The aim of this study is to determine the effect of regularly applied volleyball training on the physical fitness values of High School students. A total of 62 students from three different high schools participated in the study. The students who participated in the study were divided into two different groups; one group consisted of those who did not join in any sporting activities except for the physical education classes at school while the other group consisted of those who played in the school volleyball team in addition to the physical education classes at school. Eight tests were used derived from the EUROFIT test: flamingo, plate tapping, sit and reach, standing broad jump, handgrip, sit-ups, bent arm hang and 10 x 5m shuttle-run tests to determine the physical fitness of the students. The data obtained were interpreted using the SPSS 14.0 packet program.
