The aim of this study is to evaluate sprinting ability, density of acceleration, and speed dribbling ability of professional soccer players with respect to their positions.A total of 243 professional soccer players were examined. These soccer players are playing in different leagues of Turkey. The F-MARC test battery, which was designed by FIFA, was used(More)
A recently introduced S-box evaluation criteria called undisturbed bits allow the attacker to construct longer truncated, impossible or improbable differentials. In this paper, we analyze the security of Serpent against impossible and improbable differential cryptanalysis for the first time and provide a 7-round improbable differential attack by using(More)
The purpose of this study was to determine the effect of circuit training directed toward motion and action velocity over the sprint-agility and anaerobic endurance. A total of 32 healthy male physical education students with a mean age of 23.92 +/- 1.51 years were randomly allocated into a circuit training group (CTG; n = 16) and control group (CG; n =(More)
The purpose of this study was to examine the heart rate recovery depending on anaerobic running. A total of 23 professional soccer players who were player of Turkish Super Leagues, were examined. Anaerobic Run test was applied to the soccer players and their heart rates were recorded before running, just after running, in 3rd and 6th minutes of recovery(More)
The aim of this study was to examine the effects of an 8-week speed training program on the acceleration ability and maximum speed at 11 years athletes. A total of 30 healthy female athletes volunteered to participate in this study. They were divided randomly into 1 of 2 groups: Experimental group (EG; N = 15) and control group (CG; N = 15). The mean (SD)(More)
