This lab will analyze two different motions, the lateral pass in rugby and the spike in volleyball (rugby: http://www.youtube.com/watch?v=cOy3MiVOzJs Volleyball: http://www.youtube.com/watch?v=h pFWZrXuC98). The lateral pass is a motion in which a participant is holding the rugby ball with two hands. They swing both of their arms in the direction that they want to project the ball and add a push to the ball with the distal arm. They then use the inside arm to help guide the ball in the direction of the player that they are passing to. The volleyball spike is a movement where a person jumps as high as they can vertically. They use their lead hand to smash the ball, while gaining as much velocity as possible to have a high speed of the ball to…show more content… 1a. Volleyball is a closed skill because the performer is in a predictable environment and is able to preform the sequential motions of the skill.
b. In volleyball the overall performance objective is projection, accuracy, and performance at high velocity.
2a. In volleyball the wheel axle motion occurs within the shoulder during rotation and in the wrist when in contact with the ball. Lever action occurs within the shoulder. In this scenario the load is the ball, effort is the shoulder muscles, and the fulcrum is the shoulder joint.
b.1. Ipsilateral and contralateral shoulder extension
1. Extension of the torso
2. Ispilateral shoulder flexion 200 degrees
3. Contralateral shoulder flexion 180…show more content… Ipsilateral and contralateral shoulder rotation
3. Ipsilateral and contralateral arm movement to the right
4. Wrist flexion of ipsilateral hand and extension of ipsilateral hand, ball is released
c. In the lateral pass both hands follow a rectilinear path.
d. Lateral pass is an open kinetic chain. This is because the end of the kinetic chain is able to move freely without any restraints. This helps in achieving the OPO because the player is able to direct the ball properly and accurately without boundaries to the pass.
e. During a rugby pass multiple factors contribute to the OPO: the player lowers their center of gravity by flexing their torso and bending their legs (this gives them greater stability when throwing the ball), the player co-ordinates all the motions and body parts when preforming the motion and by traveling in a rectilinear motion. All of these contribute to achievement of proper projection of the ball and an increased accuracy of the pass enabling a proper lateral pass.
Many components contribute the volleyball spike and the lateral pass in rugby. All work together in allowing the performer to achieve the overall performance objective of projecting the ball with speed and accuracy or passing in rugby with control and
