Correct grip Serve

Currently , the valuation of the plea withdrawal has increased significantly in world tennis. Clearly the serve is one of the most important fundamentals of tennis field , with primary factor in the victories of the practitioners of the sport .

However , many practitioners of shoes that start in the sport without the aid of a skilled professional end up carrying the sack with some incorrect movement patterns , hindering the evolution of this very foundation so important .

One of the major mistakes is using the incorrect grip . Much of practitioners hold the racket with the Western forehand grip ( Figure 1 ) .

                                                                Figure 1

With this type of grip you lose the levers of the body that generate power in the coup , and limit the player to serve only with the flat serve ( stoned ) .

The big problem the wrong way to handle the defects are generated , which in turn are very difficult to be corrected by teachers . The great difficulty in removing these vices is due to the fact at the time that the teacher will change the grip of the student, he feels much laxity during the course of withdrawal , because using the correct grip ( see below ) the use of wrist during the sack is widely used.

Given this information , what is the proper way to hold the racket to cash out ? The literature shows that the most appropriate is the continental grip ( Figure 2 ) .

                                                                   Figure 2

 With the Continental grip , it takes a larger aid of the lower limbs , trunk , shoulder, arm and forearm to generate power in the coup . Thus , since the beginning of learning the player is already stimulated to work throughout the body to carry the loot . Players holding incorrectly , have a limitation of motion mainly upper limbs , reducing significantly the generation of power in the coup , and increase the likelihood of injury .

Another important factor is the ability to make withdrawals in effect . The handling of the racket with the Continental grip much more freedom to move the wrist at the time of withdrawal, allowing counter with racket on the ball at different angles . From the racket - ball contact angles in the sack with other effect arises . Have the players who handle the racket handle with incorrect lose the freedom of movement of the wrist, restricting the ability of the player to vary the serve .

The great difficulty in learning the Continental grip is to hold that way at the beginning of learning . As discussed above , with the use of this grip handle is very large , and this overload on the handle generates firmness loss at the time of the coup . However , as the stimulus for draw with the continental grip increases , the region of the wrist is gaining more strength , decreasing laxity , besides having considerable power increase .

From the second training with the Continental grip month , the evolution of looting increases considerably, both in increased power generation and in effect. Therefore , always start the foundation serve using the Continental grip , because the long term benefits are huge .

Empunhadura correta do saque no tênis de campo

         Atualmente, a valorização do fundamento saque tem aumentado de forma expressiva no mundo tênis. É evidente que o saque é um dos fundamentos mais importantes do tênis de campo, sendo fator primordial para as vitórias dos praticantes da modalidade.

      No entanto, muitos praticantes de tênis que iniciam no esporte sem auxílio de um profissional especializado acabam realizando o saque com alguns padrões de movimentos incorretos, dificultando muito a evolução desse fundamento tão importante.

         Um dos principais erros cometidos é a utilização da empunhadura incorreta. Grande parte dos praticantes seguram a raquete com a empunhadura Western de de forehand (figura 1).

Figura 1

           Com esse tipo de empunhadura você perde as alavancas do corpo que geram potência no golpe, além de limitar o jogador a sacar apenas com o saque flat (chapado).

           O grande problema de segurar de maneira errada são os vícios gerados, que por sua vez são muito difíceis de ser corrigidos pelos professores. A grande dificuldade em retirar esses vícios se deve ao fato de no momento que o professor vai trocar a empunhadura do aluno, ele sente muita falta de firmeza durante a realização do saque, pois utilizando a empunhadura correta (ver a seguir) à utilização de punho durante o saque é muito utilizada.

         Dada essas informações, qual a maneira adequada de segurar a raquete para sacar? A literatura mostra que a empunhadura mais adequada é a continental (figura 2).

Figura 2

           Com a empunhadura continental, é preciso um auxílio maior dos membros inferiores, tronco, ombros, braço e antebraço para gerar potência no golpe. Sendo assim, desde o início do aprendizado o jogador já é estimulado a trabalhar todo o corpo para realizar o saque. Jogadores que seguram de maneira incorreta, possuem uma limitação de movimento principalmente de membros superiores, diminuindo de forma expressiva a geração de potência no golpe, além de aumentar a probabilidade de lesões.

         Outro fator importante é a possibilidade de realizar saques com efeito. O manuseio da raquete com a empunhadura continental da muito mais liberdade de movimentar o punho no momento do saque, possibilitando rebater com raquete na bola em diferentes ângulos. A partir do contato bola-raquete em outros ângulos surge o saque com efeito. Já os jogadores que manuseiam a raquete com empunhadura incorreta perdem a liberdade de movimento do punho, restringindo a possibilidade do jogador de variar o saque.

             A grande dificuldade no aprendizado da empunhadura continental é segurar dessa maneira no início do aprendizado. Como comentei anteriormente, com essa empunhadura a utilização do punho é muito grande, e essa sobrecarga no punho gera perda de firmeza no momento do golpe. No entanto, conforme o estímulo por sacar com a empunhadura continental aumente, a região do punho vai ganhando mais resistência, diminuindo a falta de firmeza, além de ter aumento de potência considerável.

           A partir do segundo mês treinando com a empunhadura continental, a evolução do saque aumenta consideravelmente, tanto em aumento de potência quanto em geração de efeito. Sendo assim, sempre inicie o fundamento saque utilizando a empunhadura continental, pois os benefícios a longo prazo são enormes.

Traditional Techniques of Foot and Foot - Up -Back in the Sack Achievement in Tennis Field

The Booty is one of the most decisive in the final outcome foundations of a match for both amateurs as well as professionals players . However , just as the looting has enormous power during a match , the biomechanics of withdrawal is the most complex and difficult to be performed among all the essentials. For this reason , the training teams have given more importance to the plea withdrawal.

One of the most important aspects of the transfer is driving the legs . It is from the lower limbs that is generated to transfer the body to the ball . There are two different techniques for performing the transfer ( Figure 1 )

                   Figure 1 : Técinica Foot - Foot and back -up .            www.ludgerobraga.com

1. Foot -back ( feet apart ) : A technique that consists of maintaining the initial distance between the members .

2 . Foot -up ( feet together ) : the technique of the approximation of the lower limbs during the execution of the service .

Making a comparison between the two techniques when it comes to peak vertical force , ie, the upward momentum of the body can achieve , Foot -up technique has greater vertical force compared to the the Foot -back technique . Thus, the point of contact racket - ball puller will be added to the Foot -up technique.

With this feature biomechanics , we can direct certain technique for the player. Players with short stature may benefit from using the Foot -up technique. Because this technique to increase the vertical force , they can increase the height of the point of contact racket - ball, getting a better use for drawing .

However, it is important to note that these changes in the biomechanics of looting take some time to have results . Also, the player needs to feel comfortable with the new technique . Many players have the facility to carry out some technical and other difficulties and should balance the extent to which this change can generate some benefit . If the player feels loose and move freely change is certainly welcome .

Important to note that these tips are for players who already have enough experience in the sport . Beginning players need to work other aspects of withdrawal initially , mainly an increase of the ball and coordinated all segments of the body work on the serve motion.

Backhand with one or two hands , which to choose?

When a student starts in tennis , in addition to learning all the basics , you need to choose how you want to learn the backhand (left for righties ) . There are two ways to perform the backhand they are , with one hand or with two hands . To help you choose , will be discussed the main advantages and disadvantages of both.

Backhand with one hand : The main advantages of this style are the sensation of striking a more " loose " form the ball , hit it with relative ease in slice and greater reach on the ball if it is compared with the two-handed backhand . Have the main disadvantages is the lack of firmness to return very fast balls , especially in returns of serve, the fact can not back the coup and the difficulty in hitting high balls .

Backhand with two hands: The main advantages of this style are the strongest to swing too fast balls , especially on returns of serve, the aid of non- dominant hand , mainly helping to compensate when a pass bounce and ease in hitting high balls . Have the main disadvantages are the feeling of being " stuck " during the performance of the coup to be using the non-dominant arm during the strike , strike with some difficulty and slice smaller range on the ball if it is compared with the one-handed backhand , having to intensify the leg work to always be near the ball.

As previously mentioned , both the backhand with one or two hands has its advantages and disadvantages . Not a criterion for choosing a style or another there . I think that the most relevant factor is that style feels more comfortable .

However , the student can follow a few tips to help you with your choice. Most adult men choose the backhand with one hand , because almost everyone feels looser , with freer movement while performing the blow. The women end up having preference for two-handed backhand because they feel much more strongly at the time of the coup , managing to generate more power . Very high and low mobility people have a preference for one-handed backhand by difficulty moving around the court .

Important to note that many practitioners tennis swap style quite frequently , not getting any developments in the forms . Search definitively choose the style that suits you and believe in it , especially when you're going through a bad phase , because that is when the change occurs from one style to another.

Rises to network, how and when to go ?

Currently , the network game is one of the least trained by practicing tennis. The fact that most professional athletes spend most of their time in the know during their matches online , does the amateur player to have less and less reference to go to the network , hampering the development in this very important aspect of tennis.

To have a good advantage in the network , one must , in addition to an improved technique, a good finish on the network , which we call " approach" . Approach means ball approach, ie , the ball will bounce and you then go to the network . To do a good approach , one must know how and when you get to the network because the transition between the baseline and the network is as important as the coup itself.

First you must know the ideal time to make a approach . To facilitate the understanding is necessary to divide the block into three major parts . The 1st part is between the network and a little behind the service line, the 2nd part will be between the end of the 1st part to two meters before the baseline , and the 3rd part is between the end of the 2nd part to the end of the baseline. Batting the balls that bounce the opponent in 3rd part is the least recommended to make an approach . As the ball bounces with a lot of depth , it hit the ball and try to get the network probably will not have time to even get to the service line , and therefore make it very difficult to conduct some groundwork on the network , greatly increasing the probability of error . Have the balls that bounce in the 2nd part of the court , are recommended in some circumstances . You need a good analysis of the height , effect and speed of the ball . When they arrive with too much speed or too high due to the topspin effect , are not so recommended to make an approach , due to the difficulty that the ball arrives . However, when the ball lands in this area , but with little speed and with little effect , can be a good option to climb. Have the balls that bounce in the 1st part of the court, but these are the obligation of the player using them to make an approach , it will have sufficient time to hit the ball and climb with ease to finish the point if necessary.

With this concept in mind , we can now move to the second tip . When performing approach , there is the option of directing them in cross or parallel . First , remember that every time you climb the network , you should follow the trajectory of the ball is hit , that is , if you play the ball cross , must follow the ball move toward the cross , paying for the same parallel . When the balls are directed to the cross , the time to reach the network will be higher , reducing the time to get to the network , as well as opening more angle to the opponent . Already, when the balls are directed in parallel , arrival to the network will be faster , as well as closing any angle parallel , leaving only a space to cross the opponent to play the ball , decreasing the angles of the court . Thus , we can conclude that when carry out a approach , try using the balls in parallel , because theoretically , it increases the probability of winning the points along the network .

The last point to be discussed , and one of the most important on the network increases , is that often these theoretical bases are not reflected in practice, and often they need to be changed . An example of this are the players who are going high and deep balls to the other side of the block just waiting for the opponent to err . Many of them are completely vulnerable when your opponent goes to network. Thus, even when an opponent to play deep balls , you can choose to climb the network , while not in a good position , because the simple fact of being there already destabilizes the opponent . Another important point is the fact that many players have much better forehand than backhand or vice versa . When climbing on the network , if the following theory , the best choice is to drive the ball in parallel , but this will also depend on whether the ball is falling at best or worst blow the opponent . Sometimes it is worth making a cross in the approach , but directing to blow the opponent weaker than insist on an approach in parallel , but in directing his best shot .

This leads us to think that even with a good tactical basis, there is no magic formula . Reading the game as a whole , since the basic tactics to understanding the opponent , are paramount to success in the network .

Coaching the fundamentals of network " Hilt of volleys "

It is increasingly frequent difficulty of practicing tennis in running scams on the net , both with the smash volleys . With the evolution of materials , which have dramatically increased the power in coups , and improve the physical capacity of athletes that made them faster and stronger , made ​​the game become much faster . Thus , the difficulty of reaching the network was growing , forcing players to spend most of the time at baseline during matches . This is a major reason to see fewer and fewer athletes go to network during their matches .

Based on this logic, the practitioners of shoes that are starting in the sport end up seeing their idols just hit hit the baseline . When will they train , end up trying to emulate their idols , only practicing the blows from the baseline . This makes the blows of the network are not nearly trained compared with baseline strokes , very limited development practitioners .

The climbs the network are extremely important player in learning , enabling a very wide range of alternatives for the matches . But for that to happen , it takes more time to train blows on the network . In this article, we will discuss the volleys left and right .

 First we need to divide the fundamentals of networking , where volleys at two points . One is the transfer of base line to the network, which requires proper positioning so that it can perform a good hit. The other is the mechanics of the coup itself. In this article , I will comment on the mechanics of the coup , especially the correct grip for the achievement of volleys .

To make the fundamentals of tennis , we use various grips . When we perform volleys , the most recommended is the continental grip . ( See Figure 1). The Continental grip is the same one used to perform the service, the smach and slice .

                                     Figure 1                         www.uniaosh.com.br

An important aspect to be emphasized is that , unlike the baseline strokes , volleys right and left are insured with the same grip . It is not necessary to turn the handle , because of issues which I will comment below.

One might think that the tip of the handle is simple and easy to perform, but there is great difficulty in practicing tennis on hold this way . They spend most of the time at baseline , hitting blows forhand ( right) and backhand ( left) , and virtually all exchange the handle from right to left and vice versa , as the grip of the right and left is different . Consequently , they end up creating a " good addiction " where changing the grip to make the blows from the baseline . When they go to the network , eventually turning the handle without realizing it , making the training with the Continental grip . But what's the point of not being able to turn the handle from one side to the other and because the Continental grip is the most efficient? First, when you arrive to the network , the distance between you and your opponent drops almost half, with it , the ball will come much faster the player . If you try to turn the handle, often do not have time and will delay the coup (contact ball / racket behind the body ) . And already anticipating for the next articles, contact ball / racquet on volleys is always ahead of the body . Have the reason for holding the racquet with a Continental grip is that with this grip your racket is more perpendicular to the ground , especially when the racket is a little further away from the body. If your racket is with the head pointed just slightly to the ground , probably at the time of your ball will be bounced on the network . Also, when the ball is low difficulty will be even greater , because the racquet head should be pointing slightly upwards. To compensate for this incorrect grip without realizing you rotate your wrist and forearm , but loses firmness hit by sudden movement in the wrist and forearm , leading to the blow error.

Another problem that occurs with the change of the grip is the lack of firmness on contact ball / racket . The Continental grip makes you work much with his fist. He must always be firm so that the racquet does not vibrate at hand and not completely lose control over the ball . People who change the grip usually does not have the muscles of the forearm region and strong enough grip to handle the impact of the ball . This takes time, average 2-3 months to allow the muscles in this region earn a little endurance and muscle strength , then yes, the evolution of volleys being most notable .

Do not forget , these tips are welcome when practiced . But to be charged in addition to the training that teachers spend , it is necessary that during the games in clubs and gyms with friends , you try going to the network whenever possible, because to have a good volley , you need, plus a good stroke mechanics , a good finish to the network , which will be the subject of the next article on volleys .

The importance of muscle strengthening on the forearm for tennis players of field

Comparing data between the number of people starting to play tennis and the number of dropouts who entered these people would probably have a very small number of dropout . It appears that people linger for many years practicing tennis. Consequently , the evolution of the student is confused by the improvement of motor coordination , and increased muscular endurance and strength of the muscles worked , generating ever more power in coups . However , as his punches are becoming more coordinated , faster and stronger , the overhead this musculature has just progressively increasing . This overload creates an increased possibility of inflammation in regions of the body over worked in tennis .

One of the areas is worked forearm . It has direct participation in all tennis strokes . An overload of this area , due to an excessive number of repetitions of strokes and realization of incorrect movements , increases the possibility of tendonitis in the elbow , the famous tennis- elbow , and loss of power in coups . Furthermore, as the shoe is a one-sided sports field , that is , it uses one side of the body more than the other, a muscle imbalance exists between the two forearms.

To prevent these possible disorders , weight training ( resistance training ) should be performed in conjunction with tennis lessons . Adherence by strengthening from the players is very small , and when there is any player who is strengthening , they often give preference to other muscle groups of the forearm and forget . Only 10 minutes is sufficient to work the muscles of the forearm . Even if not in a bodybuilding gym , you can train at home or before class tennis . A weight in each hand and a bit of will and dedication , is enough for you to train .

Then follows two basic exercises to work the muscles of the forearm:

As we can see , if we dedicate 10 minutes, 2 times a week to do these two exercises can prevent possible injuries resulting from training , plus get muscular endurance . A suggested practice is to perform 3 sets of 12 to 15 repetitions for each exercise . If you are not in a place with weights , use your creativity . Take some object with a consistent weight and do the same motion , as if holding the bar .

These exercises are basic , mainly dedicated to players who do not do any type of strengthening . If you can, seek the advice of a skilled physical education in the area and make a more complete workout .

Play and Stay

Some time ago , this widespread on the tennis courts around the world a new methodology of teaching tennis field for children . The program called Play and Stay , which means play and stay , aims to facilitate children's learning through tailored materials .

The balls used have little pressure , and they end up getting slower and with lower quick . This facilitates the exchange of passes over the points , plus the children have more time to perform the movements . However , I think the most important factor is the height of the ball quick . These balls bounce lower , hence lower children bounce balls , many of them at the waist , which greatly enhances the movement as remembered by tennis teachers , " bottom-up " . If children would train with normal balls , most of the balls arrive at the time of the child's head , and movements almost always end up being made ​​from the top down , which is not recommended when you consider the pattern of movements of base blows .

The net height and size of the block are also adapted . The networks are lower , thus facilitating passage of the ball to the other side. The blocks are reduced with demarcations such as ribbons and bands , enhancing control over the ball . Games with less space and lower network increases the number of exchanges of the ball , making the games more exciting .

As we can see , the major focus of this methodology is to encourage children to participate in games since the first day of class , unlike the classical approach , which focuses on repeat for the refinement of the technique , making the often joyless workout.

When the child comes to the first class , the first question that one does is : When we play Uncle ? Stay and Play using the method we will no longer need to talk to our students , " you need to grow some more points to be able to play ." Instead encourage you to play from the first moment , stimulating various qualities together , which are the physical , technical, tactical , psychological and social qualities , accelerating the learning process of the child. In just a tennis class , we can enhance many aspects that govern the game of tennis , including :

·         Count the points ;

·         Positioning on court ;

·         Basic Tactics of the game ;

·         Decision making ;

·         Basics ;

·         Concentration .

With this repertoire of stimuli worked together, we can form the future more developed players , increasing the number of players fighting for the top positions against the best players in the world

The world of concentration during tennis matches

Mental training is one of the areas of greatest influence on the outcome of a match , besides being one of the most difficult to be worked by the player .

Among various existing sub - areas in mental training , concentration is one of the most important resources during a match .

When using the concentration in its favor , the simple gesture of the player to be focused on the present, to the point that he's playing at the moment , the chances of winning a match greatly increase .

However , our mind becomes absorbed in the world of " up " very easily , such as : And " if" we lose that game ? " If " the judge had not stolen the ball last would win the game .

During a game , the player is often concentrated in the past , complaining the point that lost the previous game , or the lost chance to break the opponent's serve . Little does he know that because complaining of being let out of the points that probably will also miss the next , for the simple reason of not being focused on the point that this playing . Clearly , it's no use going back in time to complain of lived events , whether good or bad .

Similarly , how many times you were not at the end of the first set already thinking about the second, or that game that was 40-0 in his favor , but his mind was already on the next game , and when you realize that game that was 40 to 0 was rapidly to 40-40 . This dispersion for the future is to bring many players face to be focused on the following points without winning the primary , which is the point that is happening at the moment .

One can see that , and managed to keep the concentration in the present, and focus on the perception now , the performance during the games will be considerably better . Through the training of concentration , these goals can be achieved in a short time . Always think in this , point by point . Forget what happened or what you think will happen during the game and play every point as if it were your last .
