Speeds vary on technique
Mostly done in 3 steps
Very efficient
Manipulation of the torso and foot
Base starts with 2 foot base then moves to a 1 footbase
,
Locomotion, Limb
Manipulation

Type of Movement
Serial movement
Timing is everything
Has a defining start and end
Once Referee blows whistle till athlete goes back toplaying position
Importance- Lining up the shot to a teammate andtrying to score

Complexity
Complex task
Involves many different muscle groups in the body,such as upper leg muscles and the lower leg muscles.As well as Focusing on the lower half and feet.
Requires many cognitive processes to achieve a goal.

EnvironmentalRequirements
Open environment
The game takes place in an open environment.
Anything can happen. Since the task is part of the game it is in an open
environment.
There is no predicting what could happen during theevent, or what the event leads to. (Hopefully a goal)

Gliding Joint
Most important for thetask.
To be able to put bendon the ball, the foot hasto be able to strike theball from differentangles
Between the distal endsof the fibula and tibiaand the proximal endsof the talus

Physiological Analysis
PRACTICE. From a pickup game in the backyard to the WorldCup Finals this task is hard to do. Teammates need to practicethis early and often to understand how both parties canconnect to score. The athlete needs to work on muscularendurance so the body part in use is ready to go at all times.The body part also needs to have muscular strength. If thebody part is weak, the athlete will have trouble completing thetask. The athlete needs to work on the power, the agility of thetask, and accuracy for placement of the corner kick. The player
also needs to know how to use levers. Every time an athletedoes the task it will be different. If the athlete practices theywill be able to understand how much bend (HINT HINTWINK WINK) will be needed to place the ball to a teammateand to keep it away from the goalkeeper.

Social/Cultural/Psychological Analysis
It takes place in a team sport activity, but is doneindividually. Individual is looking for an assist.Fans from opposite team are yelling at you whileyour teams fans are cheering you on. This activity,if correctly done, can potentially win the game for at team. There is usually only one person on the teamthat does this task. If a team is lucky they can have 2
players that do it from opposite sides, not at thesame time.
Bend it like Beckham.

Muscular Analysis
Major muscles that areused are the:
Upper Leg Muscles -
quadriceps (Vastuslateralis, medialis,intermedius, Rectusfemoris), Sartoriusmuscles. Hamstrings(bicep femoris,semimembranosus,
semitendinosus)
Lower Leg Muscles-Gastrocnemius, tibialisanterior, soleus muscles

Spatial Analysis
Sequence 1 Frontal , anatomical position.
(just standing )
Sequence 2 (swing of the kick) Sagittal, bilateral movement,
hyperflexion of the leg which heis kicking the ball. The foot isdorsiflexed.
Sequence 3 (follow through) Sagittal, bilateral movement,
extension of the leg to kick theball. The foot is plantar flexedonce the player has contact withthe ball but the player mustcontinue the movement forpower.

Stability/Equilibrium
The Importance of stability and equilibrium of your body is veryimportant in the movement sequence of taking a corner kick, it helpsmaintain for movement to continue. The base of support of balance andkeeping your center of gravity is key to kicking a great corner kick.
In the first sequence the player is a anatomical position waiting to getpermission to kick the ball, so the player has center of gravity and stability.
In the second sequence the players combined center of gravity and line gravityis shifted because the player is moving in a rotary manner as he tries to gainpower in her/his kick. The player needs to keep arms higher than the center ofgravity for balance
In the third sequence the player continues to move in a rotary manner andfollows through with the kick as he still keeps his stability and equilibrium bymoving his center of gravity with the line of gravity to give power to the kickand keeping balance at the same time.
