  Objective Using the theory of sports biochemistry, we can better complete the formulation of the training plan, the evaluations of training effect and the athlete's fatigue status, the real-time monitoring of training intensity and training amount as well as the function level of athletes and the comprehensive evaluation of nutritional status. To provide some theoretical guidance for the daily training of Chinese hearing-impaired table tennis team and to gradually establish the biochemical monitoring model for the Chinese Deaf Table tennis team, this subject has applied biochemical index monitoring to this team. Methods 2.1 Research Object 8 Athletes (male 4 female 4) of the Chinese hearing-impaired table tennis team were studied. The average height, weight, and age were 174.3±5.1cm, 65.4±11.6kg, 23.5±4.9 years respectively.2.2 Research Methods 2.2.1 Literature To find out the energy-supplying and metabolic characteristics of table tennis as well as the modes to accelerate the recovery period of body fatigue, we have searched a variety of literature on this purpose. The investigation of athletes' nutrition regulation, physical training and rehabilitation and other related research results lays a good foundation for the implementation of the project. 2.2.2 Expert Interview This paper discusses the energy metabolism characteristics of the hearing-impaired table tennis players by discussing with the coaches, athletes and experts and scholars of the national Hearing Impairment project group. The evaluation index and standard of athlete's body function, the method of training load monitoring, the way of nutrition regulation, the means of fatigue recovery and the process of physical training were discussed. 3.2.3 Field Investigation From April, 20th, 2017 to July, 10th, 2017, two researchers have long been in the center of national table tennis training located at Zheng Ding, Hebei province, to complete training monitoring and research services. Results 3 Research Results Phlebotomizing 7 of the Chinese hearing-impaired table tennis players in June,2nd,2017 and June 7th, 2017 respectively, The blood samples were analyzed by the team of experts and researchers in the Sports Physiology and Biochemistry Laboratory in Beijing Sport University. Part of the results was shown below in table 1, table 2. (1) Training intensity monitoring Huang Mengping had a slightly higher creatine kinase, a slight decrease in testosterone, a slight rise in cortisol, a lower testosterone/cortisol value, as well as an insignificant reduction in body function than the previous time. She should focus on the recovery of her body condition after training. In general, the testosterone, cortisol and testosterone/cortisol level in this team is slightly higher than the last time, blood urea lower than the previous. Strengthening the monitoring of exercise and nutrition and continuing to maintain a high body synthesis ability are favorable to intense competition. The overall creatinine level decreased, whereas 4 members of the team had insignificantly high creatinine, especially for Huang Mengping who first had appeared high level of it. Although this condition was not too severe to focus on, we should strengthen the regulation of athlete muscle injury and protect their kidney functions. (2) Monitoring of endocrine system indicators Both males and females had higher testosterone synthesis capabilities. They should continue to take the nutritional supplements. The T/C ratio of Tian Jiping has escalated sharply, but it was lower than that of other players. We should pay attention to his training load and promote the recovery training. (3) Monitoring of Iron Metabolic Index Huang Mengping's hemoglobin value and RBC value have been slightly elevated this time. It is suggested that she should keep on to take nutritional supplements and strengthen aerobic endurance training. Hemoglobin for Wang Zhe and Lin Huan (slightly decreased this time) was higher than their counterparts. The ability to transport oxygen was excellent, and it is agreeable to keep on. They need to continue to maintain and promote the body's oxygen reserve capacity. At the same time, they can also upgrade their overall red blood cell levels. Men have seen a high level of hemoglobin and the number of red blood cells as well as robust capabilities of oxymoron reservation and transportation. It is recommended to enhance aerobic endurance training, mainly improving the aerobic capacity. The serum iron of Tian Jiping was promoted quickly. He needs to build up the amount of iron nutrient intake and support the body synthesis. The full iron metabolic indicators were normal, but Zhang Chaoyue and Lin Lin Huan have been seen the lack of the abilities to synthesis iron. So we need to pay attention to iron metabolism-related nutrition intake. In general, iron protein level and the capability to reserve iron have declined. It is recommended to take more iron nutrients, Especially for Shi Ce. (4) Food surveillance After the diet regulation, the indicators for the team's blood fat were within the normal range. Zhang Chaoyue and Wang Zhe should control the high-fat food intake, thus reducing the amount of low-density lipoprotein. (5) Surveillance of immune Indicators The white cell, blood cell classification and immunoglobulin (IgG, IgM, IgA) of the team are all normal, Wang Zhe’s immunoglobulin A and Xu You’s immunoglobulin M are slightly low, we should pay attention to protection. Conclusions  Through the overall monitoring and analysis of the biochemical indexes of the leading athletes of Chinese hearing-impaired table tennis team, The characteristics of biochemical indexes of the high-level hearing-impaired table tennis players are mastered. On the basis of the overall characteristics of the individual, we carried out personalized monitoring and evaluation to give coaches and athletes advice on training, rehabilitation and other aspects related to practice. Biochemical tracking in China's hearing-impaired table tennis team has achieved an excellent application results that have been unanimously recognized by the coaches and athletes.

The research is aimed at comparing the kinematics (the movement pattern in the most important joints and accelerations of the playing hand) between female table tennis players coached in Poland (POL) and China (CHIN) during the performance of a topspin backhand stroke (so-called quick topspin). The study involved six female table tennis players at a high sports skill level, playing in Poland’s highest league. Three were national team members of Poland (age: 20.3 ± 1.9 ), while the other three were players from China (age: 20.0 ± 0.0 ). Kinematics was measured using MR3 myoMuscle Master Edition system—inertial measurement unit (IMU) system. The participants performed one task of topspin backhand as a response to a topspin ball, repeated 15 times. Statistical parametric mapping (SPM) was calculated using SPM1D in a Python package that offered a high-level interface to SPM1D. The SPM method allowed for the determination of differences between the Chinese and Polish female athletes. The differences found are probably mainly due to differences in the training methodologies caused by different coaching systems. The observed differences include, among others, greater use of the so-called small steps in order to adapt and be ready during the back to ready position and backswing phases, which gives the CHIN players slightly better conditions for preparation for the next plays. The CHIN players’ position compared to that of the POL players favours a quicker transition from the backhand to the forehand play. This difference is probably related to the difference in the dominant playing styles of the groups studied. Despite the differences in movement patterns in both groups, the exact value of playing hand was achieved. This may be a manifestation of the phenomenon of equifinality and compensation. All the differences found are probably mainly due to differences in the training methodologies caused by different coaching systems.

The main feature of the period of participation in tournaments is the need to maintain a specific level of special ability. Therefore, the specifics of physical training has an applied-functional nature to high-level loads. Its purpose is to ensure maximum special training and maintain its level, as well as maintaining general training. Aim. Determining the features of physical training of young tennis players for competitions. Research methods: analysis of scientific and methodological sources; observation; measurement and accounting; instrumental techniques; statistical analysis. Results. In the process of ascertaining experiment, the current level of physical and technical readiness of young tennis players was determined a week before the start of participation in tournaments. In the process of formative experiment, the effectiveness of the developed set of physical training exercises was determined, which was used directly during the participation of young tennis players in tennis tournaments, which had a training (simulation) character and were held on the basis of the club and other clubs. Conclusions. The obtained data partially testify in favor of application of the developed methodical complexes for physical training of young players during competitions. Requires a more detailed study of the selection of test exercises to assess young tennis players during participation in competitions. The use of the developed complexes only partially affected the dynamics of the strength abilities of the legs and shoulder girdle. The temp of blows also did not change significantly, but the complexes did not contain specific exercises to improve it. Thus, the presented complexes are promising for use for physical training of tennis players during participation in competitions, but require more thorough testing efficiency.

Abstract The paper presents results of empirical study on elite foreign athletes working in Polish top table tennis clubs. It focuses on professional migration motives of elite table tennis players. In-depth interviews were carried out with 27 foreign table tennis players from 10 countries, who were playing for two top league clubs in Poland, and with 8 club coaches who were working with foreign players. Research was conducted during the 2014/2015 league season. The surveyed athletes came both from European countries of higher economic status than Poland and from outside Europe, from countries of lower economic status. A significant number of the surveyed players (11) arrived at Poland from China. The reasons why the surveyed players decided to come to Poland were varied and included both pull factors resulting from attractiveness of work abroad and factors pushing the players away from their home country sport system. Among the motives mentioned by the respondents, the major ones seem to be the desire to continue their professional career and to develop as players. Most of the respondents reported a few factors motivating them to come to Poland and play in the Polish table tennis league. Most often they gave several reasons altogether and it is not easy to classify them as exclusively one of the typo-logies of sport migrants presented in the literature. For some of the respondents, the decisive criterion was the high level of the Polish table tennis league, staying only slightly behind the French and German leagues. For others, good financial conditions offered by the Polish clubs and the possibility of improving living conditions were of key importance. Push factors were particularly important in the case of Asian players representing a very high level of sport skills, however slightly lower than the level of the Chinese national team.

Objective Research purpose: This research aims at giving an comprehensive summary of the current situation of physical training of Chinese ice hockey team and helps to grasping the key points of their physical training, innovating the specific training methods, and improving the competitive performance of sports teams. Methods Research methods: “Literature research” is the main method of this research. The authors have consulted CNKI, WWW, Wiper net, Knowledge Base of Sports Resources, EBSCO host and some other databases and analyzed 45 valuable articles in total. Results Research result: The research results can be analyzed from three aspects--physical stamina requirement of players, training theories or methods, and physical fitness evaluation of players. 1 Physical stamina requirement of players Ice hockey is an aperiodic sport with a repeated alternately of high, medium and low intensity, which is characterized by intermittent high intensity exercise and high antagonism. The sports’ mode is 70: 2: 30, which means players have 70 seconds to play and two minutes to rest each time, and the whole match will take 30 minutes. The blood urea, creatine kinase and serum testosterone of players will significantly change after the competition. Most of their heart rate will be above 70 percent of the maximum rate and some athletes’ blood lactic acid value will reach to 17.1 mmol / L. Therefore physical stamina training is necessary for them. 2 Training theories or methods 2.1 Characteristics of physical training load and periodicity Athletes’ physical training presents periodic changes. Specifically, their competitive state presents a pattern of formation, maintenance and temporarily fading with the change of training load. According to the theory of cycle and the principle of competitive sports training, some domestic researchers have established an annual cyclical training structure for the national women hockey team, and have achieved ideal results in practice. The annual cyclical training structure consists of 5 levels, 3 periods, 7 phases, 9 middle cycles and several different types of small cycles. In preparation for the 21st Vancouver Winter Olympics, the national women hockey team have accepted 482.5 hours physical training , accounting for 47 percent of the total training volume. 2.2 Strength quality The special strength of ice hockey consists of maximum strength, speed strength and endurance strength. Both land and ice strength training  are included, which have their own advantages and disadvantages. During the preparation period, Canadian fast strength training method, which is a kind of land strength training, can be used in general strength training stage, and the combination of land and ice training methods can be adopted in special strength training stage. And the method of simulating competition scene with the combination of special tactics is usually needed for the purpose of developing special strength. Step compression, impact exercise, waist load and skate weighting can effectively enhance the special strength while hooting strength requires special training methods. 2.3 Speed quality The speed of ice hockey include “simple and complex reaction speed”, “thinking process speed”, “starting speed”, “paragraph speed”, “fast braking of action”, “fast completion of technical action and convergence speed of action”. Therefore speed training should strictly control the training mode, frequency, interval time, and the stability of speed and the mechanism of energy metabolism system should be considered firstly. The usually methods are: repeated training, speed changing training, race and game training. 2.4 Endurance quality The endurance quality of hockey athletes consists of general endurance and special endurance quality. The general endurance training mainly needs aerobic methods, while the specific endurance training includes aerobic and anaerobic mixed training, anaerobic phosphate training and anaerobic glycolysis training. Endurance training is carried out at all stages of the season and both ice training and land training are needed. Methods of developing general endurance include uniform running, intermittent running, fartleke running, swimming and ball games. 3 Assessment and diagnostic methods of ice hockey player The physical fitness of athletes is mainly monitored by testing method, which mainly tests general physical fitness and special physical fitness, and such tests are carried out at different stages. There are also researchers on the physical characteristics of athletes in aspects of the body shape, function and quality . Conclusions  Research conclusion:The purpose of ice hockey physical training is to improve sports performance, enhance energy supply ability of metabolic system, and reduce injury. Such training should accord with its special characteristics and adopt the periodic training structure arrangement. And also should focus on the strength, speed, endurance, reasonable proportion of training arrangement on ice and land. The current physical fitness evaluation which includes general and special physical fitness still needs further study.
