Movement Analysis on the Overhand Serve

Hello.

My name is Shake Phoebe and I'm going to

be doing my movement analysis on the overhand serve.

So to begin the overhand serve is a type of service

performed in volleyball to begin a match and

there are three different types of overhand serves.

We have the top spin serve

the jump serve

and we have the floater serve.

The floater serve is what we're going to be analyzing today.

So to begin a floater serve,

it's really important that we have the correct footwork.

The correct footwork involves your right foot

being slightly placed in front of your

left foot and this should be about 12 inches of distance between the two ft

and your left knee should also be slightly bent.

Just the scene in the picture right next to me,

moving onto your arms, starting with your right arm,

your upper right arm should be parallel to the floor and the frontal plane of

the body and your hand should be close to the head near the ear,

around that area in a claw like manner.

Just the scene in the photo right there

and then your left arm is going to be the arm that tosses the ball up

so your left arm is going to toss the ball in front of the right arm

and the right shoulder and it's going to be tossed in a position just above the

level of the head and slightly in front of the frontal plane of the body,

putting everything together after your left arm tosses the ball,

you step under the toss with your left foot

and strike the ball underneath.

The ball should be strike towards the top of the back in a down and outward motion.

And the arm should also follow all the way through.

And you should end with a wrist snap.

Now talking about all the joints involved in a overhand sir we're gonna start

with the tailor coral joint which is also known as the ankle joint.

That is a hinge synovial joint and it's composed of the talus,

the tibia and the fibula bone.

We also have the knee joint that's going to

be a by condor synovial joint and it connects the

fibula the fever,

the tibia and the patella And all those bones make up make

up the tibia for moral joint and the patella femoral joint.

We also have the hip joint that is going to be a ball and socket joint

and it articulates the head of the femur and the stable um of the pelvis.

Moving on.

We have the shoulder joint that's also a ball

and socket joint and it's composed of the chromeos.

Navicular joint and the glen or humor joint.

We have the radio carpal joint which is going to be

your wrist joint that's going to be a consulate synovial joint.

It's going to articulate the forearm and your hand

and last but not least we have the owner.

Oh no Hugh moral joint that's gonna be known as your elbow joint.

So it's gonna be a synovial hinge joint and it's

going to articulate the distal humerus and the proximal ulna.

Now we're gonna talk about the muscles involved in an overhand serve,

starting off with the agonist muscles.

So we have the biceps the triceps posterior deltoid,

the sub scapular varies and the separatists anterior.

So those are the agonist muscles involved in an overhand

serve and the antagonist muscles are going to be the

thomas Dorsey, the abdominals, the petrels major and the terrace major.

A overhand service considered an eccentric muscle contraction.

And there's also 90° range of motion

and that's involved in the Triceps and the pet manner.

So moving on an injury that could inhibit a player

from performing an overhand served is a jammed finger.

A jammed finger is injury to the P. I. P.

Joint and a player can't perform an overhand

serve because there's so much pain and swelling

right here that there isn't there isn't gonna

be much contact with the ball and the fingers

and an assist device or just treatment to

help the healing process of a jammed finger.

Is a finger splint as seen in the photo next to

me and players are able to play with the finger splint.

It isn't advise that they do maybe for a couple of days.

But it is personal preference because there is an alternate way of serving which is a

underhand serve.

An underhand serve involves the player serving with their hands in a fist and

hitting the ball with the heel and the flat surface of their fist.

So because there isn't much contact with their fingers and the ball,

there isn't gonna be any pain and there's not gonna be

any hindering to the healing process of the jammed finger.

That is my presentation today, and thank you guys for listening.
