IMPORTANT OF SPEED AND SPEED TABLE TENNIS

Is the speed with which I do strength training important?

Yes. Apart from the importance of the weight chosen to perform an exercise and the variables of which they are composed, the speed of execution has recently taken on great importance in all areas of sport and physical exercise.

An exercise performed at the maximum possible speed with a light weight (30% 1RM) is very far from performing the same movement with a weight around 80% of the 1RM and at a slow execution speed.

Execution speed as a load control variable in strength training

Currently, the quantification of the workload in different sports fields is carried out through a measurement of the speed of execution.

Not only is the weight that we "move" measured, but at the speed that we move or try to do it. And we emphasize trying, because although we cannot lift a weight at maximum speed, it is more important to perform the gesture at the maximum possible speed.

Can all populations perform strength training at high speeds?

Unless there is a contraindication for having a pathology for which movements must be carried out slowly and moderately, all populations can carry out this type of effort.

In fact, training at high speeds and with a low-medium number of repetitions is indicated in people with advanced age since it has been proven that greater adaptations are produced at the level of strength than training with more load and at moderate speeds.

It should be noted that over time, the fast fibres of our muscles lose their ability to work to contract quickly; therefore, if we give it that stimulus for as long as possible, the speed losses of these fibres will be less.

Our answer to this question is always the same: it depends on what you do. The body gets used to the stimuli that we propose to it throughout the training. With which, if we train at low speeds, our sensations may be of being less agile, slower since we reduce muscle activation and we have less strength gains.

Benefits of strength training at high speeds

Better neuromuscular adaptations.

Strength and power improvements in the face of the same weight moved at a lower speed.

Agility and mobility gains. This type of training is transferred to our day to day, feeling us with a new sensation of going with one more gear.

Increases in strength, speed, and speed.

Other gains and adaptations derived from effort, such as the improvement of the functioning of the cardiovascular system and the greater consumption of calories due to the intensity of the exercise.

THE IMPORTANCE OF SPEED IN TABLE TENNIS

Speed is the ability to perform motor actions in a minimum of time and with maximum efficiency. Force is perhaps the single most determining factor in how fast a movement can be executed. In this sense, speed is considered the rapid development of force. This has been defined in the theory of physical science as a magnitude that determines the relationship that exists between a space (e) and the time (t) used in the journey.

The time that elapses between performing a simple movement or not, will depend on the way in which force is used, although resistance will condition the possibility of chaining movements executed at high speed without reducing.

In tennis, speed allows you to increase the frequency and width of your strides. It allows to improve the coordination of movements during an anaerobic effort that quickly depletes energy in tennis, since coordination is a key part of the effectiveness in this activity. This term qualifies very diverse actions execution speed when hitting, intervention speed, starting speed, reaction time, coordination speed

In general and in tennis in particular, speed is determined by three parameters: reaction time, speed of movement and duration of execution.

Consequently, to endure a long match, the player must have resistance, but above all, he must be able, in a limited area, of about 15 by 16 meters, to chain numerous rapid movements over short distances. When a ball is thrown at him, he must show speed and precision to be in the best condition to hit it.

The essential qualities of the tennis player to improve speed are: a fair and fast information capacity, a fast decision making and an ability to react, coordination, dynamism, concentration and effective racing technique

TYPES OF SPEED APPLIED IN FIELD TENNIS

As has been observed, speed manifests itself in different ways; in tennis you should not only work on the specific, but on the types of speeds that the specialty requires:

BASE SPEED:

It refers to the greatest displacement capacity in the unit of time. According to research, this (maximum) speed is carried out over the initial 60 meters of a race, since from this distance the intensity decreases, because the pace of movement cannot be increased. The main factors that influence this base speed are three:

The Coordination of nerve impulses

The Resistance

This has the purpose of making nerve impulses act delaying fatigue through contraction and muscular tension of antagonists when agonists are shortened. For a correct methodology in the execution of the race, one must work at a speed that allows the perfect execution of the leg tandem, starting at a controlled rhythm, to increase as we control the synchronization and ease of movements, until reaching the maximum execution.

Speed Resistance

It is used to maintain the high cyclic-acyclic speed for as long as possible. This endurance time will give the ability to make greater efforts to endure what a match of 3 or more sets will give.

With this training, maximum acyclic stimuli of short duration are achieved, but which are maintained for as long as possible, so the body must be prepared to withstand it. Its objective is to intervene in the speed of movements - acyclic displacements, maintaining the intensity as many times as possible.

They are cyclical speed actions that are similar throughout a match. Many are the movements that are made throughout it, from the front-diagonal-lateral-back race, which must be adapted to the situations of the game to the sending of the ball by the opponent and to its control.

To improve this type of speed, through the cognitive aspects in played forms or strategic movements, it is necessary to:

Decrease thinking time, from decision to execution.

Mixing tasks with two or more objectives (depending on the opponent, in anticipating the execution of the stroke, in hitting when visualizing the opponent, in the selection of the stroke based on the reception of the ball, etc.)

Establish Comparisons Of Lived, Current And Future Situations.

Increase the speed of actions, through acceleration, relaxation and muscle contraction of the upper extremities when striking.

Technical situations, with performances at high speed and forced situations (control over hitting).

Alternating and keeping the rhythm of the game, looking for the one that suits us at all times (press, slow down, etc.)

It is measured by the ability to get to another place as soon as possible. The movements in tennis are usually made mainly lateral, diagonal, front, back; therefore, the displacement race will be worked mainly taking into account: its direction, variations and the difficulty of the semi-stop at the right moment, to hit correctly, taking into account space-time.

Reaction Time

The speed has been developed and analysed by many authors and in many ways, for many years the ability to react in the shortest possible time to a given stimulus has been called reaction speed, but contradictory authors already.

In this way we can differentiate two types of reaction times: simple reaction time and discriminative reaction time; The first one deals with the specific response that is given to an already known stimulus can be explained in a very simple way, taking into account that the stimulus is always captured by the senses and the response that is given is a motor reaction already known or that the athlete for various reasons has already used it before. Reaction time in tennis is defined as "the time it takes a player to respond to a stimulus” and is equal to the latent time.
