Journal Article
Pearson, S., Burgess, K., & Onambele, G. (2007). Creep and the in vivo assessment of human patellar tendon mechanical properties. Clinical Biomechanics, 22(6), 712-717. https://doi.org/10.1016/j.clinbiomech.2007.02.006

Background: Owing to the viscoelastic nature of tendons it may be that the total excursion and hence strain experienced by the tendon under load may be affected by the duration of contraction. Here we examine the effect of contraction duration on the... Read More about Creep and the in vivo assessment of human patellar tendon mechanical properties.

Aim: To examine the time-of-day (TOD) effect on torque–force/angle, fibre length (FL), tendon stiffness (K), stress, and strain using the quadriceps muscle–tendon complex as a model. Methods: Twelve healthy young men (aged 27±2.0 years) were stu...

Power output and muscle myosin heavy chain composition in young and elderly men (2006)
Journal Article
Pearson, S., Cobbold, M., Orrell, R., & Harridge, S. (2006). Power output and muscle myosin heavy chain composition in young and elderly men. Medicine and Science in Sports and Exercise, 38(9), 1601-1607. https://doi.org/10.1249/01.mss.0000227638.75983.9d

Purpose: Aging is associated with a decline in muscle volume, power output, and the velocity at which peak power (Vopt) occurs. The current study aimed to examine the relationship between lower-limb power output characteristics, muscle myosin heavy c...

We investigated the importance of tendon stiffness on estimations of central activation capacity (CAC). Patella tendon-force elongation relationship, quadriceps torque, and response to 50-micros, 100-HZ electrical twitch doublets were studied at appr...

Lower limb stiffness: Considerations for female athletes
Journal Article
McMahon, J., Comfort, P., & Pearson, S. Lower limb stiffness: Considerations for female athletes. Strength and Conditioning Journal, 34(5), 70-73. https://doi.org/10.1519/SSC.0b013e318268131f

Women demonstrate lower limb stiffness recruitment strategies, which may predispose them to greater sustainment of lower limb injuries, particularly to the anterior cruciate ligament. To positively alter such strategies in women, lower limb muscle st... Read More about Lower limb stiffness: Considerations for female athletes.
