The fact that all this knowledge is here for free is absolutely crazy

Great video! You should make one covering the topic of prevention or the rehab of a pulled muscle, because it's a common things among athletes.

Wow this was amazing John is a jumping genius

Such an insightful video. Thank you so much for this ❤. I have this question that I really want to be answered. What should I do or avoid doing in order to get that "athlete-like" lengthening of tendons and shortening of muscles?

Great job with this video!

But I knew this concept after 1 year of training. The book practise& science of strength training also had this topic. This concept also explains why max strength doesn't help much in athletics. We need a fast RFD. Further it also makes a difference how stiff/compliant the tendon is. Stiffer is not always better. Joint ROM and external load are factors. I think John knows all this. If he shares it too?

Tendon jump program needed

Amazing video

W vid also can you please post like a good finishing workout(basketball wise)?

Love these videos

This is the best video on the internet

Can we get a video on how you plan training in relation to the SSC progression if slow CON work is at the end of the continuum? Gracias

For the SSC/plyos/tendos, cld u give examples for the ecc, iso and conc? You mentioned ecc was fast stuff, pogo hops and sprints? Then would conc be stuff like broad jumps/bounding? What would isos be?(isos in this case sounds weird)

Thx bro been you help me from barely being able to touch backboard to dunking smaller balls in 8th grade also when did you get your first dunk?

So to build the muscle the eccentric moment is better? And the concentric is better for tendons? Pls tell If I’m right, I’m kinda confused, so to jump higher should I perform the eccentric slow Tempo? And should the concentric be perform fast tempo?

How does the gastroc & soleus remain the same length while the achilles lengthens during ankle dorsiflexion?

Thank you, it was very understandable! Now I just need to fix my knee pain :D

When the tendon lengthens, aren't the golgi tendons sending inhibitory signal to the muscle, essentially making it relaxed?

Do a hip pain video please

What’s your long and high jump? I think you should make a video on that because you’ve done volleyball

how do you have a plyo that has a slow concentric contraction. most plyos are hi intensity so i’m trying to figure that out

Tendon: not written in blue Isaiah:🫨

In the long term should i train for weigths room or SSC/Plyos?

Good

Does the whole concept of concetric contractions in good athletes imply that getting stronger eccentrically is important because it allows you to get to a concentric contraction as quickly as possible, so that the muscle can pull on the tendon more and for a longer period of time (within the time constraints)?

Vertical jump

47:08 I am Italian and I don't understand English well. Can anyone explain to me what this practically means in terms of exercises?

So youre saying, in the beginning of the year you train low intenstiy, so that means you focus primarely on concentric weight lifting movements and on escentric plio movements. What are examples for these movements, death drops combined with cleans(during the beginning of the year)? And do you mean that this is the most effective way to train through out the year?

Please explain these with exercise as example. Then these will very easy to understand.

Adding time stamps would be nice

is this even possible that tendon lengthens while muscle stays neutral? So at what point muscle starts shortening?

So how can we improve our muscles to pull the tendons even more?

lunchtime learning every day letsgoooooo THP new videos every day letsgoooooo like and subscribe letsgooooo

Just saved like 10k on some exercise science courses

how do we train our muscle to not lengthen or even contract?

On the force-velocity curve why is lowering a heavy weight eccentrically considered high force? If you lower the weight very quickly aren't you reducing the amount of force you are applying to it?

can u just increase my vert to 52 inch bro

33:28 Isaiah is asking the real question here this is exactly where the whole theory is flawed. According to the theory,tendons are supposed to be elastic to some degree, well I'm sure they are since they're still tissues.BUT if they are as elastic, why wouldn't be stretched in an isometric contraction?? every single time you lift weights, imagine a rubber band attached between your bone and mucles, this rubber band will be stretched and lengthened, the heavier the weight the longer it should be stretched! But do you feel that your bicep tendon stretching everytime you do curl？Probably not, because tendons are predominatly rigid!

isaiah this beard looks way better on you!

So it is important to develop an eccentricity so the negative controlled and then still aim at the concentric always as fast as possible, but then also another cycle that towards the speed with both eccentricity and concentric at the maximum speeds and this can be seen with the plyo ??

Is this concentric muscle contraction linked to the precontraction sometimes mentioned before the collision of a plyometric action? If so is it possible to consciously make it happen? or is it too fast to do so?

Yo isaiah is 23 inch very good to 13 years old and hight 5'5

WHERE IS MY GUY AUSTIN?

I disagree

isn't is whole therry long debunked?.. imagine actually replacing achilles with a spring, the moment your calf muscles try to pull, instead of conducting the energy immediately to your feet, your spring-tendon will slowly be expanded from your muscle side and slowly try to shrink back pulling your heels ,making the whole contraction process much slower. Imagine replacing your bike chain with elastic bands, that's pretty much the same thing here. You will find it really hard to start quickly. Kangeroos are built extremly differently from humans,as you can see they have much longer feet and when they jump they lean their bodies forward and therefore create an angle that allows them to use their long feet as running blades,which is actually energetic efficient. so bascially speaking, if the structure that directly apply the force like your foot arch is elastic,it's good. but if the structure that conducts the force, like your achilles is elastic, it might actually do the opposite thing.

Lecture us lecture us yo

No idea what this bloke is talking about
