They were randomly assigned to a gait training program or a control group. Both groups received neurodevelopmental treatment over a 12-week period. In addition, the intervention group received treadmill training combined with balance exercises. Walking speed, Gross Motor Function Measure dimension D and E, Pediatric Balance Scale, 1-minute walk test, and ankle range of motion were measured at baseline and at 12 weeks by a blind assessor. Data were analyzed with 2-way analysis of variance with 1 repeated factor (time) and 1 independent factor (group).Results: The intervention group improved walking speed (10-m walk) by a mean of 7.4 units (95% CI, 1.6-16.4) and the Gross Motor Function Measure-E score by a mean of 16.8 units (95% CI, 3.9-29.7) compared with the control group. No other significant between-group differences were observed. Within-group statistically significant differences were observed primarily for the gait training group. No serious adverse events were reported.Conclusion: A gait training program appeared to be beneficial for mobility-related outcomes in young children with cerebral palsy. Training focused on gait, and this was increased with less, if any, change in other outcomes, such as balance or range of motion.","PeriodicalId":49712,"journal":{"name":"Pediatric Exercise Science","volume":" ","pages":"1-6"},"PeriodicalIF":1.3,"publicationDate":"2025-09-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145139281","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 study was approved by the ethics committee of the University of Murcia (2828/2020). A quasi-experimental A-B study was designed, where A was a tournament with the FEB regulation and B a tournament with the modified regulation. The dependent variables analyzed were the time players spent in different heart rate zones and heart rate variability. Maturity stage was considered a moderating factor in the intervention effect.Results: The results show significant differences in time in zone 4, reduced time in zone 5, maximum heart rate, and square root of the mean value of the sum of the squared differences. Maturity stage conditioned the intervention effect for square root of the mean value of the sum of the squared differences when players had a percentage of predicted adult height higher than 89.92%.Conclusion: From a cardio protective perspective, it has been found that U-13 players spend more time in zones considered cardio protective during the modified tournament. In addition, the modification reduces the differences in terms of fatigue between early and late developing players.","PeriodicalId":49712,"journal":{"name":"Pediatric Exercise Science","volume":" ","pages":"1-8"},"PeriodicalIF":1.3,"publicationDate":"2025-09-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145042093","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}

Therapeutic exercise is essential to counteract physical impairments, which requires the implementation of outcome measures (OMs) in research and practice as they provide meaningful results for research efficacy, exercise program evaluation and quality, medication tolerance, and patient improvement.Purpose: To assess the types of OMs implemented in exercise randomized controlled trials related to the juvenile idiopathic arthritis cohort and the psychometric properties and age appropriateness of the implemented OMs.Methods: The review was registered with PROSPERO (CRD42022336345) on May 30, 2022, followed by a systematic search across PubMed, EBSCOhost, Web of Science, and Ovid. Studies included were appraised using the Joanna Briggs Critical Appraisal Tool for randomized controlled trials. All data collection occurred according to the Preferred Reporting Items for Systematic Reviews and Meta-analysis.Results: A total of 51 outcome measures were implemented across the 20 randomized controlled trials: 2 clinician-reported OMs (4%), 19 patient or parent-reported OMs (37%), and 30 physical performance OMs (59%). The vast majority of included OMs increase the difficulty of comparison across studies and indicate a lack of consideration for validity, reliability, and age appropriateness.","PeriodicalId":49712,"journal":{"name":"Pediatric Exercise Science","volume":" ","pages":"1-8"},"PeriodicalIF":1.3,"publicationDate":"2025-09-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145034550","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}

Their perceptual-cognitive skills were evaluated using a 3D multiple-object tracking task (ie, the NeuroTracker [NT]) with (3D) and without (2D) stereopsis.Results: In moderately trained children, NT scores progressively decreased from BQ1 to BQ4, with a significant difference between the first 3 birth quartiles and BQ4 (P < .01), independent of stereopsis. In well-trained children, however, no significant differences were detected in NT scores between quartiles, and well-trained children in BQ4 exhibited NT scores comparable to moderately trained children in the first 3 quartiles.Conclusion: RAE showed a significant disadvantage on the perceptual-cognitive scores in moderately trained children born in BQ4. However, well-trained children born in BQ4 performed similarly to other well-trained children and to moderately trained children born in the first 3 birth quartiles, meaning that training background may offset the disadvantage associated with RAE from childhood into adolescence.","PeriodicalId":49712,"journal":{"name":"Pediatric Exercise Science","volume":" ","pages":"1-7"},"PeriodicalIF":1.3,"publicationDate":"2025-08-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144849480","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}

Zero-inflated Gamma and Logistic Mixed models were applied to compare, respectively, LTPA and active commuting between survey years.Results: Cross-sectional analyses showed that the odds of engaging in any type of LTPA were similar between waves.
