A few weeks ago an Italian court convicted seven weather scientists for manslaughter. Their crime? They failed to adequately warn residents before a tremor struck central Italy in 2009. More than 300 people were killed as a result of the quake. The scientists were sentenced to 6 years' imprisonment for giving 'inexact, incomplete and contradictory information' about whether small tremors felt in the weeks and months before the earthquake constituted grounds for a more serious warning about an impending earthquake. Although the scientists claimed that the science of tremors was not sufficiently reliable to predict earthquakes, the judge did not share this view.
The relationship between anxiety and shoulder injuries among South African university and club rugby players : original researchSource: South African Journal of Sports Medicine 24, pp 107 –111 (2012)More Less
Objectives. This correlational study investigated the relationship between competitive anxiety and shoulder injuries in a sample of club rugby players (N=112) from two universities and three suburban clubs.
Methods. The participants were asked to complete a biographical questionnaire and the Sport Competition Anxiety Test, while the injury history of the players for the 2012 season was obtained from the responsible health professions after consent was given. Group differences and a direct logistical regression were calculated to determine the relationship between injury and anxiety.
Results. The results indicated that rugby players who contracted a shoulder injury in a 1-year season have significantly higher levels of anxiety than those players who did not. However, the effect size of the difference seems to be small. The anxiety levels of players with shoulder injuries were regarded as too high when competing. A logistical regression, including various factors, was able to predict injury fairly well, but anxiety seems to be the only variable that contributed significantly to the model.
Conclusion. The results suggest that the contribution of anxiety to the occurrence of shoulder injuries in club and university rugby cannot be ignored. The high level of anxiety associated with players who suffered shoulder injuries has to be targeted with anxiety management skills as part of a player development and injury management programme.

Background. The global mandate by the WHO World Health Report of 2002, Global Strategy for Diet, Physical Activity and Health, were mirrored by the policy environment in South Africa. The 'Vuka South Africa - Move for your Health' campaign was an example of an initiative adopted by national government, promoting physical activity (PA) for health.
Methods. This manuscript describes the process, events and lessons learned during the initial phase of Vuka SA from 2004 to 2010. Data were obtained from the grey literature, minutes and reports of meetings and from stakeholders.
Results. Utilising a multi-sectoral approach, this initiative was partnered by governmental and non-governmental organisations, the private sector and tertiary institutions. The main anticipated short-term outcome was an increased awareness of the message ('move for your health'), with a view to achieving increased population levels of participation in health-enhancing physical activity over the long term. Vuka SA was initiated by the National Department of Health and launched in 2005. Subsequently, 36 partner organisations participated in two national workshops, who together with provincial health promoters undertook to promote the campaign. This was followed by an international training course on PA and public health for policy makers and programme implementers, and the subsequent call for the development of an African Physical Activity Network.
Discussion. Although the campaign has not yet undergone rigorous evaluation and participation at present appears to be modest, there are promising examples of multi-sectoral awareness and advocacy activities resulting in some national dissemination of the role of PA in health promotion.

Participation in sporting activities carries an injury risk. Conversely, the increased awareness that physical inactivity is a major risk factor for disease has led government agencies and the medical community to encourage increased levels of physical activity. Many people will achieve this through participation in sport. Injury inevitably leads to a reduction in participation on a temporary or permanent basis, but the injury experience may also influence the lifelong physical activity behaviour. Few studies adequately examine the possible long-term consequences of sport participation after the competitive period has been completed, but by understanding the patterns of injuries in different sports one test can develop strategies to prevent and better manage the conditions that occur and promote lifelong physical activity. There is a need to develop models of understanding of injury risk at different life phases and levels of participation in a specific sport. The risk assessment of sport participation has to be relevant to a particular sport, the level of participation, skill, age and potential future health consequences. This article describes a sport-specific model which will improve guidance for coaches and healthcare professionals. It poses questions for sports physicians, healthcare providers, educators and for governing bodies of sports to address in a systematic fashion. Additionally the governing body, as an employer, will need to meet the requirements for risk assessment for professional sport and its ethical responsibility to the athlete.

Growing interest in producing expert performance, and increasing sport participation, has led to a number of models being proposed for optimal sporting development. Using physical or psychological developmental milestones as guidelines, these models in sport were aimed primarily at identifying key stages during childhood and adolescence, and to optimise training adaptation for the child to reach his/her full sporting potential. Taking into consideration the long-term developmental models, and the requirements to succeed in rugby, this review aims to prescribe the trainability of junior rugby players using a scientifically evidence-based long-term player development approach. As there have been several recent and comprehensive reviews of the literature on trainability during childhood and adolescence, the aim of this paper is to resynthesise the material and apply it to rugby. Although athlete developmental models suggest that the appropriate application of training stimulus during specific periods in childhood and adolescence will influence athletic potential, recent available literature contends that this concept is inconclusive and requires further investigation.

There is little consensus on the diagnosis, pathophysiology, investigation and management of groin injuries. A key factor in making the correct diagnosis is to firstly understand the anatomy and likely generators of pain in the region. This requires an understanding of the two joints in the pelvis - the hip joint and the pubic symphysis - which are at the centre of many movements. There are a multitude of varying studies on this topic. However, most importantly, many of the groin/hip pathologies can be averted by thorough and specific prehabilitation, bearing in mind the entire kinetic chain and addressing total function above and below the pelvis.

Acute corticosteroid-induced rhabdomyolysis is a rare, but potentially life-threatening, condition that deserves the attention of medical professionals and sport scientists. Early diagnosis is vital in minimising the secondary damage caused by rhabdomyolysis. This case of rhabdomyolysis highlights the severity of symptoms and the importance of decisive treatment. Clinicians should be familiar with the most common symptoms of acute corticosteroid-induced rhabdomyolysis to enable early diagnosis and efficient management of this condition.

I have always had an interest in endurance sports and have been fortunate enough to work with endurance athletes while completing my PhD. Professor Mujika is a well-respected scientist who, apart from his research work, consults with many elite endurance athletes. I was surprised at how excited I was to review a 'textbook'. Professor Mujika has assembled an 'all-star' cast of contributors world-wide, many of whom are well-known experts in their respective fields.
