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
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
