Answer:
False.
Step-by-step explanation:
This statement is not completely true, because walking is a low impact exercise, but running is not.
We can define joints as the connection between separated skeleton parts, making easier this interaction. When we walk this interaction between two parts has low intensity, causing not damage to the joint. On the other hand, running can be harmful, because the intensity is higher, and also the impact higher when practicing it.
However, this high impact is dangerous depending on other conditions like weight and physical posture while doing it. If a person is not overweighted and know how to maintain a healthy posture, this activity won't represent any danger.
