Coaches, players, non-coaching staff and medical personnel in New South Wales (NSW), Australia, were invited to complete a cross-sectional online survey, which was disseminated using a targeted email to two Football NSW member organisations and a social media campaign. Categorical data (including age-groups and sex) are presented as counts and percentages and analysed using a Chi-square or Fisher's exact test. A significance level of 0.05 was used for all analyses. In total 328 players, 55 coaches, 37 non-coaching staff and 16 medical personnel completed the survey (n = 436). Awareness of the 11 + was lowest among non-coaching staff (16.2%) and players (32.6%) but higher among coaches (52.7%) and medical personnel (93.8%). Once aware of the 11 + , 75.8% of all respondents used the program although 89.5% of them did so with modifications. In addition, only 40.0% of players reported completing all three parts of the 11 + program. Veteran players were less likely to complete any type of warm-up compared with junior players (63.7% vs. 96.3%, respectively). Although awareness of the 11 + varied amongst survey respondents, 3 out of 4 respondents who were aware of the 11 + adopted the program. However, respondents reported modifying the 11 + and not completing the program as intended, which suggests modification guidance is required to maintain the efficacy of the 11 + .","PeriodicalId":182483,"journal":{"name":"International Journal of Sports Science & Coaching","volume":"30 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-05-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130225939","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}

For this reason, the aim of the present study was to identify key performance indicators of youth football goalkeepers both defense and attack. The sample was composed of 902 defensive and 896 offensive actions from a convenience sample of 32 matches of 19 teams from the Spanish National Championship of Regional Teams U12. A notational analysis was carried out using an ad hoc instrument to register the technical-tactical actions. Validity was higher than .84. In addition, intra-observer reliability was higher than .90. Classification tree analysis was used to investigate which variables were best predictors of technical actions in defense and precision in attack actions of the goalkeepers. Results showed that in the attacking phase the actions that achieve higher values of precision were those when the ball was played to zone A length and both right and left sides (X26 = 542.034; p = .000). In defense, when the goalkeeper achieve higher values of saves were those when the shot was taken from out of the penalty area and no jump or drop was performed. The present findings contribute to evidence-based practice in fostering young goalkeepers.","PeriodicalId":182483,"journal":{"name":"International Journal of Sports Science & Coaching","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-05-08","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125196948","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}

In Formula Kite, the riders’ technical abilities to reach and maintain high speed are key to achieving performance. The aim of the present study was to analyze Formula Kite riders’ performance during speed tests in practice sessions by combining qualitative descriptions of their lived perceptual experiences “from the inside” with measured correlates of performance. The courses of experience of four expert Formula Kite riders’ speed tests were analyzed, compared, and discussed in relation to their measured Velocity Made Good. Results of the qualitative analyses provide original insight into the fine technical adaptations of the riders in their pursuit of performance. Furthermore, the comparison between the evaluated performance using speed measurements and the perceived performance assessed by the qualitative analysis shows interindividual differences as well as inconsistencies between the two modes of analysis. Based on these results, the present study opens practical perspectives for improving training practices, consisting in “calibrating” the sailors’ perceived performance with measured performance.","PeriodicalId":182483,"journal":{"name":"International Journal of Sports Science & Coaching","volume":"81 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-04-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"132125649","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}

Ninety-five female and male elite/tier 4 (T4) or highly trained/tier 3 (T3) athletes participated using their smartphones. Males repeated the test one week later for reliability analyses. Coaches assessed males’ in-water decision making and females were noted as selected or nonselected for the national team. Although response accuracy was significantly different between T3 and T4 athletes ( p < .001) and correlated with age (rs(88) = 0.43), sex-specific analyses identified that the only significant differences in accuracy were between T3 females and the other three groups (T4 females, T3 males, and T4 males). There was no correlation between males’ accuracy and coach-rated decision making skill, and no difference in accuracy between selected and nonselected females. Reliability analyses comparing performance between weeks revealed an ICC of 0.75, a standard error of measurement of 3.41%, and a significant improvement from week 1 to week 2 among T4 males ( p = .018). Despite associations between accuracy and age, the test was not able to distinguish between more similar groups of athletes. Considering the nonrepresentative design of the test, the construct assessed was declarative game knowledge rather than decision making skill, with the results suggesting that the former is not critical for evaluating elite players. The performance improvement between weeks among T4 males reinforces that video-based designs should be used cautiously in high-performance sport. However, there may still be practical applications for video-based designs, such as in video review sessions or as a pedagogical tool.","PeriodicalId":182483,"journal":{"name":"International Journal of Sports Science & Coaching","volume":"187 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-04-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124743604","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}

Specifically, we compared the influence of time pressure and numerical superiority (through an additional player) on the players’ performance and tactical behaviour in small-sided games (SSGs). Forty under-17 soccer athletes participated in the study. The athletes performed 4 SSGs in the following configurations: numerical equality and time pressure (GR-4 × 4-GR – TP); numerical equality and no time pressure (GR-4 × 4-GR – NTP); numerical superiority and time pressure (GR-5 × 4-GR – TP) and numerical superiority and no time pressure (GR-5 × 4-GR – NTP). Tactical performance was evaluated using the Game Performance Evaluation Tool (GPET), and tactical behaviour using positional data measured by the Global Positioning System. The statistical analysis was performed using two-way repeated measures analysis of variance. There was a better tactical performance in decision-making (0.669 ± 0.135, p = .02 and r = .27) and execution (0.602 ± 0.134, p = .002 and r = .44) of technical-tactical actions in the SSG without the time pressure rule. Furthermore, the space exploration index showed lower values (5.634 ± 0.604, p = .007 and r = .32) in games with time pressure than in games without this rule, and there were no significant differences for player length and width behaviour between protocols. It is concluded that the time pressure rule reduces the exploratory behaviour of the players. Understanding these effects allows coaches to plan better training sessions that address the contents of counter-attacks in SSG.","PeriodicalId":182483,"journal":{"name":"International Journal of Sports Science & Coaching","volume":"16 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-04-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129936329","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}

A total of 1634 games across 5 seasons (2014/2015–2018/2019) were analysed for team and positional TD, HID and SprD. All matches were tracked using TRACAB® Gen-4 HD motion cameras.

In this study, we assess the impact of this rule change with regard to player relief, tactical influence by the coaches and the development of young players. Data were collected from 3652 matches from the top 5 leagues in the Union of European Football Associations (UEFA) rankings and 659 UEFA club competition matches (Champions League and Europa League) in 2 different seasons (pre-rule amendment: 2018/2019 vs. post-rule amendment: 2020/2021), comparing leagues that introduced two additional substitutions with those that did not. The results show that with two additional substitutions, the reduction in player load was increased by 46%. Despite being used infrequently, the rule change resulted in 45% more substitutions and, therefore, greater tactical influence by the coaches. Furthermore, two additional substitutions benefit young players’ development with an 81% increase in playing time. While the aim of the temporary amendment to the laws of the game was achieved with the additional substitutions by compensating for the increased load on the players, coaches’ substitution behaviour shows potential for improvement.","PeriodicalId":182483,"journal":{"name":"International Journal of Sports Science & Coaching","volume":"16 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-03-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"132482404","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 speeches were viewed, transcribed, coded, and analyzed via the Linguistic Inquiry and Word Count (LIWC2015) software program. Actual speeches were compared with natural speech norms and speeches appearing in movies pertaining to American football. In general, the pregame speeches were characterized by use of confident, analytical, motivational, emotionally tinged language that is collectively oriented and present and future focused. The speeches delivered to high school teams were substantially similar to those delivered to intercollegiate teams. The actual speeches differed from natural speech on numerous variables and from the cinematic speeches on some descriptive variables. The findings suggest that actual American football pregame speeches are fundamentally similar to cinematic American football pregame speeches and constitute a distinct form of communication that is tailored to the unique demands of the situation.","PeriodicalId":182483,"journal":{"name":"International Journal of Sports Science & Coaching","volume":"7 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-03-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128662265","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}
