The Relationship of Arm and Wrist Strength to the Velocity of an Open Overhand Volleyball Serve
MetadataShow full item record
Arm and wrist strength and the open overhand volleyball serve velocity were determined for 44 female Ss in 7 randomly selected high schools in District III of the Wisconsin Interscholastic Athletic Association. A cable tensiometer and cinematography~were used to determine the S's strength and serving velocity, respectively. Multiple r was used to analyze the collected data and found the relationship between arm and wrist strength and open overhand volleyball serve velocity was P>.05. It was also found that the reliability r coefficient of the arm strength and wrist strength tests .91 and .90, respectively when comparing the higher to lower strength test score.
