how can your muscle fibre makeup be genetic if specific training can and does change it?
 
Sounds like the method of testing was incorrect.

At first you'd think so, I thought this also especially when he stated two months later in a weider mag; "of course i fudged the tests "

If you put in a good isometric effort at force production at 8 different points of the ROM, for example, you will produce a particular shaped strength curve, plotted on a graph.

The next day if you put in that same quality of effort, you will see the exact same shape. Now, you may not reach all the same numbers (maybe you can produce 10 pounds more torque at one point the second day than you did the first day)... but the overall shape is pretty much the same.


If you were to fake it, you would have to know how much to fake it at every point on the graph in order to produce the same 'off' strength curve from one day to the next.


In Hatfield's case, he produced the SAME shaped strength curve, and the force production at each point in each curve were very much spot on.

Yes, the guy squatted over 500kg's, but he had a super wide stance, had a lot of lean over, and used a lot of glutes to get that load up.

I think that if he had of done specific higher rep work from time to time he could of squatted more? maybe not I'm not sure as his squatting style was more glute ham dominant anyway, I have really no idea.

what it does does mean though is fibre type ratios should be factored in and because it is difficult to near impossible to determine the % we must use a combination of rep numbers .
 
Genetics mean I have thin wimpy facial hair, even still - I can choose to grow the seedy face pubes if I want to

I think the reality of that statement means that we all have a genetic potential/ceiling but most if not all of us exist way below that if we are talking about hypertrophy and strength. That doesn't stop us from trying to get there though (with or without chemical assistance).
 
genetic potential? means nothing to me, I just try activities I like, encourage others to improve, and what will be, will be.

why hell yeah, it's not like we have any world record beating aspirations around here. :D

I do like pushing my body (and mind) to the limit though, doing the things I enjoy.
 
your muscsle fibres will be from environment (training) and adaptation of what you've been doing the last 10yrs, not what you were born with. its not written in stone, it changes with exposures to certain types of training. is that our genetics changing? epigenetics maybe.

This is basic, so that it can be understood;
We are born with a set ratio (cannot be changed) or percentage of fast and slow twitch fibers in a particular muscle, out of the thousands of muscles supporting the skeleton and circulation the % of fast and slow twitch fibers will differ not only from one person to the next but from one muscle to the next of an individual.

The reality is, genetics play a huge role, and it is not just one thing, others factor include muscle belly size;
The calf muscles contribute little or nothing to either running or jumping, serve primarily as shock absorbers; you
cannot jump high enough to even get your feet off the floor while using only your calf muscles.
When running you first throw your lower leg out in front of you, using the quadriceps muscles (the front of the thighs) and the hip flexors, and
the calf muscles contribute absolutely nothing to that movement.
Then, when the involved foot is planted on the ground in front of you, the body is pulled forward towards the planted foot, that part of the movement being performed
primarily by the muscles of the buttocks, again with no meaningful contribution of the calf muscles.
Thus an increase in size, and the weight, of the calf muscles would make it harder for you to throw the lower leg as far
or as fast as you could with smaller calf muscles. So you would be slower rather than faster.

Bullshit. Sure you can change it slightly with training but you can't beat your genetics. It's why no white guys are winning the 100m

Epigenetics is genetics. Lol.

really? the foot does nothing?

Well maybe you need to listen to Nick Curson on joe rogans podcast, his str and conditioning is based on russian performance (yes scientific studies), and one important part was how much the foot plays in everything, for eg he said olympic weighlifters use more force through of the foot than any other muscle. (edit, their feet nearly leave the ground, on the ball of the foot not flat footed)

i think your talking shit about jumping has nothing to do with the foot, if your flat footed you won't jump, the idea is to spring from the front of your foot, then lift your knees, not the knee makes you jump...

and like manny pac, huge calves, VERY good footwork, very fast, always on the ball of the foot not the heels. foot strenght is HUGE in performance!

But the Soleus is primarily utilised in plantar flexion which is an integral part of running and juping...
 
For BBing, I always thought of genetic potential in a simpler way.
As an example take a look at the biceps of two separate kunce:

Kunce A was born with 200k muscle fibres in his biceps
Kunce B was born with 400k muscle fibres in his biceps
BBing can only increase the size of fibres we already have, cannot increase the qty of them.
So even in the unlikely event of kunce A and Kunce B grow the size of their fibres at the same rate, which kunce will end end up with the bigger gunz?
The kunce that increased 400k fibres by 50% or the kunce that increased 200k fibres by 50%?

Another Q, why do we have extremely hot and and extremely ugly chicks?
Beauty creams? Doubt it!
It's the genes Kunce.
