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.","PeriodicalId":75247,"journal":{"name":"Translational sports medicine","volume":"4 1","pages":"627 - 636"},"PeriodicalIF":0.0,"publicationDate":"2021-04-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.1002/tsm2.251","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"44046295","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 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.","PeriodicalId":75247,"journal":{"name":"Translational sports medicine","volume":"4 1","pages":"617 - 626"},"PeriodicalIF":0.0,"publicationDate":"2021-04-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.1002/tsm2.249","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"44944408","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 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.","PeriodicalId":75247,"journal":{"name":"Translational sports medicine","volume":"4 1","pages":"524 - 533"},"PeriodicalIF":0.0,"publicationDate":"2021-04-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.1002/tsm2.248","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"48242339","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 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).

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).

These injuries can be prevented by heavy resistance training of the hamstrings. In animal MTJ, the ultrastructural foldings of tendon into muscle increase with training and decrease with immobilization, but whether this happens in the human MTJ is unknown. Therefore, the aim of this study was to investigate by electron microscopy the effect of 4 weeks heavy resistance training (6 patients) and 5 weeks immobilization (3 patients) on the ultrastructure of the human MTJ, compared to controls (7 patients). Specimens of MTJ were obtained from the semitendinosus and gracilis muscle in connection with harvest of the tendon for reconstruction of the anterior cruciate ligament. We registered the number of branches from the MTJ into muscle, interface length/baseline, length and width of the MTJ unit, and area of the foldings and number of foldings per MTJ unit. There were no significant differences in any measures between the three groups. Adaptations of the human MTJ in connection with heavy resistance training are smaller than the changes reported in animals. Perhaps 4 weeks is too short for the human MTJ to react structurally to loading.","PeriodicalId":75247,"journal":{"name":"Translational sports medicine","volume":"4 1","pages":"431 - 438"},"PeriodicalIF":0.0,"publicationDate":"2021-03-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.1002/tsm2.243","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"45210167","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}

Therefore, the aim was to assess the influence of APF on two clinician‐friendly balance tests: the YBT and RBT, as well as its effects on brain activity. Twenty healthy adults participated in this randomized crossover study. APF was induced by a 30 seconds modified Wingate test. YBT performance was expressed in maximal reach distances, and RBT performance involved visuomotor reaction time and accuracy. Electroencephalography (EEG) was used to measure brain activity during these balance tests. Balance test performance and EEG recordings were analyzed pre‐post. APF was successfully induced given that secondary outcome measures (eg, heart rate, blood lactate concentration) significantly increased following the modified Wingate. Decreased RBT accuracy was observed after APF, yet YBT performance and RBT visuomotor reaction time were unaffected. APF induced spectral power increments in the brain during both YBT and RBT performance.","PeriodicalId":75247,"journal":{"name":"Translational sports medicine","volume":"4 1","pages":"488 - 499"},"PeriodicalIF":0.0,"publicationDate":"2021-03-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.1002/tsm2.242","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"46994895","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}
