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.
