To assess the feasibility of the ‘Daughters and Dads Cricket’ programme. In a single-arm, pre–post study, fathers (n  =  34, 43.1  ±  4.4 years) and daughters (n  =  34, 9.4  ±  1.5 years) from Newcastle, Australia were recruited. The 9-week programme was delivered by trained facilitators and included weekly educational and practical sessions, plus home-based tasks. A priori feasibility benchmarks targeted recruitment (20 dyads), fidelity (≥80%), attendance (≥70%), compliance (≥70%), satisfaction (mean: ≥ 4/5) and retention (≥85%). Preliminary efficacy outcomes included cricket skill proficiency, daughters’ enjoyment in cricket, intention to keep playing cricket and long-term retention in cricket. Feasibility benchmarks were exceeded for recruitment (n  =  34 dyads), fidelity (98% education, 100% practical), attendance (88%), satisfaction (fathers: 4.6 of 5, daughters: 4.8 of 5) and retention (97%). Home-programme compliance fell short of the benchmark (64%). Preliminary efficacy was confirmed with medium-to-large effect size changes in 11 of the 13 daughters’ cricket skill proficiency outcomes. Promising findings were identified for daughters’ enjoyment of cricket, intention to continue playing and long-term retention in cricket. A cricket-focused programme targeting daughters and dads was feasible and led to medium-to-large improvements in cricket skill proficiency among the daughters. Additionally, daughters were engaged with cricket, as shown by high levels of enjoyment, intention to continue playing and their long-term retention. Examining future efficacy in a larger trial is warranted.","PeriodicalId":182483,"journal":{"name":"International Journal of Sports Science & Coaching","volume":"70 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-05-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115637685","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}

With it, the defending team's compact organization, which is considered by practitioners to be an important factor in defense, was repeatedly examined. However, the connection between this defensive principle of play and the defending success remains unclear. Therefore, this study aims to investigate the relation of the principle of playing defensive compact organization to the success of the defense. Based on tracking and event data of 153 games of the German Bundesliga (season 2020/21), the compactness (surface area, spread of the team, and of defending subgroups) and the organization (distances between formation lines) of the defending team was compared between successful and unsuccessful defensive plays. There were almost no differences in the compactness of the whole team, and the organizational measures between successful and unsuccessful defensive plays. The defending subgroup of five defenders closest to the ball showed a higher compactness (smaller surface area and smaller spread) in successful defensive plays compared to unsuccessful ones (−0.08 ≤  d ≤ −0.16). Our results indicate that the compactness of players in areas close to the ball seems crucial for defensive success. However, the compact organization of the entire team does not seem important to regain the ball in defense.","PeriodicalId":182483,"journal":{"name":"International Journal of Sports Science & Coaching","volume":"02 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-05-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123092957","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 constraints-led approach (CLA) induces functional movement variability in practice designs, supporting athlete performance in satisfying task constraints and finding performance solutions to achieve intended task goals. Young male volleyball players were randomly assigned to either a traditional approach (TA) or CLA practice group. Selected spatial-temporal movement coordination variables were recorded, to explore their relations to successful performance outcomes in the attacking phase. Binomial logistic regression was used to verify the association of spatial-temporal movement variables with the percentage of successful attacks. Six spatial-temporal variables were included, and a manual backward stepwise regression was used to remove those which did not contribute to the best predictive model of successful performance. After a 6-week intervention programme, the CLA practice group displayed a significantly higher percentage of successful attack actions, when facing the opposition block. The TA group showed a small increase in successful attack actions after the intervention. The final binomial logistic regression model revealed that the variables ‘lateral deviation of the participants’ centre of mass’ at the planting step and ‘longitudinal deviation of the participants’ centre of mass’ at point of ball contact were the main predictors of successful attacking outcomes. To overcome the opposition's block in volleyball, infusing functional variability in a CLA task design, promoted superior performance in practice. Presumably, greater movement pattern variability emerged in participants to satisfy performance constraints in successful volleyball attacks.","PeriodicalId":182483,"journal":{"name":"International Journal of Sports Science & Coaching","volume":"35 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":"125212687","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}

Similarly, there were no significant differences in jump height or other CMJ variables between sessions ( p > .05). There were small to moderate differences in mean barbell velocity between the first and second 6RM test ( g  =  0.24–0.88), while there were only small differences in mean velocity (MV) between the second and third 6RM test at some of the warm-up loads (40% 6RM: g  =  0.20; 80% 6RM: g  =  −0.47).

Typically, open play is considered beneficial for acquiring tactical skills, whereas specific drills are used to support the development of technical skills like passing and shooting. Therefore, a field-based study was designed to investigate the effectiveness of a Nonlinear Pedagogy (NP) approach in contrast to a classical Deliberate Practice approach to improve passing performance in young developmental soccer players. Forty young male players (age 10 ± 1 years) were randomly assigned to three groups (PLAY, PRACTICE, and CONTROL). The PRACTICE group performed classical passing drills, whereas the PLAY group underwent a NP training regime. Passing skill was assessed before and after a 5-week training program using a standardized passing test according to the German Football Association. Additional retention testing was performed 5 weeks later. The results indicated that, although the test design showed no specificity to the learning environment of the PLAY group, both groups improved passing skills after training, but the PLAY group displayed better results during retention testing (PRACTICE: p = 0.004, d = 0.48; PLAY: p = 0.001, d = 0.53) compared to the PRACTICE group. These findings are suggestive of general transfer learning in dynamic learning environments. The findings indicate that even when there is an emphasis on “technical skill” enhancement, more effective improvement in young development players may be observed through dynamic learning environments. Consequently, this study encourages coaches to design training regimes that afford players to train as they play.","PeriodicalId":182483,"journal":{"name":"International Journal of Sports Science & Coaching","volume":"194 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":"116347820","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 &amp; 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 &amp; 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}
