Understand How Different Foot Strikes
• Determine the force and impulse exerted with different foot strikes when running
• Understand how different foot strikes, flat foot, heel first, or toe first, can create different forces and impulses
Introduction:
Everyday runners across the country take off on their daily run. These runners tend to have different foot strikes when they run. The three types of foot strikes are heel first (landing on the heel), mid-foot (landing simultaneously on the heel and ball of the foot), or forefoot striking (landing on the ball of the foot). According to sports science 75% of runners land on their heel, 24% land mid-foot, and about 1% land forefoot first when running. When the body hits the ground, it generates an impact force. The force times the duration of the collision is the impulse. The impact force sends a shock wave up through the skeletal system, thus, the greater the force, the greater the shock wave and stress on the body (Running Technique). …show more content…
This force exists when walking and running. Each step when running produces a force two to three a person’s body weight, which could vary with different running strikes. According to Daniel E. Lieberman, during heel strike, the ankle is dorsiflexed. The middle to outside of the heel just below the ankle joint is landed on. As the foot is landed on, the toes begin to move towards the ground. During forefoot strike the toes point slightly down and the foot is slightly inverted. As the foot is landed on, the heel begins to move towards the ground and the outside of the forefoot is landed on. Midfoot strike is between heel strike and forefoot strike. The runner lands flat on their foot with little rotation and pushes off again with the ball of their foot. The way the foot lands when running can affect the force and impulse generated when landing and affect how much stress is put on the body
