Question
How can an athlete improve their technique by letting science work for them instead of against them?
How do a runner’s shoe and friction affect a run?
(Newton’s 3rd Law: For every action there is an equal and opposite reaction.)
(Newton’s 1st Law: An object in motion will stay in motion unless acted upon by an outside force.)
Running
Means terrestrial motion allowing humans and animals to move rapidly
At one point in the circular motion, both feet are off the ground
Speeds range from a person’s jog to sprintKinetic and potential energy occur
simultaneously in stride
Footstrike
Occurs when foot makes contact with ground
Footstrikes: 1. Forefront
2. Midpoint 3. Heel Strike
Impacted Joints: 1. Hip 2. Knee 3. Ankle
Running Cycle
1. Footstrike2. Midstance3. Propulsion phase4. Swing Phase
Midstance
Knee flexion is under the trunk (bottom) and propulsion begins
Hip and knee extendPropulsion Continues until leg extends
backMaximum hip and knee extensionToe offResult: Body moves forward and initial
swing begins
*Propulsion means to push forward
Propulsion Phrase
Involves beginnings at midstance until toe off
Bodies store energy to propel forwardBig hip extensionWhere we get the biggest pay out in
running
Swing Phase
The start of the limbs returnKnee bends slightly as it swings to other
part of bodyOne side is toe off/propulsion other side is
swing/recovery
Newton’s Laws in Running
Friction with running shoe: The grip of a runner’s shoe against the ground
Laws: As the runner’s foot and shoe hit the ground, the grip from the shoe to the ground and the force of the body going back, propel the runner forward. Without the grip from the shoe, the runner would slip and slide all over the place.
Shoes I Researched
Brooks AsicsNew Balance
Saucony
Results
After Research I found:1. Trail running shoes have a better grip to
ground surfaces2. Different styled shoes serve different
purposes3. New Balance would be the ideal shoe to
buy in matters of friction or grip to the ground
Connection to Engineering
Different shoes have different styles and traits that make them unique. Engineers need to consider:
Gender, males and females have different bodies and running styles/traits/habits
The purpose of the shoe, trail running, heel support, comfort etc…
The shoe must be designed to withstand the force or impact of the runner
Finally the fit to a person’s foot
Answer
1. Science can work for a runner in their shoes if they find a shoe that can take their force or impact.
2. Also, if the runner doesn’t have enough friction or grip to the ground with their shoes, the are more susceptible to falling or tripping.
