The Need

• 30 of U.S. deaths in 2000 due to lack of
  physical activity, smoking, and poor diet.
• 43.4 of elderly deaths caused by heart disease,
  stroke, and diabetes.
• 32.9 of elderly without physical exercise for
  the past month.
• 19.5 of elderly are obese.

5
The Solution

• The Viscocise
• The benefits of water aerobics on land

6
Advantages

• No stored energy
• Safer than weights or springs.
• Does not constrain motion
• Same degrees of freedom as the body
• Matches the force of the user
• Viscous damping acts as a passive feedback system
• Dual-direction resistance
• Exercises complementary muscle groups.

7
Calculations

• Maximum Torque 40 Nm
• Average Joint Rotational Speed 1 rad/s
• Linear Damper (10cm moment arm)
• Maximum Force 400 N
• Damping Coefficient 40 Ns/m
• Rotary Damper (11 gear ratio)
• Maximum Torque 40 Nm
• Damping Coefficient 40 Nms/rad

Market

• 35 million elderly in U.S.
• Increased physical activity could save 77
  billion in medical expenses.
• 95 of elderly health care spending on chronic
  diseases (i.e. diabetes, heart disease and
  stroke, cancer and arthritis).
