Question

the overriding problem with both theories of muscle growth, hypertrophy and hyperplasia, is that ______. a. neither can be accepted as correct because muscles growth is difficult to study in humans b. neither one is theoretically possible c. neither has been studied by reputable scientists d. neither has been accepted by member of the fitness community please select the best answer from the choices provided.

Explanation:

To solve this, we analyze each option:

• Option B: Both hypertrophy (muscle cell enlargement) and hyperplasia (muscle cell number increase) have theoretical plausibility in muscle growth, so B is wrong.
• Option C: Reputable scientists have studied both theories, so C is incorrect.
• Option D: The fitness community does accept concepts related to hypertrophy (e.g., muscle growth from exercise), so D is wrong.
• Option A: Studying muscle growth in humans is difficult (ethical, practical issues in controlled studies), making it hard to fully validate either theory as correct.

Answer:

A. neither can be accepted as correct because muscles growth is difficult to study in humans
