Answer:
e) the most effective, safe way for athletes to add muscle tissue.
Explanation:
The repetitive work of muscles, especially in weight training, is the most effective method to build muscle. This occurs due to the hypertrophy effect that these exercises generate on muscle tissue, allowing it to grow stronger, increasing both resistance and strength of the athlete.
An increase in protein intake, combined with this type of exercise can boost muscle growth. However, the amount of protein ingested must be adapted for each individual, preferably prescribed by a nutritionist, and not simply tripled, as it says in alternative B.
As for overtraining (mentioned in alternative C), it only occurs due to excessive exercise, beyond what the body can support, whether due to extreme intensity or volume. Exercising with repetitive demands, in a way adapted to the athlete, can even help to increase resistance against overtraining.
Therefore, the alternative that best answers the question is "E"
