Final answer:

The heart muscle becomes more rigid in young adulthood and elasticity decreases with age. Exercise-induced hypertrophy can lead to a larger heart in athletes.


Explanation:

The heart muscle starts to become more rigid during young adulthood, but this is not noticeable except during times of intense physical activity. As we age, the elasticity of organs, including the heart, decreases gradually starting in the early 20s. In contrast, well-trained athletes may have considerably larger hearts due to exercise-induced hypertrophy.
