Foundations of Swimming Science

Understanding the physics that make swimmers fast

Week 1-2 Hydrodynamics Basics

Key Concepts to Learn

  • Drag forces: form drag, friction drag, wave drag
  • Why body position is the #1 factor in swimming speed
  • Frontal area and its relationship to resistance
  • The "hull speed" concept for swimmers
Practical Application

Watch Jayden swim and identify moments of increased drag. Use underwater video (phone in waterproof case) to analyze body position. Compare his streamline to elite 10&U swimmers on YouTube.

Week 3-4 Propulsion Fundamentals

Key Concepts to Learn

  • Newton's Third Law in swimming
  • "Anchoring" the hand vs. "slipping" water
  • The catch phase: early vertical forearm (EVF)
  • Pitch, angle, and hand acceleration

Key Takeaways

  • The hand should "anchor" in place while the body moves past it
  • Acceleration through the pull is more important than raw power
  • The forearm is as important as the hand for propulsion
