Sixteen matches were selected and 1925 units of observation were analysed, of which 8095 events were recorded using the HandballTAS tool (Handball Tactic Analysis System). The variables analysed to determine offensive effectiveness were individual actions, offensive punishment, degree of opposition, field area, location, numerical situation, and duration. The data were subjected to multivariate analysis in the form of binary logistic regression and classification tree. The classification and regression model correctly classified 81.6% of the dependent variables on offensive effectiveness (assist and numerical situation, p<0.05; field area and location, p<0.001). Offensive effectiveness increases with an assist (53%) and decreases with a shot from the wing-shots (53%), and with a 9-metre shot (65%) compared with a 6-metre shot. In respect of location, efficacy was reduced by 69% with shots in the middle zone of the goal when compared with shots in the lower zone. The probability of success was reduced by 49% in the warning of the passive play situation and 43% in the inferiority situation compared to the equality situation.","PeriodicalId":510097,"journal":{"name":"South African Journal for Research in Sport, Physical Education and Recreation","volume":"57 2","pages":""},"PeriodicalIF":0.0,"publicationDate":"2023-12-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"139184545","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}

This study explored recreational and certified rock climbers’ attitudes regarding certification, social pressure to obtain certification and the extent of control over certification. A qualitative design was used to interview a total of 28 participants; 11 participants were Mountaineering Development and Training Trust (MDT) certified and five participants were South African Qualifications Authority (SAQA) qualified. The remaining 12 participants had no formal training and were non-certified. Data were collected in-person through semi-structured one-on-one interviews. The theory of planned behaviour was used as a theoretical framework to analyse the perceptions of rock climbers of certification in South Africa. The findings showed that the perceptions of non-certified rock climbers might be based on incorrect information. This may lead to certification being considered unnecessary when social pressure is not present. Furthermore, participants argued that only professional guides need proper training; in contrast, instructors teaching climbing did not need the same qualification. Ultimately, a change in the attitude of rock climbers towards the need for training could result in an internationally recognised South African rock-climbing industry with higher safety standards and fewer accidents.","PeriodicalId":510097,"journal":{"name":"South African Journal for Research in Sport, Physical Education and Recreation","volume":"16 5","pages":""},"PeriodicalIF":0.0,"publicationDate":"2023-12-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"139184437","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}

The highly competitive nature of inter-school leagues often prioritises short-term success over long-term player development. The study compared successful and less successful teams in various talent development environments (TDE) and team cohesion variables based on the log position of a high school’s tournament (u/15 and u/18 age-groups) and established correlations between these variables. A cross-sectional design was used, and 146 boys (average age: 15.51±1.23 years) completed the Talent Development Environment Questionnaire (TDEQ-5) and the Youth Sport Environment Questionnaire (YSEQ) before the 2020 Mazinter Cup. The top three u/18 teams had significantly higher TDEQ-5 (Overall), Alignment of Expectations, Support Networks, YSEQ (Overall Cohesion), Task Cohesion and Social Cohesion scores than the bottom three teams. The results underscore the well-established cohesion–performance relationship. There were no differences at the u/15 level, where players competed in this age-group for the first time. Moderately strong positive correlations existed between various TDEQ-5 and YSEQ variables. Fostering team cohesion is integral to successful TDEs. Long-term player development and team success can be pursued simultaneously.","PeriodicalId":510097,"journal":{"name":"South African Journal for Research in Sport, Physical Education and Recreation","volume":"39 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2023-12-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"139184532","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}
