Drawing from the online Fitness Olympiad database, the data of 8239 children and adolescents from Germany were analyzed by age, sex, and motor performance measured using the Dordel–Koch–test (DKT). Results were compared from the 2010‐2012 and 2018‐2020 cohorts. The results of the 2010‐2012 and 2018‐2020 cohorts were then compared regarding the general and sex‐specific changes in the development of motor performance. A negative trend was shown for three of five motor performance test items, with decreases of 0.9%‐4.8% in abdominal and leg strength and coordination under time pressure, respectively, being found. In contrast, endurance improved by 0.4% and arm and trunk muscle strength by 3.1%. The negative development can be seen as a correlate of exercise deficit disorder (EDD) due to increasing sedentarism. Therefore, the correlation between motor performance and health indicates a clear motivation to appropriately promote the main forms of motor activity.","PeriodicalId":75247,"journal":{"name":"Translational sports medicine","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2021-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"43358877","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}

However, youth may still participate in sport through concussion symptoms and parents may not take their child with a suspected concussion to a physician for assessment and clearance to return to sport. This study uses qualitative methodology to explore parent and coach experiences with concussion management in youth ice hockey. Potential barriers and facilitators to a coach removing a player from play following a suspected concussion and parents taking their child to see a physician are highlighted. We purposively selected twenty‐four hockey parents and coaches in Calgary, Canada, and interviewed them to understand their experience managing youth following a suspected concussion. Using thematic analysis, we highlight barriers and facilitators to coaches appropriately removing a player from participation and parents taking their child to a physician for assessment. Contextual factors including competing priorities, emotional responses, severity of injury, parent and coach beliefs, appropriate communication, and concussion awareness can influence coach and parent concussion management strategies. Coaches, parents, and players play a vital role in facilitating concussion identification and appropriate management. While further education of coaches and parents is indicated, it is important to consider contextual factors that interfere with concussion management behaviors.","PeriodicalId":75247,"journal":{"name":"Translational sports medicine","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2021-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"46228647","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}

VO2peak worsens in patients with chronic renal disease and has been reported to improve in the short term (6‐month time period) following renal transplant. However, long‐term changes in VO2peak following renal transplant remain uncharacterized. We examined changes in VO2peak over ~3 years of follow‐up after renal transplant in 18 patients (age—56.2 ± 2.5 years, BMI—29.7 ± 6). VO2peak was quantified using a treadmill ramp test prior to and following renal transplantation. Subjects were classified as stable vs adverse responders based on changes in VO2peak on follow‐up. Relative VO2peak declined significantly from 15.2 ± 0.8 mL/kg/min to 12.2 ± 0.4 mL/kg/min (~20% reduction) in the entire cohort principally driven by reductions in the adverse response group (n = 10; pre—16.5 ± 1.1, post—11.9 ± 0.5 mL/kg/min) that had greater reductions in VO2peak compared with the stable group (n = 8; pre—13.7 ± 0.7, post—12.5 ± 0.7 mL/kg/min).

A total of 297 elderly men and women were randomized to 1 year of heavy resistance training (HRT) or control (CON). Changes in muscle function and body composition were compared between sexes and groups. Improvements in muscle strength, body fat, muscle mass and size were observed, but the absolute improvements in muscle strength (23 Nm ± 2.3 vs 11 Nm ± 2.2, P < .01) and visceral fat content (−215 g ± 50 vs −60 g ± 21, P < .01) were greater in men. Also, the relative decrease in body fat % (−6.8% ± 1.1 vs −2.7% ± 0.7, P < .05) and fat mass (−7.9% ± 1.4 vs −2.7% ± 1.0, P < .05) was more pronounced in men. Heavy resistance training improved more than CON in most muscular and body composition parameters with greater increase in muscle strength and decrease in body fat in men. Consequently, resistance training is recommendable to counteract age‐related losses of muscle mass and strength and to reduce body fat in elderly, however, with a small advantage for men in parameters that predict metabolic risk factors.","PeriodicalId":75247,"journal":{"name":"Translational sports medicine","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2021-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"43593604","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}

With the known link between reduced muscle size and the health and functioning of the knee joint, it is important rehabilitation programs aim to restore quadriceps mass as safely and quickly as possible. However, a comprehensive review of interventions investigating the impact of training interventions on quadriceps muscle size in ACL‐reconstructed individuals has yet to be undertaken. Therefore, this article systematically reviews the evidence investigating training interventions that aim to improve quadriceps size in ACL‐reconstructed individuals. A literature search was performed in MEDLINE, SPORTDiscus, CINAHL, and Web of Science. Observational and experimental studies investigating training interventions impact on quadriceps muscle size in ACL‐reconstructed individuals were included. Risk‐of‐bias assessment (Downs and Black) was completed on included studies, data was extracted, and a best evidence synthesis was undertaken. 718 articles were returned in the initial search; following screening, six articles were included in this review. Results from the best evidence synthesis suggest there is moderate evidence for eccentrically biased training to increase quadriceps size. Both traditional resistance training and blood flow restriction training showed conflicting results for improving quadriceps size. However, the results for traditional resistance training and blood flow restriction training may have been limited by differing imaging methods across included studies. This review highlights the positive changes in quadriceps size seen following traditional, eccentrically biased and blood flow restriction exercise interventions in ACL‐reconstructed limbs, despite the limited number of studies. Further work is needed to identify and optimize the best practice for hypertrophic training in these individuals.","PeriodicalId":75247,"journal":{"name":"Translational sports medicine","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2021-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"44573081","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}
