    Preparatory Phase of Throwing

    The preparatory phase of throwing involves positioning the body in a way that allows for optimal throwing motion. It involves setting up the body for efficient energy transfer and preparing for the upcoming movement.

    Main Phase of Throwing

    The main phase of throwing involves executing the actual throw, generating power and controlling movement. This encompasses all the coordinated actions of the body leading to the release of the object.

    Final Phase of Throwing

    The final phase of throwing involves the body's movements following the release of the object. This is the result of the remaining energy generated from the previous phases.

    Arm Acceleration in Baseball

    The arm acceleration phase in baseball involves a combination of trunk bending, wind-up, and shoulder movement. The body twists and rotates to generate force for the throw.

    Wind-up Phase in Baseball

    The wind-up phase in baseball involves bringing the pitching arm back and preparing for the throw. This includes adduction and internal rotation of the shoulder, as well as the opposite knee coming up towards the chest.

    Arm Deceleration in Baseball

    The arm deceleration phase in baseball involves slowing down the arm after release to prevent injury. This is achieved through eccentric contraction of the rotator cuff muscles.

    Stride Phase in Baseball

    The stride phase in baseball involves taking a step, extending the opposite leg and creating momentum for the throw. This contributes to the overall power generation.

    Arm Cooking Phase in Baseball

    The arm cooking phase in baseball involves bending the trunk forward, adducting and internally rotating the shoulder, and extending the elbow. This prepares the arm for the final throw.

    Basketball Shot Preparation

    The initial setup for a basketball shot involves the dominant foot positioned forward, hands holding the ball, and gathering visual information before the action begins.

    Shooting Phase

    This phase of the basketball shot involves extending the knee, elbow, and releasing the ball. The wrist also flexes at the moment of release.

    Flight Phase

    This part of the basketball shot follows the release of the ball, with body parts returning to their normal positions due to gravity and the energy accumulated throughout the action.

    Acceleration Phase

    This phase of a basketball shot involves partially extending the knees and flexing the shoulder and elbow, positioning the ball in front of the forehead. It prepares for the powerful launch.

    Throw-in - Toe Drag Phase

    The 'toe drag' phase involves dragging the back foot across the ground before planting it for the throw-in. This helps generate power and control.

    Throw-in - Foot Plant & Arm Cocking

    This phase involves planting the front foot, cocking the ball back, bending the back, extending the arms, and releasing the ball.

    Throw-in - Follow Through Phase

    This phase of the throw-in involves following through with arm movements until kinetic energy dissipates. Maintaining the movement after releasing the ball.

    Basketball Skill Analysis - Key Points

    These are important elements to consider while analyzing a basketball skill like a shot or throw-in. Includes factors like the distance the hand can reach, the starting and ending positions of the body, the muscles used, the overall technique, and the range of motion of the joints.

    Study Notes

    Throwing Biomechanics

    • Preparatory phase: Body parts positioned for the throw, brain anticipates the movement
    • Main phase: All necessary actions to complete the throw, requiring neuromuscular coordination
    • Final phase: Object leaves the hand, body moves due to residual kinetic energy built up

    Baseball Throwing

    • Wind-up phase: Opposite knee to chest, concentric contraction of rotator cuff for compression and rotation
    • Stride phase: Anterior lunge, abduction and external rotation of the shoulder
    • Arm cocking phase: Trunk bending, adduction and internal rotation of the shoulder
    • Arm acceleration: Trunk bending, adduction, internal rotation, and extension of the shoulder, ball release
    • Arm deceleration phase: Trunk bending, eccentric contraction of the rotator cuff to prevent instability, elbow extension deceleration
    • Follow-through phase: Full body movement follows the trajectory of the throw until the hand almost touches the ground

    Basketball Throwing

    • Preparation phase: Dominant foot forward, hands holding the ball, visual information gathered before action
    • Acceleration phase: Knees semi-extend, shoulder and elbow flex to position ball in front of forehead.
    • Shooting phase: Knee and elbow extend, ball released
    • Flight phase: Wrist flexes, body returns to normal position due to gravity and accumulated kinetic energy
    • Toe drag phase: Arms brought forward, trailing foot dragged across the ground, front foot remains planted
    • Ball release: Trunk remains straight, arms fully extended forward, ball released
    • Follow-through phase: Follow-through movements continue until kinetic energy is used up

    Key Points for Throwing

    • Reach distance: Distance of the throw
    • Initial position: Starting posture for the throw
    • Final position: Ending posture for the throw
    • Muscle activation patterns: Patterns of muscle engagement during the throw
    • Technique: Method employed to execute the throw
    • Range of movement: Movement of different joints during the throw
