Prior research indicates that providing participants with positive augmented feedback tends to enhance motor learning and performance, whereas the opposite occurs with negative feedback. However, the majority of studies were conducted with untrained participants performing unfamiliar motor tasks and so it remains unclear if elite athletes completing familiar tasks respond in a similar fashion. Thus, this study investigated the effects of three different versions of false-performance feedback on punching force (N), pacing (force over time) and ratings of perceived exertion (RPE) in 15 elite amateur male boxers. Athletes completed a simulated boxing bout consisting of three rounds with 84 maximal effort punches delivered to a punching integrator on four separate days. Day one was a familiarisation session in which no feedback was provided. In the following three days athletes randomly received false-positive, false-negative and false-neutral feedback on their punching performance between each round. No statistical or meaningful differences were observed in punching forces, pacing or RPE between conditions (P > 0.05; ≤ 2%). These null results could stem from the elite status of the athletes involved, the focus on performance rather than learning, or they may indicate that false feedback has a less potent effect on performance than previously thought. 相似文献

This paper sets out to appraise (from the perspective of members) the impact of a localized, football-based mental health intervention. Commissioned in late 2015, the ‘Redcar and Cleveland Boot Room (BR)’ was implemented in response to mass redundancy in the local area, coupled with regional suicide rates in men that exceed the national average. Interactive discussions with BR members revealed that: (a) the language of football and shared identity were important for initiating and sustaining engagement in the BR; (b) peer-support and mentoring combined with member-led activities were active ingredients of the BR and (c) that the BR was an effective vehicle for building mental health resilience. This evaluation adds to the evidence base on the value of football as a context to engage adult males in community-based interventions targeting mental health resilience. 相似文献

This study examined the bidirectionality between kindergarten children's executive functioning (EF) and word reading across two time points. Participants were 523 Hong Kong Chinese-speaking children (mean age at Time 2 = 64.59 months; 52.9% male) and their parents. At Time 1, children were administered the measures of EF skills: inhibitory control, attention shifting, working memory and Chinese word reading. They were reassessed with these measures at Time 2 one year later. Results from the cross-lagged panel model revealed that, controlling for child age, gender and parental education levels, children's word reading at Time 1 was significantly predictive of their working memory at Time 2, but that the three EF skills at Time 1 were not predictive of word reading at Time 2. These findings underscored the role of early word reading in promoting children's working memory. 相似文献

ABSTRACT This systematic review and meta-analysis aimed to determine differences in body compositionn between playing standard and age in male rugby union and rugby league athletes. The MOOSE (Meta-analysis of Observational Studies in Epidemiology) guidelines for design, implementation, and reporting were followed. Studies were required to be in male rugby union or league and have body composition as the primary or secondary outcome. Data was required to be presented separately for positional groups and body composition presented as whole-body. A systematic search was performed in PubMed, Cochrane Library, MEDLINE, SPORTDiscus, and CINHAHL via EBSCOhost. 57 studies were included for meta-analysis. Results highlighted significantly higher fat-free mass in senior elite than senior sub-elite or junior elite athletes for all RU and RL forwards. Small and non-significant differences were found in fat mass between rugby union playing standards and age categories. Rugby league senior elite forwards had less fat mass than junior elite forwards. Practitioners should prioritise training and nutritional strategies that maximise fat-free mass development, especially in junior elite cohorts. 相似文献

According to the United Nations Convention on the Rights of the Child, children have a right to have their views listened to, and studies have shown that doing so can improve their motivation and self‐esteem. Accordingly, this systematic literature review sought to investigate how the views of children with an autism spectrum disorder (ASD), who have difficulties with social communication, may be gathered. Searches of electronic databases yielded 20 studies which met the criteria for inclusion. Semi‐structured interviews (SSIs) were popular, but there is tentative evidence that these are better suited to older, or more academically able, participants. Some of the evidence suggests adaptations to make SSIs more accessible to young people with ASD. Initial evidence has also emerged regarding the suitability of focus groups and electronic diaries. More focused evaluation by researchers of the suitability of their chosen data‐gathering methods for participants with ASD would allow broader conclusions to be drawn. 相似文献
