PE Paper 1
,Muscular System
,Functions of muscles with examples
● Sternocleidomastoid - helps with breathing process (endurance
events))
● Deltoid - abduction of shoulder (outward phase of star jump)
● Rotator cuff - stabilising muscle allowing rotation of shoulder
(throwing javelin)
● Pectorals - adduction of shoulder (upwards phase of press up)
● Intercostals - assists with breathing (endurance events)
● Triceps - extend the elbow (shooting in netball)
● Biceps - flex the elbow (drawing a bow in archery)
, Functions of muscles with examples
● Abdominals - flex the trunk across stomach (performing a sit up)
● Latissimus dorsi - adduction of shoulder (butterfly stroke in swimming)
● Quadriceps - extend the knee (kicking a ball)
● Hamstrings - flex the knee (hamstring curl on weights machine)
● Gastrocnemius - plantar flexion of ankle (standing on tiptoe to mark in
netball)
● Tibialis anterior - dorsiflexion if the ankle (foot making contact with a
football)
