Functional Anatomy: Non-Dominant Arm Tennis Ball Throw
Functional Anatomy
Functional anatomy – Shoulder
Using my knowledge of Functional Anatomy, I can thoroughly asses my non dominant arm tennis ball throw from my preparation phase to my execution phase of the throw. Just looking at the shoulder of my left arm which is a Ball and Socket synovial joint, which is a joint that allows for a large range of different movements. From the preparation phase to the execution phase, my left shoulder is abducted with slight protraction this is because my arm is away from my midline. This is happening due to my agonist muscle which is my deltoids which are contracting and shortening which are pulling my humorous up and away from the middle line of my body. My antagonist muscles are the Pectoralias major and the Latissimus Dorsi which are relaxing and lengthening allowing the movement to occur in a controlled manner. The bones in the shoulder are the Clavicle, the Scapula, and the Humorous

Using my thorough understanding of functional anatomy I can analyze how my elbow performed during the tennis ball throw with my non dominant arm from the preparation phase to the execution phase.
Looking at my left arms elbow, which is a hinge joint. This only allows for a limited range of motion. During the preparation phase of my throw we can see that my left elbow is fully extended. This is increasing the degree of which my radius is from my humorous. This is occurring because of my agonist muscle the Tricep which is contracting and shortening pulling my Radius and Ulna away from my humorous. My antagonist muscle the Bicep is relaxing and lengthening allowing the extension of my elbow to happen in a controlled manner. The bones which make up the fore arm are the Ulna, and the Radius. My upper arm contains the
Humorous.
Biomechanics
Force Summation
Balance and stability
Projectile motion
Force Summation is to give an object momentum in different sports and activities such as throwing, kicking, or striking a different object. The amount of moment given to an object is due to “the sum of all forces generated by each body part”. To gain the maximum momentum on an object, the force needs to be generated by using as many segments of the body possible, in the correct sequence using large muscles first and the smallest muscles last. This also must be done with the correct timing, as one body part is about to stop moving the next should begin. There should be no pause in between movements. This should all be done through the greatest range of motion. Using force summation in my non dominant arm throw helped improve my throw because I knew how to use my body parts and muscles correctly to gain the maximum distance with my non dominant throw. By focusing on using as many segments of the body, in the correct sequence, with the correct timing, and through the greatest range of motion I could get the maximum distance out of my non dominant throw.
Balance and stability is made up of three principles. CoG (center of gravity), BoS (base of support) and LoG (Line of gravity). The closer your CoG is to your BoS the more stable you are going to be. The wider your BoS and the more points of contact you have the more stable you are going to be. The closer your LoG is to the center of your BoS the more stable you will be. I applied these 3 principles to my throw to gain the maximum distance with my non dominant arm. Making sure that I had good balance and stability was key to my throw success. This is because having a good balance and a stable platform allowed me to correctly use my muscles and body to gain the maximum force summation.
Projectile Motion is an object which is thrown, hit or projected away from the body. This object then becomes a projectile. This projectile is then influenced by 5 different principles, 2 of which we cannot control. 3 of these principles however we can manipulate depending on the task of which we want the projectile to do. The principles we cannot control are Gravity, and Air resistance. The principles we do have control over are the Speed of release, height of release, and angle of release. Different angles of release affect the height of which the projectile is going to travel. When a ball is released from ground level, the optimum angle of release is 45 degrees. The angle of release is important when wanting the projectile to go higher than ground level. If you are looking for optimum distance (like me for my non dominant arm throw) then your angle of release should be at 45 degrees. The height of release is what determines the distance the object will travel. In terms of my non dominant arm throw, having a good height of release which I can incorporate into my throw without affecting my optimum angle of release and my optimum speed of release is essential to gain maximum distance. The speed of release, in terms of my non dominant arm throw, this concerns how much force you put into the throw. In theory, the harder you throw the ball, the further the projectile shall travel.
By implementing the 3 principles of Biomechanics, I could efficiently get the maximum distance out of my non dominant arm throw. My speed of release is determined by how fast I use force summation. My angle of release is affected by my balance and stability. If I have a wider base of support and my line of gravity is in the correct position I can effectively gain the optimum angle of release and height of release to get the maximum distance out of my non dominant arm throw.
Skill Learning
During the learning stage of throwing with my non dominant arm, I was in the cognitive stage of learning. This stage is the first stage of learning, also considered to be the novice stage of skill learning. When I was in the cognitive learning stage I encountered many errors and variable results when throwing with my non dominant arm.
Before beginning to practice throwing with my non dominant arm, I had to analyses and classify the skill. I discovered that the skill is a gross skill which involves many large muscle groups. It is also a discrete skill. This is because the skill involves a distinct start and end point
Throughout the skill learning stage of my non dominant arm throw we used the distributed practice method. This method was effective in the learning stages of my non dominant arm throw because learning to throw can be quite boring and become repetitive. Using distributed practice helped overcome the boringness and repetitively of the activity.
We implemented the distributed practice method by playing games such as angry birds, however, instead of using our dominant arm to throw the object, we used our non dominant arm to help us practice with it and become more familiar with throwing with our non dominant arm. The positive thing about using this method of practice is that i won't get bored of doing the same old method of learning. Having a game to play makes it more entertaining and makes me want to practice using my non dominant arm more often. However there are some downsides to this method. Often using this method can amplify poor techniques which will not improve your non dominant arm throw unless changed. Using the distributed practice method is good for the early stages of learning because playing simple games that gradually introduce the non dominant arm throw allow me to become more comfortable with my non dominant arm.
Using this practice method of distributed practice, my non dominant arm throw became more comfortable and i was able to more correctly throw an object with my non dominant arm.
Inter-relationship
Two examples of specific training session that we did to improve my non dominant arm throw were when we were given class time in groups to create a practice session using our non dominant arm. During this lesson we were able to do drills and play games which were designed to hone our non dominant arm throw skills.
Another example was when we played a mass game of thunder dome but instead of using our dominant arm to throw the ball we had to use our non dominant arm. This made the game more interesting and harder to play while also improving our non dominant arm throwing skills.
