The primary aim of this study was to evaluate the effectiveness of an injury prevention and training programme for elite cricketers in regard to biomechanical, physical and motor and anthropometric variables over a period of six cricketing off-seasons (1998/1999-2003/2004). A secondary aim was to investigate the injury epidemiology of elite cricket players over a six-season period (1998/1999 – 2003/2004). A total of 93 cricket players, who were part of the North-West professional cricket squad, were evaluated over a six-season period stretching from the 1998/1999 cricket season to 2003/2004 cricket season. The players were all evaluated at the end of the off-season (middle September) of the commencing season and the injury lists were compiled throughout each playing season. This included all players who needed medical attention due to injury sustained while representing the North-West cricket team in a cricket match. An analysis was done of literature sources by making use of electronic media, library search and sports medicine journals. Databases such as Pubmed, EbscoHost (Academic Search Elite), Sciencedirect, Medline, Eric, Health Source - Consumer Edition, Health Source: Nursing/Academic Edition and SPORTDiscus were used. Special consideration was given to cricket injury epidemiology, injury prevention strategies in cricket, biomechanics in cricket and general injury prevention strategies. The recorded data were statistically processed and the practical significances were calculated. Three different protocols were followed to evaluate the effectiveness of the injury prevention and training programme. The recorded data were analysed for the six off-season periods (1998/1999-2003/2004, protocol 1) of the study for the biomechanical, physical and motor and anthropometric evaluations, as well as for the injury epidemiology. The players were then divided into four exposure times (protocol 2) in the study for the biomechanical, physical and motor and anthropometric evaluations. Then the players were divided into two groups (protocol 3), with each group consisting of the same players, and over a three off-season period each evaluated for the biomechanical, physical and motor and anthropometric variables. Lastly, the results for the last three seasons of protocol 1 were compared with the result of the last three seasons of protocol 3 (group 2) for the biomechanical, physical and motor and anthropometric evaluations, as well as for the injury epidemiology. The results for this study indicate that the injury prevention and training programme was successful in improving and maintaining the biomechanical, physical and motor and anthropometric profile of the cricketers over the six off-season periods (1998/1999-2003/2004). Although all injuries could not be prevented, injuries resulting from structural vulnerability did decrease. Injuries resulting from structural vulnerability (mechanism of injury) decreased from the 1998/1999 season (67,67% of the total injuries suffered during the 1998/1999 season) to the 2003/2004 season (10% of the total injuries suffered during the 2003/2004 season), indicating that the training and prevention programme played a role in the prevention of these injuries. Injury incidence per 10 000 hours of play was 5,82 injuries for the six-season period (1998/1999- 2003/2004). The injury prevention and training programme used in this study can be utilised to improve the biomechanical, physical and motor and anthropometric profile of cricketers. The biomechanical, physical and motor and anthropometric evaluations can also be used as injury prevention strategies by identifying possible injury risk factors as a result of poor biomechanical, physical and motor and anthropometric profiles. / Thesis (Ph.D. (Education))--North-West University, Potchefstroom Campus, 2005.

Studiens syfte är att undersöka förekomsten av spelrelaterade muskuloskeletala besvär hos gitarrlärare och elever samt typen av skador. Studien syftar också till att undersöka gitarrlärares attityder till, och tillämpning av, skadeförebyggande strategier. För det tredje syftar studien till att undersöka signifikanta samband mellan skadeförebyggande metoder och förekomsten av spelrelaterade besvär. Tidigare forskning rör vanliga spelrelaterade besvär, riskfaktorer och skadeförebyggande strategier. En surveyundersökning med enkät användes för att besvara studiens forskningsfrågor. 166 gitarrlärare besvarade enkäten. Resultaten visar att 72,3% av gitarrlärarna har själva och upplevt spelrelaterade besvär och 31,9% av gitarrlärarna har haft ele- ver med spelrelaterade besvär. Den vanligaste typen av besvär var med muskler och senor. Gitarrlärarna tenderar att skadeförebyggande strategier i mindre utsträckning i undervisning jämfört med i deras egna spelande. Några statistiskt signifikanta samband hittades mellan gitarrlärares attityder till, och tillämpning av, skadeförebyggande strategier och förekomsten av spelrelaterade besvär. Generellt sett använde gitarrlärare vissa skadeförebyggande strategier i sitt spelande och undervisning i högre utsträckning om de hade erfarenhet av spelrelaterade besvär. I diskussionsdelen lyfts aspekter av resultatet i relation till tidigare presenterad forskning. / The aim of this study was to research the prevalence of playing related musculoskeletal problems in guitar teachers and their students as well as the types of injuries. The study also aims to investigate guitar teachers attitudes towards, and application of, different injury prevention strategies. Third, the study aims to investigate any significant interconnections between injury prevention methods and the prevalence of playing related problems. Previous research deals with common playing related problems, risk factors and injury prevention strategies. A survey study with a questionnaire was used to answer the research questions. 166 guitar teachers answered the questionnaire. The results show that 72,3% of the guitar teachers have experienced playing related problems themselves and that 31,9% of the guitar teachers had had students with playing related problems. The most common problem was with muscles and tendons. Guitar teachers tended to use injury prevention methods less in teaching compared to their own playing. Some statistically significant interconnections were found between guitar teachers’ attitudes towards, and application of, injury prevention strategies and the prevalence of playing related problems. In general, guitar teachers with experience of playing related problems were more likely to use some of the injury prevention strategies in their playing and teaching. The discussion section lifts aspects of the results in relation too previously presented research.
