Isometric training two days before fast and slow eccentric training led to lower reductions of maximal voluntary contraction, and yes, smaller increases in muscle soreness.
Some would rather walk the " plank" than " plank" down the time to break the " plank" record but if you've got the strength, it all comes down to " isometrics" .
Same goes for indirect muscle recovery markers, like creatine kinase and muscle voluntary isometric force contraction, where active cooldowns don't seem to change much of these recovery factors.
