The force

Strength:
Strength is the capacity or conditional driving quality that is characterized by processes of transformation of enegia. As it involves the physical condition define the strength and the ability to overcome the resistance produced by muscle contraction, ie the ability to perform work.
- Different types of force:
In reaching a displacement or acceleration of a body applying a force F = m * a. This is a Finama force with which a body moves, according to mass and acceleration of that, we can distinguish 3 types:
-Maximum force: mass acceleration maxima and minima.
-Force explosive: small mass and maximum acceleration.
-Strong resistance: mass and acceleration reach average levels of their relationship.
One type of muscle contraction called isometric, generates a force not mass movilizaninguna. It is a static force does not produce a movement, but allows the maintenance of a posture.

- Factors influencing the force:
The quality of the force is determined by:
"The muscle structure itself: it depends on the orientation and types of muscle fibers, also depends on the length of the muscle.
"The temeperatura: muscle contraction is faster and more powerful when the internal temperature is slightly higher than normal.
-Skeletal system and articualar: The force depends on the lever that made the movement.
"The level of training: training with l improve the factors that influence the level of muscle strength: the metabolism and fuel tanks that allow: an increase in muscle fiber thickness and the number of myofibrils and the delay in the appearance of muscle fatigue.
"The age and sex.

- Training systems:
Keep in mind the following parameters:
"The media are the devices we use in the exercises to create burdens that have to mobilize the muscles.
"The point indicates the type of strength exercise.
"The charge refers to the weight to be mobilized.
"The repetitions, along with the load, determine the workload.
"The speed of execution indicates the intensity of exercise.
"The determination of the recovery pause between each set of exercises.
