Characteristics of skeletal muscle are...
Striated muscle
Under conscious control
Non-fatiguing
Fatiguing
Characteristics of cardiac muscle are...
Involuntary
Under conscious control
Non-fatiguing
Only found in chambers of the heart
Characteristics of smooth muscle are...
Involuntary
Under conscious control
slow speed of contraction
fatiguing
Functions of smooth muscle:
Helps blood travel through blood vessels
Helps heart contract
Helps food travel through digestive system
Attaches to muscles and allows movement

Agonist is...
the muscle that support the agonists.
the muscle that works in opposition to the agonist.
the muscle that stabilises the joint stopping any unwanted movement at the origin.
the contracting muscle responsible for causing movement.
Antagonist is...
the muscle that support the agonists.
the muscle that works in opposition to the agonist.
the muscle that stabilises the joint stopping any unwanted movement at the origin.
the contracting muscle responsible for causing movement.
Fixator is...
the muscle that support the agonists.
the muscle that works in opposition to the agonist.
the muscle that stabilises the joint stopping any unwanted movement at the origin.
the contracting muscle responsible for causing movement.
Synergist is...
the muscle that support the agonists.
the muscle that works in opposition to the agonist.
the muscle that stabilises the joint stopping any unwanted movement at the origin.
the contracting muscle responsible for causing movement.
The bicep is the agonist/contracts (1)
to lift the weight/flex the arm at the elbow (1)
the triceps are the antagonist/relax (1)
to allow the contraction of the agonist/bicep (1)
The tricep is the agonist/contracts (1)
to lift the weight/flex the arm at the elbow (1)
the biceps are the antagonist/relax (1)
to allow the contraction of the agonist/tricep (1)
The bicep is the agonist/relaxes (1)
to lift the weight/flex the arm at the elbow (1)
the triceps are the antagonist/contracts (1)
to allow the contraction of the agonist/bicep (1)
Role/ function of a fixator muscle is...
Fixators contract isometrically (1) by stabilising the (origin) of the agonist/muscle (1) they help support the agonist to carry out the function by stopping unwanted movement/carry out the movement (1)
Contract concentrically (1) helps support the agonist (1) cause movement at a joint (1)
Contract eccentrically (1) by stabilising the (origin) of the agonist/muscle (1) they help support the agonist to carry out the function by stopping unwanted movement/carry out the movement (1)
Isometric contractions are...
when a muscle lengthens under tension.
muscle contractions that do not create movement whilst under tension.
when a muscle shortens under tension.
Sometimes known as the negative phase of a muscle contraction.
Concentric contractions are...
when a muscle lengthens under tension.
muscle contractions that do not create movement whilst under tension.
when a muscle shortens under tension.
Sometimes known as the negative phase of a muscle contraction.
Eccentric contractions are...
when a muscle lengthens under tension.
muscle contractions that do not create movement whilst under tension.
when a muscle shortens under tension.
Sometimes known as the negative phase of a muscle contraction.
Type 1 muscle fibre characteristics:
High speed of contraction, low aerobic capacity, low myoglobin levels , high force, high fatigue levels, low fat stores and maximum intensity.
Slow speed of contraction, high aerobic capacity, myoglobin levels high, low force, low fatigue levels, high fat stores and moderate intensity.
High speed of contraction, high anaerobic capacity, low capillary density , high force, high fatigue levels, high glycogen stores and high intensity.
Type 2 (b/x) muscle fibre characteristics:
High speed of contraction, low aerobic capacity, low myoglobin levels , high force, high fatigue levels, low fat stores and maximum intensity.
Slow speed of contraction, high aerobic capacity, myoglobin levels high, low force, low fatigue levels, high fat stores and moderate intensity.
High speed of contraction, high anaerobic capacity, low capillary density , high force, high fatigue levels, high glycogen stores and high intensity.
Sacropenia is...
an increase in muscle mass - increase in power and strength of muscles
a decrease in muscle mass - decrease in power and strength of muscles
a muscular disease.
a type of muscular contraction.
Cramp is...
is an involuntary sustained skeletal muscular contraction/spasm (1) which prevents muscle movement (1) which occurs due to dehydration/a lack of electrolytes/salt
is an voluntary sustained skeletal muscular contraction (1) which allows muscle movement (1) which occurs due to weeks of training
