>Peek and her team found that muscle repair after injury was greater when mice were active or awake compared to when they were inactive or resting. This isn't the result I was expecting. That's very counterintuitive

If you consider it fully, you may change your mind. The bodies natural cycle in sleep is not intended for muscle repair. So it makes sense that it does not suddenly become the prime concern during sleep. Muscles get better oxygenation and fluid exchange when they are being used, pumped, and this helps remove lactic acid and deliver nutrients.the same can be said of the lymphatic system which you can look into. Looking at top teir athletes, cool-down excersizes are standard practice after intense workouts... All of these lead to this conclusion, though in hindsight, of course, it's easier to stitch together

  > The bodies natural cycle in sleep is not intended for muscle repair You say that, but there's a lot of evidence showing that poor sleep is correlated with poor recovery from training. Top tier athletes also carefully manage their sleep schedules.

    Read the whole comment, I think that's addressed. The sleep cycle is a regular maintenance routine. The whole body functions more efficiently with proper sleep. Sleep as a bodily function is not intended to repair serious injury. Otherwise, when people became injured they would fall asleep, except we don't fall asleep when injured. We become hyper vigilant and produce adrenaline. So certainly there's correlation, but the broader picture 'makes sense' and is not counterintuitive

Yeah this is really interesting to me. I work out 4+ times per week, and I've noticed that when I go at it harder than usual, my body basically forces me to sleep twice per day until it's repaired itself, and when I sleep it's usually unintentionally 4-5 hours at a time. I'll wake up and can't go back to sleep, so I get up and do things for a few hours until it's time to sleep for another 4-5 hours. But when I take it easy with my workouts, I'll sleep a solid 7-9 hours uninterrupted. I wonder if my body does this because it needs nutrition and bloodflow to heal and doesn't want to wait for it.
