We examined the perceptions of Danish association football coaches towards the use and engagement with PA. An online survey with 34 open-ended and close-ended questions was completed by 200 UEFA A and Pro Licenced coaches, gaining insights into how the coaches’ engaged with PA, how PA supported their practice and the future of PA in Denmark. Additionally, five male coaches completed a semi-structured interview. UEFA Pro Licenced coaches had greater experience with analysis support and perceived the importance of video for opposition and reviewing their own team’s performance with higher regard than UEFA A Licenced coaches. Cost and time were highlighted as barriers, but a clear desire to have a dedicated performance analyst was acknowledged by all coaches. The research findings provide key considerations regarding the knowledge and understanding of how Danish football coaches review and evaluate performances, highlight the perceived benefits of PA and acknowledge a desire to increase investment. The insights can be used to inform future decision making regarding the direction of PA provision and the education and development of Danish coaches.","PeriodicalId":49049,"journal":{"name":"International Journal of Performance Analysis in Sport","volume":"22 1","pages":"149 - 173"},"PeriodicalIF":2.1,"publicationDate":"2021-12-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"48223936","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}

Spatiotemporal variables were calculated for 13 male hurdlers by capturing hurdle clearances at the same height as their respective CM and hurdle-free sprints with a high-speed camera. Relationships between each variable and the horizontal velocity during hurdle clearance (HC-v), ratio of HC-v to sprint velocity without hurdles (HC-index), rate of deceleration on takeoff (D-takeoff), and rate of deceleration on landing (D-landing) were examined. Results showed that the support time on takeoff was not significantly correlated with the HC-index, and the correlation coefficient with the release height of CM at landing was significantly higher for the HC-index than for the HC-v. After stepwise multiple regression analysis, the following explanatory variables were selected as promising: clearance time for HC-v, long release distance on takeoff and high release height of CM at landing for HC-index, short touchdown distance on takeoff and long release distance on takeoff for D-takeoff, and takeoff–landing distance ratio for D-landing. These results suggest that the spatiotemporal variables that are important for speed, technicality, and low deceleration on takeoff versus on landing during hurdle clearance are different.","PeriodicalId":49049,"journal":{"name":"International Journal of Performance Analysis in Sport","volume":"22 1","pages":"102 - 120"},"PeriodicalIF":2.1,"publicationDate":"2021-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"48048048","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}

Fifty-seven collegiate marching artists completed single- and double-leg stance balance with and without an instrument on firm and foam surfaces (four conditions per stance). Two, 15-s trials of each condition were performed on a tri-axial force plate. Total, antero-posterior, and medio-lateral centre-of-pressure excursion, and 95% ellipse sway area were collected. Means from the two trials were averaged. Linear mixed-effects models were fit with centre-of-pressure variables as predictors with fixed effects of surface and instrument, adjusting for number of seasons in marching band and type of instrument. Alpha level was set a priori at p ≤ 0.05. Standing on foam surface, regardless of stance, elicited longer excursion and larger sway area (p < 0.05 for all). Although number of seasons participated in marching band did not influence static postural control under single-leg stance, there was a significant effect for double-leg stance (p < 0.01). Marching artists commonly rehearse and perform on unstable surfaces. Understanding static postural control performance under similar conditions may provide novel and important information for injury risk assessment and performance evaluation.","PeriodicalId":49049,"journal":{"name":"International Journal of Performance Analysis in Sport","volume":"22 1","pages":"121 - 131"},"PeriodicalIF":2.1,"publicationDate":"2021-11-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"43120032","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}

Moreover, results were aligned to the Development Model of Sport Participationto better understand the developmental trajectories of bowlers and batters. The study consisted of 251 male players from an English professional first-class county cricket club who were categorised into two skill-sets dependant on their match performance data (bowlers: n = 118; batters: n = 133). Bowling and batting averages, as well as wickets taken and runs scored, were used for analysis. No significant differences were identified for bowlers who were successful and unsuccessful in achieving professional status prior to U17. In contrast, batters who achieved professional status displayed significantly superior match performance data throughout the pathway. Overall, this data: (a) provides evidence of performance targets for young aspiring cricketers to achieve expertise in English cricket, (b) highlights that bowlers and batters typically follow different development trajectories, and (c) offers an analytical tool for key stakeholders to develop an evidence-based talent identification programme.","PeriodicalId":49049,"journal":{"name":"International Journal of Performance Analysis in Sport","volume":"22 1","pages":"1 - 15"},"PeriodicalIF":2.1,"publicationDate":"2021-11-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"49214747","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}

Data were analysed from 646, 200m efforts performed by 13 international Paracanoe athletes between 2017 and 2020 (Male: N= 6, female: N= 7) using boat-based GPS unit (Catapult S5). Significant differences between the Paralympic classifications were observed for boat velocity, stroke rate and displacement per stroke across both genders (p < 0.001) and Paracanoe classification (p < 0.001). Stroke rate was found to be the best predictor of boat velocity across classifications explaining between 13% and 34% of the variation. However, displacement per stroke was found to be more important for males than females potentially due to strength and anthropometric differences. Boat velocity, stroke rate and displacement per stroke values for the final 150m (measured in 50 m splits) indicated evidence for a mix of all-out and positive pacing strategies. The results of this study suggest intricate differences exist in Paracanoe Sprint Kayak based on gender and classification between athletes.

The 1-way ANOVA revealed that U-18 and U-20 players produced significantly higher values of relative peak rate of force development (p = 0.015), average rate of force development (p = 0.046), relative power (p = 0.005), peak velocity (p = 0.001) and ultimate jump heights (p = 0.001), in comparison with U-14 and U-16 peers. Correlation analysis showed a significant correlation between the relative peak rate of force development, relative average rate of force development, and relative peak power with SpJ jump height in all age groups. Time series analysis of relative applied peak forces indicated that the U-18 and U-20 players reached their relative maximum applied forces significantly earlier than U-14 and U-16 players (p = 0.021). This study suggests that the increase in the height of the SpJ across age groups in young female players is mainly related to achieving faster time to peak force by increased concentric jump-phase peak velocity. Therefore, the time to peak force can be considered as the significant kinetic contributor to higher SpJ height.","PeriodicalId":49049,"journal":{"name":"International Journal of Performance Analysis in Sport","volume":"22 1","pages":"66 - 76"},"PeriodicalIF":2.1,"publicationDate":"2021-10-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"47054748","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}
