This study aimed to record the medical history, illness and injuries of athletes receiving medical attention during the 2014 Ironman South Africa (IMSA) triathlon, and to investigate the temporal presentation of medical encounters.<span class="Apple-converted-space">&nbsp;</span></p> <p><strong>Methods: </strong>This was a retrospective, cross-sectional study. All athletes who required medical attention at the main medical tent and all of the medical posts or mobile units along the route were included in this study A total of 2 331 athletes started the race. Data included age, gender, time and stage of the race when medical attention was required, pre-race medical history and medication use, illness and injuries treated, special investigations performed, and weather conditions.<span class="Apple-converted-space">&nbsp;</span></p> <p><strong>Results: </strong>Overall, 179 athletes (7.7%) required medical attention. The incidence of medical encounters was 7.8%. A significantly higher percentage of younger participants encountered medical problems (<em>P </em>= 0.04). Most patient encounters (80.1%) occurred after the race. The median duration of treatment was 26 minutes. Medication was used by 35.1% of patients during the race. The most common medical encounters were exertion-related (71.2%), gastro-intestinal (16.4%), dermatological (11.9%), musculoskeletal (9.6%) and cardiorespiratory conditions (2.4%).<span class="Apple-converted-space">&nbsp;</span></p> <p><strong>Conclusion: </strong>Medical encounters occurred more frequently in later stages of the race. Most medical conditions were exertion-related. Potential higher risk may be associated with medication use, recent illness, and in younger participants. Temporal stacking of medical personnel, planning of resources according to expected conditions, preventative measures for high-risk behaviour, and on-going data collection with comparable methodology are recommended.<span class="Apple-converted-space">&nbsp;</span></p> L Holtzhausen ##submission.copyrightStatement## 2018-03-26 2018-03-26 30 1 1 6 Concussion knowledge and attitudes amongst Stellenbosch University hostel rugby players https://journals.assaf.org.za/index.php/sajsm/article/view/4924 <p>&nbsp;</p> <p><span class="Apple-converted-space">&nbsp;</span><strong>Background: </strong>Concussion occurs more frequently in contact sports, such as rugby, and is furthermore not fully recognised during play. It is also underreported in the literature, to medical personnel, or to coaches.<span class="Apple-converted-space">&nbsp;</span></p> <p><strong>Objectives: </strong>The objective of this study was to describe the knowledge about and attitudes towards concussion by Stellenbosch University hostel rugby players.<span class="Apple-converted-space">&nbsp;</span></p> <p><strong>Methods: </strong>The study focussed on gathering quantitative information through implementing a cross-sectional study design. One hundred and eighty Stellenbosch University hostel rugby players completed the modified Rosenbaum Concussion Knowledge and Attitudes Survey - Student Version (RoCKAS-ST). The RoCKAS-ST questionnaire is divided into three parts, namely, the evaluation of the Concussion Knowledge Index (CKI) and Concussion Attitudes Index (CAI), and a 16-symptom checklist.<span class="Apple-converted-space">&nbsp;</span></p> <p><strong>Results: </strong>The participants scored on average 75% in the CKI and 81% in the CAI. The correlation between CKI and CAI was r=0.14 which is considered a weak positive correlation.<span class="Apple-converted-space">&nbsp;</span></p> <p><strong>Discussion: </strong>The participants demonstrated sufficient knowledge of concussion and thus a safer attitude towards concussion. There were some concerning factors from the knowledge of the concussion questions and the symptoms that may have an effect on attitudes towards concussion.<span class="Apple-converted-space">&nbsp;</span></p> <p><strong>Conclusion: </strong>The study revealed that Stellenbosch University hostel rugby players have sufficient knowledge of what constitutes concussion, as well as the necessity of having safe attitude towards it. However, a small number of participants showed that they still may lack knowledge in certain areas concerning concussion.<span class="Apple-converted-space">&nbsp;</span></p> W Kraak ##submission.copyrightStatement## 2018-03-26 2018-03-26 30 1 1 5 A cross-sectional study of 2550 amateur cyclists shows lack of knowledge regarding relevant sports nutrition guidelines https://journals.assaf.org.za/index.php/sajsm/article/view/4940 <p>&nbsp;</p> <p><span class="Apple-converted-space">&nbsp;</span><strong>Background: </strong>Amateur cyclists use a wide variety of supplements and nutritional substances to increase performance in addition to their training.<span class="Apple-converted-space">&nbsp;</span></p> <p><strong>Objectives: </strong>The intended nutritional supplement use, carbohydrate (CHO) use and hydration practices of amateur cyclists before, during and after endurance cycling were analysed.

These injuries may lead to significant absence from activity with an associated financial and social burden. No definitive association has been described between mechanism of injury and pathology to enable us to put preventative measures in place in order to limit these injuries.</p> <p><strong><em>Aim</em></strong></p> <p>To determine whether there is an association between the mechanism of injury and the pathology seen on a magnetic resonance imaging (MRI) scan in anterior cruciate ligament (ACL) injuries.</p> <p><strong><em>Methods</em></strong></p> <p>This was a cross-sectional analytical study. Eighty seven male patients with an ACL injury, who had an MRI scan of the knee within the last two years participated in this study. Participants were contacted to give consent that their information be used in this study. The mechanism of injury and the pathology seen on the MRI scan was noted and categorised into different mechanism of injury groups and associated pathology groups. Statistical analyses included summaries of the data and a test for association between mechanism of injury and pathology. Since there were multiple pathology responses to each mechanism, a modified version of the chi-square test for independence was used. A 5% level of significance was specified.</p> <p><strong><em>Results</em></strong></p> <p>MRI scans of ACL injuries indicated that the mechanism of a solid foot plant with rotation of the knee has a greater tendency to be associated with medial meniscal injuries (77%), and also a 54% possibility to be associated with lateral meniscal injuries. A solid foot plant with a valgus stress on the knee showed a higher incidence of associated medial collateral ligaments (MCL) injuries (41%) and femoral bone bruising (62 %). These two mechanisms of injury are the most common in ACL injuries and contribute to the clinical significance found in this study. The p-value was however not statistically significant (p=0.44, chi-square value=20.27, df=45) for any association between pathology and mechanism of injury.</p> <p><strong><em>Conclusion</em></strong></p> <p>Some injury mechanisms causing ACL injury were more common than others and also had more associated pathology. The most common mechanism of injury noted is a solid foot plant with either rotation of the knee or valgus stress on the knee. Strengthening tissue structures involved in those movement patterns that cause these mechanisms can possibly limit ACL injuries in athletes and the general public.</p> <p>&nbsp;<strong><em>Key words</em></strong></p> <p>Anterior cruciate ligament injury, mechanism, association, pathology, MRI scan, prevention.</p> G Linde Strauss ##submission.copyrightStatement## 2018-09-10 2018-09-10 30 1 1 6 10.17159/5265 The impact of anterior knee pain on the quality of life among runners in Ekurhuleni, Gauteng https://journals.assaf.org.za/index.php/sajsm/article/view/4947 <p><strong>Background: </strong>Anterior knee pain (AKP) is the most common injury among runners and has a negative impact on the quality of life (QOL) of many athletes. <strong>Objective:</strong> To determine the impact of anterior knee pain on the QOL among runners in Ekurhuleni, Gauteng. <strong>Materials &amp; methods: </strong>A cross–sectional study design was used. A population of 73 runners with AKP were included. Participants included runners aged 13 to 55-year-old. The SF-36 questionnaire was used to collect data. Ethical clearance, permission from club managers and consent from participants were obtained. Data were collected over six weeks and analysed using SPSS. Descriptive statistics included frequencies, means, standard deviations and ranges. Inferential statistics included Spearman's correlation calculation. <strong>Results: </strong>The lowest QOL scores were found among: role functioning/physical (62), role functioning/emotional (59), energy/fatigue (59), emotional well-being (68) and pain scales (63). Males, youth and runners with least experience presented with lowest scores.

Players were categorised as follows: central defenders (CDs), wide defenders (WDs), central midfielders (CMs), wide midfielders (WMs), and attackers (ATs). Match activities were captured using a validated camera tracking system (InStat®).</p> <p><strong>Results:</strong> The findings showed that total distances covered by players during matches consistently decreased by 13% from the first half of the game (112.79±10.17&nbsp;m) to extra time (103.17±6.39&nbsp;m). The reduction of the total distance covered, especially in high-intensity running (i.e., high-speed running and sprinting), was more apparent in ATs than players in other positions.</p> <p><strong>Conclusion:</strong> Intervention strategies needed to sustain soccer players’ physical performance during extra-time periods and of post-match recovery modalities warrant further investigation.</p> A Kubayi ##submission.copyrightStatement## 2018-11-05 2018-11-05 30 1 1 3 10.17159/4842 A four-week home-based exercise programme is effective in treating subacute low back pain in adults https://journals.assaf.org.za/index.php/sajsm/article/view/5020 <p>Background: Low back pain (LBP) is a prevalent condition affecting a large portion of the population world-wide and it is one of the leading causes of morbidity and work absenteeism. <br>Objective: To investigate the effectiveness of a four-week, home-based exercise program in treating subacute LBP in adults.</p> <p><br>Methods: A quantitative, experimental research design was employed. Twenty male and female adults aged between 18 and 65 years with subacute LBP were recruited by means of advertisements and word of mouth and allocated into either a control group (CG) or a home-based exercise group (HG). Both groups underwent a pre-test that consisted of answering two questionnaires, the Visual Analogue Scale for Pain (VASP) and the Oswestry LBP and Disability Questionnaire. The (CG) received no intervention over the four-week intervention period, while the intervention group (HG) was given an exercise program and instructed to perform the exercises at home, three times a week for four weeks. After four weeks (post-test), the two questionnaires were repeated. After eight weeks (follow-up test) both groups again completed the two questionnaires. Descriptive statistics, non-parametric inferential statistics and Cohen’s effect size (d) were used to analyse the data and statistical significance was set at a confidence level of 95% (p?0.05).</p> <p><br>Results: Following the home-based exercise intervention there were significant improvements observed in lower back pain and function for the HG.

However, a certain level of physical fitness is required to execute these skills optimally. Coaches tend to give little focused attention to the development of physical fitness during training, which could lead to players being physically unprepared for the demands of a game.<span class="Apple-converted-space">&nbsp;</span></p> <p><strong>Objective: </strong>The purpose of this study was to assess and compare the physical demands of a one-day cricket game and a training session of provincial cricket players, using Global Positioning System units.<span class="Apple-converted-space">&nbsp;</span></p> <p><strong>Methods: </strong>Nineteen male provincial cricketers participated in the research. The participants were classified into five sub-disciplines, namely, batting, fast bowling, spin bowling, fielding and wicketkeeping. The study employed a descriptive and comparative design as it essentially collected numerical data from Global Positioning System units to describe and compare the physical demands of a one-day game of cricket and a training session preceding these games. The variables used in the study included total distances travelled in the game which were divided into five movement categories, i.e. walking, jogging, running, striding and sprinting.

Previous injury has been found to be one of the greatest risk factors associated with recurrent hamstring strains. Although rehabilitation programmes have been developed and implemented to aid safe and efficient return-to-play, the incidence of hamstring injuries has not decreased.&nbsp;</p> <p><strong>Discussion: </strong>As hamstring strains most commonly occur during the eccentric phase of muscle action, rehabilitation should focus on eccentric muscle strengthening. The L-protocol and the Nordic Hamstring Exercise protocol strengthen the hamstring muscles eccentrically. They have been found to be effective in decreasing the incidence of new hamstring strains as well as the rate of recurrence. This commentary therefore aims to suggest changes to the return-to-play criteria following hamstring strains to prevent the seemingly unpreventable.</p> N Craddock ##submission.copyrightStatement## http://creativecommons.org/licenses/by/4.0 2018-03-26 2018-03-26 30 1 1 2 Building a robust athlete in the South African high school system https://journals.assaf.org.za/index.php/sajsm/article/view/2933 <p>In the modern era of school sport, schools are faced with important decisions on how best to structure their programs to fit in the growing number of tournaments into the schools sports calendars. Furthermore, school sport has taken on a more professional and competitive feel, with the possibility of winning cash prizes as well as the live TV coverage of various tournaments it is plausible to believe that the pressure on coaches to win at this level has increased when compared to 10 years back.The intention of this article is not to disparage the South African school sport system but rather to create an understanding of best practice when considering high school athletes. As it has been the authors experience through working with numerous highs school athletes and presenting to various schools and educators on this topic that the current system or lack thereof is possibly not athlete-centered which may be detrimental to their development down the line<span style="font-size: 8.33333px;">.</span></p> W Lombard ##submission.copyrightStatement## 2018-07-06 2018-07-06 30 1 1 3 10.17159/2933 Neurologist at ringside-to be or not to be? https://journals.assaf.org.za/index.php/sajsm/article/view/4255 <p><strong>Background:</strong> Ringside physicians are entrusted with the task of protecting the health and safety of combat sports (boxing and mixed martial arts) athletes. Ringside physicians come from various disciplines of medicine such as primary care, Internal Medicine, orthopaedics, sports medicine and even otolaryngology. There are very few neurologists who work as ringside physicians.</p> <p><strong>Discussion:</strong> Boxing and MMA are highly controversial sports for neurologists to be involved in for in these sports every punch and kick to the head is thrown with the intention of knocking the opponent out. Every punch and kick to the head is thrown with the intention to win via causing a concussion. Many neurologists thus feel it is unethical to support boxing by working as a ringside physician.</p> <p><strong>Conclusion</strong>: Boxing and MMA are universally thought to be detrimental to the brain and nearly all medical associations at various times have made calls to ban boxing and MMA altogether. While medical associations and physicians including neurologists may not support boxing or MMA, the presence of a neurologist ringside or cageside helps make these sports safer by protecting the health and safety of a combat sports athlete.</p> N Sethi ##submission.copyrightStatement## 2018-07-27 2018-07-27 30 1 1 2 10.17159/4255 Sacroiliac tuberculosis masquerading as mechanical lower back pain in a collegiate basketball athlete: a case presentation https://journals.assaf.org.za/index.php/sajsm/article/view/5143 <p><strong>Background:</strong>Sacroiliac tuberculosis is a rare condition for which early diagnosis and effective management frequently proves challenging. This report describes a case that was initially overlooked due to its presentation and unreported constitutional symptoms.</p> <p><strong>Aim:</strong>To alert clinicians about skeletal tuberculosis, an often neglected diagnostic differential, which requires a high index of clinical suspicion, especially for patients from endemic areas.</p> <p><strong>Findings:</strong>This patient’s presentation (sports injury) and unreported constitutional symptoms resulted in a delay in the diagnosis and initial institution of treatment.</p> <p><strong>Implications:</strong>This report illustrates the importance of specifically asking about constitutional symptoms, even in sports injury settings and being mindful of infectious diseases or other chronic medical conditions, which may masquerade as common sports injuries.</p> M Moyaert ##submission.copyrightStatement## 2018-03-26 2018-03-26 30 1 1 3 The Currie Cup Premiership Competition Injury Surveillance Report 2014 - 2017 https://journals.assaf.org.za/index.php/sajsm/article/view/5720 <p>The content of the report is based on data collected by the SA Rugby Injury and Illness Surveillance and Prevention Project (SARIISPP) steering group.</p> L Starling ##submission.copyrightStatement## 2018-10-30 2018-10-30 30 1 1 42 10.17159/5720
