Volleyball Research Report

Unpublished study (12/24/2008)

Fourteen (14) NCAA DI volleyball players participated in a study to investigate the
relationship between visual skills and volleyball performance.  Visual skills were
determined by the VizualEdge Performance Trainer® (VEPT), a commercial software
program designed to test and train visual skills.  Individual test scores were determined
for eye alignment, eye flexibility, visual recognition, visual memory, and visual tracking.  
A composite VEPT score was also calculated for each subject. Volleyball performance
was determined by official NCAA statistics.  Research results are as follows:
 
• Houston Baptist University (HBU) is a NCAA DI program that is transitioning to
NCAA DI.  The team finished the 2008 season with a record of 24-7 while
winning the National Transitions Challenge Championship.
• The mean VEPT score for the fourteen subjects was 79.46 with a standard
deviation of 12.56.  The high and low scores were 91.14 and 41.02, respectively.
 
Top VEPT Scores
 
• The top VEPT score (91.14) was achieved by the team setter who ranked first in
assists, second in serve aces, and fourth in digs.
• The second best VEPT score (89.93) was achieved by the team’s top attacker
(outside hitter) who ranked first in attacks and kills, third in serve aces, and
second in digs.
• The third best VEPT score (87.13) was achieved by the team’s top middle blocker
who ranked third in attacks, first in blocks, and third in kills.
 
Top Volleyball Statistical Leaders
 
• The team’s best setter (9.51 assists per set) had the best VEPT score (91.14) on
the team, while the best set percentage (.545) was achieved by fourth highest
VEPT score (86.27) on the team.
• The team’s best attacker (828) had the second highest VEPT score on the team,
while the best attack percentage (.348) was achieved by third highest VEPT score
(87.13) on the team.
• The team’s best blocker (.75 blocks per set) had the third highest VEPT score
(87.13) on the team.
• The player with the team’s best kill per set (3.30) had the second highest VEPT
score on the team, while the best attack percentage (.348) was achieved by the
player with the third highest VEPT score (87.13) on the team.
