🏊‍♀️ Understanding Swimming Efficiency

🎯 SWOLF Score

  • What it is: Time (seconds) + Strokes per length
  • Lower is better: Indicates efficiency
  • Elite swimmers: 20-25 in freestyle
  • Intermediate: 30-40 range typical
  • Pool dependent: Short course = lower SWOLF

💪 Stroke Rate

  • Distance swimming: 45-55 strokes/minute
  • Middle distance: 50-65 strokes/minute
  • Sprinting: 65-85 strokes/minute
  • Triathlon: 40-50 strokes/minute
  • Masters: Often 40-55 for endurance

📊 Distance Per Stroke

  • Elite freestyle: 2.0-2.5m per stroke
  • Advanced: 1.8-2.2m per stroke
  • Intermediate: 1.5-2.0m per stroke
  • Beginner: 1.2-1.8m per stroke
  • Stroke efficiency: Balance distance and rate

⚡ Efficiency Factors

  • Streamlining and body position
  • Catch and pull technique quality
  • Kicking efficiency and rhythm
  • Breathing patterns and timing
  • Consistency and relaxation
