Question

The overriding problem with both theories of muscle growth, hypertrophy and hyperplasia, is that

Answer 1

Answer:

The Correct answer is A). Neither can be accepted as correct because muscles growth is difficult to study in humans

Explanation: Dont know what the dude above is talking about, but I took the test and got A right. Have an awesome day, and remember to smile. ;)

Answer 2

So I’m a researcher in muscle protein metabolism. I can right out tell you that muscle hypertrophy exists. That’s is muscle fibres increasing in size. However, in humans muscle hyperplasia (the addition of new fibres) has not been demonstrated. It has in birds but not in humans. So neither of those responses are best. Please report back to your teacher and report that question as illogical. 1) muscle growth is not difficult to study in humans. We can use ultra sounds, MRIs to visually see how much muscle has grown and we can calculate muscle protein synthesis rates (how much protein is being synthesized into muscle and thus priming growth). 2) muscle hypertrophy is universally accepted as an occurring phenomenon. Look at body builders for extreme examples, and looks at studies published in the scientific journal called Nature (most reputable scientific journal ). Clearly a bodybuilders muscles are larger compared to the average individual. And we can say for certain it’s due to larger fibre sizes not the addition of fibres. 3) look up Dr. Nicholas Burd, Dr. Dan Moore, Dr. Stuart Phillips. All reputable scientists (dr. Stuart Phillips being the leading expert in muscle protein metabolism). 4) why does the Acceptance from the fitness community even matter when the experts tell you it exists. The Fitness community doesn’t really have a grasp of the molecular part of the muscle to explain or accept hypertrophy as fact. So, I apologize but I have no answer for you because none of those options are correct. Please educate your instructor.
