The information provided is by age group and playing position. The fitness of the players for South African and New Zealand netball is also given using the fitness normative data (normsMETHODS: This cross-sectional, descriptive study consisted of 77 elite South African netball players. Anthropometric measurements were taken according to international standards. Fitness tests included the Star Execution Balance Test, standing broad jump, double- and single-leg vertical jump, Yo-Yo Intermittent Recovery Level 1(IR1) test, sprints over 5, 10 and 40 m, horizontal pull-ups and press-ups, the prone bridge test and anaerobic Octorepeater tests with 10 m and 20 m repeated shuttle sprints. In keeping with the descriptive nature of the study, descriptive statistics were calculated for numerical data by age group and playing positionRESULTS: Players generally did not meet the accepted fitness standards in the following areas: press-ups (all age groups), horizontal pull-ups (senior and U21), standing broad jump (senior and U21), vertical squat jump (senior and U21), 5 m and 10 m sprints (senior and U21); anaerobic Octorepeater (senior players), and the aerobic Yo-Yo IR1 test (all age groupsCONCLUSION: Strength and conditioning coaches should develop training programmes to address fitness areas where players do not meet the international standards <![CDATA[<b>Nutritional supplements use, cost, source of information, and practices by Johannesburg North gym goers</b>]]> BACKGROUND: Nutritional supplements are defined as any dietary supplement manufactured product that is generally intended to supplement the diet when taken by mouth as a pill, capsule, tablet, or liquid. Currently, the use of nutritional supplements is on the increase worldwide, predominantly in Western countries but also more recently expanding to other parts of the world for what has become a multibillion-dollar global industry. As a result, consumer demand has caused the increase in the advertising and marketing of these products. This contributes to early exposure to nutritional supplements by potential consumers and is an influencing factor for the use of performance-enhancing and/or appearance substances by adolescents. For the nutritional supplement industry the container is thus the manifestation of innovative ideas for the enterprising business-minded mogul. For the consumer, body image and ideal body discrepancy, and social influences manifest in the belief that the perfection of body development cannot be achieved without the use of nutritional supplements. This makes the consumer a captive audience for the industry and a challenge for the health care provider when suggesting alternatives to nutritional supplements, based on cost-benefit, and risk assessmentOBJECTIVE: To determine the association between commercial gym goers and nutritional supplements, in particular the commencement of use, reasons and purpose for use, and the financial and risk implications of useMETHODS: A self-administered questionnaire based on a cross-sectional quantitative design and systematic convenience sampling was given to the 364 recruited males and female gym goersRESULTS: This study's finding shows that the main reasons why females attend gyms are for muscle gain (57%), weight loss (48%), staying healthy (47%), and a 'spiritual motive' (39%) In males, it is predominantly for muscle gain (54%). Protein supplements were the most popular products that were consumed (84%) followed by carbohydrates (72%) and vitamins (71%). It was found that the consumption of nutritional supplements often starts at high school age and continues into adulthood. The analysis shows that natural source protein products are better priced than nutritional supplement productsCONCLUSION: The study shows the importance of educating gym goers, the general public, and the guardians of minors to make a behaviour change towards nutritional supplement consumption. The change should also incorporate a cost-benefit risk assessment which is practical for the consumer when comparing supplement use as alternative sources of protein <![CDATA[<b>Experiences and rehabilitation needs of runners with anterior knee pain in under-resourced communities in Ekurhuleni, Gauteng, South Africa</b>]]> BACKGROUND: Anterior knee pain (AKP) is a common knee injury resulting from overuse, and impact negatively on the quality of life of many runners. Runners with AKP in under-resourced poor communities present with poor health outcomesAIM: To determine the experiences and rehabilitation needs of runners in under-resourced communities in Ekurhuleni, South AfricaMETHODS: The study was qualitative, based on the focus group interview method. Interviews were conducted with 12 runners. They were aged from 18 to 45 years and had a history of AKP. Permission was obtained from club managers and consent from each participant. An interview schedule with predetermined questions was used to collect the data. Two researchers conducted the interview, a facilitator and moderator. The interview session lasted for 80 minutes. Audio recordings of the interview session were made, transcribed verbatim and notes taken, with the final result provided in a written report. The data approach was thematic and deductive in natureRESULTS: All 12 recruited participants participated. The participants were comprised of six females and six males, eight youths and four adults; seven had <5 years of running experience and five had 10 years. The following themes and subthemes emerged: 1) The negative impact of AKP on health (physical, emotional and social); 2) Limited rehabilitation services (availability, accessibility, affordability, adequacy and appropriateness); 3) Rehabilitation needs (knowledge and professional interventionCONCLUSION: The study showed the negative impact of AKP on health and the problem of the paucity of rehabilitation services. A community based rehabilitation programme is therefore recommended for runners <![CDATA[<b>A "scattered" SCAT in a football goalkeeper: a case report</b>]]> BACKGROUND: In an acute field-side setting, it is often challenging to differentiate benign sports-related concussion (SRC) from potential, more sinister, intracranial pathology. Moreover, recovery in the ensuing days and weeks is often complex as the resolution of classical signs and symptoms does not always follow a standard patternAIM: To highlight the value of a structured and repeated thorough clinical assessment approach toward SRC, particularly as atypical and unexpected sequences in patient recovery patterns may require further specialist referral and interventionFINDINGS: A football goalkeeper sustained a concussion in which symptoms failed to resolve as expected. Deterioration in his clinical condition led to an eventual diagnosis of Chiari malformation (type I), which required surgical interventionIMPLICATIONS: Non-typical recovery patterns of concussion may be indicative of increased severity when considered retrospectively. However, clinicians should not discount the possibility of underlying conditions <![CDATA[<b>Changes in cardiorespiratory fitness and cardiovascular health in the workplace: a case study</b>]]> BACKGROUND: Cardiorespiratory fitness (CRF) is an independent predictor of cardiovascular (CV) and all-cause mortality, contributing a higher proportion of CV risk compared to other traditionally recognised risk factors. However, CRF is not included in usual workplace wellness protocols and, as such, employers are not aware of the importance of this factorAIM: The aim of this case study was to explore the effect of a 12-week exercise intervention programme on CRF, CV health and medical health claims in a male participant who was employed by a corporate company with existing chronic diseasesFINDINGS: Health outcome measures improved after the 12-week exercise intervention programme. CRF showed the greatest improvement and medical health claims were lowered during the three-month post-intervention periodIMPLICATIONS: CRF should be included as a health outcome measure in worksite wellness programmes and monitored <![CDATA[<b>Brace yourselves: esports is coming</b>]]> BACKGROUND: Competitive gaming (or esports) is an emerging phenomenon with a field of over 454 million fans globally. Despite its tremendous popularity and commercial support, esports is not widely understood. It is also disregarded as a reputable or credible form of competition. The International Olympic Committee (IOC) contends that esports may be considered a sporting activity, but this is limited to the basis of its sedentary nature and poor governanceDISCUSSION: These authors present evidence to inform and clarify misconceptions surrounding esports among the broader scientific community. They also encourage researchers to engage in further work into the phenomenon of competitive gaming with regard to health and performance, resulting in a better understanding of esports and guiding its development as a credible, competitive entity
