Question

Which of the following explains why exogenous amino acids are required following high-intensity activities and strength training?

a) To meet the basic metabolic needs of muscle tissue.
b) To repair muscle damage from high-intensity exercise.
c) To build new muscle tissue.
d) All of these are correct.

Answer 1

Exogenous amino acids are required following high-intensity activities and strength training to meet metabolic needs, repair muscle damage, and build new muscle tissue.

Step-by-step explanation:

The correct answer is d) All of these are correct.

Following high-intensity activities and strength training, exogenous amino acids are required for multiple reasons:

1. To meet the basic metabolic needs of muscle tissue: Amino acids are used for the synthesis of tissue protein, enzymes, hormones, and other proteins needed for muscle repair and function.
2. To repair muscle damage from high-intensity exercise: Amino acids, especially branched-chain amino acids (BCAAs), have an anabolic/anti-catabolic effect on muscle, aiding in the repair and recovery process.
3. To build new muscle tissue: Amino acids provide the building blocks for protein synthesis, which is necessary for the growth and development of new muscle tissue.

Therefore, all of these explanations are correct.
