The objective of this study was to establish cut-points to help identify potential clustered cardiometabolic risk among children (9–13 years) and youth (14–17 years) using the modified Canadian Aer...

To estimate national and international temporal trends in handgrip strength for children and adolescents, and to examine relationships between trends in handgrip strength and trends in health-related and sociodemographic indicators. Data were obtained through a systematic search of studies reporting temporal trends in the handgrip strength for apparently healthy 9–17-year-olds, and by examining large national fitness datasets. Temporal trends at the country–sex–age level were estimated by sample...

In their editorial, Armstrong and Welsman1 suggest that the 20 m shuttle run test (20mSRT) (mis)represents and (mis)interprets youth cardiorespiratory fitness (CRF), and potentially (mis)informs health promotion and clinical practice. Their main arguments are: (a) the 20mSRT only provides an estimate of CRF (ie, peak ![Formula][1] O2) and (b) estimates are ratio-scaled (ie, expressed relative to body mass). In this response we provide several reasons, rooted in evidence, which refute their inter...

Purpose To identify criterion-referenced standards for cardiorespiratory fitness (CRF); to estimate the percentage of children and youth that met each standard; and to discuss strategies to help improve the utility of criterion-referenced standards for population health research. Methods A search of four databases was undertaken to identify papers that reported criterion-referenced CRF standards for children and youth generated using the receiver operating characteristic curve technique. A pseud...

Objective To estimate international and national temporal trends in the cardiorespiratory fitness (CRF) of children and adolescents and to examine relationships between temporal trends in CRF and temporal trends in broad socioeconomic and health-related indicators across countries. Methods Data were obtained from a systematic search of studies that explicitly reported 20 m shuttle run test (a validated measure of CRF) descriptive data on apparently healthy individuals aged 9–17 years. Following ...
