To investigate longitudinally (1) the contribution of morphological covariates to explaining the development of maximum cardiac output (${\dot{\text{Q}}} max) and maximum arteriovenous oxygen difference (a-vO2 diff max), (2) sex differences in {\dot{\text{Q}}} max and a-vO2 diff max once age, maturity status, and morphological covariates have been controlled for, and, (3) the contribution of concurrent changes in morphological and cardiovascular covariates to explaining the sex-specific d...

Current evidence of metabolic health benefits of high-intensity interval training (HIIT) are limited to longer training periods or conducted in overweight youth. This study assessed 1) fasting and postprandial insulin and glucose before and after 2 weeks of HIIT in healthy adolescent boys, and 2) the relationship between pre intervention health outcomes and the effects of the HIIT intervention. Seven healthy boys (age:14.3 ± 0.3 y, BMI: 21.6 ± 2.6, 3 participants classified as overweight) comple...

Rigorously determined peak oxygen uptake is internationally recognized as the criterion measure of youth cardiorespiratory fitness. The assessment and interpretation of children’s and adolescents’ peak oxygen uptake and the relationship of the measure with other health-related variables are well documented. There has been a recent resurgence of interest in the prediction of peak oxygen uptake from field performance tests in young people. However, coupled with ratio-scaling of data and the raisin...

Objectives Over 30 years ago we demonstrated the poor criterion validity of a popular fitness test, the 20 m shuttle run or ‘bleep’ test (20mSRT). We discounted the test and assumed that others with demonstrable validity and reliability would replace its use in research. Around then, our attention was drawn to an eloquent but obscure paper by JM Tanner (1949) which detailed the fallacy of simple division by body mass to accommodate body size differences in physiological function. Tanner describe...

Purpose To investigate (1) whether maximal stroke volume (SVmax) occurs at submaximal exercise intensities, (2) sex differences in SVmax once fat-free mass (FFM) has been controlled for, and, (3) the contribution of concurrent changes in FFM and SVmax to the sex-specific development of peak oxygen uptake \( \left( {{\dot{\text{V}}\text{O}}_{2} } \right) \).

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...
