How to Increase the Number of Maximums in Limited over Games

The game of cricket can be depicted just as a challenge between bowlers, who convey the ball, and batsmen who endeavour to score keeps running by hitting the ball. It can be broken down into four major phases: Stance & Backswing, Stride & Downswing to Impact at last Follow Through.

Batting in cricket requires an expansive scope of effective results. It is one of only a handful couple of games where the player can strike the ball in a 360⁰, which requires a wide and shifted collection of strokes (Marc R. Portus & Damian Farrow, 2011). Batting is a dynamic interceptive activity in which achievement is to a great extent dictated by a player’s capacity to use delivery information to choose and execute a fitting engine reaction. Interceptive activities can be characterized as remotely coordinated the direction of which is proposed to match with that of an ideal target (Button & Summers, 2002). Whiting (1969)sorted such activities as the most mind boggling of motor skills, whereby including undertaking imperatives require a ball to be gotten and sent away inside a similar development.

The Deterministic Model

The deterministic model presented here was primarily adapted from

Angular Velocity of Bat

Angular velocity describes how fast and in what direction a body is rotating (radians/sec).

It is important becausev = r ω; where v = linear velocity, ω = angular velocity, r = radius of rotation (arc length).  ω has a direct impact on v i.e.: the speed of the ball off the bat and thus displacement of ball. 

Stance:

Stance is the comfortable relaxed and balanced position with feet apart but parallel. It is important that the batter has a stable base, for a base to be stable the centre of mass is evenly distributed across both feet.

This is important for the initial movement because if your weight is on spread between both feet it enables the batter to move forward onto the front foot for a drive or move onto their back foot to play a cut or pull shot.

The correct grip and coupling between the bat and hand plays the vital role in cricket. Because players can improvise the grip to control the rebound velocity, this enables them to manipulate the ball into free areas on the ground and score runs.

It is determine that the top hand grip (left hand for right handed batsman and vice versa) is the dominate hand, with the bottom hand helping with the execution of the shot. This creates smaller moment of inertia providing more bat control (Adair, 1990; Bahill & Karnavas, 1989; Fleisig et al., 2002).Resulting in less stride time and increased bat quickness while not sacrificing a significant loss in bat velocity (the bat feels lighter).

If batters want to get their bats into the hitting zone more quickly, they need reduce the rotational inertia of the bat, making it easier to rotate the bat more quickly. That is, the batter must get a greater fraction of the bat closer to the axis of rotation or equivalently have less of the bat further away from the axis.

Coefficient of Restitution (COR)

COR is defined as the ratio of the relative speed of the objects after and before the collision            (Fisher et al., 2004). The COR is important in cricket as it enables the position of the sweet spot to be identified (Grant, 1998). Optimal COR enables greater ball displacement after impact – would enable the cricket ball to be hit further (increase no of 6’s).

The magnitude of COR alters with the impact location due to variation in the flexural stiffness (Grant, 1998) – higher flexibility of the bat means larger amounts of energy will be lost.

In cricket, the variation in the flexural stiffness is due to structure design (Fisher et al., 2004).

Fisher et al., (2004) found that the location of maximum COR occurs in a 4cm region (19-23cm from the toe of the bat).

Bats designed in a more traditional style with a mass which is evenly distributed across the whole of the blade = highest COR (Fisher et al., 2004). However, the structural design is not the only factor.

Maximum COR values are found when coupled with the rotational speed of the bat at impact as energy is transferred into the bat from the body – allowing for greater displacement of the ball.

COR can be linked with the stance and grip of the player as timing and anticipation are both involved in making contact at the highest COR. The ability to learn how to transfer weight (onto either front foot or back foot) allows for more precise timing of the ball on to the bat which would result in maximum COR.

Shots which come off the edge, toe or shoulder of the bat have little chance of reaching the boundary, meaning the ability to maximise COR is important in cricket ball striking.
