Unbalanced number formats (4v2, 4v4 and 4v6) were performed on a 30 × 25 m playing area, 4 sets of 4 min each with 4 min of active recovery between bouts, under opposition- and cooperation-based perspectives. Data were collected on External Workload (Walking, Running, Sprinting, Max speed and Sprint number), Internal Load of Perceptions (Rating of Perceived Exertion, RPE) and Tactical Individual Actions (Max passing speed, Passing number and with Dominant and Non-dominant foot). An Independent Samples T-Test and Cohen’s d Effect Sizes were conducted to compare both groups. A higher number of differences were observed on the cooperation-based perspective. Generally, foreign players performed more tactical individual actions and intensive external workload. In contrast, Chinese players walked more and scored higher RPE. On this basis, it appears that foreign players have a better team-play experience and ability to adapt to game constraints more easily. This investigation provides insight information about players’ development and to understand the evolution of Chinese soccer that coaches should consider before working on this specific environment.","PeriodicalId":49049,"journal":{"name":"International Journal of Performance Analysis in Sport","volume":"23 1","pages":"343 - 355"},"PeriodicalIF":2.1,"publicationDate":"2023-07-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"43764074","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}

The results showed that the attack organisation changed depending on the receiver condition, and the attack construction from the reception of the outside hitter near from setter when in zones 2, 3 and 4 presented an off-system characteristic. Thus, the ecological conditions, in which the offensive construction begins, specify the performance in high-level men’s volleyball and that different offensive constructions will generate adaptations in the defensive system and in the attack–defence relationships.

However, coaches worldwide behave differently during their coaching process. Thus, this study aims to: a) compare the coaching behaviour and training activities of the football coaches from China and Spain, and b) explore the impact of different pedagogy on coach’s behaviour and players’ perceptions. Systematic observations and semi-structured interviews were developed for 6 youth coaches from Madrid (n = 3) and Beijing (n = 3). And 16 players randomly selected from each academy were queried their perception. The results showed significant differences in coaching behaviours and training activities between both groups. Madrid coaches used more “playing form” (PF) and achieved greater times of activation (motor participation) during practices, compared to Beijing coaches. Concurrent-instruction was the most used behaviour among coaches from both groups. Moreover, Madrid coaches applied more “positive feedback” whereas Beijing coaches used more “negative feedback”. This phenomenon is related to different educational and pedagogical backgrounds. Positive feedback is recommended to Beijing coaches and “silence” should also be properly used while “instruction” and “hustle” should be carefully used to help players learn to “think” (e.g. decision-making). This study offers a comparative analysis to develop proper strategies for a better player’s development.","PeriodicalId":49049,"journal":{"name":"International Journal of Performance Analysis in Sport","volume":"23 1","pages":"296 - 318"},"PeriodicalIF":2.1,"publicationDate":"2023-06-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"48467227","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}

The data were merged and processed post-match at Kinexon Sports App® (Kinexon Sports & Media GmbH). Match variables regarding physical, technical, and tactical actions were analysed and compared between winning and losing teams using a MANOVA. In addition, a stepwise multiple linear regression was performed with the goal difference as the predicted variable and all match-related statistics as predictor variables. Results indicated that winning teams performed more accelerations, ball possessions, passes, successful passes, and shots than losing ones. The regression analysis indicated that increasing the number of shots, close-pressure actions, recovered ball possessions, and successful passes predict winning. On the other hand, increasing the values of running-to-pressure actions, crosses, long goal kicks, and lost ball possessions is likely to reduce the value of the goal difference. Successful performances in the Bundesliga are explained by safely keeping the ball in possession, progressing towards the opposing goal through short passes and creating goal-scoring opportunities through the central corridor of the pitch.","PeriodicalId":49049,"journal":{"name":"International Journal of Performance Analysis in Sport","volume":"23 1","pages":"284 - 295"},"PeriodicalIF":2.1,"publicationDate":"2023-06-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"46848360","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}

The positions were analysed to provide mean, variability (standard deviation) and irregularity (normalised approximate entropy) for each attack and defence possession (470 and 423, respectively) for the team and positional subgroups (forwards, midcourts and defenders) for 10 collective tactical variables. The effects of collective tactical variables on the probability of scoring were estimated with a logistic-regression version of the generalised linear mixed model, with adjustment for predictor variables; possession duration, score difference, match time, ladder-points difference, and match number. The home team and opposition team displayed a greater probability of scoring when they were able to maintain possession for longer periods of time, extremely short possessions were associated with decreased scoring probability.

The aim is to analyse patterns of line umpire errors at the Wimbledon 2021 with a particular focus on differences between men’s and women’s matches. Data were obtained from the official match reports from 290 matches where the Hawk-Eye system was used to determine the umpires’ calls and used to calculate descriptive statistics and to run different linear regression models. Line umpires made 1 error per 17.7 games, with a mean error size of 30 ± 39 mm. Error size on long lines (18 ± 24 mm) was smaller compared to cross lines (40 ± 45 mm), which also served as a significant predictor in all regression models. In women’s matches, we observed a 7 mm bigger mean error size, which was in particular caused by a significantly bigger average error size for erroneous “out” calls (12.2 mm), which could be supported by the regression models. These results help to understand human decision-making performance on the grass. To improve line umpiring, we suggest to put awareness about the nature of line umpire errors, which indeed indicates that the task differs between men’s and women’s matches.

The variables during pole vaulting from the touchdown of the penultimate step on the approach to the peak height of the CG were calculated. Pearson’s correlation analysis and Spearman’s rank correlation were used to test the correlation between maximum CG height and the variables. Significant correlations were observed between the maximum CG height and the six variables (grip height, approach velocity, takeoff velocity, takeoff distance, push height, and maximum vertical velocity). Grip height showed the strongest relationship, followed by push height and takeoff velocity.
