We are a commune of inquiring, skeptical, politically centrist, capitalist, anglophile, traditionalist New England Yankee humans, humanoids, and animals with many interests beyond and above politics. Each of us has had a high-school education (or GED), but all had ADD so didn't pay attention very well, especially the dogs. Each one of us does "try my best to be just like I am," and none of us enjoys working for others, including for Maggie, from whom we receive neither a nickel nor a dime. Freedom from nags, cranks, government, do-gooders, control-freaks and idiots is all that we ask for.
Those studies mostly looked at one hour bouts of aerobic exercise (according to the linked article). I'd like to know how my brain responded to the 295 pound squats I did for three sets of ten on Monday! I know how my heart, lungs, and legs responded, that's for sure. :-)
If done right "Long Slow Cardio" stresses certain subsystems. If you're at or near your lactate threshold (i.e. near the top of "Zone Two") and you hang out there for 45 minutes or an hour, you wind up stressing your energy system and training your mitrochondria to use both glucose and fatty acids (not ketones) as an energy substrate.
This will aslo increase the GLUT-4 and/or GLUT-1 transporters on your muscle cell walls.
Doing HIIT, calesthenics and resistance training also does things, and these things are also important, but don''t discount the effects of 3 or 4 long, slow cardio sessions each week.

I am so grateful for your article.Thanks Again. Will read on
I find the same thing is true of physical labor. Not necessarily hard or excessively physical work but simply working at something with a tangible result. Like digging a garden or painting a house or raking leaves, etc. It may be partly physical as in detectable changes in your body (i.e glucose, fatty acids, etc.) and it is also likely in part psychological in the joy and satisfaction of seeing a job well done.
I remember that my grandmother, who lived with us my entire childhood, took great pleasure in baking and did so almost everyday. Making bread consumed a few hours, making a pie took almost as long, almost any baking done from scratch was time consuming but produced beautiful results. I think it was her psychological "high" and gave her pleasure everyday. I noticed too that she even enjoyed the cleanup process and even the presentation of the finished pastry. Interestingly I don't remember her ever eating any of the goodies she cooked except for bread.
