The influence of hind-foot bone size and shape on the scaling of joint surface area
Introduction: Despite the wide variation in the size and shape of humans and their feet, less is known about how our feet change shape with increasing size. The square-cube law states that if a bone grows isometrically, the surface area (SA) will grow at a slower rate than the volume (SA = volume^2/3), with either side of this termed allometry. Following isometric scaling, as bone and body mass increase in volume joint contact stress increases more rapidly (stress = force/SA). For example, someone with a talar dome joint surface area (JSA) of 18cm2 and body mass of 75kg will have an estimated pressure of 1.6MPa at heel str...

The joint effect of sleep and physical activity on low back pain
Introduction: Low back pain (LBP) is the highest contributor towards global disability. Previous studies have shown that lifestyle factors such as sleep and physical activity (PA) are associated with LBP. However, the possible synergistic effect of sleep and physical activity on LBP remains unknown. The aim of this study was to examine the joint association of sleep quality and PA on activity limitation due to LBP. (Source: Journal of Science and Medicine in Sport)

Socioeconomic status is associated with self-reported symptoms and function after anterior cruciate ligament reconstruction
Introduction: Socioeconomic status (SES) is known to contribute to healthcare access and recovery following many orthopaedic injuries and surgeries. For anterior cruciate ligament (ACL) injuries, a 2022 systematic review found low SES was associated with worse self-reported outcomes and higher complication rates post-ACL reconstruction (ACLR), but all data was from American studies. Given socioeconomic and healthcare system differences between countries, we aimed to determine if SES is associated with outcomes post-ACLR in Australia.

Evaluation of the intra- and inter-reliability of injury classification in Australian rugby union using video analysis
Introduction: Since the publication of a consensus statement in 2007, injury mechanism has been consistently collected. Rugby Australia developed the Australian Rugby Injury Surveillance System (ISS) aligned to the consensus. Injury surveillance systems are essential tools to collect information about the situation of injuries in sports. However, inconsistent applications of definitions, misapplication of coding the injury categories or recall bias, can appear. Recent evaluations have revealed that some injury mechanism information is not identified, which raises questions about the data's validity. (Source: Journal of Sci...

Exploring sex-differences in koos outcomes among runners with and without a history of knee surgery
Introduction: Following knee surgery, women experience worse self-reported knee-related outcomes (e.g. function and quality of life) compared with men. It is unknown if sex differences in self-reported knee-related outcomes are evident in higher-functioning people who have returned to running and continue to regularly run post knee surgery.

Essential EMG signals for modelling ACL forces: An ablation study
Introduction: Rupture of the knee ’s anterior cruciate ligament (ACL) is a common injury sustained during sport and recreation. Over the past two decades, rates of ACL have increased markedly, particularly so in young people and young females. New technologies have enabled quantification of ACL loading within the laboratory using EMG-driven neuromusculoskeletal modelling. However, to create a clinic- or field-friendly technology to quantify ACL loading, it is necessary to establish the number and combination of EMG signal that are essential for accurate modelling of the ACL load.

Quantifying Physical Activity and Self-Determination towards Exercise among Esports Players
Introduction: Esports is a rapidly growing industry, attracting millions of viewers worldwide and generating billions of dollars in revenue. Esports involves competitive video gaming, typically performed in teams or individually, across a range of genres, with large cash prizes at stake. While e-athletes require high levels of cognitive skill for successful performance, they spend extended periods in a sedentary state. This poses a challenge for maintaining physical activity and promoting exercise motivation within the industry, given the potential impact on general health and the burden on global healthcare.

Reliability testing of foot and ankle strength specific to Ballet using the ForceFrame and DynaMo
Introduction: Ballet movements are technically demanding, performed repetitively at extreme ranges of motion and somewhat unique, for example, standing en pointe. Overuse injuries are common in dancers, especially of the foot and ankle. Strengthening muscles that cross the ankle and metatarsal joints are fundamental for performing repetitive ballet repertoire and can reduce injury risk. Research is limited on the reliability of a portable device to assess ballet specific movements relating to the ankle while no reliable strength measure exists for the 1st and 5th metatarsal, which is considered highly relevant in ballet.

The multi-dimensional impacts of injury for women with insufficient activity levels
Introduction: Physical inactivity is a globally challenge, with a significant proportion of adults not meeting minimum recommended levels of physical activity (PA). Compared to men, women have lower rates of PA participation and experience unique barriers. Injury was recently identified as a major barrier to sport/PA participation for adults. However, for women who do not meet the minimum PA guidelines and who experience injury as a barrier to PA participation, the full impact of an injury remains unclear.

Immediate effects of rigid and elastic adhesive tape on pain in musculoskeletal and sports conditions: a systematic review and meta-analysis of randomised controlled trials
Introduction: Rigid and elastic adhesive tape are commonly used by clinicians when treating sports injuries and musculoskeletal conditions. While there are a plethora of studies investigating the effects of elastic and rigid tape on musculoskeletal conditions, previous studies have reported inconsistent findings on the effects of tape on pain. Importantly, the comparison between elastic and rigid tape remains equivocal. Hence, this meta-analysis aimed to compare the immediate effect of rigid, elastic, and no tape on pain in people with sports injuries and musculoskeletal conditions.

The relationship between lateral hip muscle morphology and hip-related quality of life in active young adults with hip/groin pain
Introduction: Hip/groin pain is a chronic condition that can impact daily life and sports participation. Identifying modifiable factors to help manage symptoms and improve outcomes is crucial. Recent research suggests that lateral hip muscle morphology (size and quality) can impact on optimal hip function and pain presentation. However, the association between hip muscle morphology and hip-related quality of life (QoL) in active young adults with hip/groin pain is unclear. The aim of this study was to investigate the association between the size and level of fatty infiltrate of lateral hip muscles with hip-related QoL meas...

“You never stop adjusting’: understanding player experiences of rugby-related spinal cord injury in Australia and opportunities to improve support
Introduction: Participation in sport provides many social, emotional and physical benefits, despite an inherent risk of injury. While many injuries are simply considered part of playing sport, those which result in death or permanent and disabling injuries are less acceptable. Rugby union is associated with a permanent spinal cord injury incidence rate of around 1 to 1.6 per 100,000 players. While this may seem low, these injuries hold very serious consequences for those players. Primary prevention of SCI in rugby remains a priority, however studies into the long-term outcomes for injured players are lacking. (Source: Jour...

Evaluation of an injury prevention program (Prep-to-Play) in 2713 women and girls playing community Australian Football: a hybrid implementation-effectiveness, stepped-wedge cluster randomised controlled trial
Introduction: Prep-to-Play, an injury prevention program for community women ’s football, was co-designed with the Australian Football League, adapted from effective programs in women’s soccer. Prep-to-Play online resources were distributed to all coaches in 2019, but coaches reported low confidence and limited support to use it. We aimed to compare Prep-to-Play use and injury rates between unsupported (online resources) and supported implementation in women’s community Australian Football.
