What are the three phases of sporting movements?
Preparation
,
execution
, and
follow through
View source
What is the purpose of the anatomical analysis of muscles in sporting actions?
To break down
important
parts
of movements
View source
What occurs during the preparation phase of a sporting movement?
Agonist
muscles are relaxed
Antagonistic muscles stay relaxed
Agonists
at shoulder and elbow aim
View source
What is the role of agonist muscles in the preparation phase?
They are
relaxed
to allow
contractions
View source
Why do antagonistic muscles remain relaxed during the preparation phase?
To allow
contractions
and sufficient
velocity
View source
How do agonists at the shoulder and elbow assist a basketball player?
They
help
aim
towards
the basket
View source
What happens during the execution phase of a sporting movement?
Agonist
muscles are activated
Signals sent to equipment
Antagonistic
muscles remain relaxed
View source
What is the role of agonist muscles during the execution phase?
They are activated to meet the
target
View source
What do agonist muscles signal during the execution phase?
They signal the equipment to
continue forward
View source
Why do antagonistic muscles stay relaxed during the execution phase?
To allow the
agonist
to
contract
View source
What occurs during the follow through phase of a sporting movement?
Concentric contractions
in
agonists
Produce force at
shoulder
and
elbow
Complete the follow through of the shot
View source
What type of contractions occur in the agonists during the follow through phase?
Concentric
contractions
View source
What is the purpose of the agonist contractions during the follow through phase?
To complete the follow through of the
shot
View source
What muscles are involved in shoulder flexion and elbow extension during sporting actions?
Shoulder Flexion: Agonist -
anterior deltoid
Elbow Extension: Agonist -
triceps
, Antagonist -
latissimus dorsi
View source
What is the agonist muscle for elbow extension?
Triceps
View source
What is the agonist muscle for shoulder flexion?
Anterio
deltoid
View source
What role do synergists and fixators play in sporting actions?
They stabilize the
shoulder joint
View source
How do muscles operate at the knee and hip for a gymnast moving to a squat?
Agonists
and
antagonists
work together
Synergists
stabilize the movement
Flexion
and extension occur at joints
View source
What is the primary action of the biceps during flexion to extension?
Agonist
View source
What is the primary action of the triceps during flexion to extension?
Antagonist
View source
What is the significance of the analysis of muscles in sports?
It enables understanding of
movement
mechanics
