Background: Most epidemiological studies on track-and-field meets have been limited to the Olympics and world championships. These are meets in which only high-performance athletes participate at a certain time of the year. In contrast, epidemiological studies on athletes of various ages and across different seasons may provide health care providers with valuable insights into injury prevention and on-field medical care. The study aims to determine the trends and locations of injuries during track-and-field meets in athletes of various ages and seasons based on on-field medical care records. Methods: The number and incidence of injuries requiring on-field medical care during or after the event were obtained from 39 track-and-field meets. Injuries were defined as cases that required on-field medical care. The incidence was defined as the number of injuries per 1000 athlete exposures wherein 1 athlete exposure is the athlete’s participation in one event. We also recorded the number of injuries at each location and whether transportation to a medical station was required. Results: A total of 191 injuries were reported. This study identified a population with a high incidence of injury (middle- and long-distance events, combined events, and athletes over the age of 19), areas within the stadium where injuries were more likely to occur (finish line and first turn), and a high rate of transport to the medical station (approximately 70%); most of them were transported to wheelchairs. Conclusion: The results provide insights into the trends, locations, and transport of injured athletes during track-and-field meets. Professionals will better understand the injuries occurring during track-and-field meets and can improve the efficiency of on-field medical care activities. They will also assist organizers in track-and-field meets to improve the safety of their meet operations.

Context: The aim of this study was to investigate the acute effects of Swedish massage and manual lymph drainage (MLD) on performance parameters related to jumping, walking, and blood lactic acid levels after Nordic hamstring exercises. Design: This study was designed as a controlled crossover study. Methods: The study included 16 young trained men. Participants’ lactic acid levels, gait-related parameters, and jumping performance were assessed. Assessments were performed at baseline, after Nordic hamstring exercises, and after 3 different passive recovery strategies: resting, Swedish massage, and MLD for 3 weeks. Results: As a result of the study, it was observed that lactic acid levels after the MLD and massage intervention were significantly lower in both MLD and massage conditions compared with the control condition (P < .05). There was no within- and between-conditions difference in jumping parameters after the MLD and massage interventions (P > .05). Walking speed in the MLD condition was statistically higher following the intervention compared with both before and after exercise (P < .05). Step time in the massage condition was statistically lower after the intervention compared with after Nordic hamstring exercise (P < .05). Conclusions: Although MLD and massage interventions have positive effects on lactic acid levels and walking and jumping parameters, they are not superior to each other. MLD can be used as a passive recovery technique after exercise.

National Collegiate Athletic Association (NCAA) student athletes may have more stigmatic views toward mental health (MH) and be less open to talking about or seeking support for MH struggles than their peers. This may contribute to and/or exacerbate existing MH challenges. This cross-sectional study explored the impact of MH stigma, support, and openness on student athletes’ levels of depression, anxiety, and stress among 478 NCAA student athletes representing 20 different sports from 56 universities. Results indicated that male, Black, Indigenous, People of Color (BIPOC), and Division I athletes reported higher levels of MH stigma. Compared with their White peers, BIPOC athletes exhibited less openness to talk about MH challenges. Division I and BIPOC athletes felt less supported to seek help for MH concerns. Structural equation modeling showed that MH stigma was positively associated with depression, anxiety, and stress, whereas MH openness was negatively associated with depression, anxiety, and stress. Research/practical implications, limitations, and future research and athletic department programming needs are discussed.

Context: Evidence indicates a 2 to 3 times increased risk of musculoskeletal injury after return to play from concussion. Undetected neuromuscular control deficits at return to play may relate to increased musculoskeletal injury risk. Rehabilitation to improve neuromuscular control may benefit patients with concussion, but access to rehabilitation professionals and/or poor adherence may limit efficacy. Our purpose was to determine the feasibility of an 8-week virtual neuromuscular training (NMT) program administered through a novel smartphone application among physically active, uninjured adults. Design: Feasibility trial. Methods: Participants were instructed to complete an NMT program administered via a smartphone application and returned for follow-up questionnaires 8 weeks later. They were instructed to complete 3 asynchronous self-guided workouts per week during the 8-week intervention period. Workouts included balance, plyometrics, strengthening, and dual-task exercises. The application provided instructions for each exercise using video, text, and audio descriptions. Our primary feasibility measure was participant adherence, calculated as the percentage of workouts completed out of the total possible 24 workouts. We recorded the average duration of each workout using start/stop/advance features within the application. Results: Twenty participants were enrolled, of which 15 (age = 26.3 [2.7] y, 67% female) returned for follow-up (75% retention). Participant adherence was 57.2% (25.0%; range: 16.7%–91.7%). Participants spent 17.3 (8.0) minutes per workout (range: 7.4–37.9 min). There were no adverse reactions or injuries. Most participants (60%) reported time availability as a primary barrier to intervention completion. Conclusions: Participants were moderately (>50%) adherent to a virtual NMT program, without any reported injuries. We identified several barriers to participation and pathways for improved adherence in the future. The virtual NMT program completed by uninjured adults provides evidence of its feasibility and future scalability to those with a recent concussion to address neuromuscular control deficits and reduce future injury risk.

Context: The sequelae of concussion may have psychological consequences that affect an athlete’s ability to return to play (RTP). However, confidence of RTP readiness is rarely monitored after a concussion. Design: This study examined the acute and longitudinal implications of concussion on an athlete’s confidence to RTP, the relationship between self-reported symptoms and athlete confidence to RTP, and interactions between concussion symptoms, sex, sport type (contact vs noncontact), and confidence to RTP. Methods: Forty-six college athletes (65% female) sustained a concussion and completed the Injury Psychological Readiness to Return to Sport (I-PRRS) scale at 3 timepoints: within 72 hours of injury (acute), within 72 hours of beginning the RTP protocol (pre-RTP), and within 72 hours of being fully cleared to RTP (post-RTP). Results: Athletes reported acute low confidence after concussion (I-PRRS mean [SD] = 32.59 [18.45]), which improved over time (pre-RTP mean [SD] = 52.11 [9.60]; post-RTP mean [SD] = 57.45 [5.96]). Some athletes returned to competition (post-RTP) with lingering confidence concerns (ie, I-PRRS < 50; 95% CI = 0.03–0.26). Acute symptom severity was associated with worse confidence (P < .001). Sex and sport type (contact vs noncontact) had no relationship with confidence (P = .406, P = .3314, respectively). These results indicate that athletes lack confidence acutely (within 72 h) following concussion. Conclusions: Although confidence improves over time, those who report greater acute symptoms also exhibit decreased confidence, and some athletes are returning to play with lingering concerns about their confidence (I-PRRS < 50). This preliminary evidence of heterogeneous confidence following concussion encourages the assessment and monitoring of confidence throughout concussion rehabilitation.

Most injuries that dancers sustain are to the lower extremities, specifically the foot and ankle region. Numerous potential risk factors have been examined for dancer injuries such as technical mistakes and fatigue. The purpose of this study was to compare landing kinematics and kinetics during jumps that are common in dance pre and postfatigue. Ten adolescent advanced level dancers participated in this study. Subjects completed 3 split leaps and 3 center leaps before and after a fatigue protocol performed on a stationary bike. Live motion capture was used to record landing kinematic and kinetic data. Results of this study showed a significant increase in ankle eversion and external rotation angles for center leaps from pre- to postfatigue protocol (P = .020 and P = .020, respectively) as well as significant increases in ankle eversion and knee adduction moments for center leaps (P = .020 and P = .036, respectively). These results show that after a fatigue protocol, there are changes to the kinematics of dancers that may make them more susceptible to ankle injury.
