The training of the biceps (III): Implied muscles 2

Written on December 13, 2010 – 8:13 pm | by F. Javier Molano

- Brachial previous: It is a muscle of very short distance, from the mean of the arm, until the elbow, being connected in the ulna. It is a direct flexor of the elbow that can shrink a lot, because it has a lot of muscle and little tendon. With the arm bended and the palm looking down you can notice it with easiness.

- Long Supinador or braquioradial: It is a muscle that undoes any forearm (it will be seen later on) rotation, to place it in their intermediate (that in which the thumb is guided to the mean) position.

This muscle is born in the arm almost to the height of the elbow and in its external part, until the forearm, in the radio almost until the wrist, in the part from the one  would be prolonged in the thumb.

It is appreciated with the arm bended and the thumb in the intermediate (looking up) position, as an it stands out muscular that is prolonged until the thumb in the forearm.

- Superficial flexors of the forearm: They are long muscles that are born in the inferior part of the humerus (bone of the arm), and that they cross the forearm to notice the bones of the hand and of the fingers, for they unite more than an articulation.

We will continue speaking of the importance of these muscles superficial flexors, and of the deep ones.

The reaction speed (IV): The complex time of reaction

Written on December 7, 2010 – 7:49 pm | by F. Javier Molano

As we have already commented, the complex time of reaction is the one that takes a long time in reacting to variable stimuli with answers that are also necessary to choose.

This capacity appears in sport many activities, especially in fight sports, collective, or opponents, in those that have to respond in an effective way before the opponent’s (a finta, a blow, etc) action, or of a stimulus that arises in the sport (the address of a ball, etc) action.

The fundamental characteristic of all these activities is the uncertainty that there are so much in the movements that we carry out like in the situations that provoke them. There are two types of uncertainty:

- On the election of the information: Perceptive – anticipation.
- On the election of the answer: Decision.

The difficulty to react to a movement depends on the quantity of uncertainties that are sink. It can be regarding the trajectory of an object, its speed, the movement of the contrary one, etc. And before this, the possible  answers among those that we have to choose the most appropriate.

To have to perceive more elements and the election of the appropriate answer lengthens the time of answer.

The complex time of reaction can be of the order of 0,25 and 1 second, and it can increase if they increase the number of alternatives among those that to choose the answer.

These times are too long before situations that leave at great speed happening. For that reason, if we don’t want to arrive late to all the places, it is necessary to look for resources to be able to react on time, and here it is where the anticipation enters in game.

Jump to the water (II): Description 2

Written on November 29, 2010 – 1:21 pm | by F. Javier Molano

2. Flight: We look for maintaining the secured height the maximum possible time with the body in tension. For this, we keep the low head and the arms stretched with the hands stuck, placing one on another one.

The arms press the head, right on the ears. Also we tightened the legs to each other, and we maintain the feet extended. Our body is tense and in a position that occupies its maximum length.

3. Entrance in the water: This tension is necessary to maintain it to enter in the water well. It is necessary to try to enter the water in the smaller possible space, avoiding to drop a clanger, aside from sprinkling much water and leaving us the gut red, restrain us in dry and so there is no sliding.

The idea can help us to introduce ourselves by a hoop totally, trying to splash less possible. It is important to maintain the tension in the body at any moment to enter totally straight.

If there is no tension, we run the risk of flexing separating the legs, among other things, what it can restrain us.

On the other hand, it is important to maintain the chin stuck to the neck to avoid us that the glasses can be cleared, or that water can enter inside them by the direct pressure of the water on the face.

4. Sliding: Within the water, we must avoid sinking us excessively, and it is necessary to look for the sliding forwards.

The impulse is necessary to take advantage of maintaining  the position. If we tried to give some movement of the arms, it can restrain in dry. It is not necessary to begin to swim until we do not understand that we restrained.

We are finishing the analysis of the technique. This gesture is quite complex, and it involves certain risks if it is not executed well and wisely. For that reason, more ahead we will speak how to learn it.
