Execution Phase

In the execution phase, I still 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 of producing my largest muscles first from the preparation phase and passing it on to my smallest muscles to generate more force. Also, I need to make sure the timing is correct in my sequence. This means that I need to make sure that I'm using the correct timing of my body's segments to produce maximum force. If the timing of my body segments is out of order, the free throw will lack coordinated and the force generated will be less, so I need to make sure that I use my larger muscles first and my smaller muscles first. 

While moving from the preparation phase to the execution phase these joint movements are changing. As you can see from preparation phase I was flexing now in the execution phase my knee is in an extension stance. The knee joint is a hinge joint, the agonist muscle contracting to make this move is the quadriceps and the antagonist muscle relaxing in this movement is the hamstrings. The hip joint is a ball and socket joint, the agonist muscle contacting to make this move is the gluteus maximum and the antagonist muscle relaxing in this movement is the quadriceps. The elbow is also a hinge joint, the agonist muscle contracting to make this move is the triceps and the antagonist muscle relaxing in this movement is the biceps. The differences/similarities I can see in my joints and the ideal are that we are both in a similar position where our joints are extending. 

In the execution phase, I am using Newton's 2nd law. Newton's law states that "acceleration is produced when a force acts on a mass (F=MA)" in my preparation phase I was contracting my lower body muscles and passing it to my upper body muscles in the execution phase to produce force. I can see from my preparation phase that I'm slightly bending my knees, I am still contracting force but not as much if I was to bend my knees more, by bending my knees I am able to contract force in my muscles and the quicker my muscles contracts equals more force in my basketball shot.

In the execution phase, balance and stability are important to produce a well-coordinated shot. Center of gravity can be defined as "the single point at which all parts of an object are equally balanced".  I can see that when I'm going for my shot my centre of gravity is in my body, therefore, I am balanced. Also, I know I am balanced because my line of gravity is going through my centre of gravity and through my legs. The differences/similarities I can see in my joints and the idea being that we both are in the same stance and that we are both slightly bending our knees to hold our base of support.

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. The more segments I'm using the more force I contract by using my larger muscles first will give me force and passing it to my smaller muscles will give me more force. Also, I know I am following the principle of sequencing because I am flexing my lower muscles.

 In the preparation phase, I am contracting my lower body muscles. This means that I am using my hips, knees, and ankle joints at this phase. The knee joint is a hinge joint and it's also flexing, caused by hamstrings and quadriceps, the hamstrings being the agonist's muscle and the quadriceps being the antagonist's muscle. The hip joint is a ball and socket joint, my hip is flexing because I am in a stance and all my joints a flexing, which is caused by the quadriceps being the agonist and the Gluteus maximum being the antagonist. The ankle is a hinge joint/Plane joint, you start with dorsiflexion, which is caused by the tibial Anterior being the agonist and the gastrocnemius being the antagonist.  The differences/similarities I can see in my joints and ideal are kinda the same as the professional one because we are both flexing our knee joints and we are standing in the same stance. 

In this 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 first law states that "an object at rest remains rest until a force is applied to create inertia" to overcome inertia I will need to produce force by using my lower muscles to overcome inertia.

In the preparation phase, balance and stability are important when performing a sporting movement. The line of gravity is the direction of a force of gravity going through the body downwards when the line of gravity is within the base of support you are stable, the base of support refers to the area beneath an object or person which includes every point of contact that the object or person makes with the supporting of the surface I can see that I am balanced because my two feet is on the floor which means I am stabled. My line of gravity is located where my belly button is, therefore I am stable which allows my body to produce enough force in the preparation phase. The differences/similarities I can see in my balance and stability compared to the ideal are kinda the same as the professional one because we are using the same base of support to keep our body stabled.
