HAMMER THROWBy: Jamie Crouse & Amber Topil
Skill Objective• Accelerate the steel ball as quickly as possible to
maximize distance
FactsMen’s Hammer• Weight: 16 pounds• Length: 3’ 11.75”• World Record: 285’ 7”
Women’s Hammer• Weight: 8.8 pounds• Length: 3’ 11”• World Record: 260’ 6”
The Field• Cage• Ring• Sector
Equipment• Glove • Hammer • Shoes
The Grip
Phases
1. The wind
2. The entry
3. The turns
4. The finish
Phase 1: The Winds• Initiate momentum of the throw
• Muscles used: triceps, deltoid, biceps, trapezius, external and internal oblique, and latissimus dorsi
Phase 2: The Entry• Athlete enters the turning phase
• Muscles used: flexor group, soleus, tibialis posterior, gastrocnemius, hamstrings, and quadriceps.
Phase 3: The Turns• A series of 3 or 4 turns to increase the speed of the
hammer.• Heel-toe turns• Muscles used: lower half of the body and flexed
abdominals
Phase 4: The Finish• Drive the hammer upward
• Muscles used: quadriceps, gluteal muscles, gastrocnemius, soleus, tibialis posterior, trapezius, deltoid, and obliques
Path of the Hammer Ball
Optimum Distance
Dependent on:• Height of release• Angle of release• Speed of release
Common Errors• Not turning the right foot• Catching the toe on the heel• Pulling with your left arm • Arms flexed • Not flexing the knees
