    Abstract:

    The purpose of this research is to investigate the effects of selected plyometric exercises on the agility, explosive power and speed of 21-17-year-old male badminton players.

    Research tests of 40 elite male players 17-21 years old were badminton players who were randomly divided into two equal groups called the experimental group (average body mass index 22.79±0.51 kg/m2, subcutaneous fat percentage 16.84±0.27%, average age: 19.25±1.29 years, average height: 175.55±0.03 cm and average weight: 70.12±2.94 kg). The experimental group performed plyometric exercises for 8 weeks and 3 sessions per week, and the control group performed only badminton exercises. Before and after the plyometric exercises, the subjects were given Sargent test, 9 x 4 m agility test and 36 m speed test. For statistical analysis, descriptive and inferential statistics of dependent and independent t-tests (p > 5.0) were used. The investigations carried out in this research showed that selected plyometric exercises had a significant effect on the agility, explosive power and speed of the subjects (5./.>p).

    Key words: agility, explosive power, speed, plyometrics

    -1 Introduction

    A more effective method of different training methods, especially for strength training. The speed and ultimate strength of athletes is plyometric exercises. which has found a special place among inter-athletes and strength trainers in recent decades. Achieving the goals of heroic sports is not possible without motivation, perseverance and spending time in hard and exhausting exercises and the guidance of knowledgeable coaches equipped with modern science and effective techniques. Athletes train with great interest for many years in order to refine the desired skills in their sports fields in terms of movement and mind, and bring themselves to the peak of sports preparation and be able to appear in the competition scenes with self-confidence (1,8). Understanding the capabilities to achieve better sports records has an increasing value and importance. Due to these scientific and practical researches, today's man has more abilities and has become faster and better than previous men. By taking advantage of different sciences and using scientific and practical experiences as well as the valuable researches that have been done, one can appear better in the fields of various sports competitions. Improvement in records and better performance of skills is a clear proof of this claim (2).

    Agility, explosive power and speed are undoubtedly one of the most effective and important factors in many sports skills. Sports such as basketball, volleyball, football, high altitude, badminton and so on. Examples of this type of sports performance. The athlete in the competition scene is constantly in a situation where he has to fight and compete against stronger teams, bigger sizes and faster speeds. This kind of change and transformation is a constant process, and therefore, the athlete and coach should prepare themselves for the current and future challenges by using the best scientific methods and training methods (1).

    In order to reach the maximum ability and performance, different training methods have been invented, each of which has characteristics and each of these training methods has a different effect on different athletes (2).

    Plyometric training methods in order to combine speed and Strength is designed in sports performances, which is inherently dependent on physical strength, and if it is used with scientific methods, it gives the athlete important features so that he can start performing movements and skills at a faster speed, change the direction suddenly, and get a proper movement acceleration in the shortest possible time. Plyometrics creates an accelerated, explosive and quick reaction movement (1). Exercises include any muscle exercise or exercise in which the muscle relaxant is also used. These reflexes occur when already stretched muscles contract.. If this stretch is accompanied by fast contraction, compared to other states of muscle contractions, it will cause more movement power (2). 1-2 Statement of the problem Exercise and body preparation programs are beneficial when they are designed in such a way as to increase the special physiological abilities required to perform a sport, skill and physical activity. Plyometric exercises are used by coaches and sports science researchers during the preparation of athletes. Several studies have shown that by performing plyometric exercises, some factors related to physical fitness can be developed and increased to a significant extent and in this way help to improve sports skills (41).

    For success in today's modern sports, there are factors, one of the most important of which is the innate talent of people, and identifying and discovering this talent in time and early is the most effective and important factor in contemporary sports.

    Many countries with the help of sports science and methods Specialization has made a lot of progress in the category of talent search, Eastern European countries such as Russia, East Germany, Hungary and China followed regular programs during the 1970s and 1980s in a scientific talent search system based on physiological, structural, physical fitness and skill criteria to discover talents in time and attract and cultivate them, and they were able to obtain a large number of international medals.

    Talent It is a process through which children and teenagers are selected for a sport based on the results of the test and personal characteristics so that they have a chance to succeed in that sport. Badminton Talent Search Center of China, as a role model and world champion in the field of badminton, first pays attention to the physical structure, physical-motor and psycho-motor factors. Badminton is a sport that today's competitions are held all year round, so a person must have high physical fitness to continue the activity, the most important factor for this is to have maximum oxygen consumption. The elite badminton athletes have the highest aerobic and anaerobic abilities compared to the beginner players, and there are significant differences in the physiological and physical characteristics of the national players and the professional players of the world. Modern or advanced badminton games require high mechanical capabilities such as: speed, strength, agility, explosive power, endurance, balance and proper flexibility.

    The most important aspect of physical fitness of players is speed. In the short period of time that constitutes a fast game, anaerobic metabolism is needed, while the acceptable capacity in the whole competition is aerobic endurance, despite these, strength, explosiveness, coordination and flexibility play a significant role in this sport. In advanced badminton, most of the players tend to play attacking and aggressive games, in which anaerobic performance is of particular importance.

    According to the definitions of agility, explosive power, speed and plyometric exercises, as well as the types of movements and skills of badminton players on the playground and the type of shots in this field, and the need to inform more coaches and athletes into more effective scientific categories, the researcher intends to improve the effects of plyometric exercises. to examine and study the agility, explosive power and speed of male players aged 21 to 17 years.

    In fact, there is a very important question whether doing plyometric exercises can increase some effective factors of physical fitness in badminton? The athlete investigated and studied and found out whether designing and performing plyometric exercises along with badminton exercises is useful and necessary in the training programs of the athletes of this sport? The competition of the champion is problematic and will waste time and money.
