Prevalence and Patterns of Sport Supplements Use among Gym Attendants and Competitive Athletes in North Cyprus

Aims: The purpose of this study was to analyze and compare the prevalence, motivation for use, information and purchase sources of supplements among male competitive team sports athletes and recreational gym users in North Cyprus. Study Design: The sample size was calculated based on the total population size according to the reports obtained from the gyms and the records of the related federations (soccer, basketball, volleyball) of TRNC. For a confidence level of 95 % and a confidence interval of 2.5 %; the required sample size was calculated as 804. The study covered more participants to ensure the statistical power to remain over 80 %. Calculations were performed with G*Power (for Mac Version 3.1.9.3). Place and Duration of Study: 8 gyms located in 6 different districts in Northern Cyprus between june2020 and July 2020. Methodology: A structured questionnaire measuring prevalence and patterns of supplements was administered to 902 participants (329 gym attendants, 562 team sports athletes, 18-40 years old, men). Statistical differences between sex, age group and sports participation were done by using a Chi-square analysis. Differences were considered significant at a p-value <0.05. Results: Overall, 54% of all subjects reported use of dietary supplements, showing a significantly higher percentage among gym attendants (62%) compared to team sport athletes (50%). The most popular dietary supplement among all subjects was protein (46.9%), followed by amino acids (22.6%), multivitamins (20.7%) and creatine (18.8%). Overall, the most important reasons for using supplements were increasing strength (52%), increasing energy (37.6%), insufficient nutrition (32.4%) and increase durability (32.4%). Trainers were the most common source of information for both groups and overall (33.5%), followed by gym friends for the gym attendants and pharmacies for the team sport athletes (30.2%). Conclusion: The prevalence was higher among the gym attendants compared to competitive athletes. This finding is in conflict with the related literature. It might be explained by the low level of competition and athletic performance in North Cyprus. The most popular source of information was trainers in our study and these findings were in compliance with the related literature.

Psychosocial Risk Factors for Overuse Injuries in Competitive Athletes: A Mixed-Studies Systematic Review

Background While the psychosocial risk factors for traumatic injuries have been comprehensively investigated, less is known about psychosocial factors predisposing athletes to overuse injuries. Objective The aim of this review was to systematically identify studies and synthesise data that examined psychosocial risk factors for overuse injuries in athletes. Design Systematic review. Data Sources MEDLINE, Web of Science and PsycINFO databases, supplemented by hand searching of journals and reference lists. Eligibility Criteria for Selecting Studies Quantitative and qualitative studies involving competitive athletes, published prior to July 2021, and reporting the relationship between psychosocial variables and overuse injury as an outcome were reviewed. This was limited to academic peer-reviewed journals in Swedish, English, German, Spanish and French. An assessment of the risk of bias was performed using modified versions of the RoBANS and SBU Quality Assessment Scale for Qualitative Studies. Results Nine quantitative and five qualitative studies evaluating 1061 athletes and 27 psychosocial factors were included for review. Intra-personal factors, inter-personal factors and sociocultural factors were found to be related to the risk of overuse injury when synthesised and reported according to a narrative synthesis approach. Importantly, these psychosocial factors, and the potential mechanisms describing how they might contribute to overuse injury development, appeared to be different compared with those already known for traumatic injuries. Conclusions There is preliminary evidence that overuse injuries are likely to partially result from complex interactions between psychosocial factors. Coaches and supporting staff are encouraged to acknowledge the similarities and differences between traumatic and overuse injury aetiology.

Remained Large Bone Fragment of Bony Bankart Lesion in Shoulders With a Subcritical Glenoid Defect at Recurrent Anterior Instability

Background: A preoperative glenoid defect of 13.5% or larger is recognized as a subcritical glenoid defect at arthroscopic Bankart repair (ABR) for collision/contact athletes or military personnel. Purpose: To clarify the prevalence and size of remaining bone fragments in shoulders with a subcritical glenoid defect at recurrent anterior instability and to investigate the influence on postoperative recurrence after ABR for younger competitive athletes. Study Design: Cohort study; Level of evidence, 4. Methods: The study included 96 shoulders with recurrent instability that underwent ABR between July 2011 and March 2018 for shoulders with a subcritical glenoid defect. The patients were divided into 2 groups according to the glenoid defect size (13.5%-<20%, medium; ≥20%, large). The bone fragment size in each defect group was retrospectively investigated and classified into 4 groups (no, 0%; small, >0%-<5%; medium, 5%-<10%; large, ≥10%). The postoperative recurrence rate for each combination of glenoid defect size and bone fragment size was investigated for competitive athletes aged <30 years. The fragments, when present, were repaired to the glenoid. Results: The glenoid defect size was 13.5%-<20% in 60 shoulders (medium defect group) and ≥20% in 36 shoulders (large defect group). The mean bone fragment size was 6.7% ± 5.1% and 8.9% ± 4.9%, respectively ( P = .042). In the medium defect group, there were 15 shoulders (25%) without a bone fragment, 6 shoulders (10%) with a small fragment, 23 shoulders (38.3%) with a medium fragment, and 16 shoulders (26.7%) with a large fragment. In the large defect group, the respective numbers were 2 shoulders (5.6%), 6 shoulders (16.7%), 14 shoulders (38.9%), and 14 shoulders (38.9%). A medium or large bone fragment was more common in the large defect group ( P = .252). Among 64 younger competitive athletes who underwent ABR with a minimum of 2 years of follow-up, postoperative recurrence was recognized in 7 of 38 (18.4%) athletes in the medium defect group, but it was not recognized in any of the 26 athletes in the large defect group ( P = .036). Postoperative recurrence was recognized in 4 of 12 (33.3%) athletes with a small fragment or no fragment and in 3 of 52 (5.8%) athletes with a medium or large fragment ( P = .019). Conclusion: A larger bone fragment frequently remained in shoulders with a subcritical glenoid defect at recurrent instability. The postoperative recurrence rate after ABR for younger competitive athletes was low when a remaining larger bone fragment was repaired.

SARS-CoV-2 infection and return to play in junior competitive athletes: is systematic cardiac screening needed?

BackgroundSARS-CoV-2 infection might be associated with cardiac complications in low-risk populations, such as in competitive athletes. However, data obtained in adults cannot be directly transferred to preadolescents and adolescents who are less susceptible to adverse clinical outcomes and are often asymptomatic.ObjectivesWe conducted this prospective multicentre study to describe the incidence of cardiovascular complications following SARS-CoV-2 infection in a large cohort of junior athletes and to examine the effectiveness of a screening protocol for a safe return to play.MethodsJunior competitive athletes suffering from asymptomatic or mildly symptomatic SARS-CoV-2 infection underwent cardiac screening, including physical examination, 12-lead resting ECG, echocardiogram and exercise ECG testing. Further investigations were performed in cases of abnormal findings.ResultsA total of 571 competitive junior athletes (14.3±2.5 years) were evaluated. About half of the population (50.3%) was mildly symptomatic during SARS-CoV-2 infection, and the average duration of symptoms was 4±1 days. Pericardial involvement was found in 3.2% of junior athletes: small pericardial effusion (2.6%), moderate pericardial effusion (0.2%) and pericarditis (0.4%). No relevant arrhythmias or myocardial inflammation was found in subjects with pericardial involvement. Athletes with pericarditis or moderate pericardial effusion were temporarily disqualified, and a gradual return to play was achieved after complete clinical resolution.ConclusionsThe prevalence of cardiac involvement was low in junior athletes after asymptomatic or mild SARS-CoV-2 infection. A screening strategy primarily driven by cardiac symptoms should detect cardiac involvement from SARS-CoV-2 infection in most junior athletes. Systematic echocardiographic screening is not recommended in junior athletes.

Asian Pacific Society of Cardiology Consensus Recommendations for Pre-participation Screening in Young Competitive Athletes

Sports-related sudden cardiac death is a rare but devastating consequence of sports participation. Certain pathologies underlying sports-related sudden cardiac death could have been picked up pre-participation and the affected athletes advised on appropriate preventive measures and/or suitability for training or competition. However, mass screening efforts – especially in healthy young populations – are fraught with challenges, most notably the need to balance scarce medical resources and sustainability of such screening programmes, in healthcare systems that are already stretched. Given the rising trend of young sports participants across the Asia-Pacific region, the working group of the Asian Pacific Society of Cardiology (APSC) developed a sports classification system that incorporates dynamic and static components of various sports, with deliberate integration of sports events unique to the Asia-Pacific region. The APSC expert panel reviewed and appraised using the Grading of Recommendations Assessment, Development, and Evaluation system. Consensus recommendations were developed, which were then put to an online vote. Consensus was reached when 80% of votes for a recommendation were agree or neutral. The resulting statements described here provide guidance on the need for cardiovascular pre-participation screening for young competitive athletes based on the intensity of sports they engage in.
