Çeşitli Kick Boks Anaerobik Hız Testi Varyasyonlarının Deneyimli ve Başlangıç Seviye Kick Boks Sporcularını Ayırt Etmedeki Etkinliği: Bir Diskriminant Fonksiyon Analizi

Abstract

Kick Boks Anaerobik Hız Testi (Kickboxing Anaerobic Speed Test, KAST), kick boks sporu için özel olarak geliştirilmiş bir performans değerlendirme testidir ancak başlangıç seviyesindeki ve deneyimli sporcuları ayırt etmedeki etkinliği üzerine sınırlı bilgi bulunmaktadır. Bu çalışmanın amacı, farklı tekrar sayılarına sahip tekli ve çoklu KAST'ların, başlangıç seviyesindeki ve deneyimli kickboksçuları ayırt etmedeki etkinliğini araştırmaktır. Çalışmaya gönüllü olarak katılan 24 kickboksçu Deneyimli Grup ([DG] yaş: 21,5 ± 2,7 yıl; boy: 173,5 ± 3,4 cm; vücut kütlesi: 66,6 ± 5,9 kg; vücut kitle indeksi [VKİ]: 22,08 ± 1,3; antrenman yaşı: 8,4 ± 1,5 yıl) ve Başlangıç Grubu ([BG] yaş: 20,8 ± 2,0 yıl; boy: 172,6 ± 4,2 cm; vücut kütlesi: 67,0 ± 6,5 kg; VKİ: 22,44 ± 1,4; antrenman yaşı: 2,7 ± 1,1 yıl) olarak gruplara ayrılmıştır. Katılımcılara hem tekli hem de çoklu KAST varyasyonları uygulanmıştır. İstatistiksel analizler SPSS 27 yazılımı ile gerçekleştirilmiş ve anlamlılık düzeyi p<0,05 olarak kabul edilmiştir. Yaş, boy, vücut kütlesi ve VKİ gruplar arasında anlamlı fark göstermemiştir (p>0,05). Ancak, antrenman yaşı anlamlı derecede daha yüksek bulunmuş (p<0,001) ve KASTmaks, KASTtoplam ve tüm KAST setleri (Birinci setten beşinci sete kadar) DG'de BG'ye göre anlamlı derecede daha düşük bulunmuştur (p<0,001). Ayrıca, diskriminant fonksiyon analizleri, KASTtoplam’ın grupları %91,7 oranında doğru sınıflandırırken, KASTmaks’ın grupları %83,3 oranında doğru sınıflandırdığını göstermiştir. Kick Boks Anaerobik Hız Testi (KAST), kickboksçuların performans seviyelerini değerlendirmede güvenilir bir ölçüt olarak hizmet etmektedir. Bununla birlikte, beş setlik toplam KAST, tek setlik en iyi skor KAST'a kıyasla daha yüksek ayırt edici geçerliliğe sahiptir.

The Effectiveness of Different Kickboxing Anaerobic Speed Test Variations in Distinguishing Experienced And Novice Kickboxers: A Discriminant Function Analysis

Abstract

The Kickboxing Anaerobic Speed Test (KAST) is a performance assessment test developed specifically for kickboxing; however, there is limited information regarding its effectiveness in distinguishing between novice and experienced athletes. The aim of this study was to investigate the efficacy of single and multiple KASTs, administered with varying repetition numbers, in distinguishing between novice and experienced kickboxers. A total of 24 kickboxers voluntarily participated to this study and they were assigned to experienced group ([EG] age: 21.5 ± 2.7 years; height: 173.5 ± 3.4 cm; body mass: 66.6 ± 5.9 kg; body mass index [BMI]: 22.08 ± 1.3; training age: 8.4 ± 1.5 years) and novice group ([BG] age: 20.8 ± 2.0 years; height: 172.6 ± 4.2 cm; body mass: 67.0 ± 6.5 kg; BMI: 22.44 ± 1.4; training age: 2.7 ± 1.1 years). The study participants were administered both single and multiple variations of the KAST. Statistical analyses were performed with the SPSS 27 software and the significance level was accepted as p<0.05. Age, height, body mass, and BMI did not significantly differ between the groups (p>0.05). However, training age was significantly higher (p<0.001) and KASTbest, KASTmultiple and all KAST sets (first to five) were significantly lower in the EG than BG (p<0.001). Moreover, discriminant functions analyses showed that KASTmultiple classified groups correctly by %91.7 while KASTbest classified groups correctly by %83.3. The Kickboxing Anaerobic Speed Test (KAST) stands as a reliable metric for assessing kickboxers' performance levels. However, a five-set multiple KAST offers greater discriminative validity than its single-set counterpart.
