ELİT FUTBOLCULARIN SABAH VE AKŞAM ANTRENMANLARINDAKİ KOŞU PARAMETRELERİNİN KARŞILAŞTIRILMASI

Abstract

Purpose: Although there are many studies in the literature regarding the running of soccer players,
 there is a need to examine the running asymmetry of the athletes' actual training, regardless of
 a specific intervention protocol. The aim of this study was to compare the running asymmetry of
 healthy elite soccer players in training sessions at different times of the day.
 Methods: Sixteen healthy male elite soccer players were included in this study. Global Positioning
 System units (GPSports, SPI Pro, 5 Hz, GPSport, Canberra, Australia) were used to define training
 and running details. Fourteen (7 morning, 7 evening) training data were evaluated.
 Results: There was no statistical difference between morning and evening trainings in terms
 of training time, heart rate average and total running distance except for high speed running
 distance. Running asymmetry was 66% greater in evening training sessions than in morning
 training sessions (p=0.001; 4.13±1.92, 2.49±1.32 respectively). Running asymmetry did not show
 any significant correlation with training time, heart rate average, running distance, and high speed
 running distance (p>0.05).
 Conclusion: Running asymmetry is higher in evening training sessions than in morning training
 sessions. Therefore, for athletes who are particularly at high risk of injury or who are in the process
 of a return to sports, and from whom high performance is not expected, morning trainings may be
 preferred instead of evening trainings. If training can not be performed in the morning, clinicians
 should follow the athletes instantly during evening training.
