Time Air Changes of DJ 40-60 Plyometric Test for 12 Weeks Training in Young Volleyball Players in Albania
The study focuses on young volleyball players in Albania during the 12-week plyometric training in order to compare and evaluate the residence time in the air during the vertical jump performance through DJ40-60 test. Methods. Twenty young (male) volleyball players considered as the experimental group No = 10 and control group No. = 10 (age 17 ± 1) are participating in this study. Both volleyball groups were evaluated before and after 12 weeks. Only the experimental group developed 12 week of plyometric training with 2 sessions per week.The control group developed technical and tactical training with the ball. Besides anthropometric measurements they developed drop jump tests by jumping from the cube in height 40 cm and 60 cm Resulsts.The results showed a high correlation coefficient (r = 0,924) and statistically significant (sig.<0.05). Data obtained from two groups GRFP to show that the relationship between the contact time and the time air have also changes between the two tests DJ 40-60cm.Conclusions. The methodology used helps us to compare the high and poor performances that help coaches to program a more detailed plyometric training for the development of jumping skills in young volleyball players. Vertical jumping may be assessed not only by the height of its development but also by the phase of residence in the air.
