The throwings are movements that try to add all the motive resources that the sportsman can develop, to apply the maximum impulse possible to an object and to send it to it as far as possible.
In the throwings an area exists for that reason, in the one that the pitcher can generate this force, and a launching area, to where he has to direct the device.
These areas are defined by a narrow mark that indicates the place through which have to pass the object, and also the limit that the pitcher doesn’t have to overcome.
It would be quite dangerous that the device could leave in any address, mainly when in some launchings, quite considerable (in javelin the 100 meters are been about) distances are reached, to part that if a limit doesn’t exist for the pitcher, the measure points could not be clarified.
These two aspects mark the general norms of the throwings. Not to spend of the limit and being able to direct the object toward where we want.
These norms tell us that the throwing is not a gross simple application of the force, and that we have a control and domain of this impulse.
Each one of the four throwing disciplines has some own characteristics that differentiate them.
The nature of the device forces to carry out a mechanics of different throwing, but all the throwings in its execution go by a series of phases.
These phases are repeated in all the throwings and it is something that they have in common.
It will continue.

In the cultural tradition of certain regions, games are included within the certain celebrations, in which they competed with respect to a number of activities which they comprised of the way of life of the region.
The people of the town measured forces (and in to some cases she continues it doing) in activities that they had very trained.
Between these activities we have been a wide range of activities, almost always tied with the way of life of the zone, as they can be the cut of trunks, launching of objects, and among others many…. the rise of heavy objects (stones, etc).
And it is that the rise of loads is one of the most habitual activities in our everyday life. From the professional who dedicates to move objects, for that the rise is a gesture that is repeated during hours throughout the day, until the person that in his house and he must raise some box, or simply to crouch itself to take a paper of the ground, all we must raise objects in our day to day.
We are going to include in this section crouching to take objects without weight of the ground because the mechanics of the movement is the same and the injuries that can be produced are of the same nature.
The rise of loads finds in the weight-lifting its expression in the form of sport. In the weight-lifting one looks for to raise the maximum possible weight from the ground to taking it over the head.
The competitions are divided in categories of weight, sex and age, as well as in different exercises from rise.
The weight-lifting requires the maximum development of the force and to dominate a technique serves that to remove us the maximum advantage from the movements, as well as not to injure to us.
The weight-lifting has become, in addition, in means to develop the force for other sports, of course, adapting the loads.
The movements of extension of combined legs and vertebral column are fundamental to improve in the scope of the jumps, races, displacements, rises of weights and maintenance of the vertical position, and for that reason the weight-lifting exercises are used to improve the power in many sports.
In the same way that the weight-lifting has application for other many activities, the gesture to raise objects becomes an essential movement to improve our ability and capacity to realise daily movements (to raise stairs, to run to take the bus, to take suitcases, etc).
That is to say, one becomes means of essential training for our day to day, reason why it would be quite interesting to include it in our plans of training.
In next chapters, we will shell the subject progressively, beginning by the fundamental precautions….

When we train the force in the gyms, we usually say that the biceps will work, when we want to train the flexion from the arm to level of the elbow.
We find more comfortable to identify this movement naming him with the name of the strongest muscle that intervenes in this action (the brachial biceps).
But in the flexion of the elbow more muscles intervene, and for that reason it would not be very correct to denominate this way it.
Here we will call each thing for their name for not tying us, because we will mention as much the muscle as the action, and we can make a mistake.
And it is that we want to analyze the characteristics and factors that influence in this movement, a little to define the possibilities of training and the methodology to develop it in a more complete way.
The flexion of the elbow is the movement with which we can bring near the faces previous of the arm and of the forearm, and with it the hand to the shoulder.
This action can be carried out bringing near the forearm regarding the arm (to lift a weight), or vice versa (dominated hung of a bar, in which we bring near the body to the hands).
The flexion of the elbow takes place for before this, and this lever they carry out it hence, the muscles flexors that are located in the part previous of the arm.
In next chapters we will speak of the muscles implied in the action.

The breathing is the first action that we carry out when being born, and the last that we make before dying. The breathing is the mechanism with which we carry out the exchange of gases with the exterior for the maintenance of the life.
To live we need to ingest periodically liquid and solid foods, to build our body and to regenerate the fabrics that go deteriorating.
But the breathing is a feeding that we have to maintain constant in all moment, to be able to continue alive.
We can live about fifty days without eating and not more than two or three without drinking, but without breathing we can die in about five minutes.
The data are symbolic and approximate to compare, but they cannot take like reference.
As essential activity for the life has an involuntary control, so that we don’t forget to carry out it (as the heart contraction, the digestion, etc), because we would put in our danger survival.
But contrary to the involuntary other activities, we can end up influencing in the way of carrying out it according to our will. If we want, we can change the rhythm and the breathing type that we carry out.
On the other hand, our emotions also alter the rhythm of our breathing (for example, like we collapse the breathing when they give us a fright).
We will continue…
