These working cyclists are often Latino or Asian male immigrants who are situated within intersectional and interlocking systems of global migration and capital flows, intense time pressures by restaurants and customers, precarious tip-based livelihoods, an e-bike ban and broken windows policing, and unsafe streets designed for drivers. -
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.

Measuring Spin Characteristics of a Cricket Ball
12:00-12:15 pm Aaron J. Beach. Measuring spin characteristics of a cricket ball. (230) MEASURING SPIN CHARACTERISTICS OF A CRICKET BALL Aaron Beach, René Ferdinands and Peter Sinclair Exercise and Sport Science, Faculty of Health Sciences, University of Sydney, Sydney Australia The purpose of this paper is to outline an experimental procedure for measuring the spin rate and direction of spin axis of a cricket ball in flight. While the spin rate and horizontal direction of the spin axis are important for deviation upon impact with the ground, the lateral movement of the ball in the air requires a vertical elevation angle of the ball’s spin axis. Using three markers on the ball, a 3D Cortex motion analysis system was used to measure the vertical and horizontal components of the spin axis from six deliveries of ten bowlers of varying playing levels. Software was programmed to graphically display the magnitude and direction of the ball spin during the live capture, making it a potentially valuable performance analysis tool. The results show that bowlers had substantial differences in spin rate and spin axis orientation depending on their playing level. KEY WORDS: cricket, spin bowling, spin, flight, swerve. INTRODUCTION: In contrast to the athleticism of fast bowling in cricket, spin bowling is a more tactical and deceptive art. While spin bowlers generally aim to deceive batsmen by causing the ball to alter the direction of its bounce off the ground, another effective tactic is to make the ball deviate from its natural projectile motion during its flight. Two factors are commonly associated with the ball’s flight, often referred to as dip and drift. -
Issue 40: Summer 2009/10
Journal of the Melbourne Cricket Club Library Issue 40, Summer 2009 This Issue From our Summer 2009/10 edition Ken Williams looks at the fi rst Pakistan tour of Australia, 45 years ago. We also pay tribute to Richie Benaud's role in cricket, as he undertakes his last Test series of ball-by-ball commentary and wish him luck in his future endeavours in the cricket media. Ross Perry presents an analysis of Australia's fi rst 16-Test winning streak from October 1999 to March 2001. A future issue of The Yorker will cover their second run of 16 Test victories. We note that part two of Trevor Ruddell's article detailing the development of the rules of Australian football has been delayed until our next issue, which is due around Easter 2010. THE EDITORS Treasures from the Collections The day Don Bradman met his match in Frank Thorn On Saturday, February 25, 1939 a large crowd gathered in the Melbourne District competition throughout the at the Adelaide Oval for the second day’s play in the fi nal 1930s, during which time he captured 266 wickets at 20.20. Sheffi eld Shield match of the season, between South Despite his impressive club record, he played only seven Australia and Victoria. The fans came more in anticipation games for Victoria, in which he captured 24 wickets at an of witnessing the setting of a world record than in support average of 26.83. Remarkably, the two matches in which of the home side, which began the game one point ahead he dismissed Bradman were his only Shield appearances, of its opponent on the Shield table. -

Surface EMG-Based Profiling and Fatigue Analysis of the Biceps Brachii Muscle of Cricket Bowlers
Surface EMG-based Profiling and Fatigue Analysis of the Biceps Brachii Muscle of Cricket Bowlers Muhammad Usama Rizwan, Nadeem Ahmad Khan, Rushda Basir Ahmad and Muneeb Ijaz Department of Electrical Engineering, Lahore University of Management Sciences, Lahore, Pakistan Keywords: EMG, Mean Power Frequency, Fatigue Analysis, Cricket Bowling, Player Profile, Player Development. Abstract: Cricket bowling action is a complex repetitive task involving multiple muscles. In this paper we present a protocol to analyse accumulated localized fatigue in muscles during cricket bowling action. Biceps Brachii (BB) muscle in case of fast delivery for a novice player is analysed to illustrate the methodology. Synchronized video recording with the surface EMG signal was captured from the medial position of the BB muscle to enable segmentation of the EMG signal in six intervals corresponding to the six phases of the bowling action. This enables study of the activation pattern of the muscle along with the fatigue trend during bowling. Both integrated EMG and Mean Power frequency (MPF) are used as measures to analyse fatigue. Though we have plotted the trends for a single muscle, a similar exercise should be repeated for all important muscles involved. Analysing localized fatigue in individual muscles is important for injury prevention as well as player performance development. It can help to see how individual muscle fatigue contributes in declining performance during cricket bowling. Such an analysis can also be used to support minimum bowling overs and suitable inter-over breaks for a specific bowler with regard to injury prevention and optimal performance. 1 INTRODUCTION is a commercially available device for acquiring bio- potential data. -
ECB Fast Bowling Match Directives
ECB Fast Bowling Match Directives Age Max. overs per spell Max. overs per day Up to U13 5 10 U14, U15 6 12 U16, U17, U18, U19 7 18 For the purpose of these Directives a fast bowler is defined as a bowler to whom a wicket keeper in the same age group would in normal circumstances stand back to take the ball. Having completed a spell the bowler cannot bowl again, from either end, until the equivalent number of overs to the length of his* spell have been bowled from the same end. A bowler can change ends without ending his current spell provided that he bowls the next over that he legally can from the other end. If this does not happen his spell is deemed to be concluded. If play is interrupted, for any reason, for less than 40 minutes any spell in progress at the time of the interruption can be continued after the interruption up to the maximum number of overs per spell for the appropriate age group. If the spell is not continued after the interruption the bowler cannot bowl again, from either end, until the equivalent number of overs to the length of his spell before the interruption have been bowled from the same end. If the interruption is of 40 minutes or more, whether scheduled or not, the bowler can commence a new spell immediately. In matches of 20 overs or less per team where the competition regulations only allow bowlers to bowl less than or equal to the number of overs specified as the maximum in a spell in the Directives the provisions requiring an equivalent number of overs from the same end to have elapsed before a subsequent spell can commence shall not apply (e.g. -
A Multidisciplinary Examination of Fast Bowling Talent Development in Cricket
A MULTIDISCIPLINARY EXAMINATION OF FAST BOWLING TALENT DEVELOPMENT IN CRICKET Elissa Jane Phillips BPhEd & MSc (Hons) Submitted in fulfilment of the requirements for the degree of Doctor of Philosophy School of Human Movement Studies Faculty of Health Queensland University of Technology 2011 ii Keywords Biomechanics, cricket, dynamical systems theory, degeneracy, expertise, fast bowling, skill acquisition, metastability, multidisciplinary, talent development, variability. iii iv Abstract Research on expertise, talent identification and development has tended to be mono-disciplinary, typically adopting geno-centric or environmentalist positions, with an overriding focus on operational issues. In this thesis, the validity of dualist positions on sport expertise is evaluated. It is argued that, to advance understanding of expertise and talent development, a shift towards a multidisciplinary and integrative science focus is necessary, along with the development of a comprehensive multidisciplinary theoretical rationale. Dynamical systems theory is utilised as a multidisciplinary theoretical rationale for the succession of studies, capturing how multiple interacting constraints can shape the development of expert performers. Phase I of the research examines experiential knowledge of coaches and players on the development of fast bowling talent utilising qualitative research methodology. It provides insights into the developmental histories of expert fast bowlers, as well as coaching philosophies on the constraints of fast bowling expertise. Results suggest talent development programmes should eschew the notion of common optimal performance models and emphasize the individual nature of pathways to expertise. Coaching and talent development programmes should identify the range of interacting constraints that impinge on the performance potential of individual athletes, rather than evaluating current performance on physical tests referenced to group norms. -

The Kinematics of Batting Against Fast Bowling in Cricket
THE KINEMATICS OF BATTING AGAINST FAST BOWLING IN CRICKET by CHRIS PEPLOE A Doctoral Thesis Submitted in partial fulfilment of the requirements for the award of Doctor of Philosophy of Loughborough University July 2016 © by Chris Peploe, 2016. ABSTRACT In cricket, batting against a fast bowler is thought to be one of the most challenging tasks a player must undertake. Despite this, minimal research exists investigating the techniques used by batsmen, with the majority of research focussed on injury mechanisms and pace generation in fast bowlers. The aim of this study was to investigate the techniques used by elite and amateur batsmen in a training environment, such that key aspects of batting technique relating to success could be extracted, and recommendations for future coaching practice and player development could be made. A novel methodology was developed for the collection of full body three-dimensional kinematic data of cricket batsmen in a realistic training environment. Kinematic and high-speed video (250 Hz) data were collected for 31 batsmen, and a three-dimensional full body biomechanical model was developed. Batsmen performed forward drive and pull shots against different delivery methods. Key events and kinematic parameters were defined, and used to produce detailed biomechanical descriptions of the forward drive and pull shots. A curve fitting methodology was developed and validated to determine the impact location of the ball on the bat face, and used to investigate the effects of impact location on shot outcome during a range hitting task. Impacts further from the sweetspot were found to generate lower ball speeds and decrease shot accuracy through bat twist.
