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.
