Investigation of the Effect of Fatigue on Service Shots' Hit Ratio for Volleyball Players

Abstract

This study was done on the under armour elite volleyball players, with an age range of 18-25, in order to examine whether the players' fatigue status during the match can cause any deflection on the service shots that hit and miss the target towards left and right. The right hand dominant 30 elite volleyball players with mean age of 20.70 ± 1.68 years, mean height 181.93 ± 5.40 cm and with a mean of 74.03 ± 6 97 kg body weight had participated to this study voluntarily. The participated players made 10 service shots to the target after a 20-minute warm-up and 3 sets and then the measurements were taken. The first set of measurements taken after warm-up and the final measurements taken after 3 sets were compared, SPSS program was used to compare the difference between the measurements. As a result of the study it was determined that the services that hit the target, glided to the right and to went to the out decreased numerically but they were statistically no meaningful, but the services glided to the left increased statistically (p<0,05). In conclusion, it was considered that the service shots' deviation to the left has been associated with fatigue and laterality. © 2013 IDOSI Publications.
