Purpose. Training programs for volleyball players can benefit their physical and physiological development (R. Lidor et al, 2010). Therefore, the purpose of this study was to determine the effects of 4 month volleyball training on flexibility, jump, speed, and agility in preadolescent girls. Methods. Twenty girls (xage: 10.5±1.5, xsports age: 1.1±0.4) volunteered to participated in this study. The informed consent was taken from all parents. Pre-test, mid-test (on the 2nd month) and post-test (on the 4th month) measurements were taken. The body height and weight, flexibility (sit and reach test), speed (20 m run test), vertical jump (with arm swing allowed), standing long jump, agility (Illinois agility run test) were measured. Results. 4 month volleyball training significantly affected subjects’ body height, body weight, flexibility, jump, speed, and agility performance (p<0.05). The jump, speed and agility performance were significantly improved, although flexibility decreased for this period. Conclusions. Our results were parallel to the previous studies (R. M. Malina, 1994, D. R. Melrose et al., 2007). Subjects’ body height and body weight was increased, this results could be related the physical development. In the further study, these performance tests would also be applied on the control group at the same age, to test whether this positive improvement arose from the volleyball training.
