To assess agreement, mean absolute Control-Panel score deviations were calculated using Bland-Altman and Kaplan-Meier plots. Reliability average measures ranged from 0.88 to 0.97. Control Score reliability was higher in ECh for Execution and Artistic scores. Artistic scores showed higher variability and lower agreement between judges in Qualification for ECh. Significant differences were found in Control and Panel score mean deviations for Execution scores at the EAGC and for Artistic scores at the ECh. No significant reliability differences were found between competitions. Control-and-Panel score correlations ranged from 0.862 to 0.915 for Execution scores and from 0.864 to 0.899 for Artistic scores. Overall results exceeded 80% agreement for Execution and Artistic scores. Reliability and strength of agreement of judging were high and very acceptable respectively. We suggest that judging reliability should be regularly examined to optimise technical and artistic criteria set by FIG for fairer competition.","PeriodicalId":49049,"journal":{"name":"International Journal of Performance Analysis in Sport","volume":"22 1","pages":"132 - 148"},"PeriodicalIF":2.1,"publicationDate":"2021-10-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"41539321","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 from the 2019 AFL (men’s) season and the 2017–19 AFLW (women’s) seasons, included the normalised (to 60 minute) match totals for 23 technical PIs and five score-based PIs. The values of 23 PIs were different (p < 0.05) between the women’s and men’s leagues. These differences suggest that women make fewer disposals (passes) to teammates, they make more errors and contest possession of the ball more often. Consequently, AFLW teams move the ball to within 50 metres of their goal and score less often. There are eight PIs that appear to be on a trend of increase in the AFLW. The relationships between the characteristics of team technical performance and match outcome are similar between the leagues, although contested possession is more important in the AFLW. Technical performance of the athletes in the women’s league is different to men, but some of these differences appear to be narrowing. Despite the differences, the relationship between technical performance and match outcome are similar in both leagues.","PeriodicalId":49049,"journal":{"name":"International Journal of Performance Analysis in Sport","volume":"22 1","pages":"29 - 37"},"PeriodicalIF":2.1,"publicationDate":"2021-10-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"41633717","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}

Overall, the referees had a decision-making accuracy of 88.2% with no changes over time (all p > 0.05). There were no significant associations between match demands, score difference, or field location and decision-making accuracy (all p > 0.05). However, significantly more incorrect decisions occurred when the referees were in a suboptimal position (29.0%) compared to an optimal position (10.9%) at the breakdown (p < 0.05). The findings suggest that referees’ decision-making accuracy during the breakdown remains relatively consistent across an elite rugby sevens tournament.

The aim of this study was to investigate whether there are differences in the gaze behaviour in two different groups of tennis players. Additionally, analysis between tennis serve returns of different quality have been conducted. Six-hundred and seventy-five returns performed by ten national and five international level tennis players were analysed. Focal visual attention was measured on-court using a mobile eye-movement tracking device. Fixations were mapped to different areas of interest relative to five consecutive service phases. Differences in the duration of visual fixations between different types of tennis returns were examined as well as correlations between most relevant areas of interest. Correlation analysis revealed differences in visual search strategies between both groups of tennis players. The international level group presented with gaze behaviour that indicates increased attention to specific visual information in tactically more successful serve returns. The national level tennis players on the other hand presented less specific gaze behaviour, and probably overall, less efficient attentional control. Additionally, international level tennis players presented return performance-specific gaze behaviour in the follow through-phase, which was not observed for the national level players.","PeriodicalId":49049,"journal":{"name":"International Journal of Performance Analysis in Sport","volume":"21 1","pages":"1149 - 1161"},"PeriodicalIF":2.1,"publicationDate":"2021-09-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"45757359","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 best predictive logistic model for match outcome was selected through all possible regression methods. The entire model included five categorical predictor variables (match location, team level, opponent level, scoring first, and match status at halftime) and one binary outcome variable (match outcome). The final model selected excluded the scoring first predictor and had a sensitivity and specificity greater than 80% for a cut-off point of .413. This model was applied to predict winning a match in 32 frequent situations determined from a two-step cluster analysis. The predictor with the highest contribution to the match outcome was match status at halftime, followed by the opponent’s level, team level, and match location.

Activity profile included rally duration (RD), resting time between points (RTP), resting time between games (RTG), resting time between sets (RTS), resting time (RT), effective playing time (EPT), total match time (TMT), work-to-rest ratio (W: R), shots per rally (SPR), shots per game (SPG), shots per set (SPS), shots per match (SPM), shot frequency (shots/second) (SPSc), and type of shots. Results showed that RTG and RT was longer at the Australian Open than at Roland Garros and Wimbledon, and the number of forehand (F) shots at Roland Garros was higher than at Wimbledon. The most common tennis shots are the F, the backhand (B), the first service and the volley (V), and more than 50% of the total shots in a match come from the baseline and mid court game. These results show that in women’s doubles the stimuli are short and intense and that net game is very important.","PeriodicalId":49049,"journal":{"name":"International Journal of Performance Analysis in Sport","volume":"21 1","pages":"1066 - 1080"},"PeriodicalIF":2.1,"publicationDate":"2021-09-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"43885995","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 purpose of this study was to develop feedback variants (FV) and investigate their effect on the athlete’s ability to keep the pace constant. Forty-eight participants completed four trials of a Conconi test (randomised) over four paces (7.5 − 10 km·h−1). A smartphone app provided athletes with four FVs: Classic, Sound (verbal), Vibration, and Sound & Vibration. We found a significant effect of FV on adherence (defined as time within 0.3 km·h−1 of target speed): F(3,141) = 41.45, p < .001, η2 = .268. Adherence in Classic (M± SD) 39.51 ± 13.51% was significantly lower (p < .001) than in Vibration (53.24 ± 14.98%), Sound (60.34 ± 11.21%) and Sound & Vibration (59.17 ± 15.17%). The novel FV provided better adherence compared to the conventional method, with Sound and Sound & Vibration showing the highest adherence. Generally, the novel FVs have the advantage of being easily implemented and decreasing the required time for setup, data collection and processing, therefore proving useful in conducting field performance tests.","PeriodicalId":49049,"journal":{"name":"International Journal of Performance Analysis in Sport","volume":"21 1","pages":"1015 - 1028"},"PeriodicalIF":2.1,"publicationDate":"2021-08-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"45743722","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}
