Abstract
.Peak oxygen uptake (V O_2) is internationally recognized as the criterion measure of youth aerobic fitness, but flawed laboratory assessments and fallacious interpretations of peak V O_2 in ratio with body mass have confused our understanding of the development of aerobic fitness. Moreover, the recent emergence of specious predictions of peak V O_2 from performance tests and the promotion of spurious ‘clinical red flags’ and cardiometabolic cut-points have confused our understanding of the relationship between youth aerobic fitness and health. Recent longitudinal studies of 10-18 year-olds using multilevel allometric modelling have empirically demonstrated that peak V O_2 increases in accord with sex-specific, concurrent changes in age- and maturity status-driven morphological covariates with the timing and tempo of changes specific to individuals. During both cycle ergometry and treadmill running age- and maturity-status- driven changes in fat free mass have been revealed as the most powerful morphological influences on the development of youth aerobic fitness. To bring some clarity to current confusion, this paper argues that future studies must be founded on rigorous assessment and interpretation of peak V O_2 and ensure that they address the development of youth aerobic fitness and its relationship with present and future health in relation to appropriate sex-specific morphological covariates governed by individual biological clocks.

Recent publications in the British Journal of Sports Medicine ( BJSM) (mis)represent and (mis)interpret young people’s cardiorespiratory fitness (CRF) and potentially (mis)inform health promotion and clinical practice. 1 2 The papers recognise peak VO2as the criterion measure of CRF but base their estimations of peak VO2 on performances in 20 m shuttle runs (20mSRT). Moreover, and of serious concern to us, estimated peak VO2 is (mis)represented and (mis)interpreted in ratio with body mass (ie, i...

Abstract Objectives Reference values are necessary for classifying children, for health screening, and for early prevention as many non-communicable diseases aggravate during growth and development. While physical fitness reference standards are available in children aged 6 and older, such information is lacking in preschool children. Therefore, the purposes of this study were (1) to provide sex-and age-specific physical fitness reference standards for Spanish preschool children; and (2) to stud...

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 ...

Purposes To investigate the development of peak oxygen uptake (\(\dot{{V}}{\text{O}}_{2}\)) assessed on both a treadmill and a cycle ergometer in relation with sex and concurrent changes in age, body mass, fat-free mass (FFM), and maturity status and to evaluate currently proposed ‘clinical red flags’ or health-related cut-points for peak \(\dot{{V}}{\text{O}}_{2}\).

The aim was to examine the bidirectional association between cardiorespiratory fitness (CRF) and fatness in a 2-year longitudinal study conducted in young people. A total of 1082 children (512 females) and 727 adolescents (342 females) with complete data at baseline and follow-up were included. CRF was determined by the 20-m shuttle run test. Height and weight were measured and body mass index and fat mass index (kg/m(2) ) were calculated. Triceps and subscapular skinfolds were assessed to compu...

BACKGROUND: The Cooper Test, is a field test, simple and useful in the school context. The aim of this research was the definition of the trend in Cooper endurance test along with the growth. In particular, through the scaling method (allometric). METHODS: A total of 556 of European sedentary children aged 11-13 years (282 boys; 274 girls) were involved. All subjects were evaluated through the Endurance Cooper test (12 min run test). To identify the most appropriate body size and shape character...
