Introduction: With batting in cricket, there is no known end point, making the allocation of resources and the development of a suitable pacing strategy more difficult. How batsmen allocate resources and pace themselves when repeatedly sprinting between the wickets is therefore not known. According to the ‘anticipatory feedback’ model, the level of expertise/experience has a substantial influence on the development of a suitable pacing strategy. Skilled or experienced batsmen may therefore have a greater ability to develop and implement a pacing strategy compared to that of novice or less-skilled batsmen. Purpose: To assess whether the absence of a known end point at the beginning of repeated sprint bouts between the wickets effects how batsmen pace themselves comparing skilled and less-skilled batsmen. Methods: Twenty-four male cricketers from a university league were selected. Twelve skilled batsmen (players in the top five batting order), and 12 less-skilled batsmen (players in the bottom five batting order) completed three experimental. All trials required batsmen to complete the same number of shuttle sprints (14 shuttles and therefore 28 runs), while only the information provided before each trial differed. Control Trial: This trial is also referred to as the ‘informed’ trial as the batsmen are aware of the exercise requirements (end point). Unknown Trial: The batsmen were not informed of the exercise end point and were required to run on command for an indefinite period (28 runs). Deceptive Trial: Batsmen’ were incorrectly informed with regards to the number of sprints (told they were only doing 14 runs when in fact they were doing 28 runs). Muscle activity, sprint times and RPE measures were obtained during all three trials and compared. Results: Significant (p<0.05) group effects were apparent for sprint times and, ‘central’ and ‘local’ RPE. Specifically, skilled batsmen obtained the faster mean sprint times, and less-skilled batsmen reported the higher mean ‘central’ and ‘local’ RPE values in all three experimental trials. There were no significant group effects for muscle activation. Skilled batsmen did however have lower muscle activation compared to less-skilled batsmen in all three trials. Furthermore, general trends revealed that sprint times and muscle activation decreased over time (from shuttle 1 to shuttle 14), and RPE (‘central’ and ‘local’) ratings increased, regardless of the experimental trials. Skilled batsmen performed the best in all three trials. This was determined by the attainment of faster sprint times, lower muscle activation and low RPE ratings in each of the three trials. The assessment of the relationship of the dependent variables measured in each trial, did however suggest that skilled batsmen performed best in the deceptive trial while less-skilled batsmen performed best in the control trial. Skilled batsmen thus showed superior performance when trial requirements were unclear. Less-skilled batsmen however, were seen to experience decrements in performance when information regarding the end point was unknown or misleading. Conclusion: It can thus be concluded that previous experience facilitates in the obtainment of improved sprint times between the wickets, especially when the exact end point is unknown.

After years of isolation from the international sporting arena, South African sports teams have recently achieved much success. This study is concerned specifically with managing for organisational effectiveness in South African cricket. According to the theory of transformational leadership, there should be a positive relationship between this style of leadership and organisational effectiveness. The Multifactor Leadership Questionnaire was used to collect information about leadership while data for organisational effectiveness, the dependent variable, was collected using the Effectiveness Survey for Cricket Administration. Most of the results regarding the relationship of the transformational leadership factors and organisational effectiveness were significant. On the other hand, most of the results regarding the relationship of the transactional leadership factors and organisational effectiveness were not significant. The overall results provide general support of the relevance of the transformational leadership theory in the context of cricket administration in South Africa. The results also support Bass's (1990b) argument of the universal application of the transformational leadership theory.

Since its inception, consumption behaviour theory has developed to account for the important social aspect that underpins or at least to some extent can be used to explain consumption behaviour. Modern consumption behaviour theory is anthropocentric in nature, with people and societal influence at the forefront of the theory. To date, empirical studies on consumption behaviour of cultural activities (for example, music and arts), entertainment and sport have used Bourdieu’s (1984) omnivore/univore theory to suggest that consumption of leisure activities is bound up in social ties. To date, no such investigation has been conducted in the context of sport in South Africa. The aim of the study therefore is to investigate whether South African cricket spectators are sporting omnivores or univores, thus, essentially investigating whether sports consumption behaviour in South Africa is bound up in social ties. A number of positive economic and social ramifications could result from gaining a holistic understanding of sports consumption behaviour in South Africa. Given these ramifications, the secondary goal of the research is to identify motives for consumers making specific sport consumption decisions, and determining whether certain characteristics can be attributed to these consumption decisions. Recommendations based on the findings of the research could help various stakeholders understand sports consumption patterns in South Africa, which could in turn lead to the realization of positive economic and social benefits. The study made use of a questionnaire, administered at four different limited overs cricket matches in the 2012/13 cricket season, to obtain a range of responses reflecting specific types of consumption behaviour as well as motives for consumption decisions of cricket spectators in the Eastern Cape. Using individual binary probit models and post estimation F-tests, the results indicate that consumption behaviour of sport within South Africa predominantly differs on the grounds of education and race. This suggests that there are aspects of social connotations underpinning sports consumption behaviour within South Africa

Magister Artium (Sport, Recreation and Exercise Science) - MA(SRES) / Over the years cricket has developed from a traditional and conservative game into an extremely lucrative sport, which requires a great deal of professionalism in all surrounding areas. In recent years cricket has evolved and resulted in the emergence of Twenty20 cricket. The aim of this study focused on identifying batting trends through a comparative analysis between Varisty Cup winning teams and the University of the Western Cape Cricket Club between the age group of 18 – 25. The study used a quantitative research approach with a content analysis methodology research design. Nine key batting variables were analysed in three phases of a cricket match (Powerplay, Middle overs and Death overs) between winning teams and the University of the Western Cape Cricket Club to establish the magnitude of differences (Cohen’s effect size). The top indicators for success in the tournament were averaging a higher number of boundary fours, accumulating a higher number of single runs throughout the match, averaging a high number of sixes during the Middle and Death Overs of a batting innings and accumulating two’s throughout all three phases of a match. The overall summary of this study’s results navigates to a batting strategy that should focus on batting trends by maintaining a higher batting run rate, target to scoring more boundary fours and sixes, good running between the wickets to accumulate two’s, select batsmen with a low dismissal rate and select batsmen with a high single scoring rate [equates to better strike rotation].

This essay discusses the translation of terms in four texts on cricket. The first aim of the essay was to identify the most appropriate translation strategy for each term based on Niska and Frøili’s (1992:361) six translation strategies. Their strategies were complemented by considerations of equivalence and Swedish grammar and language structure. The identified terms were divided into the categories Players, Field &amp; Equipment and Rules &amp; Scoring and the second and third aims of the essay were to investigate if a particular translation strategy was more commonly used for all the cricket terms, as well as if a particular translation strategy was more frequently used for a specific category. This information can aid translators in the decision making when translating new cricket terms. The result showed that direct transfer and translation of an explanation of the source term were more frequently used, sometimes in a combination in the form of a translation doublet. With regards to the three categories, direct transfer was used in the majority of term translations in the category Rules &amp; Scoring, while the strategies were more evenly distributed for the other two categories. No reliable conclusions can be drawn from the results in this essay as a much larger sample would be required. It may, however, be an indication of that certain translation strategies are more applicable in the translation of cricket terms and can be used as a starting point for future studies.

Thesis (MScPhysio)--University of Stellenbosch, 2011. / ENGLISH ABSTRACT: Aim: The aim of the study was to improve understanding of the hip joint kinematics in cricket fast bowlers and to ascertain whether a relationship exists between hip joint biomechanical parameters, including kinematics, ROM characteristics and lumbar symptoms. Study design: A descriptive cross-sectional study was conducted. Participants: Sixteen adult male fast bowlers between the ages of 18 and 40 years old, playing first-club league, were featured in the study. Main outcome measures: To obtain data with regards to the training history, as well as the nature of lumbar-spine symptoms experienced by the cricket fast bowlers, a newly designed questionnaire was compiled. For analysis of the front foot hip joint ROM and kinematics, the biomechanical equipment used included: a two-dimensional Canon MV950 Digital Video Camcorder, a Kodak EasyShare C310 camera and XSENS Motion Tracking equipment (Xsens Technologies B. V., Enschede, Netherlands). Results: Eight of the sixteen bowlers in our study experienced LBP in the season with seven of these bowlers presenting with recent symptoms most of which are experienced after bowling a spell and described as “tightness” or a “stabbing pain” in the lower back. Intensity of LBP ranged between 1/10 to 8/10. Front foot hip joint kinematics of fast bowlers showed highly individualised patterns of movement between different subjects. Medium amplitude movements in the flexion/extension as well as the rotation plane of movement showed a significant difference in bowlers with- and without LBP. No significant differences between groups with LBP and without LBP were found in the three passive hip ROM measurements. Conclusions: It has proved to be very difficult to improve the understanding of the front foot hip biomechanics in cricket fast bowlers due to the high inter-subject variability. Variability in movement patterns remains under-researched by sports biomechanics. Although decreased hip mobility could alter mechanical forces transmitted to the lumbar spine and therefore predispose or be a causative factor in LBP development, this study found no significant relation between these parameters. The sample size was very small in this study which will influence the validity of results. Our study confirmed the high incidence of LBP and preventative efforts for bowlers should therefore be strongly supported. / AFRIKAANSE OPSOMMING: Doelwit: Die doelwit van die studie was om die heupgewrig kinematika van krieket snelboulers beter te verstaan en om vas te stel of daar ‘n verwantskap bestaan tussen heupgewrig biomeganiese parameters, insluitende kinematika, omvang van beweging karakter en lumbale simptome. Studie ontwerp: ‘n Deursneë beskrywende studie is onderneem. Deelnemers: Sestien volwasse manlike snelboulers tussen die ouderdomme van 18 en 40 jaar oud wat eerste liga speel maak deel uit van die studie. Hoof uitkoms maatreëls: ‘n Nuut ontwerpte vraelys is opgestel om data aangaande oefen geskiedenis sowel as aard van lumbale simptome wat deur krieket snelboulers ervaar word in te samel. Die biomeganiese apparaat wat gebruik is vir die analiese van die voorvoet heup omvang van beweging, sowel as die kinematika, sluit in: ‘n twee dimensionele Canon MV950 Digitale Video Camcorder, ‘n Kodak EasyShare C310 kamera en XSENS beweging volgende apparaat (Xsens Technologies B. V., Enschede, Netherlands). Resultate: Agt van die sestien boulers in ons studie het lae rug pyn in die seisoen ervaar. Sewe van die boulers het gepresenteer met onlangse simptome waarvan die meeste na ‘n bouler se boulbeurt ervaar is en beskryf was as ‘n “styfheid” of “steekpyn” in die lae rug. Die intensiteit van die lae rug pyn het gewissel tussen 1/10 en 8/10. Voorvoet heup kinematika van snelboulers het hoogs individualistiese patrone van beweging getoon tussen verskillende deelnemers. Medium amplitude bewegings in die fleksie/ekstensie sowel as die rotasie plein van beweging het ‘n beduidende verskil tussen boulers met- en sonder lae rug pyn getoon. Geen beduidende verskille tussen die groep met- en sonder rugpyn is gevind met die drie passiewe heup omvang van beweging meetings nie. Gevolgtrekkings: Dit blyk baie moelik te wees om die voorvoet heup biomeganika in krieket snelboulers beter te verstaan a.g.v. die hoë inter-deelnemer veranderlikheid. Veranderlikheid in bewegings patrone is nog nie genoeg nagevors deur sport biomeganici nie. Alhoewel ingekorte heup mobiliteit meganiese kragte wat deur die lumbale werwelkolom gaan kan wysig, en sodoende die ontwikkeling van lae rug pyn kan predisponeer of ‘n oorsakende faktor kan wees, het hierdie studie nie ‘n beduidende verwantskap tussen die parameters gevind nie. Die steekproef groote was baie klein en dit sal die geldigheid van die resultate beïnvloed. Ons studie het die hoë insidensie van lae rug pyn bevestig en pogings tot voorkomende maatreëls moet daarom ten sterkste ondersteun word.

Thesis (M.Tech.: Chiropractic)- Dept. of Chiropractic, Durban University of Technology, 2008. x, 52 leaves, Appendices A-E, [25] leaves. / To determine whether a relationship exists between core stability and bowling speed in Action Cricket bowlers. Methods: Thirty asymptomatic indoor Action Cricket fast and fast-medium bowlers were divided into two groups of 15 each, with Group A having well-developed core stability and group B having poorly-developed core stability. The concept of matched pairs was used for age and cricket experience in order to maintain homogeneity between the groups. The core stability and bowling speed of each participant was measured using a pressure biofeedback unit (PBU) and speed sports radar respectively. SPSS version 15.0 was used to analyse the data.

Cricket has evolved from a traditional and conservative sport to a fast-paced, vigorous game. As a result of this the physical conditioning programmes of players have changed drastically with regular fitness tests that are now an integral part of these programmes. In spite of this, no studies have made an attempt to determine the exact relationship between the physical and motor ability parameters of batsmen and their performance. The purpose of this study was, therefore, firstly to determine which physical and motor ability parameters discriminate between successful and less successful provincial academy batsmen and secondly, to determine how much these parameters contribute to the batting performance of provincial academy batsmen. Twenty-two batsmen from the Gauteng and North-West cricket academies in South Africa were used in this study. Thirteen batsmen (20.15 +- 1.41 years) participated during the 2004 season whilst nine batsmen (21.11 +- 1.83 years) took part during the 2005 season. The players were subjected to 23 physical and motor ability tests, whilst 72 isokinetic measurements were also taken. The data was analysed by means of descriptive statistics, cluster analyses, forward stepwise discriminant analyses and finally forward stepwise multiple regression analyses. The discriminant analyses showed that right (RKEPT) and left knee extensor peak torque (LKEPT), right knee extensor average power (RKEAP), left knee extensor total work (LKETW) and left knee flexor peak torque (LKFPT) (all at 30°/sec), as well as LKEPT, RKEPT and L.KEAP (all at 24O°/sec ), left (LIRAP) and right shoulder internal rotator average power (RIRAP). right shoulder external/internal rotator peak torque ratio (REIRPTR) and right shoulder internal rotator peak torque (RIRPTJ (all at 24O°/sec) as well as left shoulder internal rotator total work (LIRTW) (60°/sec) discriminated non-significantly between the successfu1 (top 5 ranked batsmen of both seasons) and less successful academy batsmen. The physical and motor ability parameters which were identified as discriminators were left 505 agility, shuttle run aerobic endurance and IRM (repetition-maximum) hack squat strength (all significant) (p 5<= 0.05) whilst left grip strength and abdominal muscle strength discriminated non-significantly. The forward stepwise multiple regression analyses indicated that RKEPT 30' (16%). LKEPT 30' (7%), RKEAP 30' (7%), LKFPT 30' (7%), LKEAP 240" (6%), RKFPT 240" (5%). LKETW 30" (5%) and LKEPT240° (4%) were the isokinetic knee strength parameters which contributed non-significantly to batting performance. The isokinetic shoulder strength parameters which also contributed non-significantly to batting performance were: RIRPT240° (28%). LIRAP 240' (16%), REZRPTR 240' (8%). LIRTW 60° (5%) and RIRAP 240' (4%). Vertical jumping power (13%) (p 50.05), left 505 agility (9%) (p 50.05), abdominal muscle strength (5%) (p 50.05), aerobic capacity (10%). IRM bench press strength (7%), IRM hack squat strength as well as left shoulder internal rotation flexibility (4% each) were the physical and motor ability parameters which contributed to batting performance. The conclusion that can, therefore, be drawn is that physical and motor ability parameters contribute to the performance of provincial academy batsmen and that these components should be included in the physical conditioning programmes of batsmen / Thesis (M.Sc.

Visually guided navigation represents a long standing goal in robotics. Insights may be drawn from various insect species for which visual information has been shown sufficient for navigation in complex environments, however the generality of visual homing abilities across insect species remains unclear. Furthermore variousmodels have been proposed as strategies employed by navigating insects yet comparative studies across models and species are lacking. This work addresses these questions in two insect species not previously studied: the field cricket Gryllus bimaculatus for which almost no navigational data is available; and the European desert ant Cataglyphis velox, a relation of the African desert ant Cataglyphis bicolor which has become a model species for insect navigation studies. The ability of crickets to return to a hidden target using surrounding visual cues was tested using an analogue of the Morris water-maze, a standard paradigm for spatial memory testing in rodents. Crickets learned to re-locate the hidden target using the provided visual cues, with the best performance recorded when a natural image was provided as stimulus rather than clearly identifiable landmarks. The role of vision in navigation was also observed for desert ants within their natural habitat. Foraging ants formed individual, idiosyncratic, visually guided routes through their cluttered surroundings as has been reported in other ant species inhabiting similar environments. In the absence of other cues ants recalled their route even when displaced along their path indicating that ants recall previously visited places rather than a sequence of manoeuvres. Image databases were collected within the environments experienced by the insects using custompanoramic cameras that approximated the insect eye viewof the world. Six biologically plausible visual homing models were implemented and their performance assessed across experimental conditions. The models were first assessed on their ability to replicate the relative performance across the various visual surrounds in which crickets were tested. That is, best performance was sought with the natural scene, followed by blank walls and then the distinct landmarks. Only two models were able to reproduce the pattern of results observed in crickets: pixel-wise image difference with RunDown and the centre of mass average landmark vector. The efficacy of models was then assessed across locations in the ant habitat. A 3D world was generated from the captured images providing noise free and high spatial resolution images asmodel input. Best performancewas found for optic flow and image difference based models. However in many locations the centre of mass average landmark vector failed to provide reliable guidance. This work shows that two previously unstudied insect species can navigate using surrounding visual cues alone. Moreover six biologically plausible models of visual navigation were assessed in the same environments as the insects and only an image difference based model succeeded in all experimental conditions.
