The objectives of the study were to determine the temporal structure of combat of judo in men and women with VI and establish differences between sexes, within their respective weight categories and between the different minutes of combat. The sample was formed by all the judokas with VI who participated in the 2018 IBSA Judo World Championship (172 men and 95 women). Through observational methodology, we analysed all the combats (n = 365). In order to obtain the results, we used different analytical techniques: descriptive, one-way ANOVA, t-test to show independents, chi-square, effect size and T-Patterns analysis. The level of significance was ρ ≤ .05. The results define a temporal structure by sex and by weight category that allows the judo professionals to plan precise and adequate trainings for the athletes. We conclude that there are differences in the temporal structure of judo combat within the men and women with VI, within their respective weight categories and within the different minutes of combat. The temporal structure of combat has changed more markedly in women and unevenly in the different weight categories for both sexes.","PeriodicalId":49049,"journal":{"name":"International Journal of Performance Analysis in Sport","volume":"22 1","pages":"225 - 249"},"PeriodicalIF":2.1,"publicationDate":"2022-02-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"48257728","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}

Fifteen Taekwondo experts performed four different type of roundhouse kicks at three different stepping-in-place tempos (120, 140, and 160 bpm) in two stimulus speeds conditions for CAT performance. Raw scores were transformed to three error scores; constant, absolute, and variable errors and were analysed using separate 2 (stimulus speeds) x 4 (kick types) x 3 (tempos) repeated measures of analyses of variance. In the results, error scores (CE and AE) were significantly lower at 140 and 160 bpm compared to that at 120 bpm. Significant differences according to stepping-in-place tempo were also evident in the type of kicks (front leg < rear leg and body < head). The error scores were found to increase as the stimulus speed increased (10 mph < 20 mph) and were lower at 140 bpm compared to 120 and 160 bpm at both stimulus speed.

This study examined the CoD demands of Gaelic football via a time-motion analysis of senior inter-county match play. The Bloomfield movement classification (BMC) was adapted for application to Gaelic football. A new “descriptor” was used in an effort to account for the decision-making component of agility by isolating actions that occurred during active engagement with play. Of 1,899 changes of direction (CoDs) identified, 1,035 occurred during active engagement in play. The left/right split for CoDs during active engagement in play was 47.1/49.9%, indicating no preference for completing actions to one side over the other. Whilst the most common CoDs were ≤90° (74.9%), 80% of CoDs greater than 270° took place during active engagement in play. CoD actions are very common in Gaelic football and may be more common than in other field and court sports. It is important that athletes are physically prepared to cope with the demands of very acute CoDs during meaningful periods of match play.","PeriodicalId":49049,"journal":{"name":"International Journal of Performance Analysis in Sport","volume":"22 1","pages":"195 - 208"},"PeriodicalIF":2.1,"publicationDate":"2022-02-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"45980833","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}

Eleven referees underwent anthropometric and fitness assessments (40-m sprint, Yo-Yo Intermittent Recovery Test, 1.2-km shuttle run) prior to the 2019 Rugby World Cup. Match activities were assessed via global positioning system devices (total distance, high-speed running distance [>5 m·s−1], average speed, and peak intensities over 1-min, 5-min, and 10-min epochs) and heart rate variables were measured using chest-worn monitors (HRmean, summated-heart-rate-zones, time above 90% HRmax). Forty-metre sprint time was significantly related to maximum speed (P = 0.004; r = −0.79) and high-speed running distance (P = 0.037, r = −0.63) during matches. Likewise, ∑7 skinfold thickness was significantly correlated with high-speed running distance (P = 0.01, r = −0.72). Yo-Yo Intermittent Recovery Test, 1.2-km Shuttle Run Test, age, and body mass index exhibited non-significant correlations (P > 0.05, r = −0.58 to 0.53) with match demand variables. Results suggest it may be pertinent for referees to optimise sprint capacity and body fat composition to execute greater high-speed running volumes and reach higher peak speeds during matches. Yo-Yo Intermittent Recovery Test and 1.2-km shuttle run tests are not correlated to specific match activity variables and thus may not be relevant for monitoring of rugby union referees.","PeriodicalId":49049,"journal":{"name":"International Journal of Performance Analysis in Sport","volume":"22 1","pages":"183 - 194"},"PeriodicalIF":2.1,"publicationDate":"2022-01-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"48885451","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}

Jonckheete-Terpstra and Kruskal Wallis nonparametric tests were used to compare the IPA according to variations in players’ age, numerical relations and pitch zones considered for analysis. All ages and numerical relation results revealed the highest IPA in the zones closer to the goal and were lower in the middle of the pitch. For 3 × 3 to 10 × 10 numerical relations, the IPA was higher in the U15 and lower in the U17. The greater differences between the age groups concerned numerical relations of 6 × 6 to 10 × 10 (p ≤ 0.001). The effect size was moderate between the U15 and U17 in numerical relations of 8 × 8 to 10 × 10.

Ten advanced and ten intermediate players performed both voluntary isokinetic contraction test and forehand topspin strokes with maximum-effort towards cross-court target zone. The results indicated that advanced players generated significantly greater maximum racket speeds during forward swing phase (P < 0.05). At the instant of the topspin stroke, significantly smaller shoulder horizontal flexion and elbow flexion angles, but larger joint angular velocities in advanced players (P < 0.05). Moreover, advanced players exhibited longer muscle firing duration of anterior deltoid and biceps brachii as well as higher root mean squares and EMG integrals of the abdominal external oblique, anterior deltoid and biceps brachii muscles than the intermediate players (P < 0.05). Furthermore, the isokinetic results showed higher shoulder abduction/adduction, hip flexion/extension and knee flexion torques at fast speed (240°/s) and higher elbow flexion torque at medium speed (120°/s) in advanced players (P < 0.05). The findings suggest that higher activation of the deltoid, biceps and abdominal external oblique muscles as well as larger muscle strength under higher speed conditions would be the plausible key factors to maximise racket and joint angular velocities in forehand topspin.","PeriodicalId":49049,"journal":{"name":"International Journal of Performance Analysis in Sport","volume":"22 1","pages":"16 - 28"},"PeriodicalIF":2.1,"publicationDate":"2022-01-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"41669429","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}

Ladies Gaelic football (LGF) is the most popular female sport in Ireland with over 200,000 members, however there has been no research to benchmark performance. The current study investigates the game characteristics of LGF by developing analysis system which could provide benchmark profiles of successful performance at elite level and evaluate the transferability of the game intelligence available within LGF’s brother sport, Gaelic football (GF). Thirty-one games (62 performances) were analysed from the 2019 and 2020 TG4 All-Ireland Senior Ladies Football Championship using NacSport Scout+. Statistical differences between winning and losing performances were identified using paired sample t-tests (p ≤ 0.05) and Wilcoxon signed ranked tests (p ≤ 0.05). Winning teams were found to be significantly superior to losing teams, demonstrating superior ability to gain and use possession. LGF and men’s GF teams adopt different strategic approaches to the game. The current study provides a first insight into the nature of LGF with benchmark data, facilitating a better understanding of the game demands of LGF and the key points of difference between male and LGF.","PeriodicalId":49049,"journal":{"name":"International Journal of Performance Analysis in Sport","volume":"22 1","pages":"51 - 65"},"PeriodicalIF":2.1,"publicationDate":"2021-12-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"42118391","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}
