Purpose: The aim of this study was to analyse the relationship between absolute and acute:chronic workload ratios and non-contact injury incidence in professional football players and to assess their predictive ability. Methods: Elite football players (n?=?130) from five teams competing in European domestic and confederation level competitions were followed during one full competitive season. Non-contact injuries were recorded and using session rate of perceived exertion (s-RPE) internal absolute workload and acute:chronic (A:C) workload ratios (4-weeks, 3-weeks, 2-weeks and week-to-week) were calculated using a rolling days method. Results: The relative risk (RR) of non-contact injury was increased (RR?=?1.59, CI95%: 1.18–2.15) when a cumulative 4-week absolute workload was greater than 10629 arbitrary units (AU) in comparison with a workload between 3745 and 10628?AU. When the 3-week absolute workload was more than 8319?AU versus between 2822 and 8318?AU injury risk was also increased (RR=?1.46, CI95% 1.08–1.98). Injury incidence was higher when the 4-week A:C ratio was <0.85 versus >0.85 (RR?=?1.31, CI95%: 1.02–1.70) and with a 3-week A:C ratio >1.30 versus <1.30 (RR?=?1.37, CI95%: 1.05–1.77). Importantly, none of the A:C workload combinations showed high sensitivity or specificity. Conclusions: In elite European footballers, using internal workload (sRPE) revealed that cumulative workloads over 3 and 4 weeks were associated with injury incidence. Additionally, A:C workloads, using combinations of 2, 3 and 4 weeks as the C workloads were also associated with increased injury risk. No A:C workload combination was appropriate to predict injury.  相似文献   

Sport-specific biomechanical responses to an ACL injury prevention programme: A randomised controlled trial

Anterior cruciate ligament (ACL) injury prevention programmes have not been as successful at reducing injury rates in women’s basketball as in soccer. This randomised controlled trial (ClinicalTrials.gov #NCT02530333) compared biomechanical adaptations in basketball and soccer players during jump-landing activities after an ACL injury prevention programme. Eighty-seven athletes were cluster randomised into intervention (6-week programme) and control groups. Three-dimensional biomechanical analyses of drop vertical jump (DVJ), double- (SAG-DL) and single-leg (SAG-SL) sagittal, and double- (FRONT-DL) and single-leg (FRONT-SL) frontal plane jump landing tasks were tested before and after the intervention. Peak angles, excursions, and joint moments were analysed using two-way MANCOVAs of post-test scores while controlling for pre-test scores. During SAG-SL the basketball intervention group exhibited increased peak knee abduction angles (p = .004) and excursions (p = .003) compared to the basketball control group (p = .01) and soccer intervention group (p = .01). During FRONT-SL, the basketball intervention group exhibited greater knee flexion excursion after training than the control group (p = .01), but not the soccer intervention group (p = .11). Although women’s soccer players exhibit greater improvements in knee abduction kinematics than basketball players, these athletes largely exhibit similar biomechanical adaptations to ACL injury prevention programmes.  相似文献

困境与出路：我国性侵运动员犯罪行为的刑事规制探究          下载免费PDF全文

王桢 《河北体育学院学报》2019,33(1):19-27

近年来，性侵运动员的犯罪行为频发，成为国际社会聚焦的热点。以此审视我国运动员性法益的保护，虽有强奸罪、强制猥亵罪的刑事立法，却缺乏对该犯罪行为特殊性的深入思考，既不能在惩治犯罪人方面达到理想效果，亦不能在预防犯罪方面发挥良好功能。同时，司法中的“以纪代法”、针对性缺乏、未回应被害人需求等诸多问题，亦使该犯罪行为的刑事规制效果大打折扣。所以，在该犯罪立法上应有针对性采用附属刑法进行修正，完善犯罪的特别预防与一般预防制度；司法上，积极回应被害人的诉求，努力克服刑事规制过程中的各种困境，让运动员的性法益得到全面而充分的保护。  相似文献   

eHealth literacy and the motivators for HPV prevention among young adults in Kenya     

Nancy Muturi 《Communication Research Reports》2020,37(3):74-86

ABSTRACT

The human papillomavirus (HPV) is one of the most common but preventable sexually transmitted infections that affect males and females but knowledge about it and vaccine uptake remain low. As organizations adopt eHealth communication strategies to communicate about HPV, this study examines the association between eHealth literacy (and related elements) and the motivators for HPV prevention that are based on the protection motivation theory. A survey was conducted among 472 young adults in Kenya and results show moderate eHealth literacy (M = 3.21, SD = 1.03) and online information seeking (M = 3.57, SD = 1.08) but low HPV knowledge and risk perception. eHealth literacy was correlated with HPV knowledge, perceived risk, self-efficacy, and response efficacy whereas online health information seeking were correlated with perceived seriousness of HPV infection. This study suggests examining the discrepancy between online information seeking and knowledge and the disparities in eHealth literacy among young adults in HPV communication.  相似文献   

A situational crime prevention analysis of Anglican clergy’s child protective practices     

《Child abuse & neglect》2018

To date, a predominant focus within the field of ‘clerical collar crime’ has revolved around institutional-level church responses to child sexual abuse events, survivors and offenders. Comparatively, little attention has been directed towards the micro-level and in particular, examining clerical responses to child sexual abuse. This article presents empirical findings concerning the ‘everyday’ child protective practices of Anglican clergy in the Diocese of Tasmania, Australia. Research data was acquired through open-ended qualitative interviews conducted with a sample of 34 clergy in a broader study of clerical culture, habitus and life amidst the ‘church abuse crisis’. The framework of Situational Crime Prevention is employed to evaluate the feasibility of clergy’s child-safe practices and comment on how these practices could be further altered through professional development. Research findings demonstrate that clergy possess an active awareness of risk, and execute a series of protective measures to minimise both sexual interactions with children and allegations of impropriety.  相似文献
