🚨🚨 Interested in ⬆️ mechanical properties of tendons? 🚨🚨

Please see below for a 🧵 on why strain magnitude is an important factor

Proud to be invited to the legendary Narodne Sportove Centrum in Bratislava next month to talk about muscle activation and its role in training, performance & adaptation. Hope to see some of you there 💪⚡️🧠

[Dr. Gerard McMahon @MuscleMechsLab]

@BradSchoenfeld My phd student has just finished a very interesting study in well trained lifters that will add valuable perspective to this.

But yes, I dont think theres anything inherently special about RIs for hypertrophy other than they permit higher volumes per set.

[Dr. Gerard McMahon @MuscleMechsLab]

@JeffNippard tries a 30-day hypertrophy program training arms every day 💪

Will this contribute to the science .... or is it social media entertainment? 👇

[Dr. Gerard McMahon @MuscleMechsLab]

@AlexViKu they arent even trained on the descending limb at all (i.e. little/ no stretch). Then there's multiple studies in quads that show increasing the ROM to even longer lengths (i.e. further descending vs mid descending) doesnt ⬆️ growth

[Dr. Gerard McMahon @MuscleMechsLab]

🔥🔥Chest Hypertrophy Tip 🔥🔥

Load up heavy in the mid-range. Huge torque profile due to length-tension r'ship and mechanical advantage overlap (and bit of passive tension in there also).

#hypertrophy

[Dr. Gerard McMahon @MuscleMechsLab]

@AlexViKu shortened variation isnt a relevant argument to this either. Also, the calves operate on the ascending limb & Herzog, Maganris & Bizet studies show theres minimal growth due to mostly small amounts of passive tension. so while the calves are best trained in dorsiflexion 2/

@lahti_johan im in!

PS that is if you can lend me about £50k? 🤣

[Dr. Gerard McMahon @MuscleMechsLab]

@AlexViKu theyre on the descending limb as I show. Probably the biggest misconception in understanding partials is thinking that you need to take a joint/ muscle to its maximal excursion. That doesn't optimise growth at all

[Dr. Gerard McMahon @MuscleMechsLab]

@AlexViKu growth is dictated by disturbing mechanosensetive receptors in the cell which achieved through active force and passive tension. the ROMs used in research doesnt support extreme stretching of muscles which reduces active tension. The pecs are 'stretched' in this video as 1/

A lot to get through in part 3 – apologies it’s a long one!
Stiffness & RFD, research limitations, representative 'sprinters' in research?.. and where does the increase in stiffness come from?

@LinkedInHelp Can I have a link to your legal and GDPR obligations with handling such data? And how long does your 3rd party partner retain my data and what do they use it for?

Hey @LinkedIn

Why are you trying to coerce me to provide you with a government ID and facial picture to access my account? Ive 2 factor authentication in place yet you've frozen me out and forcing me to comply to access my account. Unfreeze this immediately please

[Dr. Gerard McMahon @MuscleMechsLab]

@LinkedInHelp You are still trying to coerce me into giving you a government ID document. I have 2 step verification on and want to use it for account security purposes, so this is not 'crucial'. Are you telling me you're permanently suspending me unless I provide you with a government ID?

@PauMoreno10 thanks Paul. apologies i keep meaning to turn these on but always forget 🙈

[Dr. Gerard McMahon @MuscleMechsLab]

Does a compliant tendon store ⬆️ energy than a stiffer one? Apparently the S&C profession are getting it wrong by ⬆️ tendon stiffness. Also, apparently compliance leads to quasi-iso contractions
So who actually knows about how tendons store energy & how the MTC functions in 🏃‍♂️?

Chris Beardsley has always been and always will be a social media guru with no skin in the game.

Dr Gerard coming in hottttttttt

[Dr. Gerard McMahon @MuscleMechsLab]

@CoachKenVick I dont think AI would be cruel enough to give itself my face and accent 😂

[Dr. Gerard McMahon @MuscleMechsLab]

@CoachKenVick @lahti_johan @GregLehman thanks for the kind words Ken 🙏

[Dr. Gerard McMahon @MuscleMechsLab]

"Sprinters have the same tendon stiffness or are more compliant than untrained controls?"

Sure - if you cherry-pick weak data and misunderstand tendon biomechanics

The usual awful stuff from Chris Beardsley here.

So this is Part 1 of a 3-part video @lahti_johan @GregLehman
