- Use RevisionDojo for: Heart rate tracking, standard test procedures (e.g., Harvard Step Test), evaluation of variables.
3. The Effect of Music Tempo on Sprint Speed
- Why It Works: Mixes psychology and biomechanics—unique yet testable.
- IB Concepts: Arousal theory, reaction time, short-term power output.
- Use RevisionDojo for: Notes on arousal theories, controlled warmups, and power output calculations.
4. Does Warm-Up Type (Static vs Dynamic) Affect Vertical Jump Performance?
- Why It Works: Easily executable and ties directly to flexibility and muscle readiness.
- IB Concepts: Joint mobility, flexibility, muscle elasticity.
- Use RevisionDojo for: Flashcards on types of stretching and plyometrics, practical experiment design.
5. Reaction Time and Sleep Deprivation
- Why It Works: Taps into cognitive and neuromuscular domains.
- IB Concepts: Central nervous system, fatigue, and alertness.
- Use RevisionDojo for: Sleep science notes, reaction drills, and ethical data handling with peers.
6. Dominant vs Non-Dominant Hand Strength
- Why It Works: Easily measurable, simple equipment (dynamometer), high control.
- IB Concepts: Muscular strength, laterality, reliability in testing.
- Use RevisionDojo for: Test-retest protocols, muscle physiology, and gender considerations in results.
7. Resting Heart Rate Changes from 5-Minute Meditation
- Why It Works: Integrates mental health and performance—relevant, measurable.
- IB Concepts: Parasympathetic nervous system, heart control.
- Use RevisionDojo for: Notes on autonomic responses, and designing calm testing environments.
8. Effect of Footwear Type on 20m Sprint Time
- Why It Works: Focuses on biomechanics and friction—real-world relevance.
- IB Concepts: Frictional force, stride efficiency, muscle contractions.
- Use RevisionDojo for: Biomechanics flashcards, analysis of external factors (surface, shoes).
9. Gender Differences in Balance Test Performance
- Why It Works: Simple test, yet allows meaningful data analysis.
- IB Concepts: Motor learning, proprioception, center of mass.
- Use RevisionDojo for: Lab procedures on stork balance tests and interpreting balance outcomes.
10. Relationship Between Arm Span and Swim Time
- Why It Works: Connects anthropometrics to athletic performance.
- IB Concepts: Body proportions, levers in movement.
- Use RevisionDojo for: Notes on biomechanics, anthropometry, and fair testing.
