Research has also demonstrated that novice performance is improved when instructed to focus on skill execution processes rather than outcomes. However, this effect remains untested in complex jumping skills crucial to numerous sports.PurposeThis study aimed to investigate the effect of internally and externally directed process and outcome focus instructions on approach jump height and approach speed in novice participants.MethodsTwelve individuals aged 18 to 22 participated across three sessions: Familiarization, Test Session 1, and Test Session 2. During the test sessions, participants executed approach jumps in various conditions, each emphasizing specific cues: External Focus-Outcome, Internal Focus-Outcome, External Focus-Process, and Internal Focus-Process. Jump-and-Reach Height, Estimated Jump Height by Flight Time, and Approach Speed were assessed through 2 × 2 repeated measures ANOVAs.ResultsExternal focus and outcome conditions led to the highest jump-and-reach height ( p < .05). Process conditions yielded faster approach speed compared to outcome conditions ( p < .001), irrespective of internal or external focus direction. Estimated jump height by flight time was similar across all conditions.ConclusionsThe study suggests that benefits of external focus and process instructions for novices may apply only to certain performance variables in complex motor skills.Practical ApplicationsPractitioners can optimize novices’ performance using various process- and outcome-based instructions. External, outcome-based cues enhance overall task performance, while process-based cues may improve specific technical components.","PeriodicalId":47767,"journal":{"name":"International Journal of Sports Science & Coaching","volume":"8 1","pages":""},"PeriodicalIF":1.9,"publicationDate":"2024-08-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142215174","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"教育学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, as coach education programmes and coach development systems seek to enhance the knowledge and skills of coaches, there is a need to investigate the effects that these initiatives have on coaching practices. The purpose of this multi-methods study was to investigate the effectiveness and perceived benefits of the Values and Principles in Sport (VPS) coach education course, specifically regarding values-driven coaching practices. Twenty-seven coaches and athletes from their teams ( n = 85) participated in the study. Fourteen coaches attended the VPS course, which aimed to equip coaches with knowledge and skills for promoting values-driven coaching practices. Among this group, quantitative data were collected using a coach-centric systematic observation tool and an athlete survey, while qualitative data were collected through individual interviews with coaches and focus groups with athletes. Additionally, the 13 coaches who did not attend the VPS course – as well as athletes from their teams – were included in a control group and completed the quantitative measures. Quantitative results that are related to teaching values suggest that coaches who attended the VPS course did not perform better than those in the control group. However, the course did impact coaching style, suggesting high inter-individual differences in coaching styles (i.e., reserved, average, engaging, purposeful, and VPS-active). Qualitative results highlight that, among coaches who attended the VPS course, the course contributed to understanding and awareness related to teaching values in sport and the transfer of values outside of sport. Taken together, the study underscores the value of incorporating practical components in designing a VPS course, as well as the potential for individualising coach development pathways based on coaching style.","PeriodicalId":47767,"journal":{"name":"International Journal of Sports Science & Coaching","volume":"38 1","pages":""},"PeriodicalIF":1.9,"publicationDate":"2024-08-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142215169","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"教育学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This study deploys a data-driven approach to examine the occurrence of squad rotation across English, French, Italian and Spanish leagues over multiple seasons. It aims to establish the relationship observed between average squad rotations in starting lineups and end-of-season points. A total of 16,720 matches dating from the 2010/11 to 2021/22 seasons were analysed for average rotations in each team involved and the respective team's end of season points, alongside contextual information such as injury and logarithmic market value. A linear mixed-effects model was used to study this relationship, with each variable as well as interaction of variables being analysed for fixed effects. The results show that a significant relationship exists between team success, average rotation of the team per match and market value of the team, while no significant effects are found for injuries. The results describe how universally deploying squad rotation may not yield higher points over a season, but also shows how the effect of rotations on team success keep increasing as the market value of teams increases.","PeriodicalId":47767,"journal":{"name":"International Journal of Sports Science & Coaching","volume":"54 1","pages":""},"PeriodicalIF":1.9,"publicationDate":"2024-08-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142215219","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"教育学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Thirty-one male sprinters performed 60-m sprints during which the GRF from the start to the 50-m mark were measured. The vertical, braking and propulsive RFDs at each step were calculated as the average rate of change in GRF. Average values for each four steps during the acceleration phase were calculated to examine relationships between running speed or average horizontal external power (AHEP) and RFD values. The RFD values ranged from 859.8 ± 191.1 to 1682.0 ± 258.2 N/s/kg for vertical force, −502.6 ± 215.7 to −1033.8 ± 196.2 N/s/kg for braking force, and 97.2 ± 11.7 to 185.4 ± 32.3 N/s/kg for propulsive force. There were associations of running speed with vertical RFD at the 21st–24th step section (r = 0.385) and with propulsive RFD at the 1st–4th step section and from the 13th–16th to 21st–24th step sections (r = 0.386–0.559). Moreover, AHEP was correlated with vertical RFD from the 13th–16th to 21st–24th step sections (r = 0.442–0.523), with braking RFD at the 17th–20th and 21st–24th step sections (r = −0.423 and −0.448), and with propulsive RFD at every step section (r = 0.374–0.856). In conclusion, greater propulsive RFD throughout the acceleration phase, along with higher braking and vertical RFD during the later acceleration section, may indicate better sprint performance.","PeriodicalId":47767,"journal":{"name":"International Journal of Sports Science & Coaching","volume":"2 1","pages":""},"PeriodicalIF":1.9,"publicationDate":"2024-08-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142215170","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"教育学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

BMT was expressed as a Z-score comparing each player's percentage of predicted adult height (%PAH) to age-specific means and standard deviations reported in the: Berkeley Growth Longitudinal (US), UK 1990 growth reference (UK), and Swedish 2000s growth reference (SWE) studies. Multinomial logistic regression was used to compare BMT classification (Early, On-time, Late) between datasets. One-sampled means t-tests were used to examine BMT-related maturity biases per cohort and reference dataset. For both Swedish U15 ( p < 0.001) and Irish U13 ( p = 0.003) players, BMT classification was significantly influenced by the selection of the growth reference dataset. Only 61% of players had the same BMT category across all reference datasets. Significant maturity biases existed in favour of early maturing Swedish players (mean = 96.5%PAH) in all datasets, although moderate using SWE ( d = 0.7), large using UK ( d = 1.02), and very large using US ( d = 1.36) (all p < 0.001). Small significant maturity biases existed in favour of early maturing Irish players (mean = 87.1%PAH) using UK ( p < 0.001, d = 0.48) and US ( p < 0.001, d = 0.33), but not SWE. We conclude that maturity Z-scores must be interpreted with significant caution, given the large variations in BMT classification between reference datasets.","PeriodicalId":47767,"journal":{"name":"International Journal of Sports Science & Coaching","volume":"32 1","pages":""},"PeriodicalIF":1.9,"publicationDate":"2024-08-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142215171","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"教育学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This study's primary focus was to explore athlete's coping strategies throughout the menstrual cycle. Participants ( n = 12) took part in a focus group or interview, facilitated by reflections from a diary and mapping exercise. Reflexive thematic analysis was used to analyse the data, generating three themes: Impact of symptoms, coping strategies, and contextual constraints. Participants had increased awareness of physiological over psychological fluctuations, and associated symptoms were considered to impact practicalities of sport and performance. Participants used avoidance, acceptance, and planning to cope with the impact of menstrual symptoms. Coping options were influenced by contextual constraints, including the level of competition and type of sport. The findings showed that some participants lacked menstrual health literacy, especially in relation to psychological fluctuations. Continued efforts to raise awareness around the psychological symptoms of the menstrual cycle and its impact on performance and well-being are needed, not only for the athlete but importantly for the coaching population too. Specifically, consideration of the sporting culture and the space in which athletes feel they can communicate their coping strategies could be pivotal in moving forwards to help develop ‘period pro’ athletes.","PeriodicalId":47767,"journal":{"name":"International Journal of Sports Science & Coaching","volume":"13 1","pages":""},"PeriodicalIF":1.9,"publicationDate":"2024-08-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142215172","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"教育学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This fails to acknowledge the dynamism of PA and given increased investment and employment of analysts in professional soccer, scrutiny of the current processes and duties associated with the role would seem timely. To this purpose, eight full-time analysts in the English Football League (EFL) and English National League (National League) participated in in-depth semi-structured interviews and transcripts were subjected to inductive reflective thematic analysis. The data analysis revealed two higher-order categories (Flying solo / Coach control) and four themes classified as lower-order ( PA pragmatism / Identifying indicators / The reticent coach / Autocratic presentations). The findings of this study highlight that the responsibilities of the performance analyst range from acting on their own initiative to responding to requests and instructions from the coach. Subsequently, the responsibility for individual actions/activities related to PA is dependent on what aspects of analysis are to be used, who is the recipient of the data/video/presentation, when in the relationship between analyst and coach the activities are developed and when in the match-play process they are carried out.","PeriodicalId":47767,"journal":{"name":"International Journal of Sports Science & Coaching","volume":"274 1","pages":""},"PeriodicalIF":1.9,"publicationDate":"2024-08-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142215176","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"教育学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This study focuses on an unsystematic element of goal scoring, namely rebounds, where a shot that bounces back from another player or the goal creates contested opportunities. Aspects including causes, match situation, player positioning and pitch zones were investigated for 554 rebound goals from seven seasons (2012/2013–2018/2019) of the English Premier League. Rebounds were predominantly caused by short distance and defensive errors, with goalkeepers playing a crucial role. Interestingly, the superiority of home teams and stronger teams to score significantly more goals than away teams and weaker teams can also be observed for rebound goals. Rebound goals are particularly prevalent in zones close to the goal, more prevalent after corners than non-rebound goals and associated with a high number of players in the penalty box. Overall, high similarities exist between rebound and non-rebound goals, while differences in match situations and spatial patterns suggest unique characteristics of rebound goals. These results are in line with the notion of systematicity and randomness concurrently contributing to success in football. More research appears useful to further disentangle the influence of both factors.","PeriodicalId":47767,"journal":{"name":"International Journal of Sports Science & Coaching","volume":"17 1","pages":""},"PeriodicalIF":1.9,"publicationDate":"2024-08-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142215173","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"教育学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
