Introduction In most sports played by athletes today, ball velocity and velocity of the human anatomy both have an exceptionally high correlation with the effectiveness in that sport. Athletes who can perform at a fairly high velocity, or that can put objects in high velocity, tend to excel in their sport, especially power sports. Due to the importance of velocity in most power sports, the student researchers found it intriguing to learn more about how peak velocity of a ball can be generated. In this study, the student researchers will examine the different factors affecting the velocity of a volleyball spike by breaking down the major actions of a full approach and swing of a volleyball hit. The Student researchers will find both linear and angular velocity of the hand, vertical and horizontal displacement, and BMI through precise measurements and extensive testing found through computer software. Vertical displacement will be measured through a simple vertical jump test. Horizontal displacement will be measured through a broad jump test and also through the actual movement of the volleyball hit. The vertical and broad jumps are direct measurements of an athlete’s hip and lower body power and explosiveness. Subject BMI and limb measurements were also taken into consideration for testing the individual differences. The student researchers will explore the subject’s gross anatomy to see if it alone has effects on ball velocity. The student researchers assume that greater lower body power and explosiveness along with lower BMI and longer limb measurements will have a significant influence on increased velocity of a volleyball spike.
