WHY DO MUSCLE
ACHES AFTER DOING
A WORK OUT AT
GYM?
1
IT’S NORMAL TO
EXPERIENCE
MUSCLE PAIN
AFTER
EXERCISING IF IT’S
BEEN A WHILE
SINCE YOU WERE
ACTIVE OR
PERFORMED A
CERTAIN
MOVEMENT. 
Normal
Experience
2 Happens after
exercise
3 Performed a
certain Movemnt
DMOS
This type of pain –
called delayed onset
muscle soreness.
Generally develops
several hours later and
exacerbates over the
next few days.
THE EXERCISE THAT INDUCES DOMS
Dumbells
Walking down a set of stairs
Known as an eccentric (lengthening) muscle
contractions
DOMS is technically
considered an indicator
of “muscle damage”, as
muscle function
decreases.
But it appears that very
few muscle fibers are
actually injured or
destroyed (less than 1%
of total muscle fibers).
FINDINGS
connective tissue within the muscle
appear to be more affected by
eccentric contractions.
DOMS IS NOT A
WARNING SIGN NOT
TO MOVE THE
AFFECTED MUSCLES
ECCENTRIC EXERCISE TRAINING PRODUCES
GREATER INCREASES IN MUSCLE STRENGTH AND
SIZE WHEN COMPARED WITH CONCENTRIC
EXERCISE TRAINING, 
DON’T BE AFRAID OF DOMS
