Module 3 Flashcards
Which 4 different reasons why we might want to classify different types of movement for? HINT: chocolate chips so tasty
Coaching/training
Clinical
Skill acquisition
To study performance
Explain in phase movements
Bilateral homologous muscle groups contract synchronously
List 2 examples of in phase movements
Diving into a pool
Breaststroke
Explain anti phase movements
Muscles contract in alternating fashion
List 2 examples of anti phase movements
Front crawl
Gait
Define synergy
Coactivation of muscles about joints - multiple muscles contracting together
What does coactivation act as?
A stabilising, protective function
What does coactivation of muscles limit?
Degrees of freedom and eases motor control burden
List the 3 basic tenants of strength training
You can only train the muscle you activate
Muscle response is specific to the way we train it
Muscle growth is non uniform
What is the force generated by a sarcomere dependent on?
The number of cross linkages between actin and myosin
What is the magnitude of force related to?
Sarcomere length
What is force measured in the muscle related to?
The total number of activated sarcomeres in the muscle and therefore muscle length
Is force applied during a push constant or non constant?
Non constant
Measured force may be greater than or less than the external load at times, True or False?
True
Define moment arm
The perpendicular distance from an axis to the line of action of a force
