I'll give you the principled answer and the cop-out answer. Here's the principled answer:

That was just the catchy title, similar to peer-reviewed literature reviews published on nih.gov: not necessarily the creme-de-la-creme, just good enough to pass peer review. I real question is whether concern for cartilage erosion is well-founded, and whether or not it outweighs the scientific consensus that running improves bone density of the tibia and fibula. Again, literature had strong evidence for the latter while the former was still a major controversy in kinesiology.

I didn't even touch cardiovascular health, because to be fair we live in a world with bicycles and affordable YMCA lap pools.

Here's the cop-out answer: It's a literature review- the very requirements are merely one step removed from those blog articles Harvard Medicine publishes for mass-consumption. I followed instructions, one of which was to adhere to a maximum of 2 1/2 pages, and I got a Northwestern 95 on the assignment.
