A total of 343 corner kicks from 56 matches were studied to examine the effective characteristics of corner kicks and strategies of strong and weak teams using associate rule analysis. In total, 17 goals were scored via corner kicks, accounting for 9.4% of the total goals (180) of the Women’s Super League in 2019. The result of associate rule analysis showed that the pattern of indirect, outside the box and eight attackers was more likely to create shots when a strong team (top 4 teams) faced a weak team (bottom 4 teams; Lift: 2.9). When a weak team faced a strong team, it was easier to create a shot by delivering the corner kick through an outswing ball directly to the near post (Lift: 6.091). These findings can help coaches to understand the key successful patterns of corner kicks in women’s football and choose a more effective attacking strategy of corner kicks according to the quality of both teams.","PeriodicalId":20674,"journal":{"name":"Proceedings of the Institution of Mechanical Engineers, Part P: Journal of Sports Engineering and Technology","volume":"27 1","pages":""},"PeriodicalIF":1.5,"publicationDate":"2024-08-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141946075","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The racing environment contributes critical cases. In Formula races, critical collisions occur during cornering. Drivers may not concentrate on the boundary regions at high speeds. For this reason, an AEB system may support the drivers in such cases. On the other hand, this system is not permitted to be implemented in racing cars. Therefore, an AEB system may be implemented into the environment of the track by using several Long-Range Radars (LRR) at critical points. The originality of this study is the approach in the implementation of an AEB system into the racing environment as a collision warning system. The effectiveness of the implementation of the AEB system into the racing environment depends on the reaction time of the racing drivers. A fuzzy logic controller was proposed to control Time to Collision (TTC) during cornering according to the track geometry. The controller design was established in MATLAB/Simulink interface with the simulations in the IPG/CarMaker environment. According to the simulation results, the approach in the implementation of the AEB system prevented a pile-up.","PeriodicalId":20674,"journal":{"name":"Proceedings of the Institution of Mechanical Engineers, Part P: Journal of Sports Engineering and Technology","volume":"20 1","pages":""},"PeriodicalIF":1.5,"publicationDate":"2024-07-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141871454","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Participants were allowed to select a bat length from within each type and weight according to their preference. The bats were then swung in random order. Reflective markers were placed on the bats and balls, allowing infrared cameras to track their motion from which speed was obtained. Given the differing ability of the participants, the study outcomes were normalized to the swing speed of each batter. Bat performance was quantified from the bat-ball coefficient of restitution. Laboratory measures of bat performance were shown to strongly correspond with the peak batting cage results. The ball exit speed of hollow bats exceeded that of traditional solid wood bats by as much as 5%. The ball exit speed was also found to be affected more by players’ ability than the bat type. Batter swing speed correlated strongly with bat inertia and was relatively insensitive to the bat-ball impact location, showing that participant effort was not biased by impact quality. Batter swing speed tended to depend more strongly on bat inertia than has been found in adult studies, which may be due to the smaller size of youth participants.","PeriodicalId":20674,"journal":{"name":"Proceedings of the Institution of Mechanical Engineers, Part P: Journal of Sports Engineering and Technology","volume":"46 1","pages":""},"PeriodicalIF":1.5,"publicationDate":"2024-07-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141871453","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The purpose of this study is to explore how varying frequencies of VAR interventions affect performance indicators in the CSL. VAR interventions were categorised into three groups, none (VAR0 = 198), one (VAR1 = 184) and two or more (VAR2 = 194). The performance variables included scoring-related variables (goals, shots, shots in the penalty area and penalties), attacking and passing-related variables (passes, crosses and free kicks) and defensive-related variables (tackles, fouls, yellow cards and red cards). The Kruskal-Wallis tests were used to examine the differences in performance variables among the different groups. The findings of these tests revealed that VAR was used in 66% of matches in the 2019–2021 season of the CSL. There were significant differences in penalties ( p < 0.01, η2 = 0.11), shots ( p < 0.05, η2 = 0.03), shots in the penalty area ( p < 0.01, η2 = 0.01), fouls ( p < 0.01,η2 = 0.02), passes ( p < 0.01,η2 = 0.05), free kicks (p < 0.05, η2 = 0.01) yellow cards ( p < 0.01, η2 = 0.02) and red cards ( p < 0.01, η2 = 0.05), but there were no significant differences in the number of goals ( p > 0.05), crosses ( p > 0.05) and tackles ( p > 0.05). Therefore, VAR intervention was frequently applied in the CSL during the 2019–2021 season, and the VAR interventions had various impacts on performance indicators.","PeriodicalId":20674,"journal":{"name":"Proceedings of the Institution of Mechanical Engineers, Part P: Journal of Sports Engineering and Technology","volume":"122 1","pages":""},"PeriodicalIF":1.5,"publicationDate":"2024-07-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141770244","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This versatility makes them highly applicable in both sports and rehabilitation settings. This study presents a novel framework based on a feedback control loop system, conceived to control a treadmill belt speed using a non-invasive and low-cost sensor (Microsoft Kinect) to detect the users’ position and avoid object obstruction issues. The speed of the treadmill belt is regulated according to the user’s speed, by means of a proportional-integrative-derivative (PID) controller and a parabolic gain function. By tuning the gain function parameters, the user can customize the response of the treadmill. Position data collected during exercise using the Microsoft Kinect sensor was compared with that collected with a stereophotogrammetric motion capture system, showing promising results in terms of accuracy in position assessment. The comparison highlighted a 0.9 degree of correlation between the two systems during the running and cross-country indoor skiing tests performed. In addition, upon considering the relationship between the differences and averages of the two measures, no systematic bias was identified. The system proved to be functional for running and cross-country skiing, and it can therefore re-create similar typical characteristics of outdoor environments (e.g., speed and slope) thanks to the non-invasive user’s position detection and the customizable gain function.","PeriodicalId":20674,"journal":{"name":"Proceedings of the Institution of Mechanical Engineers, Part P: Journal of Sports Engineering and Technology","volume":"13 1","pages":""},"PeriodicalIF":1.5,"publicationDate":"2024-07-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141770246","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Currently, the most widely utilized models are the Concept 2 (C2) and the Rowperfect 3 (RP3) static and dynamic ergometers. The timing and magnitude of acceleration during different phases of the rowing stroke have been shown to play a crucial role in performance. Current methods used to extract individual rowing strokes are difficult to apply and utilize complicated measurements, such as oar angle, filters, or machine learning. This paper compares the rowing acceleration profile across three rowing training devices. The C2 and RP3 ergometer handle and seat accelerations are compared to those of a single scull shell using a peak detection signal processing technique. This technique easily identifies peaks during a rowing session so that individual strokes can be extracted. Inertial measurement units (IMU) were attached to the oar handle and the ergometer seat/cage and the scull to measure the acceleration profile of individual strokes. The ergometer drag factor was adjusted to match the boat’s drag factor. One Division I male athlete rowed for 90 s, with 60 s of steady state rowing at 20 strokes/min (spm). The mean difference in acceleration between each ergometer and the boat was calculated. Findings suggest the RP3 ergometer acceleration profile more closely matches that of on-water rowing. Our analysis illuminates key differences between ergometers and on-water rowing, which can help rowers understand how their ergometer training translates to on-water rowing.","PeriodicalId":20674,"journal":{"name":"Proceedings of the Institution of Mechanical Engineers, Part P: Journal of Sports Engineering and Technology","volume":"26 1","pages":""},"PeriodicalIF":1.5,"publicationDate":"2024-07-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141770247","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This systematic review and meta-analysis sought to assess the impact of VAR on match performance in elite football competitions and determine its effects on diverse variables. We undertook a thorough search of electronic databases and conducted a meta-analysis using the statistical software R. The standardized mean difference (SMD) was employed to quantify the pooled effect of VAR on match performance variables, such as red cards, yellow cards, fouls, offsides, and playing times for both halves and the total game. The analysis included 12 studies, covering 10,088 matches from various elite football competitions. Homogeneity was found in the red cards group, whereas significant heterogeneity was noted in the other groups. VAR implementation correlated with a reduction in fouls (SMD = −0.187) and offsides (SMD = −0.216), indicating statistically significant decreases. Conversely, VAR led to an extension in match playing time, notably in first-half (SMD = 0.406), second-half (SMD = 0.517), and total playing time (SMD = 0.747), with all increases being statistically significant. Our findings indicate that VAR has a significant impact on match performance variables in elite football. Furthermore, the efficacy of VAR interventions differs among organizations and leagues, necessitating future research to ascertain whether VAR’s impact is universal or varies with specific competitions.","PeriodicalId":20674,"journal":{"name":"Proceedings of the Institution of Mechanical Engineers, Part P: Journal of Sports Engineering and Technology","volume":"43 1","pages":""},"PeriodicalIF":1.5,"publicationDate":"2024-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141193451","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
