ENDURANCE THEORY
1.- DEFINITION
Psycological and physiological capacity to tolerate fatigue and / or making long a period. The
body’s ability to withstand fatigue and/or any kind of physical exercise over a prolonged
period.
Being physicaly active is healthy because is related with cardiovascular and respiratory
systems.
2.- TYPES OF ENDURANCE
The level of intensity determines the types of endurance. The “energy ” used by the muscles
to move is obtained from a substance called ATP, muscles need it to do the contractions, to
exert force or to move.
There are 2 types depending on the intensity of the effort.
2.1 The Anaerobic way
Anaerobic means "without oxygen." The muscles do not have time enough to use O2 for ATP
production, so our body uses other sources (like glycogen) which immediately run out, causing
the athlete to faint.
•They are high intensity efforts (between 80-
100% of the MHR) that usually last between
30 seconds and 4-5 minutes.
•
It is not recommended to do too many
anaerobic trainings at your age, and when is
done it should be done with an optimum base
of aerobic preparation.
•Examples: short and intense; racing (400
metres), cycling (climbing a mountain or a
steep slope); swimming (50 metres max.
speed)... any sport at a high intensity becomes
anaerobic.
There are two paths of getting ATP without O2, the
Alactic and the Lactic:
Anaerobic Alactic.
•This is the first path the body follows to get the energy, and it uses the ATP stored
in the muscles.
•There are no waste products, but it can be used only for a very short time (from 10”
to 20”) and in very intense activities (90-100 % of the maximum capacity).
