I just entered myself for a cycling event in the Alpes next year. Trying to set a time for myself I thought I must surely be able to beat the best 70+ entrant but looking at his placing (74/4369 of which one of the contestant i recognise as professional speedskater) , nope must set a different goal…

I would guess these people reflect the small corner of the bell curve. And a large number of us can and will exercise into old age. But to apply to a whole population isn’t realistic.
Perhaps, but I suspect a much higher percentage could get there if they work harder at it (including myself)

True and I think exercise is important, but it is not the only issue. Further more you can do too much.

I have a hunch most people could get a lot more out of fitness if they exercised in a more fast twitch manner. More sprints, jumps. They cannot be replicated by any other exercises and most people don’t do them at all.

I would imagine that kind of exercise would be the most difficult for most of the people I’m seeing that would have trouble with exercise. I’m thinking a walk would be challenging lol.
Not to mention that a fall could be fatal.

The injury risk is higher with suddently starting to sprint training, I would imagine.

The vast majority of people are nowhere close to “doing too much” and even talking about the concern of “doing too much” does them a disservice because it discourages them from doing a lot more, as they are certainly capable of doing.

Probably. Another reason I think our society should emphasize it more, it’s way easier to preserve that functionality than to regain it at 40.

This is a subject i have been fascinated with. Thanks for positing. I too recently turned 50 but am still in the “game” (just) of competitive exercise. I competed elite level at duathlon and triathlon in my mid 20s and still race now pretty competetively and have been lucky enough to win 9 World Duathlon AG titles and have every intention of continuing if i am able to. I have noticed my V02 has dropped a little since 40 but my threshold much less. As a software engineer i like measuring everything with training and health so have my training logs going back to the mid 90s. My FTP on the bike is within 20watts of my best in my early 30s and my half marathon times are around 1-2 minutes slower than my peak (the erosion is somewhat halted by the carbon plate shoes). Even though my data still looks decent now i do absolutely think there has been age related decline which i have largely offset by smarter training, technology (shoes), better nutrtion, better sleep and less alcohol
etc etc So for me personally i am closer to the genetic ceiling now for my age than i was in my supposed peak (mid 20s). The biggest challenge though is susceptibility to injuries. I have mutliple tendon tears which have been tricky to overcome; luckily we live in an era of amazing regenerative medicine and with procedures like PRP i have largely overcome all of them. Feel very fortunate. As a relatively new Rapa user curious if any performance biomarkers have improved for athletes?

i would agree. Peter Attia recently discussed this and his view is there really isnt any upper limit to the benefits of aerobic exercise…although obv there are dimishing returns once you reach a certain level. The only caveat to this in my view is that their is likely a sweetspot of volume/intensity for certain sports for each of us since the risk of orthopedic injuries offsets the benefits.

Supposedly drop in VO2MAX is mainly due to a drop in maximum heart rate. In mice rapamycin can restore cells from the sino-atrial node but I haven’t tried any maximum efforts since starting rapamycin to see if I can beat my maximum heart rate. In mice rapamycin can also increase stroke volume which can compensate a bit for the loss of frequency
