1. INTRODUCTIONINTRODUCTION
SpeedSpeed is one of the most important skills in any
sport. We can say that speed increases depending
on strength.
At about 23 years of age23 years of age, we should have reached
100% our possibilities in view of this skill.
After flexibility, it is the second fastest involutive skillsecond fastest involutive skill
produced at age 25.
The development of speed depends on factorsfactors such
as muscles, nerves, genetics and the temperature of
the muscles.

2. DEFINITIONDEFINITION
SPEED is the physical skill that allows us to perform
movement in the minimum possible time.
The reaction speed and movement can involve one
part of the body or the whole body.
It can be manifested in:It can be manifested in:
- the distance covered in a given time (MOVEMENT SPEED)
- reaction to stimuli (REACTION SPEED)
- performing a gesture (GESTURE SPEED)

3. FACTORS DETERMINING SPEED

4. TYPES OF SPEED
1. REACTION SPEED: It is used to respond to a given stimuli (visual,
auditory, tactile...) in the shortest possible time. It is the interval of
time between application of stimulus and detection of a response.
This kind of speed is highly influenced by genetic factors and it is little
affected by training.

The starting shot a 100 meter race
2. MOVEMENT SPEED: It is used to cover a distance in the shortest
possible time. In this type of speed there is movement of the whole
body and it is determined by several factors: stride length, frequency
of segmental movements, neuromuscular coordination...
100 meter crawl in swimming
3. GESTURE or SEGMENTAL SPEED: It is used to perform movement
with one part of the body in the shortest possible time.
