Higher risk of tendon injuries right now with many people running a lot more than normal. Same for team sports who may have a very short and accelerated pre-season when games resume having not been able to train at regular intensity. Tendons don't like holidays or big surprises!

(1/2) Achilles tendon structure & the degree of twisting of the sub fascicles it receives from the 3 calf muscles, varies from person to person. This has an impact on muscle loading, the degree of sliding between tendon fascicles & how stress is distributed throughout the tendon

Hate the term 'punching above our weight' when it comes to population and international success. Are the Borlées and Ingebrigtsens punching above their weight? Culture, environment and application of high performance standards on a daily basis. Bigger impact than population

Extra cushioning in shoes do not reduce impact when running. What the runner does in the shoe matters, as they adjust their mechanics in cushioned shoes resulting in greater impact loading. Wrong to assume ⬆️cushioning = ⬇️ injury risk

Active cool-downs not as beneficial as we were traditionally led to believe. No impact on muscle soreness & can interfere with glycogen resynthesis. Some positive benefits. Perhaps its inclusion depends on what system needs recovery & adaptive response

A 🧵on where my head is with Achilles tendon (AT) ruptures.
A rupture likely occurs in a tendon with ⬇️tissue quality. Most often in a region of the AT that is remodelling as it tries to adapt to ⬆️activity levels. A silent tendinopathy, perhaps?

Runners who rearfoot strike have more fascicle length changes in their calf muscles during ground contact, while runners who forefoot strike produce more force in the calf muscles - either of which increase energy cost. So no difference in economy between strike patterns

Interesting new proposal on how to individualise an exercise program to focus more on either muscle or tendon adaptations.
Under max voluntary contraction, if max tendon strain is <4.5% - focus on muscle; if >10% - focus on tendon stiffness

Evidence to date suggests that the timing of hamstring injuries occur during the late swing phase of high speed running - where the muscles are most activated and the muscle-tendon units rapidly lengthen under highest forces.

1 leg bodyweight heel raises (or 200 heel drops per day) is not enough to prepare the Achilles for the demands of running after injury. If you can handle 1 leg forward hops you can handle running!
#WatchThisSpace
#SSCAchilles
Walking puts a 3.3-bodyweight load on your Achilles; running puts 5.2 BWs. What rehab exercises progress you to that point?
sitting heel raise: 0.5
1-leg standing heel raise: 3.0
2-leg hop: 4.8
1-leg forward hop: 7.3

How often do we hear some coaches who regard fast twitch athletes as ‘lazy’ and ‘don’t train hard enough’? They are just wired differently and need to be managed more carefully
Muscle fiber type is associated with overreaching response to overload training
