Question

Is a post-exercise snack shown to increase muscle glycogen stores and protein synthesis?

a) True

b) False

Answer 1

A post-exercise snack is indeed effective for increasing muscle glycogen stores and protein synthesis, contributing to muscle repair and growth post-training. It is essential for recovery and enhances muscle adaptation to training.

Step-by-step explanation:

The statement that a post-exercise snack is shown to increase muscle glycogen stores and protein synthesis is true. In the absorptive state after exercise, muscle cells convert excess glucose to glycogen for storage, and amino acids are used to synthesize proteins like actin and myosin, contributing to the repair and growth of muscle fibers. This process is facilitated by insulin, which is more active during this state, promoting the uptake of glucose and amino acids into the muscle cells. Moreover, during the postabsorptive state, the body must rely on stored glycogen for energy.

Eating a combination of carbohydrates and proteins after exercise can replenish these stores more quickly and effectively than fasting or consuming fat predominately. The glucose from carbohydrates aids in replenishing glycogen stores, while the amino acids from protein sources are essential for repairing and building muscle tissue. Therefore, a balanced post-exercise nutritional intake can significantly enhance recovery and muscle adaptation to training.

Answer 2

A post-exercise snack is true to increase muscle glycogen stores and protein synthesis, as it helps replenish glycogen levels and supports the synthesis of muscle proteins required for muscle recovery.

Step-by-step explanation:

The statement that a post-exercise snack is shown to increase muscle glycogen stores and protein synthesis is true. After exercise, the body enters an absorptive state where muscle cells convert excess glucose to glycogen for storage, using glucose-6-phosphate as an intermediary. This process is crucial for replenishing the muscle glycogen that was depleted during exercise. Moreover, amino acids provided by a snack can be used to synthesize proteins like actin and myosin, which are necessary for rebuilding muscle fibers and enhancing muscle protein synthesis.

In summary, a post-exercise snack that includes a balanced proportion of proteins and carbohydrates can support the metabolic pathways involved in restoring muscle glycogen levels and accelerating recovery through increased protein synthesis.
