The statement of this study was comparison of selected physiological variables among men volleyball players of different positional play. The study was designed to compare the physiological variables of men volleyball players of different positional play. To achieve the purpose of the study, sixty men volleyball players were selected from Annamalai University, Chidambaram, Tamil Nadu at random and their age ranged between 18 and 25 years, who has participated at minimum, inter college. Based on the relevant literature reviewed and in accordance with views of professional experts in Physical Education, the after reviewing the related literature and books the investigator selected the variables namely. Body Composition, Mean Arterial Blood pressure, Resting Pulse Rate. The selected criterion variables were measured from the college men volleyball players. One way analysis of variance (ANOVA) was used to find out the Comparison between independent and criterion variables. In all the cases, 0.05 level of confidence was fixed to test the significance, which was considered as appropriate. On the basis of statistical findings, the following conclusions were drawn:-
1. There is no significant difference among setter, attacker and blocker in their body composition.
2. There is significant difference among setter, attacker and blocker in their mean arterial blood pressure, resting pulse rate.
3. The setter and attacker differ significantly in their mean arterial blood pressure and rest of the groups does not differ significantly.
4. The setter, attacker and blocker differ significantly in their resting pulse rate. 5. The setter and attacker differ significantly in their resting pulse rate and rest of the groups does not differ significantly.
