INTRODUCTION

Badminton is one of the most popular sports in the world and highest participation rates in the world we have over 220 million people playing globally.[1]

Badminton is a racquet sport involving high levels of intermittent, repetitive physical activity these physical demand depends upon the type and the level of the game.

In this game we always see the high-intensity and intermittent actions which depends upon the speed, flexibility, agility, dynamic balance, explosive power, anaerobic and aerobic conditioning, and the ability to react and anticipate quickly.

Badminton game is requiring a specific physical conditioning in terms of motor and action controls; coordinative variables such as static or dynamic balance, and which they are essential motor demands in this sport.

 Therefore, badminton players need enough strength and a high level of dynamic balance during the rapid postural movements around the court.

Training with agility and balance enables players to move faster on the court and to change directions swiftly while maintaining control of their body.

Agility is a defined as rapid movement of the entire body with change in the velocity or direction in response to a stimulus, such as the shuttlecock which an opponent player has hit.

The change in velocity is the ability to accelerate and decelerate concurrent with a change in direction.

A large number of players participate at, national, and international level badminton competitions all over the world, badminton, despite being a safe sport, has an increased risk of injury in the players because of the high intensity of play. and the physiological and biomechanical demand of the game.

core has been defined such as it is the whole the trunk including all the muscles that cross the hip and shoulders.

The core strength is particularly important in sports because it provides “proximal stability for distal mobility”. The core muscles stabilize the spine and trunk during movements of lower and upper extremities such as jumping, running, and throwing.

core strengthening training is a form of training is to increase core musculature strength, endurance, and neuromuscular control.

Core strengthening exercises are a very important component of badminton training, which help to improve movement efficiency and enhances the performance of sports.

Core strengthening exercises appears that repeated activation of core musculature along with extremity movements helps to improve performance in the gameplay.

The core muscle strengthening may help to improve dynamic balance and muscle coordination in the lower and upper extremities, and also helps to reducing risk of injury and muscle imbalance.

Graded motor Control is defined as the process of initiating, directing, and grading purposeful voluntary movement. Shumway-Cook has defined graded motor control as the ability to regulate mechanisms essential to movement.

Inter-limb coordination is a crucial element of graded motor control, involves the interplay of segmental kinematics, joint dynamics, and muscle activity.

Thus, graded motor control plays important role in badminton players 

The previous study shows athlete may not be able to control graded motor core strength which may increases the risk of injury in intense game play.

Graded motor Control include the production of reflexive, automatic, adaptive, and voluntary movements and the performance of efficient, coordinated, goal-directed movement patterns.

The core muscles strength helps to improve muscle coordination between upper and lower extremities.

If athlete achieve proper level of graded motor control core strength, then it will enhance the performance in the game play.

Also graded motor control core strength is important for trunk stability in the intense and speedy game play.

Thus, this study aimed to determine the effect of graded motor control core exercise program on agility and dynamic balance among amateur badminton players.
