1 Optimization Framework on the Influence of New Rules of Beach Volleyball on Technical and Tactical Training Qiang Wang Institute of Competitive Sports of Shandong Sport University, Jinan , Shandong, China Abstract The basic goal of modern beach volleyball training is to improve the tactics and athletes' physical fitness in the game. In this paper, the author analyzes the optimization framework on the influence of new rules of beach volleyball on technical and tactical training. The implementation of the new rules not only accelerates the practicality and variability of the sand platoon tactics, but also forms a relatively complete competition system. In the competition, we should emphasize the overall cooperation and give full play to each player's specialty, to give full play to the collective advantage. Therefore, to sum up the targeted training methods and improve training means is an important way to promote the level of our country's sand platoon technology and tactics. Keywords: Dynamic analysis, Physical fitness level, Beach volleyball, Optimal path 1. INTRODUCTION After years of exploration and summary, China has a comprehensive understanding of the winning factors in the sand row competition, such as the attack speed, attack height, attack rhythm, attack point, surface change, comprehensive defense and other factors. But with the implementation of the new rules, sand platoon technology and tactics are constantly enriched and improved, force, skillful, change, fast become the new connotation of sand platoon competition rule. Gradually expand the winning factor group, we need to deepen the study of sand platoon technology and tactics development rules, for the development of training strategies, improve the level of competition to provide the basis. Sand row competition is affected by the quality of sandy land. The sandy ground is soft, flowing sand, athletes in the sand when the center of gravity is stable; in addition due to the buffering effect of sand impact velocity; and the sun, wind, and unpredictable factors such as climate change, making the sand row competition tactics and indoor technology has the obvious difference. At the same time, the open environment of Sha Pai competition provides the possibility for enriching the types of tactics and techniques, and also creates conditions for the application of technology. We observed that a large number of practical technology through the competition performance, especially some high and new technology, difficult, insurance by athletes skillfully, concise, practical features make sand row technology has been fully reflected in the match. The implementation of the new rules, especially the site area, on the offensive, technical movement restrictions in terms of lob, prompted the offensive batting technique athletes to be more standardized, more delicate, more practical. In addition, the new rules also encourage athletes to use sand row technology according to changes in the natural environment, requiring athletes to master the unique ability to control the ball and batting skills. For some informal technology, indoors may rarely appear, or not recognized, but in the sand row competition, but it is necessary and reasonable. Under the guidance of the new rules, the competition of sand platoon competition is increasingly fierce. All kinds of tactics combination and use in the search for a more effective way, the overall tactical system in a comprehensive, fast paced, changing, according to the different level of the opponent with concise and effective tactics has become an important means of winning. According to our observation, some practical techniques and tactics, especially some techniques with covert action, low demand and good batting effect, have been widely adopted in the sand platoon competition. 2. RESEARCH ON RHYTHM CONTROL The implementation of the new rules of each-serve-a-point rule, which is decided by the player's position responsibilities, a clear division of offensive and defensive tactics, has not been able to meet the requirements of the rapid conversion of offense and defense. It leads us to understand and understand the balance of attack and defense is not limited to the balance of players' distribution, but the simultaneous growth and balance of offensive and defensive forces. Specifically, in the competition, each player should have the dual function of attack and defense, especially with the strength of blocking and attacking on the net. With the frequent transformation of attack and defense rhythm, athletes are required to have the sense of contingency and autonomous tactics coordination. Counter, two players with independent anti blocking consciousness is further strengthened, and anti blocking, and prevent, and quickly cross run defense cooperation, strive for the composition in the tactical initiative has. Under the condition of changing environmental conditions, athletes should finish the attack with high quality, change the form of cooperation actively, make use of all the favorable 486

2 factors and cooperate flexibly, so as to achieve the goal of winning. The implementation of the new rules highlights the division of labor and cooperation in the game, thus promoting the dynamic balance of the offensive and defensive in the process of competition. Variety is the most vigorous tactical performance characteristic in the modern sand platoon competition, especially after the implementation of the new rules, the service tactics have been vigorously jumped. A net hanging light; offensive tactics have breakthrough colliers big storm, running attack and there are changes in the placement shot. On the premise of strengthening network defense tactics before the next block, the cross between the responsibility of the team members, flexible conversion of offensive and defensive role, according to the opponent's attack (blocking) of the situation to determine the flexibility to transform the defense organization form. The new rule makes the offensive and defensive duty division of sand platoon team intersect. The responsibility of the players has changed from a single attack or defense to an existing offense and a defense, with the ability to not only participate in attack, but also actively put into defense. Athletes are required to improvise and skillfully use various tactical means to complete the tactical plan of the party. The variety of tactics promotes the intensity of sand platoon competition and enriches the content. Figure 1. Beach Volleyball The future competition requires more comprehensive athletes, and only the single skill players can not adapt to the needs of the modern sand row competition. At the same time, the expansion and cross of the field duties require the athletes to get rid of the limitation of position division, making the changeable tactics play possible, and laying the foundation for organizing effective defensive counterattack. The composition of modern sand platoon tactics is not limited to the division of labor and responsibilities of the players, but also considers the offensive and defensive cross-functional and effective range of attack. Loose sand is not conducive to the movement of athletes on the field. This characteristic determines that athletes must control the speed and height of the ball, the speed is too fast, the height is not enough, it is difficult to form effective tactical coordination. On the contrary, it may cause a passive situation. Therefore, the pursuit of low arc medium speed rhythm trend appears in the sand platoon competition. Figure 2. Beach volleyball tactics 487

3 According to our observation, it is still a tactic adopted by the world's top teams and China's excellent sand queues to complete the offensive coordination with lower flight radian and medium speed. In fact, emphasis is placed on the low and medium speed of sand platoon technique and tactics, which is the specific embodiment of quick movement, quick adjustment, quick coordination and fast defence. Keep between the players with Benmosche and skilled, assist and take the initiative to compensate for the lack of peer play advantage. Focus on the control of the rhythm of the game, so that the composition of the tactics based on cooperation. Keep low arc, medium speed, smooth and effective, so as to master the initiative on the game field. Beach volleyball net is skill sport, but the importance of physical training has become increasingly prominent, technology is important, but good physical fitness can make up for the lack of technology, play physical difference affects technology. The implementation of the new rules requires that the training of sand platoon should be aimed at developing and improving the skills, tactics and comprehensive physical training in the competition. At the same time, pay attention to athletes will quality training, the direct impact in key order, not afraid of mistakes, don't hesitate to score the key, not affected by environmental change, their firm will overcome difficulties and boost morale, to strive for the victory of the match. 3. ANALYSIS OF SCORING FACTORS IN BEACH VOLLEYBALL Smash is the main means of scoring, reflects the level of attack and defense of offensive players in the game are constrained, a high success rate of spike attack can guarantee stability, if the game counter level, smash attack success rate level has become the determining factor determines the outcome of the game. The other part of the spike score counterattack spike, is the key to determine the anti anti successful, modern sand row competition in attack and defense is still stronger than prevention, so the importance of spiking score is self-evident. From the technical statistics can be seen, whether it is local or victory, spiking scores are ranked in the first place, accounting for more than half the proportion score. Attack is the main means of volleyball scores, it reflects the strength of the team, scoring game is to win their own foundation, from a technical analysis of the attack and the difficulty, from the point of view of defense, is the first smash scoring skills. Because spike technique is in the online fight hand to hand with the competition, athletes, due to size and jumping increase, and spiking skills and methods of changing, making it more difficult to deal with. Figure 3.Spiking skills The beach volleyball in the tap, pat skills difficult than spiking low, psychological pressure will increase, if the score will give each other behind the defense pre sentenced to increase the difficulty of these skills in beach volleyball competition is extremely common means of scoring. Usually in the offensive side when smooth or not smooth, can use and try, by the way the ball two times can disrupt each other's rhythm, also can break the passive situation in the time attack is not smooth, can serve to disrupt each other the defensive lineup, satisfactory effect. Spiking score is the most important part of the initiative score in volleyball game, and its success rate is high and low, which directly determines the result of the game. Although the percentage of serving in the beach matches is low, the scoring rate is around, but it is a very important factor in the outcome of the game. Beach volleyball serve most of the jump serve technique, more difficult, one is the site than indoor volleyball in total length was reduced to two meters, the two is bouncing on the soft sand height and wind speed, wind direction and affected by sunlight and other uncertain factors, make the service into power is greatly 488

4 reduced, the error rate increased. In this contradiction and serve attack, to destroy the first attack on the other side to increase the attack force, the service can not only improve the scoring rate of the attack to destroy each other - to reduce the pressure, while the other's psychology will also be affected, will have the initiative. Therefore, we should not judge the importance of the score from the point of scoring, but ignore the important means and factors of scoring. In order to get the score directly or destroy each other's pass, most players try to increase the attack force, the result is a direct score increase at the same time, the error rate is greatly increased. Serving plays an important role in the beach volleyball match. Serving is the beginning of the first attack in the volleyball match, and the quality of serving directly affects the process and result of the match. Therefore, with the development of beach volleyball, serve training has become a very important part of training. Service can be divided into many forms, mainly divided into two ways. The overhand floater and jump serve, the overhand floater placement to control the ball more accurately, to serve more clearly, because the ball is fast, irregular and volleyball operation, will make certain difficulties to the opponent's ball, which occupy the advantages of competition. Although the service doesn't seem like a lot, it's the beginning of the game. Accurate and aggressive serve, not only can directly score or destroy the opponent's offensive tactics organization, but also can reduce the defensive pressure of the party, to create more powerful conditions for fighting against. Powerful serve can also boost morale, expand victories, disrupt the rhythm of the opponent, and exert greater psychological pressure on opponents. On the contrary, if the attack force is not strong or too many mistakes, not only cannot score or give each other offense difficult, but will increase the difficulty for the defense of the party, with a direct impact on the control of the game master, therefore, to strengthen the offensive and aggressive serve as an important feature of today's volleyball match the. Beach volleyball and indoor volleyball is different, beach volleyball is two people, the game environment is a beautiful beach, the sea breeze will serve by influence of the ball a little difficult to master, according to the wind speed, wind direction, the placement will be different, will also receive a certain degree of difficulty. Therefore, in order to gain the initiative of the game, the attack of the serve can also be combined with the wind direction, aiming at serving people and attacking the opponent's soft edge. 4. TECHNICAL TRAINING ANALYSIS The ball is a technology, which is very important and very demanding in beach volleyball, is a bridge offense, his relationship with the ball requires people to maintain a good, outgoing and can not rotate, hand to clear, a slight deviation could be found more easily batter, especially caused by wind and when it rains, mistakes. In training, it's time to take time out to ensure it, especially at the initial stage. The principle of "from static to dynamic, from easy to difficult" should be mastered. By adjusting pad more in the beach volleyball game, due to the passing of the more stringent requirements of the fast moving is not in place or pass but hard case with digging technique. To adjust a ball attack, especially by the wind or rain the game more, anti ball accounted for a greater proportion, in a game of attack, and the proportion of pass pad adjustable often than passing, which requires more attention in this aspect of training. In the action on the pad adjustment should be paid attention to in the small arms up to use when the body accompanied coordination force, small arms scooping action to reduce contact spherical small arm should be consistent with the direction of the dig, in order to improve the accuracy and stability. The quality of the cushion determines the quality of the attack, and the training of the pad should be combined with the passing practice. It is necessary to do the pad exercises at different points and different angles repeatedly so as to provide reliable guarantee for the attack. Figure 4.Technical training of beach volleyball 489

5 By the player in the end, two players serve, then pad adjustment practice. In this training, the server strengthens the serve and reduces the error, because the emphasis is on the adjustment. And serve, serve, is to combine with actual combat. The number of pads for each position should be adjusted. In the specified number of times, finish the ball at different positions, and then exchange with the server. Although the pad adjustment appears to be a very simple action, but its role in the game is quite large, is the basic score pad, moving slowly, lack of preparation, physical decline is possible in pad, so we need to solve through training. If there are no stable pad adjustment skills, plus a variety of environmental factors of beach volleyball, will directly affect the quality of a spike, increase the possibility of losing, causing the game to passive and out of control. Therefore, we should strengthen the training of pad adjustment, better seize the initiative in the game, restrict the opponent's play, and lay a solid foundation for the victory of the game. In the practice of indoor volleyball training, it is more applicable in the training of indoor volleyball, and it can also be used in the training of beach volleyball. Beach volleyball has no back and forth points, no offside provisions, two players can block, the back line players can also go to the net before blocking. Then we aim at this characteristic, to finish the ball, then participate in blocking intensified training. 5. CONCLUSION The implementation of the new rules not only accelerates the practicality, abundance and variety of the sand platoon tactics, but also forms a relatively complete system. In the competition, the emphasis on the overall coordination is one of the important means to play the role of each player and play a collective advantage. On this basis, the expansion of the responsibilities of members and cross, support each other, complement each other, has become the main way to improve the level of attack and defense, improve the offensive effect. Both offensive and defensive, prominent anti defensive, the pursuit of dynamic balance of attack and defense is still the new rules after the implementation of sand platoon technology and tactics development trend. It is the main characteristic of modern sand platoon tactics to advocate the practical, flexible and adventurous style, and keep the rhythm of low arc and medium speed. Therefore, as soon as possible to find out the targeted training laws, improve training means, is to promote our country sand platoon tactics level important way to improve. The basic goal of modern beach volleyball training should be to develop and improve the skills, tactics and physical fitness of athletes in competition. Especially after the implementation of the new rules, we should update the concept of sand platoon technical and tactical training, grasp the opportunity and way of scientific training. In different training stages, there should be comprehensive technical and tactical training and special physical training in the plan, which can improve the adaptability of athletes. In modern beach volleyball in sports competition, often behind, hard against adversity in the situation, coupled with the impact of the special conditions of the surrounding environment, the athletes' psychological function and quality will often become the key factor to win the final victory. Therefore, psychological function and determination of the quality of training should be run through the whole training process, allowing players to build a strong desire to win, the cultivation of self control ability in the game difficult situation, will incentive to stabilize the mental state, mining and mobilization potential function, improve the ability to cope with difficulties.
