DOMS - Class 6 Flashcards
DOMS
delayed onset muscle soreness
what is DOMS
soreness and discomfort 24-72 hours after an unaccustomed bout of exercise or activity
when is DOMS more likely to occur
repeated eccentric efforts
potential mechanisms are
unknown
mechanical, chemical and/or neurological
what does early research blame DOMS on
lactic acid buildup after exercise
but this has been largely disproven
after 1 hour of recovery
nearly all lactic acid is removed from skeletal muscle and blood
what does current research suggest
DOMS is linked to some form of contract induced, mechanical disruption of muscle fibers and CT
mechanical disruption of muscle fibers and CT –> current research
elevate serum creatine kinase present for several days after exercise
accompanied by inflammation and local edema
there is a temp loss of
strength
both precedes and persists after sensation of soreness
what is marginally successful at best
prevention and tx
best strategies
frequently repeating and progressing exercise intensity
repeated bout effect
bout of eccentric exercise may protect the muscles from subsequent bouts of exercise
tx for DOMS
continuing exercise
modalities
nutritional supplements
compression sleeves and salicylate topicals
continuing exercise –> tx
that caused the DOMS
does not worsen damage or slow recovery process
modalities –> tx
heat, ice, stim, massage
all show mixed evidence at best
