, Muscular adaptions psiapurpose :
define and body
•
move
provide efficient and effect force
•
.
muscles adapt to demands
•
response to demand . changes ability to extract Oi , choose energy sources +
rid of waste
what happens when we train
1) aerobic exercise -
slow twitch fibres t in size .
( nos dont change tho )
2) T fibres =
more space for mitochondria / more + bigger )
↳
muscles can produce more aerobic energy + improve performance
↳ all
energy made in mtd . Bigger mtd =
bigger energy made
3) collagen replacement in tendons + ligaments
↳ thicken =
stand more muscular force
T placed force
-
and I are made of collagen -
exercising =
body makes
collagen to repair / heal .
Poor blood SUPPLY . longer to heat
4) muscles =
flexible →
contract WI greater force
5) increase in glycogen stores
Train for longer cause have more glycogen
-
6) myoglobin in skeletal muscles T
-
more Oi can be stored in muscles + transported to mtd
7) muscles , bones . ligaments =
stronger
81 more synovial fluid (short term )
9) t in minerals in bones ( immediate )
, Overload Principle
=
continually challenge muscles .
dont overload + cause injury .
•
muscles will adapt to heavier toads as they grow = T strength
what happens to overloaded muscles
improved trained
°
neural paths to muscles help muscle generate more force = handle weight
progressively
•
01 stimulates bone growth +
strengthens ligaments that link bones
and tendons that attach muscle to bone .
