Make It or Break It? Injury Impacts More Than Half of Deselected Athletes Who Dropped Out of the High-Performance Pathway System. A 4-Year Retrospective Cohort Study.

To investigate: (1) the injury epidemiology in an Australian academy; (2) how athletes transition through the high-performance sport (HPS) pathway; and (3) why athletes leave this HPS program. This retrospective cohort study was conducted at an Australian HPS academy over a 4-year period. Medical attention injuries were prospectively recorded. Injury incidence rates (IIR) and burden were calculated per 365 athlete-days, according to sport, sex, and pathway level. Athlete pathway levels were mapped to the Foundations, Talent, Elite, and Mastery (FTEM) framework. Reasons for athletes transitioning out were reported. Four hundred and eighty-one injuries were reported across 124 athletes at an IIR of 2.09 injuries per 365 athlete-days (95% CI = 1.91-2.29). Most athletes (103, 83.1%) were injured at least once over the 4-year period. IIRs increased (IRR = 1.17, 95% CI = 1.06-1.29, p = 0.001) as athletes progressed through the pathway. The most common reason for athlete attrition was deselection due to performance (n = 18), with 55.6% of these athletes sustaining an injury in the season prior to deselection. Injury burden was highest at E2 (119.5 days absence per 365 athlete-days (95% CI = 62.18-229.67)) and lowest at T4 (30.47 days absence per 365 athlete-days (95% CI = 21.98-42.24)). Injury occurrence is common across HPS, with IIRs increasing as athletes progressed to higher talent levels. Deselection due to poor performance was the main attrition factor, with more than half the deselected athletes impacted by injury prior to deselection. This study highlights an increased risk of deselection, following injury, and indicates the need for further development of prevention strategies targeting pathway athletes.

The prevalence and factors associated with knee pain in a sample of cyclists within the United Kingdom: A cross sectional study

The study aimed to determine: (i) the lifetime and period prevalence of knee pain, (ii) the prevalence and nature of medical attention cycling- related injuries, (iii) and the risk factors associated with knee pain and in a sample of competitive and non-competitive cyclists in the UK. A cross-sectional questionnaire was used to collect data on knee pain, medical attention injuries, and potential risk factors associated with knee pain. Participants were competitive and non-competitive cyclists aged 18 years and older and were recruited through cycling clubs and online advertisement. Binary logistic regression was used to assess for potential risk factors associated with knee pain. Crude and adjusted odds ratios were reported in staged adjustment models, controlling for potential confounders of age and sex. Keele University Ethics Committee approved this study. A total of 115 respondents completed the questionnaire. Lifetime knee pain prevalence was 48%, with period prevalence 26.1% (past-month) and 18.3% (past-week). Aged 40 and over was the only factor found to be associated with knee pain, although this was no longer significant after adjustment for sex. The most prevalent site and type of injury was the lower back and fracture (traumatic), respectively. Knee pain prevalence is high in this sample of cyclists, particularly in those aged 40 years and over. Injury prevention strategies should target the lower back and fractures. Longitudinal research is needed to identify if there are modifiable risk factors that may reduce the occurrence of both knee pain and traumatic fractures in cyclists.

Benefits of sleep on reduction of injury and illness in Division I female soccer players

Injuries in soccer athletes continues to rise and there is a cause for concern. Collegiate athletes have physically demanding workloads and struggle to sleep an adequate amount each night. A potential association is how sleep could play a role in an athletes’ injury. 24 NCAA DI women’s soccer athletes were utilized during the Fall 2019 season. Athletes self-reported their daily hours slept and the athletic trainer tracked and classified athletes’ injury and illness status: no-injury, medical attention injury, or time loss injury. K-mean clustering was utilized to classify the athletes into 3 groups: injury/illness-free group (n=12), mild-to-moderate injury/illness group (n=7), and heavy injury/illness group (n=5). Sleep was statistically significantly lower in the heavy-injury group than other groups and small effect sizes were detected (d31 = .282, p < .001; d32 = .278, p < .001). Based on the data, it appears hours slept plays a factor in female soccer athletes’ risk of injury.

One-Year Injury History and Safe Dance Practices Among Female Highland Dancers in Canada.

Over 8,650 Highland dancers registered to compete in Royal Scottish Official Board of Highland Dancing events worldwide in 2019. While the burden of dance-related injuries is high among dancers, there are few studies examining Highland dance. The purpose of this study was to describe the prevalence of self-reported 1-year injury history and safe dance practices among female Highland dancers. Sixty-five female Canadian Highland dancers (median age 18; range 14-47) completed an anonymous online survey at the beginning of the 2019 championship season. Demographics (i.e., age, body mass index), exposure (e.g., months/year dancing), safe dance practices (e.g., environmental, physical, psychological), and 1-year injury history (i.e., yes/no) were self-reported. Three definitions of dance-related injury were used: 1) time-loss (missed ≥1 class, practice, performance, and/or competition); 2) medical attention (requiring professional medical care); and 3) any physical complaint that affected full participation. Most participants were training at the elite standard/premier level (86%, 95%CI 75-93) and for ≥8 months/year (83%, 95%CI 75-93). The proportion of dancers reporting at least one physical complaint in the previous 1 year was 71% (95%CI 58-81). Sixty percent (95%CI 47-71) of dancers reported ≥1 medical attention and/or time-loss injury. All participants reported warming up regularly, with 59% (95%CI 46-70) participating in regular cool-downs. The prevalence of 1-year injury history among female Highland dancers is high. Education on the benefits of safe dance practice for Highland dancers may be useful. Prospective cohort studies are needed to understand the dynamic nature of dance injuries across a full competitive season.

What do we know about beach soccer injuries? Systematic video analysis of four consecutive years with 580 match injuries

ABSTRACT The aim of the present study was to evaluate the characteristics of match injury in male beach soccer players. Video recordings of all official beach soccer tournaments in which the European national male beach soccer teams participated from 2018 to 2021 were analysed by two sports medicine specialists retrospectively. Regarding each injury, data including the mechanism, location of the injury, whether the injury led to time-loss, and the relationship of the injury to the bicycle kick (BK), etc. were documented. A total of 632 injuries were documented, corresponding to 234.9 injuries/1000 player hours. Video footage was available for 580 injuries. Whilst 79.8% of medical attention injuries occurred due to opponent contact, 19.5% of time-loss injuries occurred due to non-contact, and 12.2% of indirect opponent contact (p < 0.01). The most common location of the BK related injury was the head/neck (68.7%), whereas most common location of the BK unrelated injury was the lower extremity (54.1%) (p < 0.01). The findings demonstrated that beach soccer injury incidence was quite high; the most common injury location was head/neck and head/neck injuries were associated with BK. In light of these results, some rule regulations, particularly those associated with BK, and the use of protective equipment should be considered to prevent these injuries.

Epidemiology of musculoskeletal injury in military recruits: a systematic review and meta-analysis

BackgroundInjuries are a common occurrence in military recruit training, however due to differences in the capture of training exposure, injury incidence rates are rarely reported. Our aim was to determine the musculoskeletal injury epidemiology of military recruits, including a standardised injury incidence rate.MethodsEpidemiological systematic review following the PRISMA 2020 guidelines. Five online databases were searched from database inception to 5th May 2021. Prospective and retrospective studies that reported data on musculoskeletal injuries sustained by military recruits after the year 2000 were included. We reported on the frequency, prevalence and injury incidence rate. Incidence rate per 1000 training days (Exact 95% CI) was calculated using meta-analysis to allow comparisons between studies. Observed heterogeneity (e.g., training duration) precluded pooling of results across countries. The Joanna Briggs Institute Quality Assessment Checklist for Prevalence Studies assessed study quality.ResultsThis review identified 41 studies comprising 451,782 recruits. Most studies (n = 26; 63%) reported the number of injured recruits, and the majority of studies (n = 27; 66%) reported the number of injuries to recruits. The prevalence of recruits with medical attention injuries or time-loss injuries was 22.8% and 31.4%, respectively. Meta-analysis revealed the injury incidence rate for recruits with a medical attention injury may be as high as 19.52 injuries per 1000 training days; and time-loss injury may be as high as 3.97 injuries per 1000 training days. Longer recruit training programs were associated with a reduced injury incidence rate (p = 0.003). The overall certainty of the evidence was low per a modified GRADE approach.ConclusionThis systematic review with meta-analysis highlights a high musculoskeletal injury prevalence and injury incidence rate within military recruits undergoing basic training with minimal improvement observed over the past 20 years. Longer training program, which may decrease the degree of overload experienced by recruit, may reduce injury incidence rates. Unfortunately, reporting standards and reporting consistency remain a barrier to generalisability.Trial registrationPROSPERO (Registration number: CRD42021251080).

Musculoskeletal injury in an Australian professional ballet company, 2018-2021: 953 medical-attention and 706 time-loss injuries over 4 years.

OBJECTIVES: To describe the incidence rate, frequency, severity, recurrence, and burden of musculoskeletal injury in professional ballet. STUDY DESIGN: Descriptive epidemiological (retrospective). METHODS: Professional dancers (n=73, 40 females, 33 males) provided consent for retrospective review of musculoskeletal injury data. Medical-attention injuries were reported to and recorded by onsite physiotherapists between January 2018-December 2021. Time-loss injuries were any injury that prevented a dancer from taking a full part in all dance-related activities for >1 day. Injuries were classified using the OSICS-10.1 system. Injury incidence rates (IIR; injuries/1000hours), severity, recurrence, and burden were calculated. RESULTS: Nine hundred and fifty-three medical-attention injuries were recorded in 72 (98%) dancers at an IIR of 2.79/1000hrs (95%CI 2.62-2.98). 706 were time-loss injuries, which were reported in 70 dancers at an IIR of 2.07/1000hrs (95%CI 1.92-2.23). Overuse injuries represented 53% of medical-attention injuries. The most frequently injured body area and tissue/pathology were thoracic facet joint (n=63/953, 7%) and ankle synovitis/impingement (n=62/953, 6%). Bone stress injuries (BSI) were the most severe with the highest median time-loss (135 days, IQR 181), followed by fractures (72.5 days, IQR 132). The injuries with the highest burden were tibial BSI (13 days lost/1000 hours, 95%CI 13-14). Jumping and lifting were most frequently reported injury mechanisms. CONCLUSIONS: Almost all dancers required medical-attention for at least one injury during the surveillance period. Approximately 74% of injuries resulted in time-loss. BSI and ankle synovitis/impingement were of high burden and a high proportion of BSI were recurrent.

Introduction: Several international sports federations have implemented a standardized injury registration system during their championships. However, very few studies have included athletes with disabilities during major competitions, apart from the Paralympic Games. Therefore, the objective of this study is to evaluate the rate and characteristics of illnesses and injuries during the 2021 South America Wheelchair Basketball Championships. Material and method: The coaching staff of the 11 participating teams (a total of 129 players) were asked to report daily all the health problems that have occurred and their characteristics in a standardized form. Prevalence and incidence rates were calculated. Results: In this study 108 health problems were reported, equivalent to 83.7 per 100 players [95% CI: 67.9-99.5], with 8 timeloss health problems (6.2 per 100 players [95% CI: 1.9-10.5]) and a total of 74 medical attention injuries (57.4 per 100 players [95% CI:44.3-70.4]). Were reported 15 diseases, and the most affected organ systems were ophthalmologic, gastrointestinal, and genitourinary. More injuries were recorded during matches (n=43). The most affected regions were shoulder/clavicle (24.7%), hand/fingers (23.7%) and neck/cervical spine (12.9%). The most frequent conditions were muscle contractures/cramps (32.2%), and the predominant mechanism was overuse (53.8%). 2.2% of concussions produced during training were reported. Most of the recorded events were without time loss and with return to full participation between zero and one day. Conclusion: Monitoring of health problems during competitions is essential to determine sport-specific injury risk factors, and a complex approach should be implemented for the recognition of their characteristics in wheelchair basketball players. In this way, adequate preventive measures can be developed.

Epidemiological Characteristics of Foot and Ankle Injuries in 2 Professional Ballet Companies: A 3-Season Cohort Study of 588 Medical Attention Injuries and 255 Time-Loss Injuries.

The foot and ankle are often reported as the most common sites of injury in professional ballet dancers; however, epidemiological research focusing on foot and ankle injuries in isolation and investigating specific diagnoses is limited. To investigate the incidence rate, severity, burden, and mechanisms of foot and ankle injuries that (1) required visiting a medical team (medical attention foot and ankle injuries; MA-FAIs) and (2) prevented a dancer from fully participating in all dance-related activities for at least 24 hours after the injury (time-loss foot and ankle injuries; TL-FAIs) in 2 professional ballet companies. Descriptive epidemiological study. Foot and ankle injury data across 3 seasons (2016-2017 to 2018-2019) were extracted from the medical databases of 2 professional ballet companies. Injury-incidence rate (per dancer-season), severity, and burden were calculated and reported with reference to the mechanism of injury. A total of 588 MA-FAIs and 255 TL-FAIs were observed across 455 dancer-seasons. The incidence rates of MA-FAIs and TL-FAIs were significantly higher in women (1.20 MA-FAIs and 0.55 TL-FAIs per dancer-season) than in men (0.83 MA-FAIs and 0.35 TL-FAIs per dancer-season) (MA-FAIs, P = .002; TL-FAIs, P = .008). The highest incidence rates for any specific injury pathology were ankle impingement syndrome and synovitis for MA-FAIs (women 0.27 and men 0.25 MA-FAIs per dancer-season) and ankle sprain for TL-FAIs (women 0.15 and men 0.08 TL-FAIs per dancer-season). Pointe work and jumping actions in women and jumping actions in men were the most common mechanisms of injury. The primary mechanism of injury of ankle sprains was jumping activities, but the primary mechanisms of ankle synovitis and impingement in women were related to dancing en pointe. The results of this study highlight the importance of further investigation of injury prevention strategies targeting pointe work and jumping actions in ballet dancers. Further research for injury prevention and rehabilitation strategies targeting posterior ankle impingement syndromes and ankle sprains are warranted.

Contact injuries in field hockey and the potential role for personal protective equipment

ABSTRACT Field hockey is played with sticks and a hard ball. It is fast-paced, with athletes playing together in close proximity. Athletes may be at increased risk of sustaining injuries through contact. The aim of this study was to investigate the epidemiological characteristics of contact injuries in field hockey. Data were collected during the 2017/2018 and 2018/2019 Irish Hockey League seasons. This study included two methods of data collection among male athletes: self-reported injuries and via those reported by the teams’ physiotherapists. Injuries were defined as any physical complaint sustained during field hockey, supplemented by medical attention and time-loss injuries. Only contact injuries were included for analysis. Overall, 107 contact injuries were incurred, giving rise to an injury incidence rate of 3.1/1000 h, and accounting for 33.1% of all injuries. Athletes had an absolute risk of 0.372 of sustaining a contact injury. Contusions (48.6%) were the most common type of contact injury, while injuries to the head/face (20.6%) were the most frequently reported location. Contact injuries represent an important proportion of all injuries. Rule changes to mandate the use of personal protective equipment in field hockey may assist in reducing the absolute risk and severity of contact injuries in field hockey.

Comparison of injury profiles between elite Australian male and female cricket players.

This study presents seven seasons of injury surveillance data for both elite Australian male and female cricket players, revealing injury statistics and allowing for comparison between sexes. Retrospective cohort. Participants were elite Australian male and female cricket players who were contracted to play for a national and/or state/territory team and/or T20 franchise between 2015-16 and 2021-22 (7 seasons). Injury data was recorded in Cricket Australia's Athlete Management System database and combined with match data. The STROBE-SIIS statement was used as the relevant guideline for this study. Data for 1345 male player seasons and 959 female player seasons revealed sex-related differences in the injury incidence rates and prevalence. Males had higher incidence (average 136 vs 101 injuries per 1000 match days) and prevalence of match time-loss injuries (average 10.4% vs 6.5% players unavailable). However, the overall incidence of all medical attention injuries were similar between sexes (Incidence Rate Ratio (IRR) 0.9, 95%CI 0.8-1.0). The most frequent match time-loss injuries for males were hamstring strains (7.4 new injuries per 100 players per season), side and abdominal strains (5.5), concussion (5.0), lumbar stress fractures (4.3), and wrist and hand fractures (3.9). The most frequent match time-loss injuries for females over the 7 seasons were hamstring strains (3.1), concussion (2.3), quadriceps strains (2.4) and shin/foot/ankle stress fractures (2.0). The IRR of medical attention injuries for males compared to females was higher for lumbosacral stress fractures (IRR 2.3), elbow and forearm injuries (1.5), and concussion (1.4), and lower for lower leg, foot, and ankle stress fractures (0.6), shoulder and upper arm injuries (0.7), and quadriceps strains (0.6). Robust long-term injury surveillance enabled the injury profiles of elite Australian male and female cricket players to be understood and compared. Males had a higher incidence and prevalence of match time-loss injuries, likely reflecting a higher match exposure.

Injuries in Youth Volleyball Players at a National Championship: Incidence, Risk Factors, and Mechanisms of Injury.

To evaluate injury incidence rates, types, mechanisms, and potential risk factors in youth volleyball. Prospective cohort. 2018 Canadian Youth National Volleyball Tournament. Thousand eight hundred seventy-six players [466 males, 1391 females, mean age 16.2 years (±1.26)] consented to participate (19.5%). Sex (male/female), age group, position, and underage players. Players completed a questionnaire (demographic information, injury, and concussion history). Medical attention injuries were recorded by tournament medical personnel through an injury report form (eg, mechanism and type). Injury was defined as any physical complaint seeking onsite medical attention. Concussion was defined using the fifth International Consensus. Injury rates adjusted for cluster by team were calculated by sex. Exploratory multivariable Poisson regression was used to analyze potential risk factors (eg, sex, age group, position, and underage players) for injury, adjusted for cluster by team and offset by athlete exposures (AEs). There were 101 injuries in the 7-day tournament {IRFemale = 6.78 injuries/1000 AEs [95% confidence interval (CI), 5.27-8.72]; IRMale = 4.30 injuries/1000 AEs (95% CI, 2.55-7.24)}. Joint sprain (n = 29, 28.71%) and concussion (n = 26, 25.74%) were the most common. Most concussions were associated with ball-to-head contact (61.5%). There was no statistically significant difference in injury rate by sex (IRRF/M: 1.47; 95% CI, 0.80-2.69). The rates of injury in U14 were higher than U18 (IRRU14: 2.57; 95% CI, 1.11-5.98). Injury rates are high in youth volleyball tournament play, with the highest rates in U14. More research is needed to inform the development of volleyball-specific injury prevention strategies.

Establishing the incidence and prevalence of injury and illness in Australian sailing athletes over a full year of training and competition to help determine prevention priorities

ObjectivesTo investigate the prevalence, incidence rate (IR) and burden of health problems (injuries and illnesses) in Australian Olympic class and State Sailing Pathway Program (SSPP) athletes over 12-months of training and competition. DesignDescriptive epidemiological study. MethodsNinety-two Australian Sailing and SSPP athletes were prospectively followed during the 2019–2020 season. Medical attention injuries and illnesses were prospectively recorded, and further sub-categorised according to time loss. The IR and burden were calculated per 365 athlete-days, with differences in IR between sexes compared using negative binomial generated rate ratios. ResultsThree hundred and forty-nine injuries were reported in 53 athletes (57.6 %), with 14.3 % resulting in time loss. Injury IR was 3.71 (95%CI = 3.33–4.12) injuries per 365 athlete–days, with no difference observed between sex (IRR = 1.64; 95%CI = 0.81–3.34). Shoulder injuries were found to have the greatest burden. Fifty-four illnesses were reported in 27 athletes (29.3 %), with 39.0 % resulting in time loss. Respiratory infection (n = 22, 40.7 %) was the most common illness reported. Illness IR was 0.57 (95%CI = 0.43–0.75) illnesses per 365 athlete days, with females found to have a 3.6 fold increase in illness compared to males (IRR = 3.6; 95%CI = 2.0–6.7). ConclusionsThe majority of health problems reported in sailing athletes did not result in time loss. There were no differences in the injury IR between sexes, however females had a 3.6-fold increase in reported illness. These results can inform future strategies to reduce key health problems in sailors. Future research investigating whether performance is impacted by the high rate of non-time loss health problems is warranted.

Weekly injury rates within semesters of a three-year tertiary dance program, and prospective training monitoring across one semester of training: a longitudinal study

ABSTRACT Dance research should consider time points within a season that may be associated with injury, and report on weekly dance training loads. The current study aimed to analyse injuries within each semester and participant, monitor load, mood and stress within one semester, and calculate compliance with monitoring in a tertiary dance training cohort. The dance training program that participants are drawn from is a six-semester, three-year undergraduate course, training in ballet and contemporary dance. A better understanding of injury in dance may further refine load management and injury prevention strategies. Fourteen tertiary dance students consented to participate. A medical attention injury definition was used. Weekly injury rate ratios within each 14-week semester were calculated. Participants completed ratings of perceived exertion , and mood and stress questionnaires across one semester. Injuries were significantly increased for Week 5, Semester 1; Week 2, Semester 2; and Week 1, Semester 3, and 4. Spikes in load coincided with injury spikes, as observed visually on a line graph. Certain weeks in proximity to a change in training schedule had increased injury. Applying training principles in response to monitoring, specifically to return to dance after a holiday period, may aid in reducing injuries at this time requiring further investigation.

Observed Injury Rates Did Not Follow Theoretically Predicted Injury Risk Patterns in Professional Human Circus Artists.

Identifying which types of athletes have increased injury risk (ie, predictive risk factors) should help develop cost-effective selective injury prevention strategies. Our objective was to compare a theoretical injury risk classification system developed by coaches and rehabilitation therapists, with observed injury rates in human circus acts across dimensions of physical stressors, acrobatic complexity, qualifications, and residual risks. Descriptive epidemiological study. professional circus company. Human circus artists performing in routine roles between 2007 and 2017. Characteristics of circus acts categorized according to 4 different dimensions. Medical attention injury rates (injury requiring a visit to the therapist), time-loss injury rates (TL-1; injury resulting in at least one missed performance), and time-loss 15 injury rates (TL-15; injury resulting in at least 15 missed performances). Among 962 artists with 1 373 572 performances, 89.4% (860/962) incurred at least one medical attention injury, 74.2% (714/962) incurred at least one TL-1 injury, and 50.8% (489/962) incurred at least one TL-15 injury. There were important inconsistencies between theoretical and observed injury risk patterns in each of the 4 dimensions for all injury definitions (medical attention, TL-1, and TL-15). Although theoretical classifications are the only option when no data are available, observed risk patterns based on injury surveillance programs can help identify artists who have a high (or low) theoretical risk but are nonetheless actually at low (or high) risk of injury, given their current roles. This will help develop more cost-effective selective injury prevention programs.

Relationships Between Performance and Injury Occurrence in Athletics (Track and Field): A Pilot Study on 8 National-Level Athletes From Sprints, Jumps and Combined Events Followed During at Least Five Consecutive Seasons.

BackgroundPerformance success or failure in athletics (Track and Field) and the capacity to succeed are driven at the adult level, like in other sports, by many factors, injury being one of them. More information regarding the potential relationships between performance and injuries in athletics is needed.ObjectiveTo analyse the potential association between performance and occurrence of injuries in national-level athletics athletes from sprints, jumps and combined events through several seasons.MethodsWe performed a retrospective analysis of performance and injury data collected prospectively in 8 national-level athletics athletes followed during at least five consecutive seasons from 2009 to 2019. For each athlete, injuries data [total injuries (injuries) and time-loss injuries (TLI)] were collected by the same sports medicine physician throughout the study period using a medical attention injury definition. Performances during official competitions were collected on the French Federation of Athletics website, and included (i) any participation in national championships, (ii) any participation in an international competition (i.e., being national team member for an international competition), (iii) any podium at the national championships, (iv) any podium at an international competition, and (v) performance metrics normalised to the world record (WR) of the respective athletics speciality (%WR). For each athlete, we performed a descriptive analysis of the performances and injuries. We also performed four binomial logistic regressions with (1) national championships participation (yes/no) or (2) international competition participation (yes/no) as dependent variables, and injuries (yes/no) or TLI (yes/no) as independent variables, adjusted for individual athlete and number of seasons, and in models on participation in international competitions, was also adjusted for national championship participation (yes/no), with Odd Ratios (OR) with 95% confidence intervals (95%CI).ResultsAmong the 8 national-level athletics athletes included in the present study, cumulated 155 injuries, including 52 TLI (33.5%). There was an average of 2.7 ± 1.7 injuries and 0.9 ± 0.6 TLI per athlete per season over the study period. The occurrence of injuries was significantly associated with higher odds of national championships participation (OR = 4.85 [95% CI 3.10 to 3050.5], p = 0.021). The occurrence of TLI was significantly associated with higher odds of national championships participation (OR = 133.6 [95% CI 4.92 to 14251.5], p = 0.013). The occurrence of injuries or TLI were associated with insignificantly lower odds of international championships participation.ConclusionsOur present pilot study confirms that injuries are part of an athletes' life. The occurrence of at least one injury was associated with higher odds of participation in a national championship, whereas the absence of at least one injury was associated with higher odds of participation in an international championship. We hypothesised that the length of the season can play a role in the risk of injury occurrence, but if the athlete wants to reach his/her highest level, decreasing the risk of injuries seems to be of importance. Despite the caution that should be taken in the interpretation of our results, our present study confirms the interest and relevance of injury risk reduction approach in athletics.

Epidemiology of injuries sustained in professional Australian netball: A three season cohort study

ObjectivesTo report the medical attention and time-loss injury epidemiology of Australia's premier netball competition. DesignDescriptive epidemiological study. MethodsOne-hundred and nineteen players in the Suncorp Super Netball league were under surveillance during three consecutive seasons (2017–2019), inclusive of pre-, in-, and post- season phases. Medical attention injuries were recorded by medical personnel, and additionally sub-categorised according to time loss. Injury incidence rates (IIR) and injury burden were calculated per 365 player contract days, with differences between season and season phase IIRs compared using negative binomial generated incidence rate ratios (IRR). ResultsEight hundred and sixty-six medical attention injuries and 393 time-loss injuries were recorded. The majority of the players had multiple (≥2) medical attention (n = 92; 77.3%) and time-loss (n = 75, 63.0%) injuries reported. The ankle (n = 181; 20.9%), knee (n = 136; 15.7%) and foot (n = 98; 11.3%) were the body sites with the most frequently reported medical attention injuries. Overall, there was a comparable injury incidence rate between the pre-season and in-season periods (IRR = 1.13, 95%CI = 0.98–1.30, p = 0.0842), although variation in the injury burden was identified. Ankle tendon injuries (23.5 days absence) and knee joint injuries (44.9 days absence) the most burdensome injuries in the pre-season and in-season periods respectively. ConclusionsLower limb injuries are the most frequent in professional level netball. Knee and ankle injuries are the most burdensome overall, however the type of injuries with a high burden vary between pre- and in-season periods. Time-loss, non-time loss and subsequent injuries are prominent in professional level netball.

Injury incidence and burden during senior inter-provincial field hockey tournaments.

Field hockey is an Olympic sport played internationally and in which South Africa is a participating nation. It also has its own world cup. Few injury studies have been published on South African field hockey. Research efforts should increase within the sport to ensure safe participation and mitigate the inherent injury risks. The objective of the study was to attend the male and female inter-provincial field hockey tournaments in South Africa and determine the incidence of injury and burden of acquired sport injuries (time-loss and medical attention). A quantitative, descriptive, longitudinal study, including 133 females and 139 males, was conducted. Participants completed baseline questionnaires prior to the tournament and post-match questionnaires detailing injuries during the tournament. The recorded injuries were 77.9 (females) and 99.5 (males) per 1 000 player match hours. Medical attention was 51.9 (females) and 70.3 (males) injuries per 1 000 player match hours. The result for time-loss injuries was 4.3 (females) and 7.5 (males) injuries per 1 000 player match hours. The study found high incidence rates of all injuries and medical attention injuries; however, the incidence of time-loss injuries was low in comparison to existing literature. Comparing current results to existing literature is challenging due to the heterogeneity of methodologies and injury definitions in field hockey research. This was the largest observational study in field hockey conducted in South Africa. The international sporting body should establish a consensus for future research and the South African Hockey Association explore long-term surveillance in South Africa to mimic similar national codes.

Despite a high daily training availability, a quarter of Academy athletes start the season with an injury and three quarters finish with one

Introduction: The development (or academy) phase of an athlete forms the foundation for a successful athletic career. Injuries affect an athlete’s availability to train, compete, and perform. Context-specific understanding of the injury burden and risk factors can enable prevention strategies to be prioritised, developed, and implemented to positively impact academy athlete longevity and trajectory towards elite levels. Medical servicing is a key component of the health system around an athletic population. Currently there are no data pertaining to the delivery of medical services in Australian academy athletes. We aim to investigate the incidence, prevalence, burden and characteristics of injuries; and to describe the frequency and type of medical servicing for elite sports academy athletes over a 12-month season. Methods: Medical attention and time-loss injuries were prospectively recorded for 94 athletes (72.3% females) during the 2019-2020 scholarship season. The number and type of linked medical treatments was also recorded. Injury incidence rates (IIR), point and period prevalence, and injury burden were calculated and compared by athlete sex, sport, and categorisation using incidence rate ratios (IRR). Results: 193 injuries were reported in 71 (75.5%) athletes. The IIR was 2.08 (95%CI=1.80-2.40) injuries per 365 days, with no sex difference observed (IRR=1.05, 95%CI=0.77-1.43, p=0.761). The injury burden was 43.52 (95%CI=37.79-50.11) days absence per 365 days. More than one-quarter (point prevalence, 26.6%) of athletes commenced the season with an injury. In-season injury risk was 2.5 times higher in athletes commencing the season with an injury (IRR=2.49, 95%CI=1.85-3.35, p<0.0001). 75.5% of athletes sustained a medical-attention injury within the 12 month period, medical servicing was not uniform across sports, and despite this, a mean daily athlete availability rate of 87% was observed which fluctuated significantly across the period between 79% and 92%. 81.2% of the 1164 treatments recorded were physiotherapy, with an overall 4.3:1.0 physiotherapy to medicine treatment ratio. Discussion: This is the first study to report the incidence, prevalence, burden, and characteristics of injuries, and the frequency and type of medical servicing delivered to athletes across multiple sports at a State Academy of Sport in Australia. One in four athletes began the elite pathway season with a pre-existing injury, while also demonstrating a 2.5 increased risk of subsequent injury in the scholarship period. Injury profiles and medical servicing varied across sports highlighting the need for service delivery models, prevention programs, and scholarship selection processes to be flexible and supportive of athlete health requirements.

A Cross-Sectional Study of Retired Great British Olympians (Berlin 1936\u2013Sochi 2014): Olympic Career Injuries, Joint Health in Later Life, and Reasons for Retirement from Olympic Sport

BackgroundThe relationship between Olympic career sport injury and the long-term musculoskeletal health of the elite athlete remains unclear. This study describes the lifetime prevalence of medical attention injuries that occurred during training and/or competition as part of the athlete’s Olympic career, reasons for retirement from Olympic sport, and the point prevalence of pain and osteoarthritis (OA) among retired Great Britain’s (GB) Olympians.MethodsThis cross-sectional study involved distributing a questionnaire to retired GB Olympians who had competed at 36 Olympic Games between Berlin 1936 and Sochi 2014. The questionnaire captured Olympic career injury history (lasting ≥ 1 month), sport exposure, musculoskeletal pain (last 4 weeks), physician-diagnosed OA, and joint replacement. Injury prevalence was calculated for sports with a minimal of 15 respondents. Adjusted odds ratios (aOR) were estimated in logistic regression for pain, OA, and joint replacement. Models were adjusted for age, sex, BMI, and career duration.ResultsSix hundred fifty (57.8% male; 42.2% female) retired athletes representing 40 sports (29 summer; 11 winter), aged 60.5 years (range 23–97), completed the questionnaire. Overall, 721 injuries (368 athletes) were self-reported equating to a lifetime Olympic career injury prevalence of 56.6%. Injury prevalence was highest in field athletics (81.0%), gymnastics (75.0%), and track athletics (67.7%). Injuries most frequently occurred at the knee (19.0%), lower back (15.4%), and shoulder (11.5%). Of those injured, 19.5% retired from sport due to injury. Pain was most prevalent at the lumbar spine (32.8%), knee (25.3%), and hip (22.5%), and OA at the knee (13.4%), hip (10.4%), and lumbar spine (4.6%). Injury was associated with pain at the hip (aOR 4.88; 95% CI, 1.87–12.72, p = 0.001), knee (aOR 2.35; 95% CI, 1.45–3.81, p = 0.001), and lumbar spine (aOR 2.53; 95% CI, 1.63–3.92, p < 0.001); OA at the hip (aOR 5.97; 95% CI, 1.59–22.47, p = 0.008) and knee (aOR 3.91; 95% CI, 2.21–6.94, p < 0.001); and joint replacement at the hip (aOR 8.71; 95% CI, 2.13–35.63, p = 0.003) and knee (aOR 5.29; 95% CI, 2.39–11.74, p < 0.001).ConclusionThe lifetime prevalence of Olympic career injury was 56.6%, with those injured more likely to self-report current pain and/or OA at the hip, knee, and lumbar spine and joint replacement at the hip and knee.
