Abstract:

Background: Injury and illness surveillance helps establish the infrastructure to provide adequate medical support at regattas and is the foundation for developing prevention strategies.

Objectives: To assess the prevalence and characteristics of injuries in the 4 weeks before the start of the 2022 World Rowing Beach Sprints Finals (WRBSF) (the 'Prevalence Survey') and describe the incidence and nature of new-onset injuries and illnesses incurred during the WRBSF (the 'Incidence Survey').

Methods: Athletes completed: (1) a prevalence survey recording injuries the 4 weeks before the WRBSF and (2) a recording of injuries and illnesses that occurred during the 3-day regatta.

Results: Fifty-nine of 152 eligible WRBSF athletes completed the prevalence injury survey. Twenty-three (38.9%) reported experiencing at least one injury within the 4 weeks before the WRBSF. The most prevalent anatomical injury sites were the forearm (11.86%), lumbar spine (10.17%), knee (8.47%), ankle (6.78%) and hand/fingers (6.78%). During the competition, only two illness occurrences were reported; both were respiratory infections. Two athletes reported injuries: a hamstring strain and a concussion.

Conclusion: Rowers presenting to the WRBSF described injuries leading up to the event that were similar to those common in classic rowing. Rowers at the event suffered injuries of the lower limb that were different from classic rowing and may be related to the addition of running to this event. An event concussion should be considered as a more likely injury in this type of rowing and future events should be prepared to manage such an injury.

Abstract:

Objective: To determine risk factors for second anterior cruciate ligament (ACL) injury following primary ACL reconstruction (ACLR) using return-to-sport (RTS) tests consisting of qualitative and quantitative measures in young athletes.

Methods: A case-control study design was used, and a retrospective review of adolescent athletes after primary ACLR was performed. All athletes completed an RTS test consisting of qualitative and quantitative assessments and psychological assessments with the Tampa Scale of Kinesiophobia. Athlete demographics, surgical characteristics and sports participation were also examined. A binary logistic regression was performed to verify an independent association between risk factors and second ACL injury using adjusted OR (aORs), 95% CI and p<0.05.

Results: In 72 eligible athletes, 12 (16.7%) suffered a second ACL injury. The mean Tegner activity level was 8.4+1.1, and the mean time from ACLR to RTS test completion was 10.4+2.9 months. One variable that showed the lowest p-value in the preliminary analysis was entered into the binary logistic regression model, which resulted in that qualitative assessment of knee valgus during the sidestep cut was associated with second ACL injury (aOR=4.64, 95% CI: 1.18 to 18.23, p=0.03).

Conclusion: Athletes who demonstrated excessive dynamic knee valgus on the involved limb during the sidestep cut were approximately 4.6 times more likely to suffer a second ACL injury.

Background: Chronic pain among athletes is often misinterpreted as tissue damage resulting from sport. While researchers have started to examine neuropathic pain among athletes with spinal cord injury (SCI), there is a need to develop a deeper understanding of their neuropathic pain symptoms and experiences, to support the development of evidence-based pain management protocols.

Objectives: The primary purpose of this study was to describe neuropathic pain experienced by athletes with SCI. A secondary purpose was to compare athletes' neuropathic pain symptoms when measured by two different clinical pain assessment tools and describe their experiences when trying to communicate their neuropathic pain.

Methods: 47 athletes with SCI completed the International Spinal Cord Injury Pain Basic Data Set (V.2.0), Douleur Neuropathique 4 (DN4), and two open-ended pain questions over the telephone.

Results: 66% of participants reported experiencing moderate-intensity neuropathic pain (M_{pain intensity}=5.32±1.78) and mild-to-moderate pain interference with activities of daily living (M_{pain interference}=3.55±2.11) and sleep (M_{pain interference}4.68±2.92). Overall, participants reported significantly more neuropathic pain symptoms in response to DN4 questions (M=4.62±1.38) versus open-ended pain questions (M=2.13±1.08), p<0.001. Participants reported difficulty with identifying neuropathic pain, describing their pain symptoms and identifying pain locations.

Conclusion: Athletes with SCI reported moderate-intensity neuropathic pain. However, they struggled with communicating their neuropathic pain without being prompted with a list of symptoms. To guide the development of effective pain management strategies among athletes with SCI, future research should focus on developing knowledge products to improve awareness of common neuropathic pain descriptors among athletes with SCI and sports medicine personnel.

Our objective is to describe the development of evidence-based policy and practice recommendations for pregnant, postpartum and parenting Canadian high-performance athletes. A community-based participatory research approach was employed as the study design, and data were generated via a rapid review of existing sport policy for pregnant and postpartum athletes, followed by an extensive consultation and engagement process with key sport stakeholders via survey and one-on-one and group interviews. 102 sport stakeholders participated via the survey (n=56), individual and group interviews (n=33), and follow-up interviews (n=13). Individuals represented a range of summer/winter Olympic and Paralympic athletes, medical and support staff, National Sport Organisations and Sport Canada representatives. Seven evidence-based policy and practice recommendations were developed for Sport Canada decision-makers. Recommendations include the need for Sport Canada to (a) establish two new cards for pregnant and parenting athletes, (b) develop a policy to support pregnant, postpartum and parenting athletes, (c) create new funding sources for facilities that accommodate the needs of pregnant, postpartum and parenting athletes, (d) create new funding source for athletes to train and/or compete during infants' first year, (e) develop training and educational modules related to pregnant, postpartum and parenting athletes, (f) increase visibility of pregnant, postpartum and parenting athletes and (g) invest in research on high-performance sport participation during and following pregnancy. The collaborative processes employed in this research serve as a model for sports organisations to develop evidence-based policies and practices that can support pregnant, postpartum and parenting athletes.

Objectives: Insufficient physical activity (PA) has long been a global health issue, and a number of studies have explored correlates of PA to identify the mechanisms underlying inactive lifestyles. In the literature, dozens of correlates have been identified at different (eg, individual, environmental) levels, but there is little or no direct evidence for the mutual associations of these correlates. This study analysed 44 variables identified as theoretically and empirically relevant for PA to clarify the factors directly and indirectly associated with PA.

Methods: A cross-sectional survey dataset of 19 005 Japanese-speaking adults (mean age=53.50 years, SD=17.40; 9706 women) was analysed. The data encompassed demographic and anthropometric variables; self-reported PA levels; perceived social support and environments (eg, awareness of urban facilities for PA); psychological traits and health-behaviour characteristics (eg, personality, motivation, self-efficacy, decisional balance, process of change strategies); and technology use (eg, mobile health apps).

Results: Network analyses were performed to select meaningful associations (partial correlations) among variables, which identified nine variables directly positively associated with PA: job/employment status, self-efficacy, perceived social support, intrinsic motivation, stage of change, counter conditioning, self-reevaluation, environment and technology use. Indirect associations (two-step neighbourhood) were identified for 40 (out of 44) variables, implying that most of the known PA-correlates are associated with PA-at least indirectly.

Conclusion: These identified associations echo the importance of the multilevel perspective in understanding how people maintain (in)active lifestyles. Interventions for PA could have mixed-level targets, including intraindividual characteristics, social support and physical and digital environments.

Physical activity is essential to a healthy lifestyle for adults with spinal cord injuries (SCI). Although exercise is recognised as an important tool for improving the well-being and independence of people with SCI, most individuals do not engage in physical exercise. Traditional exercise programmes often require participation in rehabilitation centres or specialised facilities, making them less accessible for individuals with chronic SCI. Many people with SCI live in rural communities and other geographically isolated areas where access to fitness facilities and outdoor recreational areas involves long commutes or expensive transportation, which is one of the most common barriers to exercise reported by people with physical disabilities. Consequently, exercise remains an underused intervention for improving health and function in people with SCI despite its proven effects in reducing pain, fatigue, fall risk and other secondary health conditions. This pilot study evaluates the feasibility and acceptability of a home-based supervised exercise programme for individuals with chronic SCI. The study will be an interventional and prospective pilot study. People with SCI will participate in a 3-month home-based exercise programme. Primary outcomes will include adherence to the exercise programme, while secondary outcomes will encompass quality of life, functional capacity, musculoskeletal health and clinical parameters. The programme will be structured into 1-hour sessions, held twice weekly for 3 months, conducted online and in small groups. The results of this study could be relevant for future indications of the best setting and strategy to ensure adherence to physical activity.
