Dr Alasdair Dempsey
BSc(ExHealthSc)(Hons), PhD AES ESSAM

Senior Lecturer in Biomechanics and Sports Science

About me

Alasdair Dempsey is a Senior Lecturer in Biomechanics and Sport Science within the School of Psychology and Exercise Science.  He received his BSc (Hons) from the University of Western Australia and completed his PhD in anterior cruciate ligament injury prevention.  Prior to taking up his position at Murdoch Alasdair has worked as a researcher at The University of Western Australia and Griffith University.

Alasdair’s research focuses on understanding the neuromuscular biomechanics behind sports injury and musculoskeletal disease. He also had developed exercise based interventions for anterior cruciate injury based on modifying high risk neuromuscular biomechanics. This work is conducted with research groups from leading universities across Australia. Alasdair’s work on sports injury has been published in the top ranked Sports Science journals. It has received awards from both The University of Western Australia and national and local conferences, including the Young Investigator Award at the 2006 Australian Association for Exercise and Sports Science Conference.

Alasdair currently lectures in and coordinates EXS204 Biomechanics I, EXS304 Biomechanics 2, EXS569 Advanced topics in Exercise Physiology and BSC100 Building Blocks for Science Students.

He is also the Academic Chair for the undergraduate Exercise Science Programs and is currently Acting Associate Dean Learning and Teaching for the School of Psychology and Exercise Science.

Teaching area

BSC100 Building Blocks for Science Students

This unit is designed to provide students within the Bachelor of Science at Murdoch university the required skills to successfully complete their degree and for their future careers.

EXS204 Biomechanics 1

This unit teaches students principles of biomechanics and their application to human movement from both a theoretical and practical perspective. Examples are drawn from both the clinical and sporting realms.

EXS304 Biomechanics 2

This unit will develop students understanding of biomechanics and its application within both sport and clinical settings. It will focus on neuromuscular biomechanics and advanced biomechanical assessment techniques.

EXS569 Advanced Topics in Exercise Physiology

This unit covers biomechanics, ergonomics, functional capacity testing and the design of evidence based exercise interventions for AEPs.

Research areas

Sports Injury Prevention

This research involved identifying the neuromuscular biomechanical factors related to sports injuries and then developing specific training interventions to counter them.  This work is undertaken in conjugation with Griffith University, Monash University, University of Ballart and The University of Western Australia.

Prevention of Knee Joint Osteoarthritis

This work focuses on the identification of mechanical factors behind the development of knee joint osteoarthritis and the development of intervention protocols.

Current projects

Influence of velocity on full body kinematics and knee loading during sidestep cutting tasks

What is the influence of adherence to an injury prevention program on the neuromuscular biomechanics of three lower limb injuries?

The relationship between visual anticipation and hitting biomechancis in baseball.

What functional exercises promote increased medial muscle activation in knee joint osteoarthritis patients?
