Transcript of Biomechanical Presentation

The Biomechanical Breakdown of a Jump Shot Stage 1: Preliminary movements Stage 3: Force-producing movements Stage 4: Critical Instant/Impact/ Release Stage 5: Follow-through By Be, Corrina, Emily and Jessica Joint movements: joint movements: joint movements: joint movements: joint movements: Stage 2: Back-swing movements Major Muscles used Newton's Laws levers TYPES OF MOTION Biomechanical Principals Levers Newtons Laws Muscles Types of Motion Biomechanical Principles: MUSCLES LEVERS Types of Motion: Biomechanical Principals Newton's Laws Levers Major Muscles Newton's Laws Types of Motion Biomechanical Principles Newton's Laws Levers Muscles Types of Motion Biomechanical Principals Stability
Summation of joint forces
Continuity of joint forces - All of them -Stability
-summation of joint forces
-continuity of joint forces
-impulse
-direction of force application
-production of rotational motion -joint forces
-continuity of joint forces
-impulse -stability
-summation of joint foces
-continuity of joint forces Knees bent
Elbows in
Feet shoulder width apart
Balance
Feet face towards the basket
Non-shooting hand is up for support Bring the ball towards chest with shooting hand
Bend knees further down
Extend wrist of shooting hand
Non-shooting hand moves up for support Extend legs
Shoulder flexion
Plantar flexion -elbow extension -Wrist flexion adds backspin
-Knee flexion
-Bring non-shooting hand up 3rd class- Axis is at the end with force in the middle Second and Third Class 1st law: -the ball will travel in a forward direction until it reaches the net where it will change direction but stay moving.
-The force is applied by the athlete completing the five principals 1st law: -the ball will travel in a forward direction until it reaches the net where it will change direction but stay moving.
-The force is applied by the athlete completing the five principals 2nd law: The ball used is a standard weight, so the amount of force generated by the athlete will determine the acceleration of the ball 2nd law: The ball used is a standard weight, so the amount of force generated by the athlete will determine the acceleration of the ball 1st law, INERTIA: An object will remain in its state of motion (moving or at rest) until it is acted upon by an external force sufficiently large to disturb that state. -3rd law
-Choose basketball shoes to maximize friction
-Friction between hands and basketball 3rd law 3rd law 3rd law 3rd law, ACTION/REACTION: When one body exerts a force on a second, there is n equal and opposite force exerted by the second body on the first thanks for
watching :) -quadriceps
-gastrocnemius
-gluteal group
-hamstrings
-abdominals Gliding: Feet
Hinge joint: Elbow
Pivot: Head -quadriceps
-hamstrings
-gluteals
-abdominals
-biceps
-flexors Gliding joints: feet
Hinge joints: phalanges
Pivot: head
Ellipsoid: flexion of wrist Ball and socket: Hips -Legs: quads, hamstrings, gastrocnemius, glutes
Arms: Biceps, extensors
Abdominals -Leg muscles as previous stages
-arm extensors to hold weight of ball
-biceps Hinge: elbow Gliding joints: Ankle
Hinge joint: knee, elbow
Ball and socket: hips and shoulders -Legs: quadriceps gastrocnemius, glutes
-Abdominals
-Arm extensors Ellipsoid joints: wrist
Hinge joints: knee Newton's 3rd law applies here as well. Action/reaction 2nd and 3rd class 1st and 3rd class levers Second and Third class levers
