Brief Summary:
This study is to explore the effects of unilateral bilateral and combined resistance training on the serve speed and accuracy of amateur youth tennis players in China The subjects were young male tennis players aged 16-20 years from four universities in Gansu Province
The experiment was divided into control group CG experiment group 1 EG1-unilateral group experiment group 2 EG2-bilateral group and experiment group 3 EG3-combined group Used to compare the effects of different forms of resistance training on serve speed and accuracy Previous studies have shown that unilateral and bilateral resistance training can effectively improve strength power and speed in athletes Speirs et al 2016 Davo Jimenez Solana 2018 there is still controversy when comparing the advantages and disadvantages of two forms of resistance training Ramirez-Campillo et al 2015 Donab and Wall The results of this study will be expected to be updated in 2022 Unilateral resistance training bilateral resistance training and combined unilateral and bilateral resistance training were used as intervention models in this study
Based on the literature review the training frequency of this experiment was arranged as 2 timesweek and the total training time was 6 weeks with a fixed duration of each training session Each training session lasted a maximum of 60 minutes In this experiment the interval between the two weekly training sessions was at least 24 h to prevent subjects from being in a fatigued state in the relevant muscle groups of the body and affecting the experimental level

Detailed Description:
backgrounds
Originally known as lawn tennis tennis originated in France and became official in England There is evidence that people participating in tennis can provide numerous health benefits Secondly tennis is a sport with anaerobic metabolism supplemented by high-intensity aerobic metabolism which means that tennis has a great demand for speed strength and other physical qualities However in recent years Chinas athletes have been in debt for a long time resulting in weak basic qualities and lack of special ability which restricts the development of Chinas athletes In order to achieve good sports performance the training method is very important In the case of adolescents where strength is gradually declining evidence suggests that the implementation of scientific resistance training under perfect supervision can help the development of physical fitness and athletic performance Secondly resistance training is mostly focused bilaterally and the advantage of unilateral resistance training is that it is superior to the BLD effect to improve strength than bilateral training Evidence suggests that isometric strength gains after unilateral resistance training are almost twice as high as those after bilateral resistance training
Problem statement
Strength levels in todays youth are declining and evidence suggests that traditional training in youth focuses on bilateral and ignores movement patterns and focuses on single joints resulting in low stroke power and poor speed in youth tennis players Existing tennis training has focused on bilateral resistance training or tennis-specific technique training but the results have not been significant Tennis serve is very important and it is the key to win in tennis matches Evidence shows that muscle strength and explosive power are significantly related to tennis serve Therefore it is important to focus on the effects of different resistance training on tennis serve Secondly unilateral training is in line with the sport-specific characteristics and compound resistance training is significant for strength as well as explosive power so these two training modalities are crucial for tennis To summarize the problem statement of this study there are three main problem statements firstly the importance of serve technique in tennis program secondly unilateral training is in line with the specific characteristics of unilateral movement of tennis serve and thirdly the importance of combined resistance training in tennis
Proposed solution Different forms of resistance training will provide different benefits to the athlete and the sport of tennis is consistent with unilateral movement in order to achieve better athletic performance as well as skill performance The researcher will perform the following manipulation
Provide different forms of resistance training unilateral bilateral and combined and observe the changes in the athletic performance of tennis players in terms of strength explosiveness flexibility and coordination
Provide different forms of resistance training unilateral bilateral and combined and observe the changes in the tennis players serve speed and serve accuracy
Literature review
This chapter provides detailed information on the relevant literature and contributes to a comprehensive understanding of the following areas 1 tennis serve characteristics 2 youth resistance training safety 3 resistance training programmes and guidelines 4 youth resistance training and sports performance 5 physical demands of the tennis serve 6 the importance of unilateral resistance training 7 the BLD effect of bilateral resistance training and 8 the validity of combined resistance training The literature review is concluded with a summary of the literature review
The work of this study and the outlook
In the available studies gains from unilateral resistance training and bilateral resistance training appear to produce relatively contradictory resultsAccording to the principle of specificity of training the structure pattern of training should imitate motor technique structure as much as possible For example tennis serving soccer shooting badminton spiking and other sports that are presented in the form of unilateral should be intervened by unilateral resistance trainingHowever bilateral resistance training programmes are widely used in existing studiesTherefore the aim of this study was to investigate the effect of unilateral and bilateral resistance training on tennis serve performance of a unilateral natureIn addition the benefits of unilateral and bilateral resistance training in exercise performance such as strength speed and explosive power are also different Studies have shown that unilateral resistance training is more beneficial for exercise performance in the unilateral exercise mode and bilateral resistance training is more beneficial for exercise performance in the bilateral exercise modeSome studies however have yielded conflicting results Gonzalo studied 22 male basketball players who completed unilateral and bilateral resistance training on Saturday and found that the unilateral group performed better in the bilateral CMJ than the bilateral group UL 374 42 VS 398 51 ES047 65 BL 389 53 VS 406 55 ES027 45In addition another study showed that unilateral and bilateral resistance training were equally effective in improving lower limb strength in athletes but there was no significant difference between the two groups BL75 45 VS 81 43 UL76 61 VS 83 51 p005In summary this study will further confirm the improvement of unilateral and bilateral resistance training in strength explosive power coordination and other sports performanceIn addition as unilateral resistance training or reduced stability in unilateral testing has the potential to sacrifice strength development this study will also focus on the effects of unilateral and bilateral resistance training on bilaterally dominant motor performance such as strength and explosiveness as well as unilateral pattern tennis serve performanceThis will address the occurrence of bilateral sets that are unfamiliar with unilateral training leading to the phenomenon of sacrificing strength to maintain stability
The phenomenon of migration of athletic performance such as strength and explosiveness in both uni- and multi-joint muscles has been confirmed by numerous studiesbut there is little research on the phenomenon of complex skill transferThis study will determine the effects of unilateral and bilateral resistance training on serving performance thereby determining if there is also cross-education in complex motor skill performanceIn addition many studies have focused on the effects of unilateral and bilateral resistance training on the lower limbs so this study will use the upper limb test as one of the indicatorsTennis serve is a complex movement involving multiple joint muscles which is a process of transforming potential energy stored in the lower limbs into kinetic energy generated in the upper limbs so the testing of upper and lower limb strength and explosive force indexes is particularly important
