2
Biomechanics Technology

• A few new technology items out now in regards to
  biomechanics
• Not necessarily in sports
• Picked items that sparked our own interest

3
Intro

• Adidas 1 Running Shoes
• Quill Mouse
• Medilogic Foot Pressuring Measuring System
• Oxysox
• E3 Fitness Grips

4
Adidas 1 Running Shoes

• 15 billion dollar market

5
Running shoes compression Why?

• Cushioning shoes means of decelerating the
  runners foot when heel strikes ground
• Impulse-Momentum Relationship Ft m (vf vi)
• Too hard foot slows too quickly shock felt in
  knees
• Too soft foot bottoms out and strikes ground
  too hard another shock in the knees

6
Compressioncont

• Gel pads, air chambers, variable-density-foam
  mid-sole platforms, metal springs in hell
• But Clarissa Flockhart doesnt weigh the same as
  Warren Sapp!

Development of Adidas 1

• Adidas innovation team in Portland
  Herzogenaurach started in 2001
• 3 years highly confidential in house development
  (50 people names not available to public)
• Goal to make shoe adjust to changing conditions
  and runners particular style while in use

8
Development of Adidas 1cont

• 1st ideal cushioning range for runners?
• sensor in top of heel of standard running shoes
  smaller magnet in bottom of heel creating a
  magnetic field that the sensor could measure
  (Hall sensor)
• Then invited testers to select shoes that felt
  were most comfortable people were picking the
  same range of compression

9
Development of Adidas 1cont

• Shoe has a battery-powered sensor,
  microprocessor, and electric motor

10
The sensor -

• Battery-powered sensor accurate to .1mm, 20,000
  readings/second
• Must change every 100 hours of use

11
The microprocessor -

• Microprocessor is the embedded electronic brain
  which can make 10,000 calculations per second
  which directs the electric motor to change the
  cushioning of the shoe

12
The motor

• Electric Motor corrects cushioning throughout the
  run
• Turns a screw that adjusts degree of cushioning

13

14
Other features -

• Also, will have push-button controls,
  light-emitting displays with the settings
• Instruction manual on CD-Rom

15

Quill Mouse
18
Repetitive Stress Injury

• Disorder that occurs from prolonged, repetitious
  use of the hands
• Results in pain, burning, swelling, weakness,
  tingling, numbness, and a loss of dexterity
• Example Carpal Tunnel Syndrome
• Inflammation of the tendons and synovial sheaths
  within the carpal tunnel, ultimately leading to
  the compression of the median nerve

19
Who are most at risk?

• People who use computers
• Why?
• Gripping of computer mice interrupts muscle
  function
• Most mice do not support the wrist and hand
• Wrists are constantly flexed, causing strain
  (static posture)
• Using an ordinary mouse for more than 20 hours
  per week will likely lead to injury within 2-5
  years
• Postural Compensation

20
The Solution

• The Quill Mouse!

21

What OxysoxTM does

• Reduces leg fatigue/pain post exercise
• Gives better stability for injury prone areas
• Increases calf muscle pump efficiency

• Reduces Blistering
• Is more durable outlasts standard socks 3-4
  time longer
• Wicks sweat away
• More.

37
The construction of OxysoxTM
38
How OxysoxTM works

• OxysoxTM applies pressure to the lower
  extremities starting with the foot and narrowing
  off at the calf. This graduated pressure allows
  blood to return more rapidly to the heart and
  lungs the result is improved circulation and a
  quicker return of oxygenated blood to the legs
  enhanced athletic performance.

39
How OxysoxTM works

• OxysoxTM also limits unnecessary muscle motion
  thereby keeping muscles intact, reducing fatigue,
  and allowing for quicker recovery.
• The construction of the OxysoxTM offers support
  to the Achilles tendon, ankle, calf, and tibia.
  The support enhances the ability to reduce common
  foot and ankle injuries and provides support to
  those already injured.

Changing the Science of Body Movement

• Stephen Tamaribuchi, a consultant for the
  prevention of repetitive stain injuries developed
  the e3 Fitness Grip he has over twenty-years of
  experience in the field of human biomechanics and
  has worked with both sport and corporate
  athletes. Mr. Tamaribuchi served as a consultant
  to companies such as Microsoft, Apple, and HP.
  As a trainer, he worked with the CSU Sacramento
  Football team, tennis player Rod Laver, and
  six-time winner of the Hawaii Iron man Triathlon
  Dave Scott. Mr. Tamaribuchi earned both his
  Bachelors and Maters degrees from CSU
  Sacramento and also studied shiatsu acupressure.

44
What the e3 Fitness Grips Do

• Stabilizes the shoulder, back, and hips
• Distributes weight more evenly throughout the foot

45
What the e3 Fitness Grips Do

• Causes weight to shift in a tighter formation
  closer to the midline of the body as well as in
  the foot weight closer to the midline allows
  muscle recruitment to be more efficient
  throughout the leg, and body control is increased
  by using the e3 Fitness Grips. Efficient muscle
  recruitment also indicates an increase in
  stability for the foot, ankle, knee, hip, and
  back.

46
How the e3 Fitness Grips Work

• The e3 Fitness Grips work on the principle of
  stabilizing the shoulders, back, and hips.
  During normal use the average person displaces
  the shoulders, then the back, which in turn
  shifts the hip position. The hips and back are
  not always stable to start with, which makes the
  shoulder girdles susceptible to the forces that
  would pull it into an unstable position.

Weight is shifted to the right Right shoulder is
dropped and so the back arches to compensate The
Right hip is dropped, primary muscle use in the
legs is lateral Right knee is rotated
outward Right foot angles away from the midline
of the body
47
How the e3 Fitness Grips Work

• The e3 grips help modify mechanical behavior
  throughout the body by placing the shoulder and
  hip girdles in more natural stable positions and
  the axial skeleton in a balanced vertical
  alignment.
• Weight stays over the midline shoulders
  are more stable and in a more level position
  hips are level knee tracks straight ahead
  (directly over the foot and under the hip), and
  the right foot aligns with the mid-line of the
  body and in the direction of travel.

48
How the e3 Fitness Grips Work

• The natural stable position of the body is
  possible because the grip retrains the specific
  contraction pattern of a persons fingers, thumb,
  and wrist into a neutral position that results in
  better body control, improved balance, and better
  results with less effort.

49
Product design

• One type one-size-fits-all
• The design of the fitness grip is based on the
  palm width, which varies much less than the palm
  and finger length in most people.
