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. Phase II of this research comprises three further studies that investigate several of the key components identified as important for fast bowling expertise, talent identification and development extrapolated from Phase I of this research. This multidisciplinary programme of work involves a comprehensive analysis of fast bowling performance in a cross-section of the Cricket Australia high performance pathways, from the junior, emerging and national elite fast bowling squads. Briefly, differences were found in trunk kinematics associated with the generation of ball speed across the three groups. These differences in release mechanics indicated the functional v adaptations in movement patterns as bowlers’ physical and anatomical characteristics changed during maturation. Second to the generation of ball speed, the ability to produce a range of delivery types was highlighted as a key component of expertise in the qualitative phase. The ability of athletes to produce consistent results on different surfaces and in different environments has drawn attention to the challenge of measuring consistency and flexibility in skill assessments. Examination of fast bowlers in Phase II demonstrated that national bowlers can make adjustments to the accuracy of subsequent deliveries during performance of a cricket bowling skills test, and perform a range of delivery types with increased accuracy and consistency. Finally, variability in selected delivery stride ground reaction force components in fast bowling revealed the degenerate nature of this complex multi-articular skill where the same performance outcome can be achieved with unique movement strategies. Utilising qualitative and quantitative methodologies to examine fast bowling expertise, the importance of degeneracy and adaptability in fast bowling has been highlighted alongside learning design that promotes dynamic learning environments. vi Table of Contents Keywords

  • The Swing of a Cricket Ball
    SCIENCE BEHIND REVERSE SWING C.P.VINOD CSIR-National Chemical Laboratory Pune BACKGROUND INFORMATION • Swing bowling is a skill in cricket that bowlers use to get a batsmen out. • It involves bowling a ball in such a way that it curves or ‘swings’ in the air. • The process that causes this ball to swing can be explained through aerodynamics. Dynamics is the study of the cause of the motion and changes in motion Aerodynamics is a branch of Dynamics which studies the motion of air particularly when it interacts with a moving object There are basically four factors that govern swing of the cricket ball: Seam Asymmetry in ball due to uneven tear Speed Bowling Action Seam of cricket ball Asymmetry in ball due to uneven tear Cricket ball is made from a core of cork, which is layered with tightly wound string, and covered by a leather case with a slightly raised sewn seam Dimensions- Weight: 155.9 and 163.0 g 224 and 229 mm in circumference Speed Fast bowler between 130 to 160 KPH THE BOUNDARY LAYER • When a sphere travels through air, the air will be forced to negotiate a path around the ball • The Boundary Layer is defined as the small layer of air that is in contact with the surface of a projectile as it moves through the air • Initially the air that hits the front of the ball will stick to the ball and accelerate in order to obtain the balls velocity. • In doing so it applies pressure (Force) in the opposite direction to the balls velocity by NIII Law, this is known as a Drag Force.

  • Sunday August 7, 2011
    Sunday August 7, 2011 Bhanuka's younger brother Shanuka collecting the coveted prize on his behalf from Chief guest Sidath Wettimuny riday, August 5 was a day the schoolboy cricketers of Sri Lanka will long remember. They were rewarded for their hard and untiring efforts for the F2010 season. Bata and the Sunday Times together with officials of the Sri Lanka School Cricket Association, Association of Cricket Umpires and top cricketers of yesteryear and made a grand effort to pick and choose the best schoolboy cricketers and teams. These young cricketers will undoubtedly contribute to the national stream in years to come. The grand night, the awards ceremo- ny, of the 32nd Bata-the Sunday Times Schoolboy Cricketer of the Year kicked off on Friday at the BMICH in Colombo with the distinguished patronage of former national cricketer and present interim committee member of Sri Lanka Cricket (SLC), Sidath Wettimuny as the chief guest. Among other invitees were Mr. and Mrs. Cesar Panduro (CEO of Bata), Hemaka Amarasuriya (Director, Bata), Brendon Kuruppu, Jayantha Seneviratne, Carlton Bernadus, Charith Senanayake and Hatta Tutuko (CFO, Bata). After the welcome speech from CEO of Bata, Cesar Panduro, Carlton Bernadus who is the manager of School Cricket Development at SLC made a short speech attributing the importance of recognizing the booming cricketing tal- ents in the country. But the center of all was chief guest, Sidath Wettimuny’s oration which had many thought provoking sights for young cricketers, the coaches and in particu- lar the parents. Wettimuny credited the present day cricketers who work hard to accomplish their goals going along with modern day technology.

    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. Keywords: cricket; smart cricket ball; profiling; performance; skill; spin rate; torque; bowling potential 1.

  • Cricket Memorabilia Society Postal Auction Closing at Noon 10
    CRICKET MEMORABILIA SOCIETY POSTAL AUCTION CLOSING AT NOON 10th JULY 2020 Conditions of Postal Sale The CMS reserves the right to refuse items which are damaged or unsuitable, or we have doubts about authenticity. Reserves can be placed on lots but must be agreed with the CMS. They should reflect realistic values/expectations and not be the “highest price” expected. The CMS will take 7% of the price realised, the vendor 93% which will normally be paid no later than 6 weeks after the auction. The CMS will undertake to advertise the memorabilia for auction on its website no later than 3 weeks prior to the closing date of the auction. Bids will only be accepted from CMS members. Postal bids must be in writing or e-mail by the closing date and time shown above. Generally, no item will be sold below 10% of the lower estimate without reference to the vendor.. Thus, an item with a £10-15 estimate can be sold for £9, but not £8, without approval. The incremental scale for the acceptance of bids is as follows: £2 increments up to £20, then £20/22/25/28/30 up to £50, then £5 increments to £100 and £10 increments above that. So, if there are two postal bids at £25 and £30, the item will go to the higher bidder at £28. Should there be two identical bids, the first received will win. Bids submitted between increments will be accepted, thus a £52 bid will not be rounded either up or down. Items will be sent to successful postal bidders the week after the auction and will be sent by the cheapest rate commensurate with the value and size of the item.

  • 10072 Bob Laptop Woolmer and Eddie Desktop Barlow
    10072 Bob Laptop Woolmer and Eddie Desktop Barlow Have you heard of Bob Woolmer, the former coach of South African cricket team? Unlike other conventional coaches, Woolmer relies on his laptop computer for storing and analyzing information on players, selecting team, planning match strategy etc. Since his laptop is his constant companion, people call him Bob Laptop Woolmer. Having seen Woolmer in action during World Cup ’99, the BCB (Bangladesh Cricket Board) officials sacked Gordon Abacus Greenidge (he was not willing to use computers) and decided to appoint someone as charismatic as Woolmer for coaching Bangladesh cricket team. So, Eddie Barlow was appointed as the new coach. They say that he is no less than Bob Woolmer with his computer. Then why don’t you ever see him with his laptop? That is because he doesn’t have one! Actually, he has a desktop PC, and he loves his computer so much that people call him Eddie Desktop Barlow. Now, to select Bangladesh national team for the next World Cup, Barlow has asked BCB to call a number of players to BKSP camp, so that he can minutely observe them before selection. Accordingly, BCB invites around 100 players to join BKSP camp. Barlow’s strategy for selecting the best team is as follows. He will observe each player’s batting, bowling and fielding capabilities individually, and each player will have three individual scores in these three aspects (batting, bowling and fielding). He will store each player’s scores in his hard disk. After he has scored all the players in this way, he will use his computer to select the best combination.

  • Name – Nitin Kumar Class – 12Th 'B' Roll No. – 9752*** Teacher
    ON Name – Nitin Kumar Class – 12th ‘B’ Roll No. – 9752*** Teacher – Rajender Sir http://www.facebook.com/nitinkumarnik Govt. Boys Sr. Sec. School No. 3 INTRODUCTION Cricket is a bat-and-ball game played between two teams of 11 players on a field, at the centre of which is a rectangular 22-yard long pitch. One team bats, trying to score as many runs as possible while the other team bowls and fields, trying to dismiss the batsmen and thus limit the runs scored by the batting team. A run is scored by the striking batsman hitting the ball with his bat, running to the opposite end of the pitch and touching the crease there without being dismissed. The teams switch between batting and fielding at the end of an innings. In professional cricket the length of a game ranges from 20 overs of six bowling deliveries per side to Test cricket played over five days. The Laws of Cricket are maintained by the International Cricket Council (ICC) and the Marylebone Cricket Club (MCC) with additional Standard Playing Conditions for Test matches and One Day Internationals. Cricket was first played in southern England in the 16th century. By the end of the 18th century, it had developed into the national sport of England. The expansion of the British Empire led to cricket being played overseas and by the mid-19th century the first international matches were being held. The ICC, the game's governing body, has 10 full members. The game is most popular in Australasia, England, the Indian subcontinent, the West Indies and Southern Africa.
