The Viscocise Making Exercise Accessible to EVERYONE ! Section Yellow-B

Overview n The Need n The Device n Lessons Learned q Kinematics q Calculations q Next Iteration n Market Analysis

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

The Solution The Viscocise The benefits of water aerobics on land

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

Calculations n Maximum Torque: ~40 Nm n Average Joint Rotational Speed: ~1 rad/s n Linear Damper (10cm moment arm): q Maximum Force: 400 N q Damping Coefficient: 40 N•s/m n Rotary Damper (1:1 gear ratio): q Maximum Torque: 40 N•m q Damping Coefficient: 40 N•m•s/rad

Preliminary Testing Sketch Model

The Next Iteration n Damper Selection q Rotary damping for elbow joints q Oil-based dampers n Proper Ergonomics q Mirror human joints q Dual support handle to eliminate torque on wrist n Contact: Kristina Martin Director of Aquatic & Fitness Programs Zesiger Sports and Fitness Center

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