Introducing the Biomechanical Engineering in Sports Laboratory
Research conducted in this laboratory concentrates on two different sports. One sport is cycling. Within this sport, the research has two different themes--
The other sport is skiing/snow-boarding where the interest is on prevention of injuries.
- Cycling biomechanics with applications for performance optimization and overuse knee injury prevention.
- Design and optimization of bicycle structural components and suspensions.
On-going Research Projects
Functional roles and forces produced by muscles of the lower limb
Forward dynamics simulation of the cycling movement
Identification of determinants of cycling performance
Relationship between anatomic and equipment set-up variables on 3-D intersegmental knee loads and vastii activation.
Structural Components and Suspension
Quantification of structural loading during actual on and off-road cycling
Development and application of cumulative damage models for the prediction of resistance to fatigue failure.
Development of mathematical models which describe the dynamic response of the bicycle-rider system.
Optimization of suspension parameters through both dynamic simulations of bicycle-rider system response and experiments using adjustable parameter mountain bikes.
Dynamic modeling and simulation of falls.
Measurement of injury governing variables during actual skiing and snowboarding. Injury governing variables include loads transmitted between ski/board and boots, joint angles and muscle excitations.
Mechanics of injury to musculo-skeletal components particularly the ligaments of the knee.
Design of computer-controlled released bindings for Alpine skiing
Research is sponsored by a number of companies which are industry leaders. Among these are Shimano, Trek, GT, Specialized, Rock Shox, and Tyrolia. Research is also sponsored by the United States Olympic Committee.
