1.1a Skeletal and muscular systems
Joints, movements and
muscles
Functional roles of muscles
and types of contraction
Analysis of movement (analyse movement with reference to)
Skeletal muscle contraction
Muscle contraction during exercise of differing intensities and during recovery
roles of muscles
agonist
antagonist
fixator
types of contraction
isotonic
concentric
eccentric
isometric
joint type
movement produced
agonist and antagonist muscles involved
type of muscle contraction taking place
structure and role of motor units in skeletal muscle contraction
nervous stimulation of the motor unit
motor neuron
action potential
neurotransmitter
‘all or none’ law
muscle fibre types
slow oxidative
fast oxidative glycolytic
fast glycolytic
recruitment of different fibre types during exercise of differing
intensities and during recovery
