A. Understanding eye-hand coordination
In general, coordination is defined as the cooperation of the procedure or something different,
physiologically coordination is defined as the cooperation of the central nervous system with the muscle
to produce energy, both inter and intramuscular.
In broad terms, coordination is often also referred to the term or name for several capabilities that
support the cooperation of the different motion processes, for example in learning, coordination is
divided based on rough coordination (ability to learn movement), and smooth coordination is stable
(ability to change and adjust the motion) .
Coordination is a very complex biometric capabilities, close coordination to do with speed, strength,
endurance and flexibility, and they all contributed and blended in motor coordination, and therefore to
each other have a very close relationship. If one element is missing or less developed, it will affect the
perfection of coordination. Coordination of the various parts of the body, including an ability to display a
model of motor skills. These capabilities are intended to control the free body parts involved in a motor
skills model. These capabilities are intended to control the free body parts involved in a complex motion
models, and combine these parts in a movement, a smooth movement, the success of efforts in
achieving a goal.
Thus, coordination is the quality of muscles, bones and joints, including the five senses in producing a
motion. Coordination capability is an actualization of the components of the movement in question,
include: energy systems, contraction of muscles, nerves, bones, joints, eyes and senses.
Accordingly, coordination is closely related to the stimulus or visual sensory stimulation, sense of
position and balance, and kinesthetic feelings. Components include a balance of coordination (especially
related to the muscle), the ability of the combination of motion (the appearance of motion
simultaneously and continuing), agility, and reaction capabilities.
Bompa (1969:64) says that: "Coordination is a very complex biomotor ability, associated with speed,
strength, endurance and flexibility. Furthermore, Singer (1983:167) says that: "The coordination of the
various parts of the body including an ability to display a model of motion." These capabilities are
intended to control the free body parts involved in complex motion models and combine these parts in
a smooth motion model.
Then further Harsono (1988:65) points out: "Coordination is the ability mengintekrasikan variety of
different movements into one single pattern of movement." Next Sajoto (1988:53) points out:
"Coordination is the ability to unify the various movements that separate the nervous system into one
efficient movement patterns.
From the various opinions mentioned above can be concluded, that coordination is the ability to
combine several movements without tension, with the right order, and perform complex movement
regularly (smoothly) without excessive energy expenditure
Based on these explanations seems that the role of eye-hand coordination is very important and require
attention to be developed, because the eye-hand coordination is a supporter of doing a series of
movements in the pattern of motion, including the ability to pass down in the game bolavoli.
B. Measurement of eye-hand coordination with eye-hand coordination test
To measure the hand eye coordination
b. Facilities / equipment:
circular target made of paper with a diameter of 30 cm.
Chalk or tape to create borders.
Shells / paper
Target placed at shoulder-high wall of the test participants. Participants test throws behind the line as
far as 2.5 meters. Test participants were given the opportunity to throw the ball towards the target, and
catch the ball back as much as ten times replicated by using one hand. Test participants are given more
opportunity to do throwing the ball catching using one hand and arrested by the hands of as many as 10
different replications. Each participant was given the opportunity to do the experiment so that they can
adapt to the assay used.
The scores are calculated is a valid throw, the throw is on target and can be arrested again, and on the
implementation of throwing catching the ball, the test participants did not step on the boundary line. A
throw will earn a score of 1 (one) if the throw is on target and can be recaptured correctly. Total score is
the overall result of throwing catching the ball with the same hand and with a different hand.
