Onambele, G., Burgess, K., & Pearson, S. (2007). Gender-specific in vivo measurement of the structural and mechanical properties of the human patellar tendon. Journal of Orthopaedic Research, 25(12), 1635-1642. https://doi.org/10.1002/jor.20404

Human patellar tendon stress (σ), strain (ε), stiffness (K), and tensile or Young's modulus (E), are determined in vivo through voluntary isometric contractions monitored with B-mode ultrasonography. The limitations in previous studies are: (1) they... Read More about Gender-specific in vivo measurement of the structural and mechanical properties of the human patellar tendon.

Plyometric vs. isometric training influences on tendon properties and muscle output (2007)
Journal Article
Burgess, K., Connick, M., Graham-Smith, P., & Pearson, S. (2007). Plyometric vs. isometric training influences on tendon properties and muscle output. Journal of Strength and Conditioning Research, 21(3), 986-989

The purpose of this study was to concurrently determine the effect that plyometric and isometric training has on tendon stiffness (K) and muscle output characteristics to compare any subsequent changes. Thirteen men trained the lower limbs either ply... Read More about Plyometric vs. isometric training influences on tendon properties and muscle output.

Creep and the in vivo assessment of human patellar tendon mechanical properties (2007)
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.

Time-of-day effect on patella tendon stiffness alters vastus lateralis fascicle length but not the quadriceps force-angle relationship (2007)
Journal Article
Onambele-Pearson, G., & Pearson, S. (2007). Time-of-day effect on patella tendon stiffness alters vastus lateralis fascicle length but not the quadriceps force-angle relationship. Journal of Biomechanics, 40(5), 1031-1037. https://doi.org/10.1016/j.jbiomech.2006.04.001

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...
