The Plyometric Training In Badminton

The Plyometric Training In BadmintonPHYSICAL TRAINING IN SPORTS sensual fitness is a actually important factor affecting performance in sports. As in the preparative phase of periodization plan for any preparation course of instructionme, the somatogenic fitness is always the first to be create before focusing into other cooking factors much(prenominal) as technical training, tactical training, and psychological training. Physical fitness contributes to sports performance. It serves as a lay outation that use ups to postgraduate performance level in sports (Bompa Haff, 2009).Many researchers imbibe studied various types of physical fitness training, such as brace training (Myer, 2005 Myer et al., 2006), agility training (milling machine et al., 2001 schoolboyish et al., 2001 Holmberg, 2009), sprinting training (Markovic et al., 2007), resistance training (Candow Burke, 2007 Sturgess Newton, 2008 Hamberg-van Reenen et al., 2009), circuit training (Chtara et al., 2008 Dun discharge et al., 2009), interval training, and plyometric training (Gehri et al., 1998 Swanik, 2002 Spurrs et al., 2003 Turner et al., 2003 Myer, 2005 milling machine et al., 2006 Myer et al., 2006 Saunders et al., 2006 Salonikidis Zafeiridis, 2008 Vescovi et al., 2008 de Villarreal et al., 2008 Meylan Malatesta, 2009 Thomas et al., 2009 Ebben et al., 2010 King Cipriani, 2010 Rubley et al., 2011) and many studies found that physical training served the purpose of improving various physical attributes, such as flexibility, functional performance, muscular control, muscular power, distance rail performance, running economy, effectuality performance, detonative power, vertical jump, initial acceleration, hurry, and agility (Gehri et al., 1998 Swanik, 2002 Spurrs et al., 2003 Turner et al., 2003 Kotzamanidis, 2006 Miller et al., 2006 Saunders et al., 2006 Markovic et al., 2007 Chtara et al., 2008 de Villarreal et al., 2008 Jullien et al., 2008 Salonikidis Zafeiridis, 2008 Vescovi et al., 2008 Meylan Malatesta, 2009 Thomas et al., 2009 Walklate et al., 2009 Sez-Sez de Villarreal et al., 2010).PHYSICAL TRAINING IN BADMINTONBadminton is a naughtyly competitive dynamic sport. At elite level, it is suggested that badminton is characterized by repetitive efforts of alactic nature and spacious intensity which argon continuously performed finishedout the match (Cabello Manrique Gonzlez-Badillo, 2003 Lees, 2003 Faude et al., 2007 Sturgess Newton, 2008). Badminton instrumentalists are ask to be able to light upon in multiple stresss duration smashing and receiving a shuttlecock at high speed. The speed of a shuttlecock rump be up to 421kph (Guinness World Record, 2009).Badminton players are often required to perform speed, agility, flexibility, endurance, and strength capabilities at their limit. It is proposed by Badminton Association of England (2002) that the off- address type of fitness training for badminton can include strength training, aer ophilic training, speed and agility training, flexibility training, core stability training, and circuit training.As an explosive sport, badminton performance can be conjure upd from resistance training. Effective resistance training programme requires a systematic work out of analysis, implementation and evaluation to ensure maximum adaptation and improvement. The prescription of resistance training methods can enhance badminton specific performance in jump smashes, lunges, and quick adjustment of advocate (Sturgess Newton, 2008).AGILITY IN SPORTS insouciance is an essential element for many sports. It is an ability that involves a rapid unit of measurement soundbox parkway with changes of direction or velocity in response to a stimulus. In many competitive sports such as badminton, the players do not perform at their own pace and melt down, but are performing in response to the shuttlecock, the opponent, or the partners. As such, agility in badminton is not completely an independent factor ( girlish et al., 2002 Sheppard preadolescent, 2006 Young Farrow, 2006 Jullien et al., 2008).Little and William (2005) proposed that agility is a specific physical attribute that is fundamentally important to sports performance for cardinal reasons. First, exploitation agility will provide a strong foundation for muscular control and repulse skill function, thereby establishing overall performance in badminton. Second, good agility enable players to move immobile in balanced and stabled manner, and this proper faeces mechanics and this may reduce injury risk. Finally, as an suspensor matures, a heightened ability to quickly change directions will enhance overall performance in twain proactive offensive and unstable defensive circumstances.According to Young and Farrow (2006) and Vescovi (2008), agility is important as many sports such as badminton performed on a court require high-speed total body deeds. Many of these movements are in response to the motion of the shuttlecock, opponents, or partner. As such, quick movements are very important.Deterministic Model Of Agility PerformanceThe multifactorial nature of agility has been represented by a deterministic pattern in Figure 2.1 which indicating the various factors contributing to performance in sports include badminton (Young et al., 2002). The model (Figure 2.1) indicated the agility can be affected by perceptual and decision fashioning factor, and change of direction speed.Perceptual and decision making is one of the main factors affecting agility. The factors affecting perceptual and decision making included visual scanning, anticipating, pattern recognition, and knowledge of the condition.Leg muscle qualitiesChange of directional speedYoung and Farrow (2006) noted that agility is affected by the change of directional speed. Change of directional speed is influenced by the techniques, straight sprinting speed, and leg muscle property.Techniques to change direction and change velocity quickly are expected to be influenced by the mail service of the body while running. A forward lean is required to accelerate, a backward lean to decelerate and stop, and a sideward lean to produce a askant change of direction. These body inclines are necessary in order to produce forces to the ground to evoke answer forces in the desired direction. The technique of body lean enables badminton player to make quick adjustments of strides to accelerate and decelerate, to the running posture to execute a quick change of direction. Such quick adjustments of posture and smudgeing of limbs is clearly a skill that requires training. This can be developed by plyometric training (Meylan Malatesta, 2009).Leg muscles quality is all responsible for change of directional movements. The available research provides little support that leg muscle strength, power, and replyive strength are major contributors to agility performance. However, a rationale was made to suggest th at plyometric training program involving jumping exercises that contain single leg lateral takeoffs, such as bounding in a zag pattern could potentially be beneficial to change of directional speed development (Robinson Owens, 2004 Miller et al., 2006 Sheppard Young, 2006 Young Farrow, 2006 Markovic et al., 2007 Thomas et al., 2009). Good quality of leg muscle in badminton helps to reduce time taken from tack together position to move to receive a shot.AGILITY CONTRIBUTION IN BADMINTONMotion analysis of a typical badminton match reveals that there are many changes in direction and it requires the athlete to be very agile in all directions (Cabello Manrique Gonzlez-Badillo, 2003 Sturgess Newton, 2008). Notational analysis of European players during international tournaments indicated that badminton can be characterized by repetitive, short-duration, high-intensity efforts with high-frequency movement (Cabello Manrique Gonzlez-Badillo, 2003).Badminton is the fastest sport amon g the racket games with the speed of the shuttlecocks capable of travelling up to 421kph. This means in the court area of approximately 34m2 for badminton singles, the shuttlecock will take not more than 0.15 second to pass through the entire badminton court which is 13.4m in length (Olympics ABC, 2007). As a sport with such a high speed, agility plays a very important role to contribute to the performance.In an elite badminton match, the competition can be played up to more than 60 minutes, and the total running distance can be covered up to 6km. But the aptitude spent for both players were not the same. When a player is more agile and faster than opponent, he can get into affirmatory position to play the shot to move opponent around in the badminton court which will lead to greater radius of movement for the opponent. In another word, throughout the match, the player who defy better agility are having advantage and spending little effort and energy compare to the less agile o pponent.Olympic ABC (2007) also proposed that a player need approximately 0.32 to 0.36 second to move from a get up position towards the shuttle and approximately 0.486 seconds to react to the coming shot. This lead to an idea that a badminton player needs about 0.8 second to react to a shot and move to receive the shot. In this condition, agility is a critical factor affecting the performance. time taken to react to the coming shot is affecting by the perceptual and decision making factor, while the time taken to move from a ready position towards the shuttle is affecting by the agility, which have the direct relationship with the change of direction speed. Good agility and fast action to move from ready position enable a badminton player to return the shot in a favourable position and have advantage over opponent.PLYOMETRIC TRAINING IN IMPROVING AGILITYPlyometrics are training techniques utilize by athletes in all types of sports to increase strength and explosiveness (Chu, 199 8). Plyometric training programme involving jumping exercises that could potentially be beneficial to agility development (Robinson Owens, 2004 Miller et al., 2006 Young Farrow, 2006 Thomas et al., 2009).Plyometric drills usually involve stopping, starting, and changing directions of movement in an explosive manner. These movements are components that can contribute to developing agility (Young et al., 2001 Miller et al., 2001). Previous studies found that plyometric training, when used in a periodized manner, can contribute to agility gains (Miller et al., 2006 Thomas et al., 2009).Agility is an explosive movement which can be referred to running speed and changes of direction ability. Fast running speed and quick change of direction contribute to good agility. Explosiveness is affecting the running speed and change of direction ability. Thus, improvement in explosiveness leads to agility development. Plyometrics have been proven to be an effective method to improve on explosiven ess (Markovic et al., 2007 Chtara et al., 2008).By enhancing balance and control of body positions during movement, agility theoretically should improve (Miller et al., 2006 Young Farrow, 2006). Plyometric activities have been used in sports such as football, tennis, soccer or other sports event (Yap Brown, 2000 Robinson Owens, 2004). These sports are intermediate sports which require rapid whole body movement with changes of direction or velocity in response to a stimulus, which is similar to badminton. finishPhysical fitness is a very critical factor affecting sports performance. It contributes to sports as the foundation that leads to high performance level in sports. Plyometric is one of the physical training which leads to the gain of various physical attributes which included speed, power, and agility (Miller et al., 2006).In badminton, a player requires high-speed total body movements. Many of these movements are in response to the motion of the shuttlecock, opponents, or partner. Agility permits badminton player to start quickly and efficiently, move in the fall off direction, and to change direction or stop quickly to make a play in fast, smooth, efficient, and repeatable manner, in response to a stimulus.A competitive badminton match can be played up to more than 60 minutes, agility allow a player to be in the favourable position quickly to play the shot to move opponent around in the badminton court which will lead to greater radius of movement for the opponent. In another word, agility leads to the advantage of lesser effort and energy spent than the less agile player (Olympic ABC, 2007).Young and Farrow (2006) noted that agility is affected by change of directional speed. Quality of leg muscles is exclusively responsible for change of directional speed. Good quality of leg muscle and good agility in badminton helps to reduce time taken from ready position to move to receive a shot. This enables a badminton player to return the shot in a favou rable position and have advantage over the opponent.Agility refers to running speed and changes of direction in an explosive manner. Fast running speed and quick change of direction is the key to good agility, which is affected by explosiveness. Thus, improvement in explosiveness should lead to agility development. Plyometrics has been proven to be effective and efficient in developing explosiveness (Robinson Owens, 2004 Miller et al., 2006 Young Farrow, 2006 Markovic et al., 2007 Chtara et al., 2008 Thomas et al., 2009).Plyometric drills involve starting, stopping, and change of movement directions explosively. These movements contribute to agility development (Young et al., 2001 Miller et al., 2001). Previous studies showed that plyometric training, when used in a periodized manner, can contribute to agility gains (Miller et al., 2006 Thomas et al., 2009). In addition, plyometric training which enhances balance and body control during movement promotes improvement in agility (Mi ller et al., 2006 Young Farrow, 2006).
