Summary: The study found that shoulder and trunk injuries, as well as injuries resulting from overuse mechanisms, are important areas of concern in swimming and diving. The overall injury rates were 1.78 per 1000 athlete-exposures for swimmers and 2.49 per 1000 AEs for divers. More participation in sports injury surveillance is needed to better understand and prevent injuries in collegiate women's swimming and diving teams.

Summary: This study investigated the incidence of lower extremity injuries in Japanese collegiate men's basketball players during the COVID-19 pandemic and found that the injury rate was significantly higher during the 2020-21 and 2021-22 seasons compared to previous seasons. Specifically, lateral ankle sprains, hamstring strains, jumper's knee, and stress fractures of the proximal fifth metatarsal were more prevalent. These findings highlight the importance of appropriate screening and specific training loads to prevent injuries during detraining periods.

Summary: The study found that most research focused on the relationship between cognitive performance, athletic performance, and injury rate in collegiate athletes and sleep, but studies using biomarkers and physiological measures or imaging were relatively few. Most studies indicated that poor sleep quality and quantity led to negative cognitive and academic outcomes.

Summary: A study analyzing injury data from the National Collegiate Athletic Association Injury Surveillance Program found that the overall injury rate for collegiate baseball athletes was 3.16 per 1000 athlete-exposures. Preseason injury rates were significantly higher than regular season rates. Common injuries included shoulder, arm or elbow, and hand or wrist injuries, with hamstring tear being the most reported specific injury.

Summary: The overall injury rate in NCAA men's lacrosse was 4.90 per 1000 athlete exposures, with competition injury rate higher than practice injury rate. The most reported injuries were concussions, ankle sprains, and hamstring tears, emphasizing the need for further attention on concussions and lower extremity injuries in this population.

Summary: The study identifies cost as the primary barrier to implementation of knee injury prevention programs (IPPs), with most non-users indicating that implementation should be the responsibility of non-coaching staff members. A team-based approach involving athletes, coaches, and non-coaching staff members may support long-term implementation of IPPs.

Summary: The NCAA has sponsored men's cross-country programs since 1938, and the sport has shown significant growth since then. Most reported injuries in men's cross-country are inflammatory conditions, strains, and sprains, with the highest rate of inflammatory conditions occurring in the preseason. Continued monitoring of competition injury rates and commonly reported injuries is necessary for future research.

Summary: This study synthesized published data on the incidence and outcomes of injuries in the National Basketball Association (NBA) and Women's National Basketball Association (WNBA). The most common orthopedic sports injuries in the NBA included concussions, hand fractures, lower extremity stress fractures, meniscal tears, and anterior cruciate ligament tears. High-quality prospective studies are needed to understand the impact of injuries on player performance and career length.

Summary: In former NFL players, self-reported sport-related concussion (SRC) history is associated with current health-promoting behaviors and self-reported measures of brain health. The study found that SRC history is linked to poorer cognitive function, symptoms of depression and anxiety, and emotional-behavioral dyscontrol, while exercise frequency and diet quality are associated with better functioning, and sleeping less than 6 hours per night is related to worse mental health outcomes.

Summary: This study found that the prevalence of stroke among former National Football League players aged >= 50 years was lower than the general population, with significantly increased risk among those with 10 or more prior concussions. The findings add to the evidence suggesting that traumatic brain injuries are associated with increased risk of stroke. Clinically, management of cardio- and cerebrovascular health may be pertinent to those with a history of multiple prior concussions.

Summary: This study found discrepancies in parents' knowledge of concussion symptoms between free-response item and scale-based measure, with some symptoms being less commonly identified in both. Future research should explore strategies to assist clinicians in measuring and assessing concussion symptom reporting and knowledge with parents and their children.

Summary: No significant association was found between subjective cognition and objective measures of cognitive functioning among former collegiate football players. However, a greater self-reported concussion history was inversely associated with subjective cognition. Distress was significantly related to all subjective cognition metrics as well as performance on delayed recall and verbal fluency. Sleep quality was only significantly related to timed visuospatial sequencing.

The results showed that there was no significant increase in the odds of LEMSKI after concussion, but higher odds of non-time loss (NTL) LEMSKI and lower odds of time loss (TL) LEMSKI were observed in football.

Summary: This study investigated the epidemiology of lateral ankle sprains in NCAA sports from 2014-15 to 2018-19 seasons, describing injury patterns in different sports and season segments. The study found that the highest incidence rate of lateral ankle sprains occurred in men's basketball, and competition-related injuries were more common than practice-related injuries. Preseason had the highest injury rate. Injury mechanisms differed between male and female athletes, with more player-contact mechanisms in males. Nearly half of all lateral ankle sprains resulted in time loss.

Summary: Transitioning from professional football life has significant implications for the health and well-being of former NFL players. This study examined the experiences of former NFL players during this transition, identifying factors that facilitated the process and factors that made it difficult. The most commonly reported facilitators were having a career transition plan/options and social support, while difficulties related to structure and identity were identified as challenges. These findings highlight targeted intervention areas to enhance the well-being of NFL players during their transition from sport.

Summary: The study aimed to assess whether pluralistic ignorance contributes to concussion underreporting. Through surveying 2,504 military service academy cadets, it was found that most cadets believed they were more willing to report a concussion than others, aligning with the phenomenon of pluralistic ignorance. Different demographic groups showed varying degrees of holding this belief.

Summary: Undiagnosed concussions can increase the risk of further injuries and prolong recovery time. Concussion education programs should focus on improving athlete concussion reporting by targeting athlete enjoyment and participation in the education process. Enjoyment of previous concussion education can moderate the improvement in concussion reporting intention after new education interventions, with low-enjoyment athletes showing greater gains in reporting intention.
