The pathophysiology of extra‐articular biceps disease is not fully understood. The purpose of the study was to assess molecular evidence of inflammation, degradation, and nociception within the 3 separate anatomic zones of the extra‐articular biceps tendon and its confining tunnel. Arthroscopic biopsies were taken from the bicipital tunnel from 11 patients with suspected biceps‐labrum complex disease undergoing subdeltoid biceps transfer to the conjoint tendon. Tissue was analyzed for mRNA expression of various inflammatory mediators including interleukin‐6, interleukin‐1β, transforming growth factor‐β (TGF‐β), matrix metalloproteinase‐13, and substance P precursor. Extra‐articular tissue was compared with intra‐articular tendon (internal control) to determine fold change in expression. Compared to intra‐articular tendon, extra‐articular biceps tendon and synovium have increased levels of these aforementioned mediators, significantly TGF‐β (P = .012). In patients with clinical history of long head of the biceps tendon tendinopathy as well as arthroscopic findings of synovitis, tear, and loose bodies, pro‐inflammatory and degenerative cytokines were upregulated in the extra‐articular tendon. Inflammatory cytokines, degenerative mediators, and pain molecules associated with nociception were found within both the extra‐articular long head of biceps tendon and its constraining fibro‐osseous bicipital tunnel in patients with clinically evident biceps‐labral complex disease.

SARS-CoV-2 infection has emerged as not only a pulmonary but also potentially multi-organ disease, which may cause long-term structural damage of different organ systems including the lung, heart, vasculature, brain, liver, kidney, or intestine. As a result, the current SARS-CoV-2/COVID-19 pandemic will eventually yield substantially increased numbers of chronically diseased patients worldwide, particularly suffering from pulmonary fibrosis, post-myocarditis, chronic heart failure, or chronic kidney disease. Exercise recommendations for rehabilitation are complex in these patients and should follow current guidelines including standards for pre-exercise medical examinations and individually tailored exercise prescription. It is of utmost importance to start exercise training at an early stage after COVID-19 infection, but at the same time paying attention to the physical barriers to ensure safe return to exercise. For exercise recommendations beyond rehabilitation programs particularly for leisure time and elite athletes, more precise advice is required including assessment of sports eligibility and specific return-to-sports exercise programs. Because of the current uncertainty of long-term course of SARS-CoV-2 infection or COVID disease, long-term follow-up seems to be necessary.

Apophyseal injuries are generally believed to run a self‐limiting course, suggesting conservative treatment is indicated. We summarized the long‐term consequences of lower limb apophyseal injuries after conservative treatment. We conducted a systematic review using the Cochrane methodology, and reported findings according to PRISMA. MEDLINE, EMBASE, Cochrane CENTRAL, PEDro, and SPORTDiscus were searched. Studies had to include participants aged 8‐18 years old, with a clinical diagnosis of apophyseal injury in the lower limb, more specifically Sever's disease, Osgood‐Schlatter disease, or Sinding‐Larsen‐Johansson disease, non‐surgically treated, with a minimum follow‐up time of 1 year, and with at least one of the following outcome measures: pain, secondary structural changes, functional outcome, participation in sports, and recurrent or subsequent injury. PROSPERO registration number: CRD42020146412. Twelve studies on Osgood‐Schlatter disease, three studies on Sever's disease, and no studies on Sinding‐Larsen‐Johansson disease met inclusion criteria. Results of studies varied widely. Important limitations were heterogeneity between studies and lack of high‐quality research studies. Apophyseal injuries do not always appear to be self‐limiting, with some patients experiencing pain, secondary structural changes, a worse functional outcome, and difficulty resuming sports after more than 1 year of follow‐up.

Predicting sports injuries is a complex phenomenon given the multitude of risk factors involved and the need for an inciting event. Recent evidence suggests that the acute:chronic workload ratio (ACWR) is a potentially useful tool for quantifying athlete workloads, with athletes at increased risk of injury when the ACWR is higher relative to a lower ACWR. While several team sports have been studied in the ACWR literature, there is a paucity of studies that focus on volleyball athletes, and no studies that use knee pain as an outcome. Furthermore, controversy exists as inconsistent results among studies may be attributed to differences in calculating the ACWR. Our objective was to assess different definitions of the ACWR for predicting knee pain in elite volleyball athletes. We expected to see agreement with the literature in that ACWR would be positively associated with knee pain. We conducted a retrospective, exploratory analysis on a data set from a University varsity volleyball team. Our mixed effect modeling indicated that the coefficient estimates for the ACWR variants were small and statistically insignificant. The variant used did not have a major influence on the relationship with knee pain score, and the strength of the relationship was weak.

The Tegner Activity Scale (TAS) has been used in several Danish studies. However, the TAS has not been cross‐culturally adapted into Danish. We aimed to translate the TAS into Danish and to evaluate its measurement properties in patients with knee disorders. The TAS was translated into Danish following international guidelines. The measurement properties were evaluated in 86 patients (median: 25 years). For reliability, 56 patients completed the scale twice within 9 days. Responsiveness and interpretability were evaluated in 64 patients completing the TAS 6 months later. For reliability, the intraclass correlation coefficient was 0.7 (CI: 0.6‐0.8), the standard error of measurement was 0.7 points (CI: 0.6‐0.9), the smallest detectable change was 2.1 points (CI: 1.7‐2.5), and the limits of agreement were −1.7‐2.4 points. For responsiveness, the correlation between the TAS change score and the Global Rating of Change Scale was 0.3 (CI: 0.1‐0.5). In patients reporting improved knee condition, 55% reported a TAS change score of minimum 1 point. For interpretability, the minimal clinically important change was 0.7 points (SD: 1.4), and no floor or ceiling effects were found. In conclusion, the Danish version of the TAS has acceptable test‐retest reliability. However, the TAS seems less adequate to evaluate changes over time.

For adolescent athletes, data on nutrition behaviors are limited. The present study aimed to evaluate the dietary habits of adolescent sports club participants (SPs) compared with those of non‐participants (NPs). The cross‐sectional study of 1917 adolescents aged 14‐16 was based on data from the Finnish Health Promoting Sports Club (FHPSC) study. The health behavior surveys were conducted among SPs (n = 1093) and NPs (n = 824). Logistic regression was used to test statistical significance of the differences in dietary habits between SPs and NPs. SPs were more likely than NPs to eat breakfast on weekends [89% vs 79%, odds ratio (OR) 1.46, 95% confidence interval (CI) 1.07‐2.01] and to report daily consumption of vegetables (46% vs 32%, OR 1.33, 95% CI 1.04‐1.69) and fat‐free or semi‐skimmed milk (72% vs 55%, OR 1.33, 95% CI 1.04‐1.68). Dietary habits regarded as unhealthy, such as sugared soft drink consumption, were similar between the groups. The aforementioned healthy dietary habits are more frequent in SPs than NPs, and unhealthy dietary habits are equally frequent in the groups. Both adolescent SPs’ and NPs’ dietary habits have deficiencies, like inadequate vegetable and fruit consumption. Sports clubs’ opportunities for adolescents’ healthy eating promotion should be examined.
对于青少年运动员来说，营养行为的数据是有限的。本研究旨在评估青少年体育俱乐部参与者(SPs)与非参与者(NPs)的饮食习惯。对1917名14 - 16岁青少年的横断面研究基于芬兰健康促进运动俱乐部(FHPSC)研究的数据。对SPs (n = 1093)和NPs (n = 824)进行健康行为调查。采用Logistic回归检验SPs与NPs之间饮食习惯差异的统计学意义。SPs比NPs更有可能在周末吃早餐[89% vs 79%，比值比(OR) 1.46, 95%置信区间(CI) 1.07‐2.01]，并报告每天食用蔬菜(46% vs 32%， OR 1.33, 95% CI 1.04‐1.69)和脱脂或半脱脂牛奶(72% vs 55%， OR 1.33, 95% CI 1.04‐1.68)。被视为不健康的饮食习惯，如含糖软饮料的消费，在两组之间是相似的。上述健康饮食习惯在SPs中比在np中更常见，而不健康饮食习惯在两组中同样常见。青少年SPs和NPs的饮食习惯都有缺陷，比如蔬菜和水果的摄入量不足。考察体育俱乐部对青少年健康饮食推广的机会。

Participation in collision sports such as rugby union has inherent risk of injury. The aim of this study was to examine injury patterns and risk factors in adolescent rugby players (U15 years). A prospective injury surveillance study was undertaken involving 26 schools (599 male rugby players, mean age 14.7years). Data were collected over the 2016/17 playing season, with injuries classified by body part and diagnosis. We explored the association between risk factors (demographic/biometric; injury history, protective equipment, training profile, level of play) using cox proportional hazard models with time to injury as the dependent variable. Nearly, 30% of players (178/599) suffered at least one injury. Injury incidence is estimated at 14.7 injuries/1000 match hours. Most injuries occurred in the tackle situation (64.6%, 135/209). Common injury sites were head/face (n = 95, 45.5%), ankle (n = 21, 10.0%), or wrist/hand (n = 15, 7.2%). Concussion (n = 79, 37.8%), wrist/ hand fractures (n = 19, 9.1%), or ankle sprains (n = 16, 7.6%) were the most common diagnoses. Seven concussions (8.9%) resulted in more than 28 days absence from play. A higher risk of injury was associated with: previous concussion (AHR 1.45; 95% CI 1.02 to 2.06), and any previous injury (AHR 1.85; 95% CI 1.23 to 2.78). One in three U15 rugby players sustained an injury over a single playing season. Concussion remains a concern in this age group and should be prioritized in future research.

Patellar tendinopathy is a common injury in athletes. The purpuse was to examine whether extracorporeal shockwave therapy (ESWT) was more effective than placebo in the treatment patellar tendinopathy. Thirty‐six athletes were randomly assigned to receive either three ESWT treatments or three placebo treatments. The primary endpoints were changes in pain while walking, at rest, and when the tendon was squeezed on a 0‐10 numeric rating scale. Secondary outcomes included treatment satisfaction and ultrasonographic outcomes. After 12 weeks, ESWT was more effective than placebo regarding pain while walking, mean difference [MD] 1.4 (P = .011). There was no difference in pain at rest, MD 0.4 (P = .404) or pain when the tendon was squeezed, MD 0.3 (P = .221). Regarding the secondary outcomes, ESWT was more effective than placebo with regard to patient‐rated treatment effect, but no improvements were observed in the ultrasonographic outcomes. Improvement was observed after 12 weeks in the ESWT group regarding pain while walking but not regarding pain at rest, when the tendon was squeezed, and on ultrasonography. These findings provide limited support for the use of ESWT, but the clinical relevance is still unclear.

These findings provide limited support for the use of ESWT, but the clinical relevance is still unclear.","PeriodicalId":75247,"journal":{"name":"Translational sports medicine","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2021-03-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.1002/tsm2.246","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"44454181","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
The objective of this survey was to assess badminton‐related pain and analgesic drug use in recreational as well as competitive badminton players and to identify factors influencing analgesic drug use in order to create effective preventive strategies. A cross‐sectional study addressed all adult badminton players/members registered in the regional badminton association of Saxony, Germany. Badminton‐related pain prevalence and analgesic drug use were assessed. Also, predictors for analgesic drug use were identified. Altogether 247 badminton club members (65% male) participated in the study. Lifetime prevalence of badminton‐related pain was 95%, and one‐year prevalence was 73%. Of the participants with badminton‐related pain during the last year, 56% used analgesic drugs; of the participants without badminton‐related pain during the last year, 31% used analgesic drugs. Significant predictors were players’ attitudes toward analgesics as doping substances, self‐perceived knowledge about effects and side effects, being influenced by others, and self‐perceived “sporting culture” in badminton. A gap between self‐perceived and actual knowledge about adverse effects can be a first starting point for the prevention of dangerous analgesic drug use in badminton.

Our purpose was to investigate the association between right heart dimensions and muscle performance and cardiorespiratory capacity in athletes. We selected 90 men with a mean age of 33.0 ± 8.0 years: strength group (SG), 30 bodybuilders; endurance group (EG), 30 endurance athletes; and control group (CG), 30 healthy non‐athletes. Comprehensive echocardiography and radionuclide angiography allowed the cardiac evaluation. VO2peak was assessed by cardiopulmonary testing, muscle strength by the one‐repetition maximum test (1RM) and the relative strength (RS), and muscle endurance by the maximum repetitions test (MR) with 50% of 1RM. In SG was observed an association between right ventricle (RV) basal diameter and RS bench press (R2 = .188 β = 0.486 P = .017) and between right atrium (RA) area and MR leg press (R2 = .257 β = 0.143 P = .004). In EG was observed an association between RV basal diameter and VO2peak (R2 = .299 β = 0.026 P = .002) and between RA area and VO2peak (R2 = .417 β = 0.092 P ≤ .001). In conclusion, our data suggest that there is an association between right heart dimensions and muscle performance and cardiorespiratory capacity; moreover, muscle strength seems important for understanding cardiac adaptations to training.
