All four components play a part in optimizing power and accuracy. The speed of the run up is transferred into the jump and horizontal force is transferred into vertical force Mann, The elbow, wrist and shoulder are then pull back and the arm is medially in a downward position Mann, ; Alexander et al, In figure 7 we can see the heel contacts the ground before the toes Refer to figure 7.
This blog will be discussing right handed players for indoor volleyball players. In the early phase of the hitting motion of the volleyball serve, the hitting arm is placed in a cocked ready position.
The rotation of the foot allows the server to change the direction of their trunk to the side of the court preparing their arms for the swing Alexander et al, What biomechanical principles are involved in a volleyball serve? The faster the ball or shuttlecock accelerates through the air results in the opposing team having less time to set up for the return.
The jump topspin serve results in the ball travelling at higher speeds in comparison to the jump float which travels slower through the air but changes direction at the last minute.
The float serve has the ball deviate and alter direction mid-flight, making it very difficult for the opponent to successfully read the trajectory, creating an unpredictable component to the game Nathial, As the hand contacts the ball the wrist flexes and due to pronation and wrist adduction the hand rotates forwards Alexander, et al.
The wrist is relaxed to increase the range of motion and increase power Prsalacited in Alexander, et al. Volleyball Steps to Success.
Server stands five metres behind the baseline to allow for a run up. Once again, this allows downward and angular force on the ball. When the foot contacts the ground in a downwards force, the ground exerts an equal and opposite reaction which accelerates us forward due to the transfer of weight Blazevich, As the arms and the trunk accelerate vertically, the servers legs push down proximal on the hip joints, increasing downward force.
Ball velocity was recorded with a Tribar Sport radar gun Jugs Pitching Machine Company, Tualatin, Oregon from a point directly in line with the anticipated trajectory of the volleyball. A greater angular impulse will be needed for a float serve as the technique requires that there is no follow through with the arm.
The server should be aiming for the ball to land inside of the court. Volleyball, Figure British Journal of Sports Medicine, 45 6 Stepping motion The stepping motion of the volleyball serve is a simple, yet important part of the volleyball serve when considering power.
These photographs show the different back swings which can be performed. At the initial stage of the ball toss figure 1. In figure 1 looking only at the feet position you will notice that the sever has their feet almost parallel to each other with the feeding foot slightly forward.
Although there was an insufficient number of participants to statistically analyze the jump serve, the data for it appear similar to those of the cross-body and straight-ahead spikes.The final part of the volleyball serve is the follow through, which its main aspect in the volleyball serve is to provide greater accuracy.
By continuing the range of motion well past the impact of the ball in the direction intended, the balls flight path is. Jun 19, · Biomechanical principles can be transferred into a range of different sports and sporting skills. The principles discussed here all effect sports other than volleyball and can be used accordingly.
First we discussed momentum and using this to build up power for, in this case, a big jump. Transcript of Biomechanics of a Volleyball Serve. Biomechanics of a Top Spin Overhand Volleyball Serve Proper Technique for a Top Spin Overhand Serve Biomechanical Mechanisms involved in overhand serving Impact-Collision and exchange of force during short time interval.
The overhand volleyball serve is a good place to start when learning to play volleyball. Learn to perfect your form with lots and lots of practice. Serve a Volleyball Overhand.

The volleyball arm swing is a lot more complicated than it seems – there is way more to it than meets the eye. First off, a volleyball arm swing is a rotation of the body.
The term is “ipsilateral rotation”, rotation of one side over a fixed point. The best way in which to describe the biomechanical principles of the volleyball serve is through three different phases; preparation, contact and follow through.
Each phase is an important part of the serve as it helps to form the kinetic chain (Blazevich, ).Download
