400m S-L questions

The jump-run-bound circuit is a continuum. Very short break between each, maybe 5-10sec. It’s 2-3x of the entirety.

The furthest that I take them on the running A’s is 60m. It is very tough.

Do you feel that circuit directly improves performance, or does it serve to enhance the quality of later special endurance training? Both?
