Abstract

Subjects were 26 male football players aged 16±1 y, height 171±7 cm, body mass 64±8 kg, and training age of 6±4 y. The study examined changes in linear and angular sprint performance and the effect of angular factors on sprint speed and anaerobic power. 30 m sprint performance was determined by recording the time in every 10 m, and then the 30 m distance has been measured by 10 m 90 degrees turns, and finally the 30 m distance has been measured by 10 m 180 degrees turns and the sprint values have been determined and the relationships between the three measurements have been examined. While smooth linear acceleration was detected only in 30 m sprint runs (P<0.01),the most loss of speed was detected in the second 10 m of 90 degrees turns (P<0.05) and in the last 10 m in 180 degrees turns (P<0.01). The average 30 m sprint time were increased by 46% compared to 90 degrees average turn time (P<0.01), and were increased by 97% compared to 180 degrees average turn time (P<0.05). When the 90 degrees average turn value and the 180 degrees average turn value were compared, the average value of the increase in the turn angle was increased by 36% (P<0.05). When the 30 m sprint, 90 degrees turn and the 180 degrees turn values of the experimental subjects were examined as anaerobic power, it has been found out that when 30-meter sprint watt value is compared with 90 degrees turn watt value, a % 310,5 of negative effect from the reference value has been determined, whereas the 30 meter sprint watt value has been affected % 775 negatively from the reference value of the anaerobic power when it is compared with 180 degrees turn watt value (P<0.001). When the 90 degrees turn watt value is compared with the 180 degrees turn watt value, it has been found out that the difference in the angle of the turn has affected the average watt value (Anaerobic power) % 250 negatively (P<0.01).
