muscluar system Flashcards
3 long term effects muscular system
increased muscle size
more effective blood supply
increased hypertrophy
improved muscle cocordination
3 short term effects muscular system
bigger muscles
increase muscle fatigue
increased muscle soreness
what is the fixator
the bone that holds the agonist still
what is the prime mover
that muscle that contracts creates movements
what is the synergist
helps to create movement
what are the 3 isotonic contractions
concentric
eccentric
isometric
what is a concentric contraction
muscle shortening
what is eccentric contractions
muscle lengthening
what js isometric contractions
no movement but still contracting
what are the 2 simple twitch fibres
fast twitch
slow twitch
what is the structure and function of fast twitch and sporting example
fibres are pale
contract quickly
get tired quickly
short distance 50m sprint
what is the structure and function of slow twitch and sporting example
deep red fibres
contract slowly
work long duration
long distance marathon runner
what is the type 1 muscle twitch fibre and its functions
slow oxidative fibre
contracts slowly
use aerobic respiration to produce ATP
slow to fatigue
long duration
what is the type 2A muscle fibre type
fast oxidative glycolytic
fast contractions
use both anaerobic and aerobic respiration
what is the type 2B muscle fibre
fast glycolytic
use anaerobic respiration
fast contractions
large amounts of glycogen
