Objective This study aimed to measure depressive symptoms, anxiety symptoms and psychological well-being among a sample of Super League players, the highest tier of professional rugby league in the northern hemisphere. Methods Between November 2018 and July 2019, a sample of 233 Super League players completed questionnaires that assessed depressive symptoms, anxiety symptoms and psychological well-being. Results Players exhibited normal (85.8%), mild (11.6%) or moderate/severe (2.6%) depressive symptoms. Additionally, players reported normal (67.4%), mild (18.9%) or moderate/severe (13.7%) anxiety symptoms. The mean psychological well-being score across the sample was 25.07 (SD=4.34). 35.2% of players scored below average for this construct. Conclusion The prevalence of mild depressive symptoms, moderate/severe depressive symptoms and mild anxiety symptoms among Super League players preliminary appear higher than in the general population from the UK. Much more research is needed to understand mental health among elite athletes. © Author(s) (or their employer(s)) 2020. Re-use permitted under CC BY-NC. No commercial re-use.

However, individual determinants of pitching performance are more elusive. Objectives The aims of this study were to classify the performance factors associated with baseball pitchers, to identify the methods used to quantify their abilities through all features of the game and to document relationships between performance factors and indicators. Design Scoping review. Data sources Electronic searches of MEDLINE, Academic Search Complete, CINAHL, SportDiscus, PubMed, PsycINFO, Cochrane and of grey literature were undertaken from inception to January 2019. Eligibility criteria for selecting studies Cross-sectional studies that investigated the relationship between performance indicators and individual performance factors in healthy baseball pitchers were selected. Results Thirty-four cross-sectional studies investigating individual potential factors of pitching performance met the inclusion criteria. The primary performance factors investigated were kinematic, kinetic, timing outcomes, personal characteristics, physical tests and range of motion. Shoulder horizontal adduction (SHA), upper torso forward flexion, maximal shoulder external rotation, upper torso rotation angle, upper torso lateral flexion, lead knee flexion (LKF) and forward trunk tilt (FTT) were identified as key kinematic features associated with increased ball velocity. Shoulder proximal force and peak elbow proximal forces were associated with greater ball velocity. Individual performances in jumping tests and body weight (BW) are also associated with pitching performance. Summary/conclusion Based on studies presenting low and moderate risk of bias, we conclude that BW, age and kinematics, such as FTT, LKF, SHA and lateral trunk tilt, are associated with pitching performance. © Author(s) (or their employer(s)) 2020.

Published by BMJ.Introduction Active commuting is an inexpensive and accessible form of physical activity and may be beneficial to health. The aim of this study was to investigate the association of active commuting and its subcomponents, cycling and walking, with cardiometabolic risk factors, physical fitness and body composition in young men. Methods Participants were 776 Finnish young (26±7 years), healthy adult men. Active commuting was measured with self-report. Waist circumference was measured and body mass index (BMI) calculated. Aerobic fitness was measured with bicycle ergometer and muscular fitness with maximal leg and bench press, sit-ups, push-ups and standing long jump. Cardiometabolic risk factors were analysed from blood samples and selected variables (glucose, insulin, triglycerides, high-density lipoprotein cholesterol, low-density lipoprotein cholesterol, as well as systolic and diastolic blood pressure) were further converted to z-score to form clustered cardiometabolic risk. Results A total of 24% used active commuting consisting of 10% of walkers and 14% of cyclists. After adjustments for age, smoking, time of year, leisure-time and occupational physical activities, cycling was inversely associated with the clustered cardiometabolic risk (β=-0.11, 95% CI -0.22 to -0.01), while walking was not (β=-0.04, 95% CI -0.16 to 0.08). However, further adjustment for waist circumference attenuated the associations to non-significant. Moreover, cycling but not walking was inversely associated with BMI, waist circumference and maximal strength, while a positive association was observed with aerobic fitness (p less then 0.05). Conclusion This study shows that cycling to work or study has beneficial associations to clustered cardiometabolic risk, body composition and aerobic fitness in young, healthy adult men. © Author(s) (or their employer(s)) 2020.

Published by BMJ.Objective To determine the effects of following return to activity (RTA) and return to school (RTS) protocols on clinical outcomes for children with concussion. The 12 subquestions of this review focus on the effectiveness of protocols, guidelines and recommendations, and the evidence supporting content of the protocols including rest, exercise and school accommodations. Design Systematic review. [https://www.selleckchem.com/products/enarodustat.html JTZ-951 mouse] Data sources PubMed, MEDLINE, EMBASE, CINAHL, ERIC and manual reference list check. Eligibility criteria for selecting studies Studies were included if they evaluated RTA or RTS protocols in children aged 5-18 years with a concussion or if they reported a rigorous study design that provided evidence for the recommendations. Included studies were original research or systematic reviews. Articles were excluded if they did not report on their methodology or included participants with significant neurological comorbidities. Results The literature search retrieved 198 non-duplicate articles and a total of 13 articles were included in this review.
