What are the functions of skeletal muscles
action- movement produced when a muscle contracts concentrically in isolation
Other roles:
agonist- muscle producing the desired movement by contracting either concentrically or eccentrically
antagonist - muscle which muse relax to allowed desired movement to occur
Fixator- stabilises a body segment to allow another muscle perform an action
synergist- cancels the unwanted action of the agonist
Phases of soccer kick
At the acceleration phase describe the predominant movement and the muscles responsible for producing the action
The predominate movement: hip flexion
List the muscle responsible for hip flexion:
iliopsaos (major hip felxion)
TFL (hip abduction & internal rotation)
rectus femoris (knee extension)
pectineus (hip adduction)
sartorius ( hip abduction & external rotation)
Which muscles are recruited first
Which muscles are recruited first?
- ones requiring the least synergy
- muscles that cross one joint recruited first
What is the role of the recruited muscle and what muscles are stabilizing the hip
Role of recruited muscle:
-prime mover
Stabilizing the hip joint:
