Sports scientists and trainers generally agree that the multidimensional training in tennis should start during early childhood in order to ultimately reach a professional playing standard. Evidence suggests that motor skills, including power, strength, agility, speed and explosive power, as well as mental strength and a highly developed neuromuscular coordinating ability are strongly correlated with the level of tournament performance. Turner&Dent (1996) found that 27% of all tennis injuries in junior players occur in the shoulder region. The shoulder girdle is prone to injury because of its ability to maximally accelerate and decelerate the arm while the arm maintains it maintains precise control over the racquet at ball contact. The purpose of this study was to determine whether the occurrence of shoulder injuries could be minimized in tennis players by following a specific exercise programme, focusing on the shoulder girdle. A total of 42 tennis players participated in this study. They were all aged between 14 and 18 years. Both males and females were used for the purpose of this study. All the players were training at the SA Tennis Performance Centre and the International Tennis Federation at the University of Pretoria. They were all elite tennis players practising daily and scheduled for standard major tournaments throughout the year. Each subject completed a questionnaire of his or her tennis and medical history. The players were then divided into a control group and an experimental group. Both groups completed a series of physical scientific tests, consisting of posture analysis, body composition, flexibility, functional strength of the upper body; and isokinetic power and endurance of the shoulder muscles. These tests were executed every 3 months over a 9-month period and the results of each battery of tests were used to adjust and upgrade the new programmes. The experimental group did specific preventative shoulder exercises 5 times a week in addition to their usual gymnasium programme twice a week, while the control group followed a normal strengthening programme twice a week. A medical doctor immediately evaluated any muscle stresses or pains throughout the year. At the end of the year the data was compared to determine the difference in injury occurrence between the two groups. There was a significant difference (p<0.05) in the distribution of the lean body mass with the Lean body mass at T1 being lower than the Lean body mass at T3 in the control group. In the experimental group the fat percentage showed a significant decrease (p<0.05) from T1 to T3. The distribution of the muscle percentage at T1 was significantly different (p<0.05) from the distribution of the muscle percentage at T3 in the experimental group with the muscle percentage at T1 being lower than the muscle percentage at T3. There was a significant difference between the control and experimental group for 1RM bench press (p<0.05) with the 1RM bench press measurements at T3 being lower for the control group than for the experimental group. Also, the 1RM bench press at T1 was lower than the 1RM bench press at T3 in the experimental group. The experimental group showed a significant increase from T1 to T3, peaking at T3 with the 1RM bench press. Results of the tests done to determine isokinetic muscle strength showed that a statistical significant correlation (p<0.05) was found with regard to the strength of the internal rotators of the non-dominant shoulder at T3, with the experimental group having a higher measurement than the control group. The internal rotators and external rotators of both the dominant and non-dominant shoulders were lower at T1 than at T3 in the experimental group (p<0.05). The external rotators of the non-dominant shoulder at T1 were lower than the external rotators of the non-dominant shoulder at T3 in the control group. Results of the tests done to determine flexibility showed a statistically significant difference with the internal rotators and external rotators of the dominant as well as the non-dominant shoulders being lower at T1 than at T3 in the experimental group. Also, the external rotators of the non-dominant shoulder of the control group were lower at T1 than at T3. Results of the tests done to determine posture showed that in the control group, 54.5% of the players had scoliosis at T1 as opposed to 40.9% at T3. In the experimental group 55% had scoliosis at T1 compared to the 30% at T3. In the experimental group, 55% of the players’ shoulder heights were not level at T1, compared to 30% at T3. 63.6% of the control group’s non-dominant shoulders were higher than the dominant shoulder at T1, compared to the 40.9% of subjects at T3. Among the subjects in the experimental group, 50% had a higher non-dominant shoulder and 5% a higher dominant shoulder at T1, compared to 25% and 5% respectively in the control group, at T3. Results of the tests done to determine the occurrence of injuries, showed that the subjects with no injuries in the control group stayed stable from T1 (54.5%) to T2 (54.5%) whereafter it increased to 59.1% at T3. The experimental group stayed stable from T1 (55.0%) to T2 (55.0%) where after it increased to 85% at T3. In the control group the percentage grade 1 and 2 injuries was 13.6% at T1, increasing to 18.2% at T2, and decreasing to 13.6% at T3. In the experimental group 15% of the subjects had grade 1 injuries at T1. This percentage increased to 30% at T2 where after it decreased to 15% at T3 again. The percentage of subjects with grade 2 injuries in the experimental group remained stable at 10.0% from T1 to T2. None of the subjects had grade 2 injuries at T3. In the control group 9% had grade 3 injuries at T1, with none at T2 and T3. In the experimental group the percentage of subjects with grade 3 injuries remained stable at 5.0% from T1 to T2. None of the subjects had grade 3 injuries at T3. In the control group 4.5% of subjects had grade 4 injuries at T1. This stayed more or less stable at T2 (4.6%) and increased to 9.1% at T3. In the experimental group 10.0% had grade 4 injuries at T1. None of the subjects had grade 4 injuries at either T2 or T3. In the control group 4.5% had grade 5 injuries at T1, none had it at T2, and 4.5% had it at T3. In the experimental group none of the subjects had grade 5 injuries at T1, T2 or T3. In the control group none of the subjects had grade 6 injuries at T1 or T3. At T2, however, 4.6% had grade 6 injuries. In the experimental group 5.0% of the subjects had grade 6 injuries at T1 and none had this type of injury at T2 or T3. In conclusion, the results indicate that a specifically designed exercise programme can help to diminish the risk of shoulder injuries in tennis players. It can also improve bi-lateral muscle strength in opposing muscle groups which are used in tennis. / Thesis (DPhil)--University of Pretoria, 2007. / Biokinetics, Sport and Leisure Sciences / unrestricted

In South Africa all the major categories of violent crime (homicide, aggravated robbery, serious assault and rape) showed an increase during the early 2000s. More than half of the total offences that were committed in South Africa during 2005 were aggressive offences. The goal of the study was to explore the perception of offenders regarding the triggering and contributing socio-economic factors to aggravated robbery with a view to inform rehabilitation and re-integration programmes for these offenders. Within the context of the interrelatedness of socio-economic factors such as poverty, inequality, unemployment and human rights, developmental social welfare and its underpinning theory of social development was an appropriate theoretical framework for the study. A qualitative research approach was utilised for the study and data was gathered by means of semi-structured interviews. Respondents for the study included maximum-term offenders that were serving an imprisonment sentence for aggravated robbery. The research findings indicate a reciprocal relationship between poverty, inequality, unemployment, intoxicating substances and intra- and interpersonal factors as possible triggering and contributing factors to aggravated robbery. Unemployment, which is exacerbated by a lack of education and skills development and linked to intra- and interpersonal factors, appears to be a dominant socio-economic factor that could contribute to or trigger aggravated robbery. The study concluded that rehabilitation programmes still lack a holistic, integrated developmental approach and hence do not prepare ex-offenders for full integration into society. The Department of Correctional Services was pointed out as a significant role-player in facilitating rehabilitation programmes that include skills development for job creation in a holistic, integrated developmental manner. Recommendations include that the Department of Correctional Services should seek partnerships and closer working relations with external service providers, and develop and implement integrated developmental rehabilitation programmes that will facilitate the creation of productive economic opportunities for offenders while they are still incarcerated and once they have been released back into the community. / Dissertation (MSW)--University of Pretoria, 2012. / Social Work and Criminology / unrestricted

The objective of this study was to investigate and analyse the educators’ experience in managing a full-time school within a Correctional Services environment. Provision of education in the South African Department of Correctional Services is in terms of Section 29 (1) of the Constitution of the Republic of South Africa (Act No.108 of 1996) which stipulates that “everyone has a right (a) to basic education, and (b) to further education, which the state, through reasonable measures, must make progressively available and accessible.” “This constitutional imperative for schooling is not a right that is curtailed by incarceration” (DCS, 2005:137). The researcher used qualitative research inquiry. This is a case study of the educators’ experience in managing a full-time school within a Correctional Services environment. To obtain an in-depth understanding and gain more insight on the research topic, this study focused on one full- time school within the South African Department of Correctional Services. Literature reveals that “correctional centres are bureaucratic institutions that are characterised by a number of factors that can potentially encourage or impede education programme success” (Sanford &Foster, 2006:604). The environment makes learning difficult as there are frequent lockdowns, headcounts and hearings that disrupt the consistency of classes and interrupt the education process (Schirmer, 2008:29). Few learners attend classes and whilst in class they are not really listening, instead, they would be sleeping and unproductive. In most cases, learners would be present because they were forced to be in the education programme (Wright, 2004:198). In this study, the researcher used semi-structured one on one interviews, and document analysis as data collection strategies. Purposeful sampling was utilized to select respondents. A total of six respondents who are full-time educators employed by the Department of Correctional Services were interviewed. The study reveals that managing a full-time school within a Correctional Services environment seems to be challenging because education is not respected and not prioritized. This finding appears to be consistent with literature which reveals that the uniqueness of correctional centre culture with a correctional centre management characterized by a focus on security measures such as lockdowns and head counts constraints the possibilities of learning (Watts, 2010:57). Based on the findings in this study, the researcher recommends that educator development should be prioritized within the Department of Correctional Services and school management should be informed about learners that are released from the correctional centre. This study concludes that managing a full-time school within a Correctional Services environment is challenging due to Correctional Services environment being not conducive for teaching and learning and inadequate resources. / Dissertation (MEd)--University of Pretoria, 2013. / gm2014 / Education Management and Policy Studies / unrestricted
