It seemed counterintuitive at the time but back when I could run an ultra marathon, my coach would have me do an easy 3 mile run the day after my longest and most difficult runs (5 hours or more in some cases).

For the first mile I could barely move - then I loosened up and eventually finished up at a slow steady pace. This all accelerated my recovery.

For sure, blood flow and low intensity work is great for reocvery. That's partly why things like saunas work for recovery, many pasive modalities increase blood flow. The farce is in attributing this to "clearing lactic acid", which is still often said by sports coaches for some reason. Lactic acid / lactate and hydrogen ion accumulation are cleared quickly, otherwise you'd be in acidosis for hours or days. The body regulates PH really well. Type 1 muscle fibers use lactate for energy in particular, that includes skeletal muscle but also the heart which is mostly type 1 fibers.

I even do similar things with novice clients, we do low intensity and moderate volume at first, but i'll advise them to train through soreness but keep the itnensity low. More often than not, they feel better immediately afterward and even the next day than if they didn't do it.

RICE was a lie!

Indeed. A lot of people are still using it though. It makes sense that you wouldn't want to diminish the bodies natural healing response, who woulda guessed.

“Lactic acid is usually thrown around by sports coaches as a cause of soreness, but it doesn’t contribute directly to DOMS since lactate is cleared within minutes after an exercise is completed.” Thank you for saying this.

They really beat the dead horse about this in my grad program lol.

I can remember working through the process of glycolysis in undergrad and thinking, “surely this lactate can’t be what people refer to as lactic acid and attribute muscle fatigue, failure, and eventually soreness.” Further work revealed the truth of lactate’s (humans don’t make lactic acid) alkalinizing effect with other factors contributing to acidification. That was over 10 years ago.

I'll use the term every now and then since people actually atleast will know what i'm taking about, otherwise when you replace it with "metabolic acidosis" the layman won't know what you're even talking about lol.
