The association between running kinematics and common overuse injuries in runners : implications for injury and rehabilitation (2020)
Thesis
Bramah, C. The association between running kinematics and common overuse injuries in runners : implications for injury and rehabilitation. (Thesis). University of Salford

Background: Running related injuries are influenced by a complex interaction between multiple factors. Running kinematic patterns represent one such factor which will influence the load applied to musculoskeletal structures during each foot contact o...

Prolonged sitting and physical inactivity are associated with limited hip extension : a cross-sectional study (2020)
Journal Article
Boukabache, A., Preece, S., & Brookes, N. (2021). Prolonged sitting and physical inactivity are associated with limited hip extension : a cross-sectional study. Musculoskeletal Science and Practice, 51, 102282. https://doi.org/10.1016/j.msksp.2020.102282

Background: It is possible that physical inactivity and prolonged sitting could lead to changes in muscle properties or bony limitations which may reduce passive hip extension.
Objectives: This study explored the association between passive hip ext... Read More about Prolonged sitting and physical inactivity are associated with limited hip extension : a cross-sectional study.

The effect of increasing trunk flexion during normal walking (2020)
Journal Article

Background: The head, arms and trunk segment constitute a large proportion of the body’s mass. Therefore, small alterations in trunk inclination may affect lower limb joint moments and muscle activation patterns. Although previous research has invest...

Between-day repeatability of lower limb EMG measurement during running and walking (2020)
Journal Article

There are minimal data describing the between-day repeatability of EMG measurements during running. Furthermore, there are no data characterising the repeatability of surface EMG measurement from the adductor muscles, during running or walking. The p...

The performance of an algorithm for classifying gym-based tasks across individuals with different body mass index (2020)
Journal Article
Gerrard-Longworth, S., Preece, S., Clarke-Cornwell, A., & Goulermas, Y. (2020). The performance of an algorithm for classifying gym-based tasks across individuals with different body mass index. Measurement in Physical Education and Exercise Science, 24(4), 282-290. https://doi.org/10.1080/1091367X.2020.1815749

Previous activity classification studies have typically been performed on normal weight individuals. Therefore, it is unclear whether a generic classification algorithm could be developed that would perform consistently across individuals who fall wi...

Could relative movement between the adductor muscles and the skin invalidate surface electromyography measurement? (2020)
Journal Article
Elsais, W., Preece, S., Jones, R., & Herrington, L. (2020). Could relative movement between the adductor muscles and the skin invalidate surface electromyography measurement?. Journal of Applied Biomechanics, 36(5), 319-325. https://doi.org/10.1123/jab.2019-0299

The superficial hip adductor muscles are situated in close proximity to each other. Therefore, relative movement between the overlying skin and the muscle belly could lead to a shift in the position of surface electromyography (EMG) electrodes and co...

Using the spring-mass model for running: Force-length curves and foot-strike patterns (2020)
Journal Article

Background: The spring-mass model is commonly used to investigate the mechanical characteristics
of human running. Underlying this model is the assumption of a linear force-length relationship,
during the stance phase of running, and the idea that... Read More about Using the spring-mass model for running: Force-length curves and foot-strike patterns.

How does normal variability in trunk flexion affect lower limb muscle activity during walking? (2020)
Journal Article
Alghamdi, W., & Preece, S. (2020). How does normal variability in trunk flexion affect lower limb muscle activity during walking?. Human Movement Science, 72, 102630. https://doi.org/10.1016/j.humov.2020.102630

A large proportion of the mass of the body is contained within the trunk segment. Therefore, small changes in the inclination of this segment have the potential to influence the direction of the ground reaction force and alter lower limb joint moment...
