Execution Phase

In the execution phase I stil need to contract as many segments as possible to generate maximum force. As well as using my lower body segments, I also need to contract my upper body muscles in my Basketball Shot. In order to generate maximum force I need to follow a sequence also still using as many segments as possible to create maximum force. I can see that I am following the principle of sequencing because i am starting my force off from my lower body muscles all the way upwards through to muscle upper body muscles. Also, I need to make sure the timing is correct in my sequence. This means that I need to make sure i am executing my body segments in the correct way.

While moving from the preparation phase to the execution phase these joint movements are changing. The Knee joint is a hinge joint. The agonist muscle contracting to make this movement is quadriceps and the antagonist muscle relaxing in this movement is my hamstring. The Hip joint is ball and socket joint. The agonist muscle contracting to make this movement is gluteus maximums and the antagonist muscle relaxing in this movement is quadriceps. The Elbow joint is hinge joint.The agonist muscle contracting to make this movement is triceps and the antagonist muscle relaxing in this movement is biceps. The differences/similarities I can see in my joints and the ideal athletes legs and his lower body muscles are bent a bit more than mine. A similarity that i notice between me and the athletes body is I released the ball by my shoulder and he made his shot over his head.

In the execution phase I am using Newton's 2nd law. Newton's second law states when a force is applied to an object, it will move in the direction of the force being applied . To create greater force i flexed my knees, then my legs muscles are then bent allowing my calves to perform flexion and my quadriceps to extend. So the more i flexed my knees whilst using my hips it created a greater force allowing me to have a stronger shot that goes further.

In the execution phase balance and stability is important to produce a well coordinated shot. To be balanced my center of gravity has to be within the inside of my body. Center of gravity is defined as the point at which all points are equally balanced. Also I know I am balanced because i have to feet still in touch with ground. The similarities I can see in my joints and the ideal is both of our legs are planted to the ground before going for the shoot. 

Preparation Phase

To generate maximum force I need to contract as many segments as possible. I know I am contracting segments in my preparation phase because my lower body muscles are working. Also I know I am following the principle of sequencing because when i bent my knees i'm contracting my bigger muscles first then up to my smaller muscles like my arms to shoot the basketball.

In the preparation phase I am contracting my lower body muscles. This means that I am using my Hips, Knees and Ankle joints in this phase. The agonist muscle contracting to make my hip flex is the quadricep and the antagonist muscle relaxing in this movement is the gluteus maximus. My ankles are in the position of dorsiflexion, the agonist muscle is my tibialis anterior and the antagonist muscle is my gastrocnemius, which is helping me to make a coordinated shot. In the preparation phase the similarities I can see in my joints and the ideal athlete is how we are both solidly stable.

In the preparation phase I am using Newton's Laws. The Newton's law that I am using in this phase is his 1st Law. Newton's 1st Law states a body continues in its state of rest or uniform motion unless an unbalanced force acts upon it. To overcome greater inertia i am applying more force to movements and i am doing that by contracting my leg muscles and i get into a position that allows me to do so. My knees and lower body muscles are helping me to create that force. When i applied force i also noticed that as i applied that force it was going in a certain direction.

In the preparation phase balance and stability is important when performing a sporting movement. Line of gravity is defined as the line that passes through the center of gravity to the ground. Base of support is defined as the area that is in contact with the ground. The larger the contact with the ground, the greater the stability. My line gravity is located from my my belly button and going downwards through to the ground, therefore i am stable. So also i can see that i have a solid base of support because i am planted with two feet on the ground. The differences/similarities I can see in my balance and stability compared to the ideal are very similar. The only difference i notice is my knees being more bent then the ideal athlete.
