This could be for a variety of reasons but the thing I think is most likely is that they could absorb oxygen much better avoid anaerobic respiration (low energy production)that creates lactic acid in the first place. If they are able to sustain aerobic respiration (high energy production) longer, they can have their bodily energy demands met and continue to do their activity never producing lactic acid.
The cause of delayed onset muscle soreness (DOMS) is separate from lactic acid but may be related in a person’s ability to metabolize and regenerate tissue as that guy clearly has an efficient body.
What about the infinite marathon runner from Stan Lee’s Superhumans show?
Dude could run indefinitely with no wear-down, and they found he wasn’t producing lactic acid like everybody else.
Is that really not related?
