“…Temporal trends in mean step test performance were analyzed from summary statistics at the sex-age group level for all Chinese adults (aged 20–59 years), and for separate location (rural and urban) and occupation (manual labor and non-manual labor) groups, using sample-weighted linear regression models relating the year of testing to mean step test performance. 31 Linear models were used because they naturally summarized the overall temporal trends. Because STI data are interval, we expressed the overall linear trends as standardized ES (i.e., the regression coefficient divided by the pooled SD), which facilitated comparisons between groups and with published studies.…”

“…Using procedures described elsewhere, 31 we calculated population-weighted mean changes (for 20-to 29-year-olds, 30-to 39-year-olds, 40-to 49-year-olds and 50-to 59-year-olds, plus young adults (20-to 39-year-olds), middle-aged adults (40-to 59-year-olds), and all adults), sex (men and women), location, and occupation groups by pooling the rates of change across all relevant groups using post-stratification population weighting. 33 Population weights were obtained from sex-age-specific population estimates for China in 2000 using United Nations data.…”

Backgroud/Objective Cardiorespiratory endurance is an excellent marker of functional endurance and health among adults. The aim of this study was to estimate temporal trends in step test performance for Chinese adults between 2000 and 2014. Methods Apparently healthy adults aged 20–59 years were included. Nationally representative step test data ( n = 603,977) from 2000, 2005, 2010, and 2014 were reported descriptively by the China Physical Fitness Surveillance Center. Temporal trends in means were estimated at the sex-age level for all adults and separate location/occupation groups using sample-weighted linear regression, with trends in distributional characteristics described visually and estimated as the ratio of coefficients of variation (CVs). Results Collectively, there was a negligible improvement in mean step test performance of 0.12 standardized effect sizes (95% confidence interval (95%CI): 0.11–0.13). Negligible to small improvements were observed for all age, sex, location, and occupation groups. Variability declined substantially over time (ratio of CVs (95%CI): 0.86 (0.86–0.86)), with negligible to large improvements in those below the 10th percentile, and negligible to moderate declines in those above the 90th percentile. Conclusion There have been negligible to large improvements in step test performance for low to average performing Chinese adults since 2000, which may be meaningful to public health because low endurance is an important risk factor for all-cause mortality.

“…The American norms, while most recent from within the country, were somewhat antiquated. Caution should be exercised concerning such percentile ranks given that it has been suggested that high- and upper-middle-income countries may have been experiencing secular declines in SLJ performance in youth without VI since the year 2000 [ 36 ]. Likewise, the European norms were not directly translatable to the current American sample.…”

Muscular fitness, an important marker of health in youth, includes explosive strength, which can be assessed using the standing long jump (SLJ). Little is known concerning the SLJ in populations with disabilities such as youth with visual impairments (VI) who trend with decreased health- and performance-related outcomes. The purposes of this study were to investigate multidimensional SLJ performance outcomes in youth with VI (i.e., descriptives and percentages of occurrence) and to explore associations among such variables and known factors of interest (e.g., age) using robust linear bivariate regressions. This study was a secondary analysis from data collected in 2018 (N = 61, Mage = 12.98 years, SD = 2.21). SLJ performance was investigated using a multidimensional focus (e.g., distance, Test of Gross Motor Development-3 horizontal jump, landing developmental sequences, landing joint displacement, and stabilization after landing). In general, SLJ performance was substandard in youth with VI. Most SLJ assessment scores were predictive of other SLJ assessment scores. Few hypothesized variables of interest (e.g., multimorbidity) were predictive of SLJ performance. Youth with VI who match the characteristics of the current sample may have decreased explosive strength/muscular fitness and, worryingly, their SLJ performance may not be influenced by expected factors (e.g., age). Implications and explanations for these results are discussed.

“…5 Internationally, there are numerous tests and test batteries used to assess PF levels in children and adolescents, 13 enabling decisionmakers to monitor population health. In this way, various instruments have been developed in different parts of the world in order to report or track population levels of PF, especially for children and adolescents, [14][15][16][17] because schools provide opportunities for population-based testing that do not normally exist for adults. Systematic reviews and metaanalyses have identified and gathered the results of published studies related to PF, which have allowed global comparisons,…”

IntroductionPhysical fitness (PF) is an important indicator of health in children and adolescents. Internationally, test batteries have been used to assess overall PF. In Latin America, however, while PF has been widely measured, there is no accepted test battery, making it difficult to monitor and/or compare the PF levels of Latin children. The aim of this study, therefore, is to systematically review and potentially meta-analyse the peer-reviewed literature regarding the assessment of PF in Latin American children and adolescents.Methods and analysisThis systematic review and meta-analysis will follow the Preferred Reporting Items for Systematic Reviews and Meta-Analyses Protocols statement. The systematic literature search will be performed in MEDLINE, Scopus, SciELO, EMBASE, Cochrane Library, Web of Science, SPORTDiscus, LILACS and Latindex (Spanish) to locate articles published up to April 2021. Eligible studies will include both descriptive and analytic study designs. Meta-analyses are planned for sufficiently homogeneous PF outcomes with regard to statistical and methodological characteristics. Narrative syntheses are planned for PF outcomes that are considered to be too heterogeneous. The statistical program STATA V.15 will be used for meta-analyses, with subgroup analyses performed according to the characteristics of included studies.Ethics and disseminationThis systematic review and meta-analysis protocol is designed to provide updated evidence on the PF of Latin American children and adolescents. Findings from this review may be useful for teachers, researchers and other professionals responsible for paediatric fitness and health promotion/surveillance. The results will be disseminated through peer-reviewed scientific publications, conferences, educational talks and infographics.PROSPERO registration numberCRD42020189892.
