Patellar tendon properties with fluctuating menstrual cycle hormones (2010)
Journal Article
Burgess, K., Pearson, S., & Onambele, G. (2010). Patellar tendon properties with fluctuating menstrual cycle hormones. Journal of Strength and Conditioning Research, 24(8), 2088-2095. https://doi.org/10.1519/JSC.0b013e3181aeb12b

Debate continues over whether skeletal muscle performance and injury risk vary over the course of the menstrual cycle. Alterations in tendon properties may play a role in the potential fluctuations of both of these variables. The aim of the current s...

Menstrual cycle variations in oestradiol and progesterone have no impact on in vivo medial gastrocnemius tendon mechanical properties (2009)
Journal Article
Burgess, K., Pearson, S., & Onambélé, G. (2009). Menstrual cycle variations in oestradiol and progesterone have no impact on in vivo medial gastrocnemius tendon mechanical properties. Clinical Biomechanics, 24(6), 504-509. https://doi.org/10.1016/j.clinbiomech.2009.03.011

Background: Tendon tissue contains oestrogen receptors and is therefore likely to be responsive to female sex hormones. Here we examine any effect of levels of female sex hormones associated with the menstrual cycle phase on corresponding tendon mech...

Tendon structural and mechanical properties do not differ between genders in a healthy community-dwelling elderly population (2009)
Journal Article
Burgess, K., Pearson, S., Breen, L., & Onambélé, G. (2009). Tendon structural and mechanical properties do not differ between genders in a healthy community-dwelling elderly population. Journal of Orthopaedic Research, 27(6), 820-825. https://doi.org/10.1002/jor.20811

Elderly women are reportedly at higher risk of falling than their male counterparts. Postural balance is highly associated with fall risk and is also correlated with tendon structural and mechanical properties. Gender differences in tendon properties...

Effect of acute tensile loading on gender-specific tendon structural and mechanical properties (2009)
Journal Article
Burgess, K., Graham-Smith, P., & Pearson, S. (2009). Effect of acute tensile loading on gender-specific tendon structural and mechanical properties. Journal of Orthopaedic Research, 27(4), 510-516. https://doi.org/10.1002/jor.20768

Stretching is commonly used prior to exercise, as it is thought to reduce the risk of injury, and it is also used in the preconditioning of tendon grafts. As tendon properties have been shown to be different between genders, it is proposed that stret...

The applicability of ultrasound imaging in the assessment of dynamic patella tracking: a preliminary investigation (2008)
Journal Article
Herrington, L., & Pearson, S. (2008). The applicability of ultrasound imaging in the assessment of dynamic patella tracking: a preliminary investigation. ˜The œKnee (Amsterdam. Online), 15, 125-127

The purpose of the study was to examine the effect of muscle stimulation of the Vastus Medialis Oblique (VMO) and Vastus Laterialis (VL) muscles on patella position in-vivo assessed by ultrasound scanning. Also to assess the reliability of the techn... Read More about The applicability of ultrasound imaging in the assessment of dynamic patella tracking: a preliminary investigation.

Journal Article
Magee, P., Pearson, S., & Allen, J. (2008). The omega-3 fatty acid, eicosapentaenoic acid (EPA), prevents the damaging effects of tumour necrosis factor (TNF)-alpha during murine skeletal muscle cell differentiation. Lipids in Health and Disease, 7(1), 24. https://doi.org/10.1186/1476-511X-7-24

Background: Eicosapentaenoic acid (EPA) is a -3 polyunsaturated fatty acid with antiinflammatory and anti-cachetic properties that may have potential benefits with regards to skeletal muscle atrophy conditions where inflammation is present. It is al...

Gender-specific in vivo measurement of the structural and mechanical properties of the human patellar tendon (2007)
Journal Article
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

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.
