3. The regulations of the changes affect the development of all sports. In Volleyball one of the key changes to the regulations of 1998 was that the pass of serve were allowed to pass with fingers. This resulted to be adopted by several players as a technique to tackle the float mainly serve. Reception Service is part of the syndrome one of Volleyball and important to the success of the offensive action, but for racing performance, while body height of athletes, is important for the racing performance. The purpose of this research is to investigate differences in the effectiveness of the attack syndrome 1 depending on the type of pass in wavy serve with or without jump preceding relative to body height of athletes. The data comes from recording the technical skill of the host wavy serve (N = 8018) of 176 matches teams of the season 2012-13 in A1 National Men category. The data were evaluated by the reception of wavy (dropping a regular 5-level scale), the type of pass used (with fingers or cuff), the result of the attack (on a regular scale of 3 levels) and the height of all athletes groups passing the opposing serve and executed the attack after the reception. The interatomic recording reliability control was tested with Cohen k coefficient and weighted Cohen k. For the statistical treatment of the data (analysis of body height of the passer and the type of pass that chose to greet the service opponent), T TEST, because there was a continuous variable (body height) and a discrete (pass with fingers or cuff ).To investigate the body height and the effectiveness of the attack statistical analysis was by ANOVA, such that there is a continuous variable (body height) and the evaluation of the effectiveness was a regular scale of three levels. The results showed that body height is not a determining factor of success of the attack and that setters prefer to give the ball to the higher receptors

4. In the modern sports body height of players is an important parameter that affects the outcome of the games. This research was done and simple recording of body height receptor and comparing the effectiveness of attacks per body height SUM 7318 LOST 700 AVERAGE 192.9382CM. Standard Deviation 5.37110CM. LOWER HEIGHT 177.00CM. UPPER HEIGHT 207.00CM.

5. RESULTS The statistical results obtained from the analysis of body height and type of host serve opponent that athletes chose not reveal a statistically significant difference.

7. The results of research by applying the T test, the amount of pasers and preference setter to transfer the ball at the highest passer to perform the attack, showed a statistically significant difference in favor of higher receptors. It was observed that the average height of the passer and perform the attack is greater. That is as tall as the paser increases the likelihood to execute himself and attack.

13. DISCUSSION Body height was always guarantee the effectiveness of aggressive actions of teams. This research did not agree with the investigation of Peeri, Sharif & Matinhomaee (2013), which supported the significant statistical relationship (p = 0,05) between body height and the effectiveness of the attack. Statistical significance based on this research analyzes were (p = 0,00).For better draw conclusions about this issue, a larger study which analyzed and the technical elements of offensive players is proposed in relation to body height and the effectiveness of the attack. The overall results of this research was subversive attitudes prevailing in modern Volleyball
