Sports Biomechanics and Injury Prevention Research

The objective of the research laboratory is to study musculoskeletal biomechanics related to human health, mobility, and injury prevention. Research projects usually involve experimental measures of human movement dynamics, and often combined with computer-based modelling efforts. A key focus of the laboratory is the prevention of fall-related injury (e.g., traumatic brain injury, hip fracture, wrist fracture) in older adults. Particularly, we seek to understand biomechanical and physiological risk factors for injury and mobility impairment in older adults, and to develop and evaluate novel interventions for injury prevention. Our goal is to conduct high quality and evidence-based research that will lead to significant impact on people’s health and quality of life.


1. Examining Mobility Patterns and Fall Mechanisms in Older Adults
  • Physical activity monitoring (e.g., wearable sensors) and gait analysis (e.g., computerized walkway system) in older adults
  • Analysis on the biomechanics of falls (Fig. 1), in collaboration with the Injury Prevention and Mobility Laboratory at Simon Fraser University, Canada

2. Determining Risk Factors Associated with Injury
  • Biomechanical factors associated with the risk of injury (e.g., head, knee) in sports (Fig. 2)
  • Physiological and biomechanical risk factors for injuries (e.g., head injury, hip fracture) during falls in older adults (Fig. 3)

3. Developing and Evaluating Strategies for Injury Prevention
  • Physical activity programs to enhance mobility and strength in older adults (Fig. 4)
  • Protective gear for injury prevention (e.g., head gear, hip protector) (Fig. 5)
  • Education to increase public awareness and knowledge for injury prevention
