Purpose

• Strength, speed and power
• Heightened excitability
• KNOW THE STRETCH REFLEX
• Force maximized
• Minimize reaction time
• Why important?

11
Plyometric Progression

• Low Intensity
• In place plyometrics
• Jumps, hops
• May include some lateral movements
• Medium Intensity
• Bounds, multiple response jumps
• High Intensity
• Shock activities, depth jumps, box drills, sport
  specific drills, position specific drills
