Well, yeah. Adipocytes multiply when you get fat. But when you lose weight, they don't apoptose, they just shrink in volume by giving up their lipid stores.

Similar adaptions occur in muscle. The extent of new muscle fiber development (hyperplasia) is debated, so there are multiples factors influencing how muscle retains some memory of past strength ability.

Once you’ve reached a level of physical strength it’s easier to return to that level in the future. This has been a topic of debate in the sports world because past anabolic steroid use could therefore carry benefits into the future long after the athlete has stopped using the steroid. Non-professional athletes shouldn’t get too excited about using steroids, though, because the damage steroids do to the body’s own hormone systems also has lasting effects unless you plan on doing TRT for the rest of your life, which has its own downsides.

For average people this does show the importance of getting at least some exercise when you’re young. It’s much easier to get a little bit fit when you’re young which then makes it easier to stay fit in the future. Never too late too start.

Similar advantage is conveyed to athletes who had elevated (~male) testosterone levels in the past, even if they subsequently take blockers / go on HRT to ~female hormone levels.

Though that also comes with male-pattern skeletal growth. So unless your body still has elevated/male-level T levels, you're carrying around a disproportionately heavy skeleton which negates the advantage. If the net effect were actually an advantage, you'd expect the womens' sports which are allowing trans women to be dominated by them, but they really just aren't.

Additionally, trans women on HRT typically have their T suppressed below standard cis women levels, and thus well below the levels of cis women athletes (the top levels in any sport by definition tending to be outliers in performance).

The male-pattern skeletal growth isn't necessarily a disadvantage. E.g., narrower hips and stronger bones is likely an advantage in running.

My understanding is the opposite. In fact, if it wasn't the case, there is basically no reason to have separate mens and womens fields.

This is anecdotal evidence but I'm a trans woman who transitioned at 30. I ran cross country and track and was the fastest kid at my school in a relatively competitive program. I got depressed after college and gained a bunch of weight and only ran sporadically. I started HRT, I keep my T levels in the lowest range that's healthy for cis women. I got the urge to start exercising again. I now run more than twice as much as before, lost 40 pounds, and do roller derby on top of that. I'm still not as fast as I was when I was mostly sedentary, drinking beers every night in my apartment. I don't know if I'm faster or slower than I would have been if I was a cis woman but I did take a pretty big hit.
