Study Notes
Measuring Motor Skills and Abilities
- Assessing motor skill and ability is crucial for tracking progress, identifying strengths and weaknesses, informing coaching strategies, enhancing motivation, and setting goals.
- Key factors for valid measurements include:
- Validity: The measure must accurately reflect the intended skill or ability.
- Reliability: Results should be consistent across repeated trials.
- Objectivity: Measurements should be unbiased and quantifiable.
- Accuracy: Precision in measurement tools and methods is essential.
Differentiating Response Outcome and Response Production
- Response Outcome Measures: Focus on the result of a movement (e.g., goals scored, distance covered, time taken).
- Response Production Measures: Focus on the mechanics behind the movement (e.g., joint angles, muscle activation, trajectory).
Measuring Error in Motor Skills
- Errors provide feedback for improving performance.
- Constant Error (CE): Measures the average deviation from a target, considering direction. Formula: CE = Σ(xi - T) / n (where xi = result and T = target, and n = number of trials). Identifies performance biases or tendencies.
- Absolute Error (AE): Measures average deviation from the target, ignoring direction. Formula: AE = Σ|xi - T| / n. Focuses on overall accuracy.
- Variable Error (VE): Measures the inconsistency or variability in performance. Formula: VE = Σ(xi - M)2 / n (where M = mean of scores). Reflects performance stability.
Reaction Time (RT) as a Measure
- Reaction time (RT) is a crucial measure of motor learning and ability.
- RT components:
- Premotor Time: Time between stimulus and muscle activation (information processing).
- Motor Time: Time between muscle activation and movement (mechanical delay).
- RT reflects information processing speed and readiness for movement.
Talent Identification
- Talent identification aims to predict athletic potential through measuring abilities and skills.
- Challenges include difficulty in measuring relevant abilities and predicting long-term growth and adaptability to training.
- High performers often excel in combining or utilizing core abilities in unique ways.
- Assessment tools like the NFL or NHL combines use measurable attributes but may not fully predict long-term success.
Examples of Application
- Rugby Passing:
- Outcome: Distance and accuracy of the pass.
- Production: Hand positioning, arm trajectory, and grip mechanics.
- Sprinting Performance:
- Outcome: Time to complete a sprint.
- Production: Joint angles, force application, and stride frequency.
