The GAC-PAQ is designed to assess physical activity (PA) across all key domains (i.e., school, chores, work/volunteering, transport, free time, outdoor time). It aims to address multiple gaps in global PA surveillance (e.g., omission of important PA domains, insufficient cultural adaptation, underrepresentation of rural areas in questionnaire validation studies).The purpose of this study was to assess the content validity of the GAC-PAQ among PA experts, 8- to 17-year-olds, and one of their parents/guardians, and to discuss changes made to the questionnaire based on participants' feedback.METHODSSixty-two experts in PA measurement and/or surveillance from 24 countries completed an online survey that included both closed- and open-ended questions about the content validity of the GAC-PAQ. The proportion of experts who agreed or strongly agreed with the items was calculated. Child-parent/guardian dyads from 15 countries (n = 250; 10-40 per country) participated in a structured cognitive interview to assess the clarity of the questions and response options, and they were encouraged to provide suggestions to improve clarity and facilitate completion of the questionnaire. Participating countries are: Aotearoa New Zealand, Brazil, Canada, China, Colombia, Czech Republic, India, Malawi, Mexico, Nepal, Nigeria, Spain, Sweden, Thailand, and the United Arab Emirates. Interviews were conducted in 13 different languages and structured by PA domain. Generic images were included to help participants in answering questions about PA intensity.RESULTSExpert agreement with the items for each domain exceeded 75%, and their qualitative feedback was used to revise the questionnaire before cognitive interviews. In general, participants found the questionnaire to be comprehensive. Adolescents (12-17 years) found it easier than children (8-11 years) to answer the questions. Several children struggled to answer questions about the duration and intensity of activities and/or concepts related to travel modes, active trips, and organized activities. Many parents/guardians were unsure about the frequency, duration, and intensity of their children's or adolescents' PA at school and/or recommended using more culturally relevant and appropriate images. Some participants misunderstood the concept of activities that \"make you stronger\" (intended to assess resistance activities) and/or struggled to differentiate between work, volunteering, and chores.CONCLUSIONParticipants' feedback was used to develop a revised, simplified, and culturally adapted GAC-PAQ, which will be pilot-tested in all 15 countries in an App that will include country-specific images and narration in local languages. Further research is needed to assess the reliability and validity of the revised GAC-PAQ.","PeriodicalId":48897,"journal":{"name":"Journal of Sport and Health Science","volume":"42 1","pages":"101074"},"PeriodicalIF":11.7,"publicationDate":"2025-07-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144578577","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

{"title":"Triggering sarcomerogenesis: Examining key stimuli and the role attributed to eccentric training -Historical, systematic, and meta-analytic review.","authors":"Anthony J Blazevich,Walter Herzog,João Pedro Nunes","doi":"10.1016/j.jshs.2025.101073","DOIUrl":"https://doi.org/10.1016/j.jshs.2025.101073","url":null,"abstract":"BACKGROUNDSerial sarcomere number (SSN) critically influences muscle function and is hypothesized to protect against injury. While most evidence for SSN addition comes from non-human animal studies, eccentric exercise is often proposed as a key stimulus due to its association with increased fascicle length in humans. However, the most efficient exercise stimuli and the effectiveness of eccentric training in increasing SSN remain unclear. The objective of this study was to provide a detailed historical overview of research exploring the mechanical factors regulating muscle/fiber length and its relationship with function, and to explore more recent evidence that eccentric muscle contractions might be an important stimulus for SSN regulation using a meta-analytic approach.METHODSAn extensive literature search with snowballing was conducted to build the historical review. A systematic review with random-effect meta analyses was performed to compare proposed types of fiber-lengthening exercises to control conditions.RESULTSThe historical review demonstrated that the application of forces at long fiber lengths, but not specifically the use of greater excursions, plays an important role in increasing SSN. Animal data showed changes in SSN exceeding 20% over several weeks with varied forms of activities. Nonetheless, the meta-analysis revealed a lack of effect of eccentric resistance training in animal models (Δ = 1%; Cohen's d = 0.19 (-0.29, 0.67), p = 0.449).CONCLUSIONHigh active or passive muscle forces applied at long fiber lengths appear to be the key stimuli triggering sarcomerogenesis. Eccentric exercise does not seem to be a key promoter of SSN. Too few studies exist to draw conclusions as to the effect of eccentric exercise on SSN in humans. Understanding the mechanical triggers and physiological mechanisms involved in serial sarcomere addition could help in the development of exercise (and other) interventions to optimize muscle function and reduce injury risk.","PeriodicalId":48897,"journal":{"name":"Journal of Sport and Health Science","volume":"9 1","pages":"101073"},"PeriodicalIF":11.7,"publicationDate":"2025-07-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144578578","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
