On this episode I focus on a new study from my PhD student Eman Merza. It is a cross-over randomised trial testing the effect of high and low contraction time and high and low intensity isometric contractions on acute changes to tendon volume and stiffness. Some very interesting potential insights for tendon adaptation. Good work, Eman!
Hope you enjoy.

Exciting new insights into tendon adaptation with load

This podcast will delve deep into the best and most clinically relevant new studies on tendinopathy. The focus is what questions the researchers tried to answer and why, how they did it, what they found, and very importantly, the so what factor. That is, how can it be applied to the clinic and to individual tendinopathy patients.

This week I talk about a feasibility cohort study which sought to determine whether a larger cohort study addressing this question would be feasible. Listen to hear some interesting preliminary findings.

Do psychological, cognitive, and contextual factors influence rehab outcomes in Achilles tendinopathy?

We have known for a while that type of exercise intervention (e.g. intensity, frequency, etc) does not seem to influence self-reported outcomes such as pain. Maybe all the benefits from exercise are explained by non-specific effects, or maybe exercise has benefits that do not depend on the type of exercise.
In this episode, I discuss 3 studies that look into (at least partly) other benefits that we may see at the level of the muscle and tendon from higher-load exercise interventions.

Does high load and high strain exercise have any benefit for Achilles tendinopathy?

This week, I had an engaging conversation with Anthony Nasser, an up-and-coming researcher on tendinopathy who recently completed his PhD on proximal hamstring tendinopathy. Our discussion covered the reasons for the lack of research attention towards this condition, the current state of evidence, and insights from his doctoral studies. You can find the full conversation here.

Proximal Hamstring Tendinopathy - the forgotten tendinopathy

Palpation can be useful for the diagnosis and assessment of tendinopathy, but there are limits. This is because non-painful tendons can be tender, and tenderness in painful tendons seems to be very slow to get better.

How useful is palpation for diagnosis and assessment?

Interesting perspective paper from Arampatzis et al talking about how we should consider tuning of muscle tendon unit in terms of muscle strength and tendon stiffness when considering training for specific groups.  See omnystudio.com/listener for privacy information.
