Global positioning system data were collected from 39 male soccer players across two seasons. Kinematic and mechanical MDP were identified by composite MDPk (maximal distance covered across moderate- and high-speed running and sprinting thresholds) and MDPm (maximal magnitude of high-intensity acceleration and deceleration efforts) criterion variables across 5 min moving average periods. Linear mixed models assessed the intensity, number of efforts, and duration of specific locomotor activities of each MDP by position. The kinematic MDP showed higher intensity, effort count, and relative duration of MDPk activities than mechanical MDP (p ≤ 0.001; ES: 0.7-1.7). Conversely, MDPm activities had greater magnitude, efforts, and relative duration in mechanical MDP (ES: 1.9-2.0). Similar constituent variable compositions were observed between peak periods. The MDPk comprised ~60 ± 16% moderate-speed running, ~30 ± 11% high-speed running, and ~14 ± 8% sprinting distances; MDPm included ~35 ± 23% and ~65 ± 23% high-intensity accelerations and decelerations. Positional differences revealed central defenders had lower, while full-backs and wide-midfielders had higher, MDP values. Findings from this study highlight the multidimensional characteristics of composite peak kinematic and mechanical periods in professional soccer. The differential contribution of low- and high-intensity locomotor activities during such periods, in terms of magnitude, number of efforts, and duration, should be considered by practitioners. Such insight can inform effective position-specific training prescription as well as bespoke recovery strategies based on the MDP observed during match play.","PeriodicalId":94191,"journal":{"name":"Research quarterly for exercise and sport","volume":" ","pages":"1-11"},"PeriodicalIF":0.0,"publicationDate":"2025-02-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143371414","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This study was conducted to determine the effect of whole-body vibration training with different vibration frequency on isokinetic trunk muscle strength, postural stability and jump performance in physically inactive and minimally active healthy female adults. Forty-five females were randomly assigned to 45 hz WBV group (n = 15), 25 hz WBV (n = 15) group and control exercise group without WBV (0 hz group, n = 15). Individuals in each group completed a 6-week trunk-based exercise program at the specified vibration frequency. Concentric and eccentric strength of trunk flexor and extensor muscles, postural stability and jump performance were assessed before and after the training period. There were significant group by time interactions in concentric and eccentric trunk muscle strength. Interaction effects showed no significant differences in postural stability and vertical jump performance. However, post hoc analyses revealed that all three groups significantly improved vertical jump height. These findings suggest that WBV combined with exercise training were effective to enhance the strength of trunk muscles in physically inactive and minimally active women.

Construct validity was assessed using 24 elite football players (12 elite seniors and 12 national juniors) with a comparison of mean test scores across different skill standards. The results demonstrated a significant difference between elite-senior and national-junior groups (p = <.001). Test-retest reliability was assessed with the national-junior group (n = 12) over two consecutive sessions. Mean scores demonstrated an ICC value of 0.95 (CI 0.85-0.98) and a CV of 4.9%. This study demonstrated a high level of construct validity by effectively distinguishing the kicking skill between elite-senior and elite-junior skill groups. The modified AFFB-DKA also possessed an acceptable level of reliability and thus provides coaches, recruitersand sport science staff with a measurement tool to effectively assess kicking skill performance in elite senior AF.","PeriodicalId":94191,"journal":{"name":"Research quarterly for exercise and sport","volume":" ","pages":"1-8"},"PeriodicalIF":0.0,"publicationDate":"2025-01-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143070601","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This idea means that, in sports like soccer, the playing area encapsulates an ecological niche, replete with affordances inviting collective and individual technical-tactical actions, contextualized with associated psychological and physical demands. To examine the co-adaptive relationships framing players' actions in their ecological niche, the present study employed a crossover design with repeated measures to compare the players' transactions within 11 vs. 11 training games across four different field dimensions (from official size to a small-sided game). Player transactions with the performance environment were analyzed across 40 game sequences, using 10Hz GPS positional data. Metrics such as convex hull dimensions, field occupancy, and proximity to opponents were derived. Repeated-measures ANOVA revealed significant differences between tendencies for forming synergies constrained by field dimensions scaling. When field size was reduced, the convex hull dimension significantly decreased. Additionally, relative field occupancy and distance to nearest opponent exhibited significant changes, especially when contrasted with performance transactions emerging on the official size field. These observations underline the essential functional relationship between the playing field dimension and emergent player actions. Such findings underscore the need for soccer coaches and training designers to integrate the specificity of field dimension scaling in training designs to represent competitive performance contexts. Data analytics deriving spatial constraint values from competitive matches may help researchers and practitioners improve task representativeness in practice and performance preparation, supporting the optimality of training niches in soccer.","PeriodicalId":94191,"journal":{"name":"Research quarterly for exercise and sport","volume":" ","pages":"1-12"},"PeriodicalIF":0.0,"publicationDate":"2024-12-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142869831","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Method: Shooting scores and EEG activity in the left and right temporal regions were collected from 20 healthy air pistol shooters (10 assigned to neurofeedback training) before and after a 16-session intervention completed within 6 weeks. Specifically, EEG low-alpha (8-10 hz), high-alpha (10-13 hz) power, and coherence obtained at the T3-Fz and T4-Fz recording sites over three consecutive 1-s intervals prior to trigger pull, were subjected to three separate 2 × 2 × 2 × 3 (Group x Hemisphere x Time x Epoch) ANOVAs. Results: The neurofeedback group exhibited elevated low- and high-alpha EEG power across both temporal regions, but no differences in EEG broad-band alpha coherence, accompanied by enhanced performance after the intervention compared to the control group.
