Abstract:

Background: This study aims to employ Discriminant Analysis to examine the differentiation between state-level volleyball players categorized as "High Performance" and "Low Performance,". 
Objectives of the Study: 
1.    To characterize the level of anthropometric, functional and volleyball skill of volleyball players on the basis of high and low performance.
2.    To develop discriminate model for classifying a State level Volleyball Players into High or low – performance categories.
Materials and methods: In this study 72 male state-level volleyball players from various volleyball academies were selected, their age ranging between 19-25 year, all were selected by using purposive sampling. These selected subjects had been alienated into two group i.e. high and low performance group. Anthropometrical variables were measured by anthropometric kit, General volley pass playing ability, serving skill, passing skill and AAHPER serving test Numerical was measured by Brady’s wall volleying test, AAHPER passing test, AAHPER set up test and AAHPER serving test respectively. Leg Explosive Power, Shoulder Strength, Agility, Abdominal strength measured Standing broad Jump, Medicine ball throw Distance, 10x4 shuttle run, Sit-ups respectively.
Results: Box’s M test value is 1.357 is not significant it means that the assumption of homogeneity of variance/covariance matrices is not violated. Canonical correlations of function 1 is.639 indicates 40.83% (=.639) of the variation in the two different group. Wilks' Lambda value is.807 which indicates the model is good as only 65.12% in function 1 variability is not explained by the model. The value of chi-square is 15.294 shows the significance of Wilks Lambda. Group means for high and low group means are.482 and -.482 which are group centroid. (78.4%) cases were correctly classified by the model which is quite high, therefore the model can be considered as valid.
Conclusions: Discriminant function for the State level volleyball players on the basis of the performance (High and Low) is Z= -5.331 +.401× (Set Up).
