Recent reports suggest scores in reading and mathematics have also declined. Virtual reality (VR) is a technology that can be used to simulate real-world scenarios, like classroom learning. This study investigated whether a single dose of walking benefits learning in a VR classroom (measured via quiz performance).Method: Forty-seven children (15 females, 9.64 [0.12] y) completed 2, randomized and counterbalanced 20-minute interventions on separate days: acute PA (walking) and seated rest (control), followed by a stationary educational lesson in a distracting VR classroom. Children then completed a quiz on the lesson.Results: Children had higher quiz performance following PA (z-score = 0.16 [0.13]) compared with following rest (z-score = -0.18 (0.14); F1,45 = 6.17, P = .017), indicating that PA enhanced learning. Children with average intelligence quotient had quiz performance that was higher after PA (z-score = 0.04 [0.20]) compared with after rest (z-score = -0.60 [0.19]), t(22) = 3.34, P = .003. Higher intelligence quotient children did not demonstrate differences in quiz performance after PA compared with after rest.Conclusions: Learning in a VR classroom may be improved following acute PA, particularly for children with average intelligence quotient. These findings support public health guidelines promoting PA across the day.","PeriodicalId":49712,"journal":{"name":"Pediatric Exercise Science","volume":null,"pages":null},"PeriodicalIF":1.4,"publicationDate":"2024-10-09","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142394733","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}

We tested the hypothesis that measuring metabolic data with the EIB protocol (EIB-CPET) would yield greater diagnostic information than the EIB protocol.Methods: Exercise test diagnosis for healthy children with DOE referred to the pulmonary exercise lab from January 2011 through July 2023 were retrospectively compared between those performing either the EIB or EIB-CPET protocols.Results: One hundred and twenty-seven patients with unexplained DOE were analyzed. Of the 72 patients tested on the EIB protocol, 49% had stridor and 5% with EIB.

GMC was assessed with the KörperkoordinationsTest für Kinder. Physical fitness was assessed with handgrip strength, standing long jump, and shuttle-run test. Height and weight were measured with standardized protocols. Analysis of variance, covariance, and logistic regression were used.Results: A negative secular trend in GMC (based on raw scores) for boys and girls aged 6-8 years was observed. However, a positive trend was observed at 11 years of age but only in boys. Finally, there were no significant changes in the likelihood of children having below-normal GMC from 2009 to 2019.Conclusions: Secular trends in GMC were negative in Peruvian children, especially at 6-8 years of age.

Statistical analyses included multiple linear regression and command margins.Results: Significant associations were found between systolic BP (SBP) and time spent in LPA (B = -0.08; 95% CI, -0.15 to -0.01) and SB (B = 0.071; 95% CI, 0.004-0.138), albeit only in boys. Furthermore, an interaction was observed between time spent in SB and MVPA for SBP in boys (B = -0.002; 95% CI, -0.004 to -0.0008). The main interaction effect of increasing SBP was a combination of <75 minutes per day of MVPA and up to 600 minutes per day of SB.Conclusions: Increased time in LPA and reduced time spent in SB during the day are associated with lower SBP in male adolescents. Additionally, the relation between SB and SBP was attenuated by MVPA.

There are far fewer investigations on cross-education effects on contralateral heterologous (different) muscles and age (youth vs adult) and no studies investigating sex differences. Hence, the objective was to compare cross-education in female and male youth and young adults to contralateral homologous (chest press [CP], elbow flexors and extensors, handgrip isometric strength, and shot put) and heterologous (leg press, knee extension isometric strength, and countermovement jump) muscles. Twenty-eight female adults, 28 female youth, 28 male adults, and 28 male youth (total: 112) were examined before and after an 8-week (3 sessions/wk) unilateral, dominant arm, CP training program. Unilateral testing assessed dominant and nondominant leg press and CP 1-repetition maximum, knee extensors, elbow extensors, elbow flexors, and handgrip maximum voluntary isometric contraction (MVIC) strength, as well as shot put distance and countermovement jump height. Unilateral CP training induced training specific (CP 1-repetition maximum) and nonspecific (elbow extensors, elbow flexors, handgrip MVIC force, and shot put distance) improvements (P < .04, η2: .45-.85) but no significant lower body improvements. There was evidence for testing limb specificity as the dominant arm provided significantly (P < .021, η2: .17-.75) greater training gains than the nondominant arm. Youth's training adaptations exceeded with unilateral CP 1-repetition maximum, elbow extensors MVIC force, and shot put distance (P < .049, η2: .14-.49). No sex main effect differences were apparent.

Collected data included anthropometric measures, physical activity, screen time, and spirometric measures expressed as percent predicted values. Data were analyzed using multiple linear regression and 2-way analysis of variance.RESULTSThere were positive associations between physical activity and forced vital capacity (β = 3.897, P = .001) and forced expiratory volume in the first second (β = 2.931, P = .021).
