- Description: Heat-related illnesses, which range from heat exhaustion to heatstroke, affect thousands of individuals worldwide every year and are characterized by extreme hyperthermia with the core body temperature (CBT) usually > 40 °C, decline in physical and athletic performance, CNS dysfunction, and, eventually, multiorgan failure. The measurement of CBT has been shown to predict heat-related illness and its severity, but the current measurement methods are not practical for use in high acuity and high motion settings due to their invasive and obstructive nature or excessive costs. Noninvasive predictions of CBT using wearable technology and predictive algorithms offer the potential for continuous CBT monitoring and early intervention to prevent HRI in athletic, military, and intense work environments. Thus far, there has been a lack of peer-reviewed literature assessing the efficacy of wearable devices and predictive analytics to predict CBT to mitigate heat-related illness. This systematic review identified 20 studies representing a total of 25 distinct algorithms to predict the core body temperature using wearable technology. While a high accuracy in prediction was noted, with 17 out of 18 algorithms meeting the clinical validity standards. few algorithms incorporated individual and environmental data into their core body temperature prediction algorithms, despite the known impact of individual health and situational and environmental factors on CBT. Robust machine learning methods offer the ability to develop more accurate, reliable, and personalized CBT prediction algorithms using wearable devices by including additional data on user characteristics, workout intensity, and the surrounding environment. The integration and interoperability of CBT prediction algorithms with existing heat-related illness prevention and treatment tools, including heat indices such as the WBGT, athlete management systems, and electronic medical records, will further prevent HRI and increase the availability and speed of data access during critical heat events, improving the clinical decision-making process for athletic trainers and physicians, sports scientists, employers, and military officers. © 2022 by the authors.

- Description: Objective There is a growing focus on ensuring the availability of automated external defibrillators (AED) in sport settings to assist in preventing sudden cardiac death. For the AED to be most effective, understanding how best to integrate it with wider risk management and emergency action plans (EAP) is needed. The aim of this survey was to identify sports club/facility member knowledge of AED use and club EAPs, 6 months following participation in a government-funded AED provision and cardiopulmonary resuscitation training programme. Methods Cross-sectional survey of community sports clubs and facilities in Victoria, Australia. Included participants were members of sports club/facilities that had been provided with an AED and basic first aid training as part of a government programme to increase access to, and awareness of, AEDs. A descriptive analysis of availability of EAPs and AEDs, together with practical scenarios on AED use and maintenance, is presented. Results From 191 respondents, more than half (56%) had no previous training in AED use. Knowledge on availability of an EAP at the club/facility was varied: 53% said yes and knew where it was located, while 41% did not have, or did not know if they had, an EAP. Responses to clinical scenarios for use of AED were mostly accurate, with the exception of being unsure how to respond when 'participant falls to the ground and is making shaking movements.' Conclusions While there were positive outcomes from this programme, such as half of the respondents being newly trained in emergency first aid response, further improvements are required to assist members with embedding their AED into their club/facility EAP and practices.

- Description: Objectives Exertional heat illnesses (EHI) can occur when sport is played in hot and humid environments, such as those common across Asia. Measures to reduce the risk of EHI are important; however, causal data on EHI occurrence are limited and challenging to capture. To gain an initial understanding of EHI risks, we aimed to assess the risk perceptions of EHI of youth cricketers. Methods A descriptive cross-sectional survey, comprised of 14 questions on EHI risks, was conducted with 365 Sri Lankan junior male cricketers (age=12.9±0.9 years) who typically play in hot and humid conditions. Results For climate related risks, relative humidity was perceived as having a low risk of EHI compared with ambient temperature. The EHI risk associated with wearing protective gear, as commonly used in cricket, was perceived as low. Most junior cricketers perceived a low level of risk associated with recommended preventive measures such as body cooling and heat-acclimatisation. Conclusion This is the first study to explore EHI risk perceptions in any sporting context. Young players may not be mindful of all risks. Therefore, leadership and initiative from competition organisers and parents is required to promote countermeasures.

- Description: BACKGROUND. Hamstring strain injuries (HSI) are among the most common injuries in field-based team sports with a high-speed running component. The implementation of the Nordic hamstring exercise (NHE) is a well-documented method of improving eccentric hamstring strength to mitigate the risk of HSI occurrence. Sprint training is specific to the injury mechanism and is thought to activate the hamstrings through maximal eccentric contractions. The purpose of this study was to compare the effects of sprint training and the NHE on eccentric hamstring strength and sprint performance. METHODS. Twenty-eight participants (mean +/- SD age=16.21 +/- 1.34 years; height=1.75m +/- 0.10m; body mass=68.5kg +/- 12.1kg) completed an eccentric hamstring strength assessment and 40m sprint to assess acceleration and maximum speed. Participants were randomly allocated to either a NHE training or sprint training group. Two sessions per week for four-weeks of training was performed with baseline testing procedures repeated in the week following the intervention. Perceptions of soreness were recorded following the warm-up in each training session. RESULTS. Both the NHE (effect size=0.39, P<0.05) and sprint training (effect size=0.29, P<0.05) groups displayed significant gains in eccentric hamstring strength. The NHE group reported trivial improvements in sprint performance, whilst the sprint training group experienced a moderate improvement, specifically in maximum speed (ES=0.83 Moderate). Sprint training also produced greater perceptions of soreness than the NHE following a four-week training intervention, specifically before the start of the last session (P<0.05). CONCLUSIONS. These findings indicate that sprint training had a beneficial effect for both eccentric hamstring strength and sprint performance, whilst also producing greater soreness than the NHE following the final training session. It was concluded that a four-week block of maximum speed training may have both an injury prevention and performance enhancement benefit.

- Description: Objectives Rugby-related spinal cord injuries (SCIs) are rare but life altering and traumatic events. Little is known about the long-term consequences and outcomes of players who have sustained these injuries. This study investigated current quality of life (QoL) and factors associated with QoL, among individuals with rugby-related SCI in South Africa, by using the International Classification of Functioning, Disability and Health (ICF) framework. Design Descriptive cross-sectional study. Setting Rugby-related SCI population of South Africa, as captured in the BokSmart/Chris Burger Petro Jackson Players' Fund database. Participants Ninety (n=90) of the 102 eligible players on the database agreed to participate in the study. Main outcome measure The relationship between QoL, as measured with the WHO Quality of Life questionnaire (WHOQOL-BREF) and specific independent variables (demographic information, level of independence and participation in various activities and life roles) was investigated. Variables that were significantly associated with QoL in bivariate analyses were included in multiple linear regression analyses. Results The mean score and SD of the WHOQOL-BREF was 15.1±2.3 arbitrary units. Participation (an ICF framework construct) and income were significantly associated with overall QoL (p<0.001). Participation was the only variable significantly associated with all QoL subdomains (p<0.001). Additionally, number of health concerns, type of healthcare (public vs private) and level of education were significantly associated with various QoL domains (p<0.001). Conclusions On average, these individuals with rugby-related SCI presented with higher QoL scores than other comparable SCI studies. However, lower levels of participation and income, certain levels of education, increased health concerns and use of public healthcare were associated with lower levels of QoL. Sporting bodies have a responsibility to optimise player welfare, by acting on the modifiable factors associated with QoL.

- Description: Aim To describe the acceptability and the perceptions of athletes and staff members (ie, end-users) towards an online sports-health surveillance system. Methods A pilot study with a mixed-methods approach was pursued. Descriptive analysis was conducted to present the adherence of judo (n=34), swimming (n=21) and volleyball (n=14) athletes to an online registration of their sport exposure and any health complaints between April 2014 and January 2015. End-users' perceptions towards the system were investigated qualitatively with semistructured interviews (n=21). Qualitative analysis was based on the constant comparative method using principles of the grounded theory. Results The response rates of judo, swimming and volleyball athletes were 50% (SD 23), 61% (SD 27) and 56% (SD 25), respectively. Most athletes found it simple to register their sport exposure and health complaints online; however, personal communication was still preferred for this purpose. The system facilitated the communication between medical and trainer staff, who were able to identify in the system reports health complaints from athletes that were not necessarily communicated face-to-face. Therefore, staff members reported that they were able to intervene earlier to prevent minor health complaints from becoming severe health problems. However, staff members expected higher adherence of athletes to the online follow-ups, and athletes expected to receive feedback on their inputs to the system. Conclusion An online system can be used in sporting settings complementary to regular strategies for monitoring athletes' health. However, providing feedback on athletes' inputs is important to maintain their adherence to such an online system.

- Description: Objectives: Various definitions for concussion have been proposed, each having its strengths and weaknesses. We reviewed and compared current definitions and identified criteria necessary for an operational definition of sports-related concussion (SRC) in preparation of the 5th Concussion Consensus Conference (Berlin, Germany). We also assessed the role of biomechanical studies in informing an operational definition of SRC. Design: This is a systematic literature review. Data sources: Data sources include MEDLINE, Embase, Cumulative Index to Nursing and Allied Health Literature, Cochrane Central Register of Clinical Trials and SPORT Discus (accessed 14 September 2016). Eligibility criteria for selecting studies: Eligibility criteria were studies reporting (clinical) criteria for diagnosing SRC and studies containing SRC impact data. Results: Out of 1601 articles screened, 36 studies were included (2.2%), 14 reported on criteria for SRC definitions and 22 on biomechanical aspects of concussions. Six different operational definitions focusing on clinical findings and their dynamics were identified. Biomechanical studies were obtained almost exclusively on American football players. Angular and linear head accelerations linked to clinically confirmed concussions demonstrated considerable individual variation. Summary/conclusions: SRC is a traumatic brain injury that is defined as a complex pathophysiological process affecting the brain, induced by biomechanical forces with several common features that help define its nature. Limitations identified include that the current criteria for diagnosing SRC are clinically oriented and that there is no gold/standard to assess their diagnostic properties. A future, more valid definition of SRC would better identify concussed players by demonstrating high predictive positive/negative values. Currently, the use of helmet-based systems to study the biomechanics of SRC is limited to few collision sports. New approaches need to be developed to provide objective markers for SRC. © Article author(s) (or their employer(s) unless otherwise stated in the text of the article) 2017. All rights reserved.

- Description: BACKGROUND: Head injuries, particularly concussion, are a major cause of concern in many sports, particularly the football codes, driving a need to better understand injury mechanisms and potential methods of prevention. The aim of this study was to describe the mechanisms and follow up care of concussion injuries sustained in adult male community Australian football to identify target areas for prevention and management. METHODS: Secondary analysis of injury data collected in a cluster randomised controlled trial in community Australian football across two states of Australia in 2007 and 2008. There were 1564 players from 18 clubs. The main outcome measures were the number and rate of head/neck/face (HNF) injuries and concussion sustained in games. A specific description of the mechanisms of the concussion injuries is presented along with the immediate return-to-play status of concussion cases. RESULTS: 143 HNF injuries were sustained by 132 players. The game HNF injury incidence was 4.9 per 1000 game hours (n = 138; 95 % confidence interval 4.1; 5.7). Just under a quarter (n = 34) of all HNF injuries were recorded as concussion. All concussions occurred during games (none in training), with all but one related to body contact with other players. Overall, 68 % of the concussions were considered within game rules, while 32 % were either outside of the rules or unclear. Most (88 %) players left the field immediately following concussion but 47 % later returned to play in the same game. CONCLUSIONS: Prevention strategies for concussion need to be based on knowledge of the mechanisms of injury. Most concussions in community Australian football occurred through body contact with other players or during tackling. Management of players post-concussion was generally poor with over half of the cases continuing to play in the same game. Therefore, new primary prevention strategies that target body-contact/tackling skills and improved secondary prevention measures relating to compliance with return-to-play protocols would be valuable.

Most concussions in community Australian football occurred through body contact with other players or during tackling. Management of players post-concussion was generally poor with over half of the cases continuing to play in the same game. Therefore, new primary prevention strategies that target body-contact/tackling skills and improved secondary prevention measures relating to compliance with return-to-play protocols would be valuable.

- Description: Objective: To compare Orchard Sports Injury Classification System (OSICS-10) sports medicine diagnoses assigned by a clinical and non-clinical coder. Design: Assessment of intercoder agreement. Setting: Community Australian football. Participants: 1082 standardised injury surveillance records. Main outcome measurements: Direct comparison of the four-character hierarchical OSICS-10 codes assigned by two independent coders (a sports physician and an epidemiologist). Adjudication by a third coder (biomechanist). Results: The coders agreed on the first character 95% of the time and on the first two characters 86% of the time. They assigned the same four-digit OSICS-10 code for only 46% of the 1082 injuries. The majority of disagreements occurred for the third character; 85% were because one coder assigned a non-specific 'X' code. The sports physician code was deemed correct in 53% of cases and the epidemiologist in 44%. Reasons for disagreement included the physician not using all of the collected information and the epidemiologist lacking specific anatomical knowledge. Conclusions: Sports injury research requires accurate identification and classification of specific injuries and this study found an overall high level of agreement in coding according to OSICS-10. The fact that the majority of the disagreements occurred for the third OSICS character highlights the fact that increasing complexity and diagnostic specificity in injury coding can result in a loss of reliability and demands a high level of anatomical knowledge. Injury report form details need to reflect this level of complexity and data management teams need to include a broad range of expertise. Copyright Article author (or their employer) 2012.

- Description: There is increasing concern in Australia about safety in the thoroughbred racing industry, but there has been no reported analysis of injury data. This review analyses injury and workers' compensation data recorded in Victoria. On the basis of the results, it is recommended that the injury and incident data collection systems are improved such that they are not only more complete but also accumulate more detailed information about the location of an incident or injury event, the activity at the time of the incident or injury event, and factors that may have influenced the occurrence.
