Bowling Performance Assessed with a Smart Cricket Ball: a Novel Way of Profiling Bowlers †
Proceedings Bowling Performance Assessed with a Smart Cricket Ball: A Novel Way of Profiling Bowlers † Franz Konstantin Fuss 1,*, Batdelger Doljin 1 and René E. D. Ferdinands 2 1 Smart Products Engineering Program, Centre for Design Innovation, Swinburne University of Technology, Melbourne 3122, Australia; [email protected] 2 Department of Exercise and Sports Science, Faculty of Health Sciences, University of Sydney, Sydney 2141, Australia; [email protected] * Correspondence: [email protected]; Tel.: +61-3-9214-6882 † Presented at the 13th conference of the International Sports Engineering Association, Online, 22–26 June 2020. Published: 15 June 2020 Abstract: Profiling of spin bowlers is currently based on the assessment of translational velocity and spin rate (angular velocity). If two spin bowlers impart the same spin rate on the ball, but bowler A generates more spin rate than bowler B, then bowler A has a higher chance to be drafted, although bowler B has the potential to achieve the same spin rate, if the losses are minimized (e.g., by optimizing the bowler’s kinematics through training). We used a smart cricket ball for determining the spin rate and torque imparted on the ball at a high sampling frequency. The ratio of peak torque to maximum spin rate times 100 was used for determining the ‘spin bowling potential’. A ratio of greater than 1 has more potential to improve the spin rate. The spin bowling potential ranged from 0.77 to 1.42. Comparatively, the bowling potential in fast bowlers ranged from 1.46 to 1.95.

Musculoskeletal Modelling of the Shoulder During Cricket Bowling
MUSCULOSKELETAL MODELLING OF THE SHOULDER DURING CRICKET BOWLING Lomas Shiva Persad Department of Bioengineering Imperial College London A thesis submitted in fulfilment of the requirements for a degree of Doctor of Philosophy at Imperial College London and the Diploma of Imperial College January 2016 2 Abstract Shoulder injuries affect athletes who participate in overhead sports, such as swimming, baseball or basketball. This is due to the high loading, large range of motion and repetitive nature of the sporting task. Impingement has been identified as the most common cause of shoulder pain in overhead athletes. Cricket bowling involves one of the more complex sporting tasks where the arm goes through a large range of motion during circumduction to project the cricket ball at varying degrees of speed and spin where injury surveillance research estimates that over 20% of cricket injuries are related to the upper limb with the glenohumeral joint being the second most injured site. Similar to other overhead athletes, cricket bowlers have a prevalence of shoulder injury and pain with loss of internal rotation. It is hypothesised that this is due to large distraction forces and muscle imbalance at the glenohumeral joint. A second, specific hypothesis is that bowlers who have greater internal rotation after delivering the cricket ball are more likely to suffer from impingement. The motivation for this study is derived from these hypotheses. The aim of this thesis was to test the hypotheses above and investigate potential shoulder injury risk in cricket bowlers. A full body 3D kinematic analysis of fast and slow bowling actions was conducted and a musculoskeletal model used to investigate joint forces and muscle activations at the shoulder. -
Cricket Ball Aerodynamics: Myth Versus Science
i¸ ._ _' -_ .¢, Cricket Ball Aerodynamics: Myth Versus Science Rabindra D. Mehta Experimental Physics Branch, NASA Ames Research Center, California, USA ABSTRACT: Aerodynamics plays a prominent role in the flight of a cricket ball released by a bowler. The main interest is in the fact that the ball can follow a curved flight path that is not always under the control of the bowler. The basic aerodynamic principles responsible for the nonlinear flight or "swing" of a cricket ball were identified several years ago and many papers have been published on the subject. In the last 20 years or so, several experimental investigations have been conducted on cricket ball swing, which revealed the amount of attainable swing, and the parameters that affect it. A general overview of these findings is presented with emphasis on the concept of late swing and the effects of meteorological conditions on swing. In addition, the relatively new concept of "reverse" swing, how it can be achieved in practice and the role in it of bali "tampering", are discussed in detail. A discussion of the "white" cricket ball used in last year's World Cup, which supposedly possesses different swing properties compared to a conventional red ball, is also presented. _TRODUCTION The origins of cricket are obscured and a source of much speculation, but there is some evidence that it was played in England in thel300s. People who do not play cricket (the majority of the human race) know it as a game of childish simplicity. A pleasant game for the beach it seems, but hardly enough to hold the attention of entire nations for days at a stretch. -

All players do exercises together. All players perform following across 20 m distance (marked by cones): a. Forward skips b. Backward skips c. Inside foot touch d. Knee across body e. Back leg drive f. Arm and shoulder stretches Grip and stance: Coach demonstrates the correct grip and Base Position for seam bowling: three knee principle. Check each player for correct grip and base position. Target bowling (groups of 68/coach) (45 min) Every player has an incrediball. Check grip and base position is correct. Each group has a marked out lane of 19 yards with stumps to aim at, one player acts as wicketkeeper. Players start with walking run up to allow coach to assess action. Progress to jogging and full pace run up. Coach corrects as necessary. Line and length: Using all weather strip ask a player to chalk out a line/area for different length balls (short, good length, overpitched and yorker), inswing bowler, outswing bowler. If using the field target zones can be marked with discs or cones. Discuss reasons/tactics for varying line and length considering batsman’s hitting style and field placement. Progress to: Bowling a good length: Bowlers aim at 6‐9 cones marking out target area (rectangle) covering a good length in front of single stump. After each player has had several bowls introduce competition among individuals and then between lanes; first player/team to hit target cones 3/6 times is winner. -
Surface Characterization of Cricket Balls Using Area-Scale Fractal Analysis
Surface Characterization of Cricket Balls Using Area-scale Fractal Analysis by _________________ Omair I Paracha A Thesis submitted to the faculty of Worcester Polytechnic Institute in partial fulfillment of the requirements for the Degree of Master of Science in Mechanical Engineering January 2010 Approved: _______________________ _______________________ Professor Christopher Brown Professor Simon Evans Major Advisor Thesis Committee Member _______________________ _______________________ Professor Rajib Mallick Professor Cosme Furlong Thesis Committee Member Graduate Committee Representative Foreword Cricket is an old sport. The first recorded cricket match was played at Coxheath in Kent, England in 1646 and the first test match took place in Melbourne, Australia in 1877 between England and Australia. The Ashes series (played between Australia and England) is being organized since 1877 (Mehta, 2005). During the last century the sport has spread to over 100 countries. The governing bodies of various member countries earn millions of dollars every year from marketing and organizing cricket tournaments. Cricket Australia’s annual revenue for the year ending in June 2008 was close to a $ 134 million. The playing performance of cricket balls is one of the most important parts of a match. A faulty ball can favor one team and hence result in a loss of big sums of money for the opponents, not to mention the grief over that loss. Hence cricket ball manufacturers have to make sure that the behavior of every ball being used during the course of a tournament is similar, if not exactly the same. Wear and tear of a cricket ball is expected but they should last for a certain period of time (50 overs for a one day match and 90 overs for a test match). -
A Quantitative Approach to Influential Factors in One Day
Journal of Sports Analytics 5 (2019) 57–63 57 DOI 10.3233/JSA-170260 IOS Press A quantitative approach to influential factors in One Day International cricket: Analysis based on Bangladesh Jahidur Rahman Khana, Raaj Kishore Biswasb,∗ and Enamul Kabirb aInstitute of Statistical Research and Training, University of Dhaka, Bangladesh bSchool of Agricultural, Computational and Environmental Sciences, University of Southern View metadata,Queensland, citation and Australia similar papers at core.ac.uk brought to you by CORE provided by University of Southern Queensland ePrints Abstract. The Bangladesh Cricket Team has performed well in the recent past with steady traits of improvement. Apart from the players’ performance, some external factors are associated with the outcome of a cricket match. This paper investigates prematch toss, batting sequence, match time, opposition team’s origin and time (in years) as independent factors influencing the performance of the Bangladesh team. Outcomes of 314 One Day International (ODI) matches were fitted with a typical logistic regression model and modified Poisson model to explore the association of these factors with match results. Both models showed consistency, although the logistic model outcomes were extreme with wider confidence intervals for odds ratios, compared to the risk ratios of the modified Poisson regression model. Bangladesh, a country where cricket reflects nationalism, has shown significant improvement over time. They tend to perform better in day matches, play superior cricket against non-Asian teams and take full home advantage. Keywords: Sports, ODI Cricket, logistic model, modified poisson model, Bangladesh 1. Introduction (ODI) cricket. Accepting the performance variation among cricket players, the less discussed variables Cricket is a spectator driven sport with high eco- are considered here to check the significance of their nomic impact, attracting both local and international impacts on the outcome of a cricket match. -

The Swing of a Cricket Ball -, Vol1. No.1, JIC, Journal of Informaiton
ISSN 1750-9823 (print) International Journal of Sports Science and Engineering Vol. 07 (2013) No. 01, pp. 003-010 The Swing of a Cricket Ball – A Computational Study Chowdhury Mahbub Ashraf , SM Tareque Saifullah, Maglub Al Nur Dept. of Mechanical Engineering, Bangladesh University of Engineering & Technology, Dhaka-1000, Bangladesh (Received January 4, 2013, accepted February 9, 2013) Abstract. The mystery of cricket ball swing has fascinated the bowlers and batsmen as well as spectators and cricket critiques from the very first appearance of the game. This nonlinear flight is mainly due to the aerodynamic properties of the cricket ball which has been investigated by many researchers in the last three decades. While conducting a lot of experimental studies, their main interest was to figuring out the factors and conditions affecting the swing. However, a lot of features responsible for both conventional and reverse swing are yet to be known. In this study, rather than performing experimental study, a computational approach is undertaken to investigate the effects of different parameters on the swing of the cricket ball. The newly developed and widely used CFD (Computational Fluid Dynamics) tools and their commercial packages have been applied in this study and the effect of seam angle, bowling speed and surface roughness are considered. This study explains the conventional swing and finds out the critical combination of the above parameters to produce reverse swing with an old ball. Keywords: Conventional swing, reverse swing, side thrust, surface roughness. 1. Introduction Cricket is one of the most popular and widely watched games around the world. Though it was believed to be originated in Britain, its popularity has moved outside the British colonial countries now a day. -
A Preliminary Electromyographic Investigation Into Shoulder Muscle Activity in Cricket Seam Bowling
A PRELIMINARY ELECTROMYOGRAPHIC INVESTIGATION INTO SHOULDER MUSCLE ACTIVITY IN CRICKET SEAM BOWLING Kathleen Shorter1, Neal Smith1, Mike Lauder1 and Paul Khoury2 University of Chichester, Chichester, UK1 Sussex County Cricket Club, Hove, UK2 The aim of this investigation was to describe and compare surface electromyographic activity of shoulder musculature during cricket seam bowling between two elite bowlers with (bowler A) and without (bowler B) shoulder pathology. Activity of seven muscles were recorded at 500 Hz with a digital camera sampling at 210 Hz used to define phases within the movement. Whilst both the duration of the movement and ball velocity were similar between bowlers (bowler A: duration = 0.89 ± 0.04 s, ball velocity = 27.08 ± 1.21 m.s-1; bowler B: duration = 0.72 ± 0.02 s, ball velocity = 26.59 ± 1.49 m.s-1), variations in muscle activity particularly for biceps brachii and infraspinatus were established. Further research utilising larger sample sizes is required to establish if such variations occur as a consequence of shoulder pathology or if these are due to other contributing factors. KEYWORDS: EMG, KINETICS, INJURY, CRICKET, ROTATOR CUFF INTRODUCTION: Shoulder injury prevalence amongst seam bowlers has been reported at 0.9% with consensus amongst researchers that current injury definitions grossly underestimate the true occurrence (Bell-Jenje & Gray, 2005; Ranson & Gregory, 2008). Similar to other overhead athletes, bowlers have been found to exhibit altered joint range and strength associated with internal and external shoulder rotation which may impair the ability of the surrounding musculature to stabilise the joint and prevent migration of the humeral head during deceleration (Aginsky et al., 2004; Giles & Musa, 2008).
