Dr Josh Walker

Senior Lecturer

Josh is a Senior Lecturer in Sport & Exercise Biomechanics in the Carnegie School of Sport. His research interests include muscle-tendon mechanics, chronic neuromuscular responses to loading and injury, and improving the accuracy and reliability of measurement techniques in biomechanics.

Having completed his undergraduate and postgraduate degrees in Sport & Exercise Science and Sport & Exercise Biomechanics, respectively, Josh remained at Leeds Beckett for his Ph.D., which investigated muscle-tendon neural and mechanical function during cycling. During his Ph.D. studies, Josh undertook a full-time role as Lecturer in Sport & Exercise Biomechanics at Leeds Beckett University in September 2020, before moving permanently to Senior Lecturer in September 2021. As part of his role, Josh delivers Applied Biomechanics services to local sports clubs, focussing primarily on isokinetic strength measurements during rehabilitation.

From a teaching perspective, Josh has introduced topics such as the analysis of musculoskeletal ultrasound images, the collection of dynamic ultrasound data during human locomotion, and basic programming skills to biomechanics curricula in both our undergraduate and postgraduate provisions. Josh is currently module leader for Measurement Techniques in Biomechanics (Level 7) and Biomechanical Determinants of Sports Performance (Level 5) but contributes to various other modules such as Neuromuscular Biomechanics (Level 7) and supervises biomechanics dissertations at undergraduate and postgraduate levels.

Research Interests

Josh's research interests span muscle-tendon mechanics and the chronic adaptations to loading and injury. Specifically, Josh employs static and dynamic ultrasonographic techniques to quantify muscle-tendon properties during human movement, often in combination with other biomechanical measurement systems (e.g., motion capture, isokinetic dynamometry). His experience using ultrasound in biomechanics has seen Josh deliver talks to institutions such as the European School of Physiotherapy (Amsterdam, The Netherlands). Recently, Josh has been leading collaborative research into Controlled Ankle Motion (CAM) boots, seeking to understand how they can be optimised to improve the rehabilitation of injuries such as Achilles tendon ruptures and diabetic foot ulcerations. Josh is also interested in the accuracy and reliability of biomechanical measurement systems both inside and outside the laboratory, and has a publication record of data collection in "real-world" settings.

Josh's research interests and experience means he sits across both 'Musculoskeletal and Orthopaedic Sports Medicine' and 'Optimising Endurance Performance' research themes within the Centre for Human Performance.
