Environment, Individual, Task: Basketball Free Throw - Coggle Diagram

- - - - Known to subject before hand as they switch ball sizes for each trial
- - - - Maintenance of Balance Throughout Shooting Motion
        
        Via Vestibulospinal Reflexes
    - - Saccules
        
        Detects Linear Head Acceleration in the Vertical Plane
        
        Head Movement During the Up/Down Phase of Shot; Knees Bent to Standing Knee Extension Upon Release
    - - Head Motion Signaling to CNS Via Vestibular Transduction from Otolithic Membrane
  - - - Central Vision
        
        Basketball Hoop, 15ft Away from Free Throw Line
      - Peripheral Vision
        
        Surroundings of the Gym + Ball In Hands Throughout Shooting Motion
      - Binocular Retinal Disparity
        
        Depth Perception of Basketball Hoop/Hoop Location
    - - Ventral Stream
        
        Object-Centered Frame of Reference
        
        The Hoop is 15ft Away from the Ball At Time of Release
      - Dorsal Stream
        
        Body-Based Frame of Reference
  - - - Primary Movement: Elbow Extension So Spindle Activity is Located in the Antagonist Biceps Muscle
        
        Dynamic Change in Biceps Length
        
        Sensed By Group 1a Afferents
        
        Wrapped Around Intrafusal Muscle Fiber Dynamic Bag 1's
        
        Bicep Stretch (Lengthening) During Extension Signaled by Increased Discharge Rate of the G1a Afferents
        
        G1a Action potentials sent to brain via spinocereballar tract for unconscious processing
        
        Static Change in Biceps Length
        
        Group 2 Afferents
        
        Wrapped Around Static Bag2 and Chain Fibers
        
        Senses Instantaneous Stretch of Biceps
        
        G2 Afferents Discharge Rate Increased with Increased Static Biceps Length
        
        Gamma Motor Neurons
        
        Alpha Gamma Co-Activation
        
        Seen In Triceps During Extension
        
        Shortening of Triceps Muscle During Shooting Motion
    - - sensed by group 1b afferents
        
        sensitive to force changes in muscle due to different ball size
    - - knee
        
        sense angle, direction, & velocity when bending & extending during shot
      - elbow
- - - - Free Throw Shooting Goal Directed Limb Movement
        
        Rubrospinal Tract
        
        Excitatory Influence on Proximal Upper Limb Flexors for Shooting
    - - Reticulospinal Pathway
        
        Maintenance of Posture Throughout Shooting Motion Via Excitatory Influence on Extensor Muscles
  - - - Responsible For Controlling Arms And Communication For Interlimb Coordination For Shooting Motion
    - - Aid In Standing Upright and Breathing To Maintain Balance and Posture
    - - Controlling Legs To Aid In Balance To Stabilize Shooting Motion
  - - - Receives Input from Movement Generating Brain Centers
        
        Receives Efference Copy of Free Throw Shooting Motor Command from Primary Motor Cortex
        
        Receives Posterior Parietal Cortex Free Throw Shooting Motor Plan
    - - Receives Copy Of Sensory Feedback From Somatosensory Receptors After Each Free Throw Shot
  - - - Sends free throw motor command to the alpha motor neurons in the spinal cord
        
        Results in the execution of the free throw shooting movement
    - - The planning of the free throw shooting movement pattern
    - - Free throw shooting movement sequence selection derived from memory/internal cues
    - - Involved in movement selection to external cues, with making or missing a basket being the externally driven cue
- - - - Prevent falling due to shift in COM
        
        Lifting arms to shoot
        
        Torso & legs
        
        shift forward due to force from basketball pushing back
        
        prevents COM going outside BOS
        
        slightly shift to left prior to right arm lift
  - - - shooting while both feet are planted on solid gym floor
