kg) genç karateci katılmıştır. Sporcuların yumruk atışları esnasındaki reaktif çevikliklerinin belirlenmesi amacıyla kum torbasının dört ayrı noktasına dört kızılötesi sensör yerleştirilmiştir. Sensörlerin üzerinde led ışık bulunmaktadır. Bu sensörlerden biri araştırmacı tarafından tetiklenerek açılır. Sporcu ışığı aktifleşen ledin altına yumruk atar yumruk atıldığında sensör yumruğu algılar ve diğer ledi yakar. Sporcu toplamda dört ledi söndürdüğünde test sona erer. Sporcu bu testte hangi sensörün aktifleşeceğini bilmemektedir. Her sporcu için farklı rota belirlenmiştir. Planlı yön değiştirme testinde ise bu sefer sporcular hangi sensörün altına sırasıyla yumruk atacaklarını bilmektedir. Startla beraber sırasıyla dört ledin altına yumruk atışı yapıldığında test sona ermiştir. Her iki testin sonucunun gruplar arasında karşılaştırılması amacıyla bağımsız değişken t testi kullanılmıştır. Testler arasındaki ilişkinin belirlenmesi için Pearson korelasyon analizi uygulanmıştır. Çalışma sonunda elit sporcuların reaktif çeviklik değerleri istatistiksel olarak daha kısa iken (2.567±0.50sn. karşın 3.469±0.77sn., p<0.05), planlı yön değiştirme becerileri arasında anlamlı fark tespit edilememiştir.  Bununla beraber, iki test arasında pozitif yönde yüksek bir ilişki tespit edilmiştir (r= 0.874, p<0.05). Sonuç olarak; dövüş sporlarında antrenmanlarda reaktif çeviklik çalışmalarına yer verilmesi önerilmektedir.
