api considerations Flashcards
What should the golfer have going into back swing?
Good base of support, centre of mass belly button which is remaining lower to the ground, better support which remains steady rather than unbalanced through backswing through storage of rotation and flexility. elbow should be flexed and posterior deltoid should be facing the target. Wrist flexors/extensors
What happens if gofers too far away with irons?
extending arms too early, meaning decrease in explosive strength and power, less angle of attack, won’t have as much distance as competitors so will weaken
Hips may go too soon?
Lead to loss of power,
How does angular velocity and inertia relate?
When body is close to the point of axis of rotation with width working as one can increase velocity, decreasing the inertia
why is it good to have your arms together?
Keep it on plane at top of backswing and put it on desired plane helping create a square club face
The law of acceleration?
More storage of power increases the accerlation, increasing distance.
What happens if golfer doesn’t hinge earlier?
Create more of a flat, less angle contacted swing
Why is it better hitting it inside to out?
Create more with create squarer club face
What are the core skills?
course management- putting driving short irons long itons kid irons fairway woods playing from different lies
what are the advanced skills?
course mafnement distance control putting 10 foot/up hill/downhill bunker play flip shot spin contro draw/fade mid draw/fade long ifons fairway woods/hybrids- draw/fade driving/ draw/fade playing from different lies ball above feet
What is the explanar usage?
can aid swing path as weakness
What should the set up phase be?
wide legs not too wide to restrict royation, the length between the performers stance is proportional to the hips. Needs good static strength- the splits or wall sits.
The centre of mass should be lowere to have a better base of support lower to gravity- athletes should bend illopsas and flex the bicep gemiréis aid squats and
What is the phase of the backswing?
The performer rotates their abdominals, torso and left/right hip to ensure this flexible rotation and create a coil strength . this creates strong elastic strength. the force produced will also be dependent on stretch reflex of the hip muscular extensiabilty of the knees illopsas gluteus maximas middle deltoid posterior
His left elbow begins to flex when reaching the 90 degree mark. Because of the flexion at the elbows his biceps brachii concentrically contracts
When taking the club back Ernie‟s‟ left shoulder horizontally adduct to the body and the left abducts
away from his body,
performer will open their knees and move them towards the target to allow more of a abdominal torn
What is the downswing?
The performer produces good shoulder rotation to allow for storage in the elastic strength which will then be driven through the hips and used by the stretch reflex to delay the hands being extended further creating lag. n1 n2 . the torque produced is the shoulders /hipss
the deltoids adduct back to the shoulders towards the ball to uniate the rotation
the connection allows for both arms to addict with the tricep bracho isometricallt contractinf due to tension
biceps concetrically contract
due to the weight distraction the quadriceps flex and isometricaly contract
through the ball both arms are isometriclwly contracting
What is the follow through phase?
The performer slowly decelerates and creates energy onto the ball along with heat and friction
hinging thr wrists are important as it can allow a doh ward pressure exerted into the ball
Applying projectile motion to the ball flight
having a higher ball flight will decrease its velocity over time as it’s getting further away from gravity initially reaching a peak which then the ball will go faster . the greater the initial velocity is the higher the ball travels as it is able to fight the force of gravity and air resistance for a longer period of time
better having a higher projectile force as it’s in the air for longer- done through an increase in angular velocity
What type
of rotation is the backswing?
abduction/adduction, keeping the head still stabilises the swing
What is one of the progressive practices for fleixkbitt?
Developing flexibility is essential in golf and one way is to do 10 seoncds per muscle for 10 minutes, can limit injury and increase elasticity around a joint.
Stretching the adductors in the hip rotation can slow for more of a rotation and an increase in strength being applied through the ball. Increasing the whole velocity and distance.
static stretching- focus on the base of keeping the body still by using walk sits to increase strength
How could plyometric be a plan?
warm up- do a quick jog to loosen the elasticity of the joints and tension. do some static/dynamic lunges
first session- do simple push ups as it would concentrically and eccentrically contrast the biceps and triceps which are good for the back swing structure of having a good flex/hinge
(as long as they are experienced) to delay the stretch reflex similarly needed in golf to delay the effect of the hips
try first jumó onto a shock sorb pad
frog hops with more test
to make it more friendly jumó in the same spot
add some russian twists to aid the rotation in the abduction of the swing repeat these for around 11 times x 3 then increase the intensity next session
1 small box jump each session
second session- delaying the amount of rest periods to stress the performers vbiceps and indicate the lactic acid syste. add in some box jumps to try and stimulate the concentric contraction after the eccentric contraction
good for delaying injuries
start working on broad jumps with measuring each session. using tape
star jumps distance abduction
scissor jumps slowly- hood for the gastrocnemius and bicep femories strength.
later could add weighted vest
increase box jumó distance
third session- forward back jumps lead to better balance and stability as unknown where landing- increasing power and explosives. try and increase the intensity with decreasing of rest breaks
increase box jump height
jumping lunges- to try and engage in the explosive power between strength and weight shift activating core
double leg butt bht kick boost niceto femories contractions
why is it better for a performer to have a shorter projectile path?
to not be affected by the wind and air resistance . Has a more true parobla when there’s more force applied to the ball
