  • Break the skill into its essential components.

  • Focus on elements critical to successfully executing the skill.

  • Performance Evaluation:

  • Identify performance errors.

  • Determine sources of these errors.

  • Prescriptive Corrections:

  • Suggest adjustments or modifications based on identifying the underlying causes of performance errors.

1.6 Kinesiological Analysis Framework (TABLE 1.1)

A. Description of Motor Skill Performance

1. Primary Skill Purpose: Analyze the skill with respect to its objectives in speed, accuracy, and form.

2. Movement Phases: Decompose motion into distinct phases, such as:

   • Preparation Phase: The initial setup for execution.

   • Power Phase: High-energy execution segment.

   • Follow-Through Phase: Completion and recovery of the movement.

3. Classification of the Skill: Categorizing skills to reveal anatomical and mechanical relationships within various skill groups.

4. Movement Nature:

   • Simultaneous Movement: Multiple segments of the body move cohesively.

   • Sequential Movement: Segments move in a deliberate, successive order.

B. Anatomical Analysis

1. Joint Actions and Segment Motions:

   • Identify involved joints and specific movements during the skill performance.

   • Assess any limitations in range of motion.

   • Reference specific tables for muscle and joint data (e.g., Table 1.2).

2. Muscle Participation:

   • Identify muscles engaged in joint actions during skill execution.

   • Classify types of muscle contractions involved (e.g., isotonic, isometric).

3. Neuromuscular Considerations: Determine the neuromuscular mechanisms engaged and their roles in the performance of the skill.

4. Anatomical Principles:

   • Examine which anatomical principles promote efficiency and accuracy in execution.

   • Discuss principles related to injury prevention.

C. Mechanical Analysis

1. Underlying Mechanics:

   • Balance: Actions to maintain stability or regain stability during skills (e.g., jump stops).

   • Locomotion: Movement actions involving travel, such as walking or running.

   • Projection: Investigates aspects of height, range, and accuracy in projects like throwing or jumping.

   • Manipulation: Involves skills with objects or body resistance (e.g., weightlifting).

   • Maximum Effort: Skills requiring high levels of speed, power, and force (e.g., sprinting).

2. Forces: Identify various forces acting during the motion, encompassing:

   • Internal Forces: Forces generated within the body.

   • External Forces: Environmental forces acting upon the body.

   • Modifying Forces: Any forces altering motion dynamics.

3. Critical Elements Identification: Key aspects of movement must be identified for effective skill performance analysis.

4. Mechanical Principles: Apply principles relevant to:

   • Safety of motion.

   • Effectiveness of performance.

   • Efficiency in energy use during actions.

D. Performance Improvement Prescriptions

• General Strategy: Provide insight on how to modify performance to adhere to effective principles, ensuring that ethical and practical considerations are present.

• Focus on Causes: Concentrate on root causes of errors rather than their superficial symptoms to facilitate effective improvement strategies.
