Examining the Coinciding-Anticipation Timing, Blood Lactate Level and Decision-Making of Football Referee at Different Exercise Intensities

Abstract

The study was conducted to examine the coinciding anticipation timing, blood lactate level and decision-making of football referees at different exercise intensities. Twelve male referees (6 referees and 6 asistant referees) who were all active in Mugla and had any health problems and injuries, participated in this study voluntarily. Low intensity exercise (%40), moderate intensity exercise (%60) and high intensity exercise (%90) were applied to the referees on the cycling ergometer on different days. The referees’ coinciding anticipation timing and decision-making skills about positions that occur very often in the match were measured at the target heart rate determined for each exercise intensity. In addition, blood lactate levels of referee were also examined before each exercise protocol and after exercise (1., 4 and 8. min). As a result of the statistical analysis, when the absolute error scores (6mph and 12 mph) measured during the low, moderate and high exercise intensity were compared, no statistically significant difference was found (p>0.05). In the comparison of measured decision-making skills during the low, moderate and high intensity exercise were found to be significant. A statistically significant difference was observed in the comparison of the blood lactate levels measured rest (before exercise), the 1st minute, 4th minute and 8th minute after exercise at all three exercise intensity (low, moderate, high). A statistically significant negative correlation was found between the blood lactate level measured at 8th minute after the low intensity exercise and total score of decision-making (r=.-577, p<0.05). Significant positive correlation were found between absolute error (6mph) measured high exercise intensity and blood lactate levels measured at 4th minute (r=.662, p<0.05)  and 8th minute (r=.741, p<0.05)  after high intensity exercise. In the planning of training programmes of the referees, , it is thought to be important to add the cognitive functions to the training programmes for the improving tolerance of exhaustion as well as the physical and physiological function.

Futbol Hakemlerinin Farklı Egzersiz Şiddetlerinde Sezinleme Zamanı, Kan Laktat Düzeyi ve Karar Verme Becerilerinin İncelenmesi

Öz

Bu çalışma, futbol hakemlerinin farklı egzersiz şiddetlerinde sezinleme zamanı, kan laktat düzeyi ve karar verme becerilerini incelemek amacıyla yapılmıştır.  Çalışmaya Muğla ilinde hakemlik yapan, herhangi bir sağlık problemi ve sportif yaralanması olmayan 12 erkek futbol hakemi (yardımcı hakem: 6, hakem: 6) gönüllü olarak katılmıştır. Çalışmaya katılan hakemlere, farklı günlerde bisiklet ergometresinde düşük şiddetli (%40) egzersiz, orta şiddetli (%60) egzersiz, yüksek şiddetli (%90) egzersiz protokolü uygulanmıştır. Hakemlerin her bir egzersiz şiddeti için belirlenen hedef kalp atım sayısında sezinleme zamanı ve maç içerisinde çok sık rastlanan pozisyonlarla ilgili karar verme becerileri egzersiz sırasında ölçülmüştür. Ayrıca hakemlerin her bir egzersiz öncesi ve egzersiz sonrasında (1., 4. ve 8. dk) kan laktat düzeyi incelenmiştir. İstatiksel analiz sonucunda; düşük, orta ve yüksek egzersiz şiddeti sırasında ölçülen mutlak hata skorları (6mph ve 12mph) karşılaştırıldığında, istatiksel olarak anlamlı farklılık bulunmamıştır (p>0.05). Düşük, orta ve yüksek şiddetteki egzersizler sırasında ölçülen karar verme becerilerinin karşılaştırılmasında istatiksel olarak anlamlı fark bulunmuştur (p<0.05). Her üç egzersiz şiddetinde de (düşük, orta, yüksek) egzersizden önce, egzersizden sonra 1. dakika, 4. dakika ve 8. dakikada ölçülen kan laktat düzeyinin karşılaştırılmasında istatiksel olarak anlamlı fark görülmüştür (p<0.05).  Düşük şiddetteki egzersizden sonra 8. dakikada ölçülen kan laktat düzeyi ile karar verme toplam skoru arasında istatiksel olarak negatif yönde ilişki bulunmuştur (r=.-577, p<0.05). Yüksek egzersiz şiddeti sırasında ölçülen mutlak hata skoru (6mph) ile egzersizden sonra 4. dakika (r=.662, p<0.05) ve 8. dakikada (r=.741, p<0.05) ölçülen kan laktat düzeyi değerleri arasında anlamlı ilişki bulunmuştur. Hakemlerin antrenman programlarının planlanmasında fiziksel ve fizyolojik özelliklerinin yanı sıra bilişsel fonksiyonlarının da yorgunluğa olan toleransını geliştirici egzersizlerin programa dahil edilmesinin önemli olduğu düşünülmektedir.
