Sixteen male basketball players (height 183 ± 9 cm, age 22.6 ± 7 years) were recorded shooting 75 three-point shots. Ball release angle and velocity estimates were used in a nonparametric kernel density estimator (KDE) to identify individual-specific release distributions and optimal release angles. Optimal releases varied among individuals and were 4.3 ± 2.1° higher than minimum velocity releases. Mean release angles were 3.9° higher than the minimum velocity angle (p < 0.001) and only 0.4° below the optimal (p = 0.5). Participants skewed their probability density function (PDF) peaks 0.24° towards the optimal (p = 0.044) further indicating participants seek optimal rather than minimum velocity releases. Individual-specific optimal release angles were strongly correlated with their PDF covariance (r = 0.78, p < 0.001) and weakly correlated to the principal axis aspect ratio (r = −0.40, p = 0.137). These findings illustrate that optimal releases varied among participants and performance may be maximised by each athlete matching their release strategy to their PDF characteristics rather than matching a predetermined optimal release angle.","PeriodicalId":49049,"journal":{"name":"International Journal of Performance Analysis in Sport","volume":"22 1","pages":"393 - 406"},"PeriodicalIF":2.1,"publicationDate":"2022-04-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"48372479","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}

It has been traditionally considered as an important factor during basketball games that needs to be studied under different scenarios (home, away or neutral locations). This study aimed to analyse NBA team’s game-related statistics, pre-shooting combinations and pick-and-roll performances among locations (playing at home, away and in a neutral court) during the COVID-19 season. A retrospective cross-sectional study of the 2019–2020 NBA season (906 games) was carried out. Game-related statistics were gathered from the private company InStat (https://basketball.instatscout.com/). The main results showedthat (i) home-court teams had better performances in points, field goal percentage, rebounds, assists and fouls than away-court teams and neutral-court teams; (ii) home-court teams had better performances than away-court teams or neutral-court teams in transitions and cuts made and (iii) home-court teams and neutral-court teams had similar performances to away-court teams in pick-and-roll and pick-and-pop situations although teams playing away had more attempts. In conclusion, playing at home under different circumstances favours the local team, mainly using a more collective way of play.","PeriodicalId":49049,"journal":{"name":"International Journal of Performance Analysis in Sport","volume":"22 1","pages":"370 - 381"},"PeriodicalIF":2.1,"publicationDate":"2022-04-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"47128023","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, erroneous decision-making can lead referees to repeatedly negatively think about the error, i.e. they begin to ruminate. Previous studies focused on the relationship between decision-making and either physical or psychological load. Here, we examined the combined impact of physical and psychological load on top-class handball referees’ decision-making. N = 73 referees performed the Yo-Yo Test for Referees combined with psychological load induced through instantaneous feedback on the decisions to activate the referees’ rumination-trait, i.e. to test if low and high ruminating referees respond differently to load and feedback. Results indicate no effects of physical load on decision accuracy (i.e. foul vs. no foul), but referees’ reasonings accuracy (i.e. type of foul, punishment) decreased under medium external load. Moreover, low and high ruminating referees did statistically not differ in decision and reasoning accuracy. Results indicate that physical load may not affect decisions, but might affect reasonings. Thus, subsequent studies should incorporate decisions and reasonings in handball referees, especially against the background of referee’s development. For practitioners, the Yo-Yo Test for Referees seems a beneficial tool through the combination of physical likewise psychological load and a rule test in handball.","PeriodicalId":49049,"journal":{"name":"International Journal of Performance Analysis in Sport","volume":"22 1","pages":"352 - 369"},"PeriodicalIF":2.1,"publicationDate":"2022-04-09","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"49623616","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}

Average speed was calculated through distance travelled and time. Results indicated that the high-performance group had significantly (p < 0.05) less distance from the starting line and faster speed when starting than the low-performance group in heavy wind conditions. During the first or third legs with light and medium winds, the high-performance group demonstrated a significantly (p < 0.05) faster average speed in heavy wind and significantly less distance travelled, and faster average speed was observed in all legs. The first half of the high-performance group had significantly (p < 0.05) longer distance travelled than the second half. Significantly faster average speed was observed in light wind. These results may assist in preparing for the tactical and technical requirements during a race and enhance performance in every situation.","PeriodicalId":49049,"journal":{"name":"International Journal of Performance Analysis in Sport","volume":"22 1","pages":"332 - 342"},"PeriodicalIF":2.1,"publicationDate":"2022-04-08","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"46616431","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}

Regarding the second aim, the following variables discriminated winning from losing/drawing teams: % action goals, % 6-m goals, % penalty goals, team fouls, sprints won, steals and % goalkeeper actions shots. However, only % action goals (OR: 1.153), steals (OR: 1.279) and % action shots (OR: 1.093) predicted the match outcome.

Nine international male seam bowlers across 28 test matches (n = 9 home; n = 19 away) were investigated over five years (2015–2019). Seam bowlers wore global positioning sensors during match play fielding to quantify physical demands. Absolute and relative (per hour) distances covered in five velocity bands, total distance, and number of accelerations and decelerations were assessed for each match. Coefficient of variation (CV%) and smallest worthwhile change were used to calculate between-match variability. Mixed linear modelling was used to analyse home vs away matches. Seam bowlers covered up to 50 km, with maximal durations of >21 hours during test match fielding. Small between-match CV% (8.3) were found for maximal velocity with large (CV% = 21–192) between-match variability across most other variables. Greater distances were covered at 15–20 km·h−1 (p = 0.02) and >25 km·h−1 (p = 0.04) when playing at home. The results demonstrated substantial, highly variable physical demands.

Team technical performance in 400 and 180 innings of men’s (2017–2021) and women’s (2019–2021) T20 cricket in the professional leagues in Australia were analysed. Batting performance characteristics appear to be more important than bowling characteristics, which is even more pronounced in women’s T20 cricket. The most important bowling characteristic relate to how quickly the first 3 to 5 batters are dismissed. These determinants of match outcome also reflect the characteristics that explain whole-of-season performance. The determinants of performance in women’s T20 cricket are largely the same as in men’s, although there may be an opportunity for some women’s teams to focus on bowling performance as a decisive factor in their match strategy. The findings of this study indicate specific aspects of batting and bowling performance that can influence the goals of training and the design of match strategies.","PeriodicalId":49049,"journal":{"name":"International Journal of Performance Analysis in Sport","volume":"22 1","pages":"277 - 290"},"PeriodicalIF":2.1,"publicationDate":"2022-03-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"48841534","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}

Interview questions were framed around, 1) the use of video and data analysis, 2) coach-athlete interaction, and 3) learning and development. The importance of data, video, and the effective integration of performance analysis to facilitate comprehensive feedback to maximise learning opportunities was identified. The coach-athlete relationship, and engagement of the athlete within the debriefing process emerged as an aspect needing continual micro-management to ensure ongoing effectiveness. The development of an “open and honest” relationship and a “safe space” to air thoughts and opinions was greatly encouraged. The length of debriefing session did not appear to impact overall engagement. The use of video debriefing to facilitate a coach’s ability to develop the athletes mentally, in addition to their physical boxing capabilities, was a key and standout aspect that should be appropriately considered. The findings add to the limited investigation within boxing, providing insight into the debriefing processes within professional boxing by those on both sides, i.e. the coach and the athlete.","PeriodicalId":49049,"journal":{"name":"International Journal of Performance Analysis in Sport","volume":"22 1","pages":"250 - 260"},"PeriodicalIF":2.1,"publicationDate":"2022-02-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"48634511","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}
