Let's evaluate the statements regarding the body's use of protein after exercise:
-
After strenuous exercise, muscles repair themselves by using available amino acids to synthesize new proteins.
- TRUE: This statement is correct. After exercise, the body utilizes amino acids from protein sources to repair and rebuild muscle tissue.
-
After engaging in intense physical activity, athletes may be able to enhance protein synthesis in their muscles by eating protein-rich foods.
- TRUE: This statement is also correct. Consuming protein-rich foods after intense physical activity can promote muscle protein synthesis and recovery.
-
When athletes consume excess protein from foods and supplements and the body does not need the extra energy, the amino acids in the proteins will be used for building or repairing muscles.
- FALSE: While amino acids can be used for muscle repair, excess protein that is not needed for immediate energy or repair can be converted to glucose or fat and used for energy or stored, rather than being exclusively used for muscle repair.
-
The carbohydrate-to-protein ratio in low-fat chocolate milk promotes energy and muscle recovery and protein balance after exercise.
- TRUE: This statement is correct. The carbohydrate-to-protein ratio in low-fat chocolate milk (typically around 3:1) is effective for replenishing glycogen stores and aiding muscle recovery after exercise.
Based on the evaluation, the true statements are:
- After strenuous exercise, muscles repair themselves by using available amino acids to synthesize new proteins.
- After engaging in intense physical activity, athletes may be able to enhance protein synthesis in their muscles by eating protein-rich foods.
- The carbohydrate-to-protein ratio in low-fat chocolate milk promotes energy and muscle recovery and protein balance after exercise.
