What recent studies does the speaker mention that support his conclusions?

The speaker references studies showing that moderate joggers have lower mortality rates compared to non-joggers, but those who overdo their running do not see the same benefits. This includes findings from the Copenhagen City Heart Study and others.

What is the term 'pheidippides cardiomyopathy' that the speaker uses?

'Pheidippides cardiomyopathy' is a term coined by the speaker's colleague to describe heart conditions observed in extreme endurance athletes, similar to the findings from the autopsy of Micah True, a legendary ultra-runner.
