Shooting a basketball By Jack Williamson

While stationary Biceps Brachii: Slightly tensed Elbow joint – Humorous/radious and ulnar: Elbow slightly flexed Shoulder joint – Humerous/Scapula: Shoulder slightly flexed Laticimus dorce: Slightly tensed Hip joint – Femur/Pelvis: Hip: Slightly flexed Triceps: Slightly tensed Hamstring: Slightly tensed Quadriceps: Slightly tensed Knee joint – Femur/patela/tibia: Knee slightly flexed Gastrocnemious/ Solious: Relaxed Tibialis anterior: Slightly tensed

Going up Triceps: Agonist Bicep Brachii: Antagonist Litisimus Dorce: Elbow joint – Humorous/radious and ulna: Elbow extension Hip joint – Femur/pelvis: Hip extension Quadriceps: Agonist Hamstring: Antagonist Gastocnemious/Solious: Agonist Tibialus Anterior: Antagonist Knee joint – Femur/patela/Tibia: Knee extension

After shot Elbow joint – Humerous/radius and unla: Elbow extension Biceps Bracii: Antagonist Triceps: Agonist Hip Joint – Femur/patela/tibia: Hip extension Shoulder joint – Humorous/scapula: Shoulder abduction Quadriceps: Agonist Hamstrings: Antagonist Gastrocnemious/solious: Agonist Knee joint – Femur/patela/tibia: Knee extension Tibialus anterior: Antagonist

Shooting Motion Up phase When in the motion of shooting the basketball certain muscles need to tense and pull hard and others need to relax to get maximum distance on a shot. When your arms extend when shooting your Triceps tense in order for your arm to extend and force the ball forward, but your biceps have to relax for your arms to fully extend. This makes the triceps the agonist as they are the working muscle and the Biceps the antagonist because they are the relaxing muscle. The biceps have to relax for the movement to occur otherwise the arm would stay in a flexed position and no movement would occur. When your Triceps tense it causes your elbow to extend to force the ball forward. Other muscles that help when shooting a basketball are your deltoids and muscles in your forearm. Before you shoot the ball is sitting in your palm, this is called super nation, then after the motion of shooting the basketball you flick your wrist to get maximum power and good form then your wrist goes to pro nation. Other muscles that need to work are your quadriceps, hamstrings, gastrocnemious and soloious, and your tibialus anterior. These muscles also need to work in a certain order and do certain things in order for movement to occur. Your quadriceps are the agonist when extending your legs at the knee and your hamstrings are the antagonist, if the hamstrings do not relax when moving upward then your knees would stay flexed and no movement would occur. When going up your gastrocnimous and solious are the agonists as they are the working muscle and the tibialus anterior are the antagonist. Once again the tibialus anterior has to relax for you to jump higher when you shoot. Your feet would stay in a Doris flexed position if your tibialus anterior does not relax rather than moving your foot into a plantar flexed position in order to get maximum jump when shooting. All of these muscles need to work in a certain order for shooting a basketball to occur, if your muscles don’t work in the required order to shoot a basketball then you could not shoot it properly or very well.

Hip Joint Knee Joint Elbow joint The hip extends as you are going up on the shot, muscles that need to tense and relax when your hips are extending are your glutinous maximums and your hip flexor. Your glutinous maximums is the agonist as it tense when jumping up and your hip flexor is the antagonist because it has to relax in order for your hip to extend. Knee Joint The knee extends as you shoot so you can jump, muscles that need to tense and relax in your legs when jumping for your knees to extend are your quadriceps and your hamstrings. Your quadriceps are the agonist and your hamstrings are the antagonist, if the hamstrings do not relax when jumping then your knees would not extend and would stay in a flexed position. Your quadriceps need to tense fast and hard for maximum vertical jump. Elbow joint The elbow extends when you shoot the basketball, your Triceps need to tense and the biceps need to relax as you shoot. Your Triceps are the working muscle as they are the agonist and the bicep is the relaxing muscle so it is called the antagonist. They Triceps need to tense the same time the Biceps is relaxed in order for movement at the elbow to occur
