Selection and classification of high school volleyball players from performance tests

Area of Science:

• Sports Science
• Motor Performance Analysis
• Volleyball Biomechanics

Background:

• Accurate player identification is crucial for team development in high school volleyball.
• Differentiating player skill levels (freshmen, junior varsity, varsity) and starter status requires reliable assessment methods.

Purpose of the Study:

• To evaluate the accuracy of general and specific motor performance tests in classifying high school volleyball players.
• To determine the precision of these tests in distinguishing between starters and non-starters across different team levels.

Main Methods:

• Fifty high school volleyball players underwent six general and four specific motor performance tests.
• Tests included anthropometric measures (height, weight, body fat), agility, vertical jump, flexibility, and sport-specific skills (volley, pass, spike, bump/set).

Main Results:

• Varsity players demonstrated superior performance in vertical jump, agility, and specific ball-handling skills compared to freshmen and junior varsity players.
• A combination of forearm pass, overhead volley, vertical jump, and weight correctly classified 68% of players by team level.
• Forearm pass, height, weight, and shoulder flexibility correctly classified 78% of starters versus non-starters.

Conclusions:

• Both general and specific motor performance tests are effective tools for selecting and classifying high school volleyball players.
• These assessments provide valuable data for talent identification and team composition in volleyball programs.
