Machine and deep learning for sport-specific movement recognition: a systematic review of model development and performance     

Emily E Cust  Alice J Sweeting  Kevin Ball  Sam Robertson 《Journal of sports sciences》2019,37(5):568-600

Objective assessment of an athlete’s performance is of importance in elite sports to facilitate detailed analysis. The implementation of automated detection and recognition of sport-specific movements overcomes the limitations associated with manual performance analysis methods. The object of this study was to systematically review the literature on machine and deep learning for sport-specific movement recognition using inertial measurement unit (IMU) and, or computer vision data inputs. A search of multiple databases was undertaken. Included studies must have investigated a sport-specific movement and analysed via machine or deep learning methods for model development. A total of 52 studies met the inclusion and exclusion criteria. Data pre-processing, processing, model development and evaluation methods varied across the studies. Model development for movement recognition were predominantly undertaken using supervised classification approaches. A kernel form of the Support Vector Machine algorithm was used in 53% of IMU and 50% of vision-based studies. Twelve studies used a deep learning method as a form of Convolutional Neural Network algorithm and one study also adopted a Long Short Term Memory architecture in their model. The adaptation of experimental set-up, data pre-processing, and model development methods are best considered in relation to the characteristics of the targeted sports movement(s).  相似文献   

Football friends: adolescent boys’ friendships inside an English professional football (soccer) academy     

Adi Adams  Sam Carr 《Soccer & Society》2019,20(3):471-493

This qualitative research draws on data from semi-structured, in-depth interviews to examine the friendships of 12 adolescent (14- and 15-year-old) boys within a professional football club Academy: a setting marked by competition for places. Findings highlight how boys fail to develop ‘deep’ friendships with other boys inside the club; their peer-relationships, even when described as ‘friendships’, are devoid of trust and emotional intimacy. Instead, ‘being mates’ is experienced within parameters of instrumentalism and individualism leading to superficial and inauthentic friendships. There is some indication that boys developed closer friendships with boys outside of the Academy, suggesting that competition is implicated negatively in friendship-building and hinders the capabilities of these boys to develop close friendships with teammates. Concluding this paper, we acknowledge limitations of our data, discuss implications and challenges for football academies, and highlight directions for future research.  相似文献   

Match running performance and skill execution improves with age but not the number of disposals in young Australian footballers     

Paul B. Gastin  Christie Tangalos  Lorena Torres  Sam Robertson 《Journal of sports sciences》2017,35(24):2397-2404

This study investigated age-related differences in maturity, physical and functional characteristics and playing performance in youth Australian Football (AF). Young male players (n = 156) were recruited from 12 teams across 6 age groups (U10–U15) of a recreational AF club. All players were tested for body size, maturity and fitness. Player performance was assessed during a match in which disposals (kicks and handballs) and their effectiveness were coded from a video recording and match running performance measured using Global Positioning System. Significant main effects (P < 0.01) for age group were observed for age, years to peak height velocity, body mass, height, 20 m sprint, maximal speed over 20 m, vertical jump, 20 m multistage shuttle run, match distance, high-speed running distance, peak speed, number of effective disposals and percentage of effective disposals. Age-related differences in fitness characteristics (speed, lower body power and endurance) appeared to transfer to match running performance. The frequency in which players disposed of the football did not differ between age groups, however the effectiveness of each disposal (i.e., % effective disposals) improved with age. Match statistics, particularly those that evaluate skill execution outcome (i.e., effectiveness), are useful to assess performance and to track player development over time. Differences between age groups, and probably variability within age groups, are strongly associated with chronological age and maturity.  相似文献

Socialization experiences and coping strategies of adults raised using spoken language     

Bain L  Scott S  Steinberg AG 《Journal of deaf studies and deaf education》2004,9(1):120-128

This investigation concerned the socialization experiences and coping strategies of a group of 28 deaf adults who were raised using spoken language. Most respondents reported some level of social isolation because of (1) limitations in communication with hearing peers; (2) missing information in social, academic, and work settings; and (3) a sense of being "different." Most participants also reported strategies used to reduce isolation and mitigate the social difficulties associated with their hearing loss.  相似文献   

An exploratory study on collaborative modes of professional development and learning for teachers of students with autism spectrum disorder (ASD)          下载免费PDF全文

Fuk Chuen Ho  Cici Sze‐Ching Lam  Sam Ka‐lam Sam  Michael Arthur‐Kelly 《Support for Learning》2018,33(2):142-164

This study aims to deliver a school‐based mode of training for in‐service teachers of students with ASD in Hong Kong. The training is delivered following the phases of implementation science, namely, exploration, installation, and implementation. The project team used the theory of mind approach, which enables teachers to engage with students with ASD and to focus on recognizing and reacting to emotions. Participants in this study included four educators from a teacher education institution, three expert teachers, and 19 in‐service teacher trainees. The most salient responses came from trainees who were provided with the opportunity to apply learned skills in their own classrooms immediately and to share the knowledge and skills in dealing with students with ASD in the post‐conference meetings.  相似文献   

Physical Space and the Resource-Based View of the College     

Sam J. Fugazzotto 《Innovative Higher Education》2010,35(4):245-259

Space serves as a key resource for colleges and universities, and institutions exchange information about it with each other and with prospective students. Using content analysis to examine several widely circulated publications, this study looked for differences in the value attributed to space when institutional leaders present it to students and to other institutions. More broadly, I hope to suggest how differences in the presentation of space could indicate divergent priorities that can damage institutional trustworthiness.  相似文献
