Shooting a basketball Describe in detail the joints being utilized in the motion, the bones that comprise each of those joints, what joint action is taking place, and the muscles that are generating the motions and what plane of motion and axis of rotation is being utilized for each motion as the person goes through the throw. Make sure to descrbe in detail the motion of his right arm (elbow and wrist/hand) from 1 to 6 a. + 100%Explanation / Answer
Muscle Contraction
There are two different types of contraction. When muscular effort marks in a movement, as it often does in basketball, it is called an isotonic muscular contraction.
There are two types of isotonic contractions:
When a muscle contracts but there is no movement, the result is an isometric contraction.
In basketball, most movements are isotonic contractions.
Free Throw
However a free throw potency not seem similar an action that involves a lot of movement, multiple muscle groups work in performance in isotonic contractions, as each muscle group involved works to result in movement. A free throw engages knee, hip, ankle and elbow extensors as well as shoulder and wrist flexors
Dribble
Impartial like a free throw, dribbling engages multiple muscle groups across your body. When you dribble the ball, the muscles in your shoulder, elbow and wrist are particularly responsible for the pumping motion that pushes the ball to the ground. Your deltoids, triceps, biceps and forearm muscles must lengthen and shorten to correctly and efficiently dribble the ball
Chest Pass
The chest pass, which resembles a push up motion, is a common way to get the ball to another player. The elbow extensors, including the triceps, pectoral and deltoid muscles, work in concert as an isotonic contraction to enable you to make a chest pass to another player.
Shooting a Basket
It may sound surprising that shooting a basketball takes more than arm movement. The most important muscle group to engage when shooting a basketball is the core, which principally includes the abdominis muscles; because there is no movement involved in simply engaging and having a strong core, the contraction is isometric. In addition, both wrist flexor and extensor muscles in your forearms create an isotonic contraction as the ball is thrown up toward the basket through the motion of bending your wrist.
Running and Jumping
The basketball wouldn't move down the court if it weren't for athletes running and jumping. To attain these movements, the quadriceps, hamstrings, calves and gluteus maximus work together to create isotonic contractions that propel the legs forward; when jumping vertically, the ankles also engage in isotonic contractions to achieve higher lift off the ground than running typically does.
Muscle in elbow to wrist
Triceps
Shoulders
Forearm Muscles
Biceps
The triceps are the large muscles located on the backs of your upper arms. Their anatomical function is to extend the elbow. This action would be seen when your arm goes from a bent to straight position during your shot
Every time your upper arm gets elevated, your shoulder muscles are being used. While shooting a basketball, the shoulder muscles on your shooting arm are being more heavily recruited than the muscles on your non-shooting arm. This is because the humerus--the large bone in your upper arm--is being elevated higher. The trapezius and deltoids are the anatomical names for the muscles being used. The trapezius is located on the top of the collar bone, and the deltoids are found at the very top of the arm around the shoulder joint
The forearms contain two groupings of muscles on the inner and back sides. The wrist extensors open the fingers and cause the hand to go back toward your upper arm. These muscles are being activated when you ave the ball up in front of your body. Once you follow through with your shot and your hand goes downward, your wrist flexors are being used.
The biceps brachii are the muscles on the front of your upper arms. They cause the elbow to flex, which is a motion you would see when your lower arm is coming back toward your upper arm. When shooting a basketball, your biceps promote the movement of the ball from a position in front of your body to the shooting position. Notice how both elbows are bent right before you shoot

A free throw engages knee, hip, ankle and elbow extensors as well as shoulder and wrist flexors
