Biomechanics & Technology
  • A few new technology items out now in regards to biomechanics
  • Not necessarily in sports
  • Picked items that sparked our own interest
  • Adidas 1 Running Shoes
  • Quill Mouse
  • Medilogic Foot Pressuring Measuring System
  • Oxysox
  • E3 Fitness Grips
adidas 1 running shoes
Adidas 1 Running Shoes
  • 15 billion dollar market
running shoes compression why
Running shoes compression – Why?
  • Cushioning: shoe’s means of decelerating the runner’s 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
compression cont
  • Gel pads, air chambers, variable-density-foam mid-sole platforms, metal springs in hell
    • But Clarissa Flockhart doesn’t weigh the same as Warren Sapp!


development of adidas 1
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 runner’s particular style while in use
development of adidas 1 cont
Development of Adidas 1…cont…
  • 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
development of adidas 1 cont1
Development of Adidas 1…cont…

Career & Internship Opportunities at Adidas…
repetitive stress injury
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
who are most at risk
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”
the solution
The Solution…

The Quill Mouse!

what oxysox tm 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


What OxysoxTM does
how oxysox tm works
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.
how oxysox tm works1
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
“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 Bachelor’s and Mater’s degrees from CSU Sacramento and also studied shiatsu acupressure.
what the e 3 fitness grips do
What the e3 Fitness Grips Do
  • Stabilizes the shoulder, back, and hips
  • Distributes weight more evenly throughout the foot
what the e 3 fitness grips do1
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.

how the e 3 fitness grips work
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

how the e 3 fitness grips work1
How the e3 Fitness Grips Work
  • The e3grips 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.

how the e 3 fitness grips work2
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 person’s fingers, thumb, and wrist into a neutral position that results in better body control, improved balance, and better results with less effort.
product design
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.
