1. INTRODUCTION.

They are essential for a sportsman to carry out sport activities in an

appropriate way.

2. THE COORDINATION

Ability to develop ordered actions under brain action.

2.1. TYPES OF COORDINATION

There are two types of coordination:

� DYNAMIC GENERAL COORDINATION

Movements that require the fitting of all the parts of the

body and in most cases, they imply locomotion.

� VISOMOTOR COORDINATION

Activities which establish a relationship between the objective

and one part of the body. For example, score a goal, a basket,

play the piano…

This type of coordination is the specific characteristic in the

learning of skill exercises.

It could be classified into:

EYE-HAND, actions where we have to observe the mobile and hit it with the hand. Example: tennis,

handball, basket, hockey…

EYE-FOOT, actions where we have to observe the mobile and hit it with the foot. Example: football.

2.2. FACTORS THAT INFLUENCE THE COORDINATION

Coordination is caused by how the nervous and the locomotor systems

work. The factors are:

� THE TIREDNESS.

� THE NERVOUS TENSION

� THE AGE

� THE LEARNING LEVEL

� THE PHYSICAL CONDITION

� THE NUMBER OF MUSCLE GROUPS INCLUDED IN THE

MOVEMENT

� THE PART OF THE BODY

� THE DIRECTION OF THE MOVEMENT

3. THE BALANCE

Ability of the body to keep a position contrary to gravitational force.

3.1. TYPES OF BALANCE

There are 2 types of balance when talking about human beings.

� STATIC BALANCE. Ability to keep a position on a stable base

without movement of the body.

� DYNAMIC BALANCE. It allows us to keep the desired position in

spite of the changes of position of any movement.

3.2. FACTORS THAT INFLUENCE THE BALANCE

The most important are:

A. THE HEIGHT OF THE CENTRE OF GRAVITY. B. THE WIDTH OF THE CENTRE OF GRAVITY

C. THE BODY WEIGHT

D. THE STRENGTH E. THE COORDINATION F. THE HEIGHT OF THE SUPPORT

4. THE AGILITY

Quality which is the union of the speed, the strength, the flexibility,

the coordination and the balance.

It’s the muscle and joint ease to make any movement. It’s essential in

the physical condition. It applies to human movements in which the body

turns, bends, jumps, rolls…
