thigh muscle
quadricep groups
shin muscle
tibialis anterior
back muscle
latissimus dorsi
top shoulder muscle
deltoid
bottom shoulder muscle
rotator cuffs
bum muscle
gluteals
back of thigh muscle
hamstring
back of calf muscle
gastrocnemius
function of abdominals?
provide core strength and bend at spine
function of biceps?
bend arm at elbow
function of deltoid?
raise arms
function of triceps?
straighten am at elbow
function of gluteals?
create rotation at hip
function of quads?
straighten leg at knee
function of rotator cuffs?
stabilise shoulder, rotate shoulder
function of hamstring?
bend leg at the knee
function tibialis anterior ?
bend at ankle
function of gastrocnemius?
straighten at ankle
function of hip flexors?
create rotation at the hip
function of sternocleidomastoid?
rotates the head and flexes the neck.
aids respiration when exercising
function of latissimus dorsi?
pull arms down at together at back of body
function of pectorals?
to adduct arm bring it across the chest
What do muscles work in?
pairs
How do muscles pull?
can they push?
by contracting
CANT push to produce an opposite movement
What does concentric contraction mean?
muscle shortens and contracts.
What does Eccentric contraction mean?
muscles lengthening and contracting
What does isotonic muscle contraction mean?
contracting with movement (exercising)
What does Isometric muscle contraction mean?
contracting muscles without movement (plank)
muscles still working just not moving
What are the 2 types of isotonic movement?
concentric contraction
eccentric contractions
What is antagonistic pair?
one muscle contracts and the other relaxes
What is an agonist?
where the contracting muscle becomes shorter
When you flex your knee what is the agonist and antgonist?
hamstring - agonist
quads - antagonist
What is an antagonist
Where the relaxing muscle become longer
Examples of antagonistic muscle pairs?
biceps and triceps
back and chest
abs and lower back
shoulders and chest/back
quads and hamstring
tibialis anterior and calf
factors that affect your health
smoking
diet
overworking
over drinking
illness/ injury
drugs
weight
What is fitness?
ability to meet the demands of physical every day environment
What is health?
