Study Notes
Construct Validity
- Definition: The ability of a test to accurately represent the construct or theory being measured.
- Importance: Ensures the test is relevant to the specific athlete's performance. (e.g., speed for a football wide receiver)
- Example of High Construct Validity: A 40-yard sprint for a wide receiver.
- Example of Low Construct Validity: An 800-meter sprint for a wide receiver, as it doesn't measure speed relevant to their role.
Types of Validity
- Face Validity: Does the test appear to measure what it should? Important for athlete buy-in.
- Content Validity: Assessment by experts on whether the test covers all relevant components appropriately.
- Criterion-Referenced Validity:
- Concurrent Validity: Comparison with other measures taken at the same time.
- Convergent Validity: Agreement with other valid measures.
- Predictive Validity: Ability to predict future performance.
- Discriminant Validity: Differentiation from unrelated constructs.
Reliability
- Definition: The consistency of a measure; essentially, reproducibility.
- Key Concepts:
- Intra-Rater Reliability: Consistency of the same rater measuring a test multiple times.
- Inter-Rater Reliability: Consistency between different raters measuring the same test.
Terminology
- Intra: Within a single subject (e.g., same person taking the test).
- Inter: Between multiple subjects or raters (e.g., different people scoring the same test).
Summary
- Construct validity is critical for ensuring tests accurately reflect an athlete's skills.
- Reliability complements validity by ensuring measurements are consistent, focusing on intra- and inter-rater reliability for accuracy in scoring.
Key Environmental Factors
- Temperature: High heat can impair performance.
- Humidity: Greater than 50% can negatively affect endurance tests.
- Altitude: Significant for athletes transitioning from sea level.
Testing Guidelines
- Heat and Humidity: Performance may be impaired when temperatures exceed 80°F and humidity exceeds 50%. Testing can still occur, but with caution.
- Altitude Acclimatization: Athletes moving to high altitudes from sea level should acclimatize for 10 days before undergoing aerobic tests. This period allows the body to adjust and achieve homeostasis.
- Recommendations: Highlight temperature and humidity thresholds in your materials. Always plan for acclimatization when testing at altitude.
Notes on Battery of Tests and Test Administration
- Definition of Battery of Tests: An organized sequence of tests used to assess various performance attributes.
- Protocol: Important to follow a consistent order during testing.
- Maximizing Test Reliability:
- Preparation: Athletes should be familiar with the tests and procedures.
- Practice: Conduct practice sessions before the actual tests to enhance familiarity.
- Warm-Up Importance:
- Types of Warm-Ups:
- General Warm-Up: Increases overall body temperature and prepares the body for activity.
- Specific Warm-Up: Focuses on the muscles and movements that will be used during the tests.
- War-Up Benefits: Improves test reliability and performance.
- Consistency in Testing:
- Same Conditions: Maintain similar testing conditions (temperature, humidity etc.) across sessions.
- Standardization: Follow the same procedures and order for each testo ensure accurate comparisons over time.
- Types of Warm-Ups:
Key Takeaways
- Familiarity and preparation are critical for reliable testing.
- Always incorporate proper warm-ups.
- Keep environmental conditions as consistent as possible to avoid influencing test outcome.
Chapter 13: Administration, Scoring, and Interpretation of Selected Tests
- Types of Strength Tests:
- Maximum Muscular Strength (Low Speed Strength): One-rep max (1RM) for squat, bench, deadlift, isometric movements.
- Anaerobic (Maximum Muscle Power): High-speed strength tests like power cleans, hang snatches, explosive lifts.
- Anaerobic Capacity: Ability to perform high-intensity activities without oxygen (typical test duration 30-90 seconds).
- Local Muscular Endurance: Measure how many repetitions can be completed to failure or in a set time (e.g., chin-ups, pull-ups, push-ups).
- Aerobic Capacity: Body's ability to take in and deliver oxygen (tests: 1-mile run, Yo-Yo intermittent test, laboratory VO2 max test).
- Agility Tests: Focus on change of direction (tests: T-test, pro agility).
- Speed Tests: Time taken to cover a distance (e.g., 40-yard sprint, 100-meter sprint)
- Flexibility
- Balance and Stability
- Body Composition (Measurement methods: Bioelectrical impedance, skinfold measures)
Additional Notes
- Important aspects for reliable testing: familiarity, preparation, maintaining appropriate testing conditions.
- Standardization and using normative data to assess performance.
- Proper test procedures for each test.
- Statistical evaluation of test data (Descriptive Statistics).
- Developing an athletic profile (factors to evaluate).
- Test selection (valid and reliable tests, consistent administration).
- Post-assessment (repeat tests).
