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. Nevertheless, WBV exercise training performed in this study had no significant impact on postural stability and jump performance.Clinical Trials Number: NCT05014958 (Pre-registired).","PeriodicalId":94191,"journal":{"name":"Research quarterly for exercise and sport","volume":" ","pages":"1-9"},"PeriodicalIF":0.0,"publicationDate":"2025-01-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143071317","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}

The purpose of this study is to overcome the test design issues currently present in elite senior testing protocols, within the applied setting, and assess the validity and reliability of a modified Level-3 Australian football field-based dynamic kicking assessment (AFFB-DKA) for senior elite AF players. 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.

Participants (N = 660; Girls = 310; Boys = 370; Mage = 64.07, SD = 9.12 months) included children enrolled in general (n = 627) or self-contained (n = 33) classrooms.

A higher score in perceived movement competence significantly lowered the odds of severe DD (t(654) = -3.24, p < 0.001, Wald = -6.49). A higher score in social skills significantly lowered the odds of severe DD (t(654) = -2.04, p = 0.04, Wald = -4.07). A higher score in problem behavior had a non-significant influence on severe DD (t(654) = -0.05, p = 0.96, Wald = -0.09). A higher score in attention significantly lowered severe DD (t(654) = -3.06, p = 0.002, Wald = -6.13). Those in a self-contained classroom had higher odds of severe DD (t(654) = 4.70, p < 0.0001, Wald = 9.39).

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. Conclusions: The findings support the influence of neurofeedback training on cerebral cortical arousal and performance of a precision-aiming task, however, the influence of the neurofeedback on brain dynamics (i.e. alpha power) extended beyond the targeted region as a nonspecific manifestation of cerebral cortical inhibition leading to neural efficiency at the homologous sites.","PeriodicalId":94191,"journal":{"name":"Research quarterly for exercise and sport","volume":" ","pages":"1-11"},"PeriodicalIF":0.0,"publicationDate":"2024-12-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142848739","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}

Methods: Mothers who were participants of the 2015 Pelotas (Brazil) Birth Cohort study were analyzed. Physical activity (PA) and sleep were measured using the nondominant wrist accelerometer model wGT3X-BT (ActiGraph, Pensacola, FL). Moderate-to-vigorous activities were measured in bouts of 5 minutes (MVPA 5-min bout). Activities were characterized as sustained and overall physical activity was expressed in mg, and MVPA (non-bouted) activities were characterized as not sustained. Sleep was presented as minute bouts, sleep time window, total sleep time, and sleep efficiency. Gestational weight gain (GWG) was calculated by a woman's weight at the end of gestation minus the pre-pregnancy weight. Linear regression models were used to evaluate the association between PA and GWG. Stratification by sleep characteristics in tertiles was performed. Results: The analytical sample included 1,938 women with information for PA, sleep, and GWG. The mean GWG was 12,030 g (SD = 6658.8).
