Yes it is, because science has no definitive answer. If you find something that works well, you are going to use it. It is common sense.
Evidence for claims can be based on controlled scientific studies subject to peer review or can be based on anecdotal evidence by users - i.e. users' subjective " opinions ". I put more faith on scientific studies and even more on the placebo effect.
Science takes subjective " opinions " out of the equation and looks at hard objective data upon which to draw conclusions and formulate theories.
As for the notion of " find something that works ". Believe it or not, some gym rats out there still think " spot reducing " works. They actually think high reps leads to muscle defintion - i.e doing dozens and dozens and dozens of bicep curls will lead to defined biceps. Despite the fact science has proven this whole notion to be false, they still THINK high reps "
works well ". They see ( or
think they see ) their arms getting defined and will turn to their own subjective data ( their opinion ) upon which to draw conclusions .......simply confirming their pre-conceived notion that high reps leads to muscle defintion. This is the fallacy of confirmation bias IMO. In the same way as people who scarf down huge amounts of protein over the present .8 guideline simply because they THINK tons of protein means more muscle....i.e if .8 is good then 2 must be much better. It isn't based on the generally accepted protocols / guidelines supported by research....but, it is based on a pre-conceived unsubstantated notion...and number ( i.e 2 ) picked out of the air based on subjective judgements...not science.
You can only know what the upper intake is for the average person, since that is who almost all studies are done on. Why? Because athletic people do their own research in the field and get real results. Sometimes it contradicts what science says, and that is fine.
No, the studies / recommendations are for endurance and strength athletes ( looking to add muscle ) as well as " the average person ". That is how the upper level - the 0.8 guideline - came about.
Bodybuilders are not the " average person ". Tell me, if I told you they studied the protien intake of hard-core bodybuilders and found that results from bodybuilders was part of the research that prompted them to still form the 0.8 guideline, would you have any more faith in the guideline's broad application ? Because, my recollection is, researchers Mark Tarnopolsky and Peter Lemon specifically looked at bodybuilders with respect to this protein issue and developing the guideline as to what is an " opitmal " intake amount.
The flaw with science is that there are no absolutes,
Correct, and within this context, science is trying to determine the " optimal " protein intake level with respect to adding muscle - not the absolute level.
there are always exceptions to the rule, anomalies in the research that can't be explained.
There is no anomoly in the research IMO. In fact, I suspect one of the the reason much of the research was done, in part, was due to the fact so many people believed tons of protein is needed to build bigger muscles. So, they have studied whether tons of protien has any significant impact on building muscle ( i.e well beyond 1 gram per pound of bodyweight ) - and - in doing so, have found no evidence that it does. That is my point - this whole issue of protien intake levels ( from very low to very high ) has been studied to death.
Take Lance Armstrong, He had a team of people doing research "on him" all the time to find out what would work specifically "for him." Many of the training methods that he used will not work for other people. Many of them will work for other people. There is no way to know without trying. The difference is the results of the testing were specific to one person.
So, for example, even though science has theorized that EPOC may be the reason for enhanced fat loss from a training method like HIIT - HIIT may not work at all for Lance for fat loss ? The fundamental assumptions of science supporting EPOC or HIIT may not apply to him ? And, they may also not apply to 50% , 75% of the target population ? You're saying we
can't ever make generalizations about
any conclusions derived from studies because everyone is different ? If that is the case, what is the point of research if we can't make inferences about findings ?
Here is another example. Lets say YOU started getting 2g of protein per lb of body-weight. What if you got the best results you have ever had under those circumstances? The only way to find out is to try.
Its anecdotal evidence only - it proves nothing - that is my point. It is the same evidence that companies who hawk scam muscle-building supplements use....these companies claim their stuff works.......not because of FDA validation or evidence found in peer reviewed journals........but rather, based on questionable " in house " studies or anecdotal evidence.
If the theory is that ( generally speaking ) 2 grams of protein per body weight results in more muscle than 1 gram of protein per body - that specific level likely has already been examined by a study to attempt to validate the claim. I would have to go back and re-visit the exact studies, but I suspect doses close to 2 grams per pound were among those levels evaluated. We know that excess protein simply gets stored as fat or discarded by the body and we know that mucle gains are easy to measure. And so far, given we know these things can be tested for, (for non-steroid trainees at least ) ...there is no evidence to suggest 2 grams of protein per body weight results in more significant muscle than 1 gram of protein per pound of bodyweight.
Science in the fitness field will always be guidelines. There are too many differences between individuals to know "for sure" that a certain protein intake is proper.
Correct. The " guideline " is that there is no need to consume more than 1 gram of protein per pound of bodyweight. There is no evidence to suggest any significant added benefit. As for " differences between individuals " , anytime recommendations are made by the Centers for Disease Control and Prevention, The American College of Sports Medicine, The American Council on Exercise, The American Heart Association, The American Dietetic Association etc. etc. they are still made with full acknowledgement that differences exist among the population or they specify populations.
Even then, the sliding filament theory is a theory, Most people think that there are only Type I and Type II muscle fibers, this is only a theory. People think that you can't increase the number of muscle fibers, again, only a theory. Just like the .8 grams of protein suggestion is based upon theory.
Correct. A theory supported by rigorous study and supported by objective evidence.
Set and rep protocols can only be validated on an individual basis. Yes we know that heavier weight and less reps is more nervous system based and more reps and higher weight are more muscular system based. But, the application of that will be different on an individual basis, it will also be different at different times in an individuals exercise career.
Correct. We know that guideline because SCIENCE has established it as a valid one - you just made my point . Thanks.
Also, suggesting the " application of that will be different on an individual basis " isn't a sufficient basis by which to invalidate a guideline.
We are not taking into account the speed of these lifts. Different people will have different results training at different speeds. There will never be and absolute answer.
That is my point. There is not an absolute answer. If taking in more protein the "the research says you should" gets better results than following the research, you will continue to take in higher amounts of protein.
Correct..the guidelines only suggest what is " optimal " protien intakes for added muscle mass - it isn't about absolute intake levels.
As for " higher amounts " - you don't know if the protien is the reason for the results you think you're getting - that is my point. Claiming something is " so " without being able to explain " why " it is so is simply leaning more towards correlation than direct causation. So, if a trainer's clients say ( or so they claim ) they take 2 grams of protien and they put on muscle...perhaps they would have put on about the same muscle with only 1.0 grams or .8 grams.
(I am by no means telling anyone to ignore scientific research. It has been, and will continue to be a great thing that will help us get better. I just want to be clear that science is not currently producing absolute answers.
True, science can determine what is " optimal " - not absolute.
So, in terms of " opitmal " can I assume you also question HIIT, rep speed, insulin response, pre, during & post-workout nutrition etc. etc. theories, various American Council on Exercise positions etc. etc. to the same extent you have reservations - which it is clear you do - about max protien intake guidelines ? Because the same stringent generic scientific protocols are used to study and develop theories in these areas as they are for research into protein consumption.
And on the issue of " absolutes " .....do you think science has the ability to delclare a claim a " myth " or not - can science make
absolute claims something is a " myth " ?
But, when all is said and done, you THINK that more than 1 gram of protien may be valid in terms of being " optimum" - and that, in the end ( whether it is supported by science or not ) is all that counts. You simply THINK it may be valid. So, stroutman81 is right ...some of us seem to disagree as to whether the jury is still out on this ' max protein needed ' issue or not....you do, I don't happen to think it is.
Let's just agree to disagree on this topic, leave it at that, and move on .
