  1. EXER-STATION Bichar Myrtil Tarafa M. Al-Awaj

  2. ISSUE "We have noticed that children in America are tending more toward obesity [& general less fitness] than in decades past; Part of it is due to sedentary lifestyles that kids are getting into. Rather than run in the woods, they've got Game Boy, Nintendo and television." - Discovery_Channel.com/Health Dec 2003

  3. Issue • Children’s Hospital has realized that patients spend majority of time playing video games • In addition, most patients (i.e. PKU patients) have physical handicaps • Usually have minimal exercise in a day • Deterioration in general health

  4. TARGET PATIENTS • Specially designed for PKU patients in the Vanderbilt Children’s Hospital • Inability of the body to utilize the essential amino acid, phenylalanine • Chronically high levels of phenylalanine and some of its breakdown products can cause significant brain problems • Signs of nervous system function problems, such as increased muscle tone, and more active muscle tendon reflexes and decreased body growth

  5. TARGET PATIENTS (cont’d)STATISTICS • One of every 10,000 to 20,000 Caucasian or Oriental births (the incidence in African Americans is far less) • Equally frequent in males and females • ≈ 27,200 individuals in the USA only

  6. TARGET PATIENTS (cont’d)PARAMETERS • Limited IQs ( < 80 ) “Special” • Some Physical Limitations • Lower Socio-Economic Background (limits financial resources) • Parents Usually Low in Motivation • Other Limited Resources (e.g., education)

  7. Alternate Solutions • DRUG ADMINSTRATION (e.g., Amphetamines) • Adverse Psychological Effect/Damage • Possibly Addictive (Dependency) • PERSONAL TRAINER/THERAPIST • Expensive (Cost Factor) • Lack of Independent Motivation

  8. Solution Incorporate an amount of physical aerobic activity into video play + Incorporate ‘leg-activated’ commands instead of ‘finger-activated’ + Independent Exercise + Patient can remain sedentary + Aid in improving patient health and morale ________________________________________ = EXER-STATION

  9. “Pedal power energy has been in use since the nineteenth century. Pedal power uses the most powerful muscles in the body: the quads, hamstrings, and calves. When pedaling in a circular motion at sixty to eighty revolutions per minute, with the use of toe clips, almost every muscle in the human legs can be used to make energy.” -Wilson 1977

  10. MODEL of EXER-STATION

  11. CONTROLLER • North and South of the Left analog stick will be replaced by pedal motion. • All other commands will remain intact and function through hand controller.

  12. RESISTANCE • Volare Mag Trainer w/Elastogel and Remote • Magnetic resistance unit with 5 different levels of adjustment

  13. DC GENERATOR Output from generator will be smoothed and scaled to produce a DC current from -3V to +3V for maximum backward/forward (down/up) motion respectively.

  14. ADDITIONAL PARAMETERS • TIRE DIAMETER= 24” (Unicycle Wheel w/ Pedals Directly Attached) • Speed Range 40-120 RPM • Below:- Strains joints • Above:- Efficiency falls off

  15. EXTRA PARAMETERS (CONT’D) • Shaft 8mm diameter • Armature 52mm diameter • Rpm2 = (d1/d2) * Rpm1

  16. GAMEPLAY • Design and Tested To Work Best w/ Motion Games or Simple Maneuver (Racecar, 1st Person-Action, etc)

  17. AIMS 1 hour of Exer-Station = 20 minute Brisk Walk 4 minute Sprint Approximately 86 Calories!

  18. Results? • Kids play ≈ 6 hours/day • Use ≈ 100 Calories/hour • Expend ≈ 600 Calories/day!!!

  19. MARKET POTENTIAL • Ages 8+ • Hospital Patients • Obese Individuals • Individuals concerned about fitness • General Video Game Audience

  20. TIME CHART

  21. BUDGET • $400 Initial Budget (from Dr. Summar) • Playstation II Console ($200) • Multiple Controllers ($75) • Three Games ($150) • Additional $350 Requested (from Dr. King’s Grant) • Leg Activated Elements • Unicycle ($125) • Mag. Trainer ($150) • DC Generator ($25) • Wires • LEDs • Chips • Circuit Board • Decorative Design/ Aesthetics • Miscellaneous

  22. RESOURCES ADVISORS • Paul H. King, PhD., P.E.: -Associate Professor of Biomedical Engineering at Vanderbilt. -Associate Professor of Mechanical Engineering at Vanderbilt. -Associate Professor of Anesthesiology at Vanderbilt. -Instructor of the senior Biomedical Engineering design course at Vanderbilt. • Marshall Summar, M.D.: -Associate Professor of Pediatrics at Vanderbilt. -Associate Professor of Molecular Physiology & Biophysics at Vanderbilt. VANDERBILT UNIVERSITY -lab space -machine shop -research facilities -software -help purchase necessary tools/equipment SECOND BASE -back-up location when primary lab not available
