Performance Medicine

Can anyone point me to more information on this medical path? I've been doing a ton of research and from my understanding it's really just a mix of a few different specialties. From the link below, "It is a new and innovative medical specialty that merges the goals of internal medicine, anti-ageing medicine, sports medicine and preventative health care." Is this something that is gaining traction? Would an IM residency with sports medicine fellowship be the way to go? Thanks in... Performance Medicine
