Abstract
ABSTRACTThis paper examined the influence of different statistical modeling techniques on the interpretation of peak ˙VO2 data in groups of prepubertal, circumpubertal, and adult males (group 1M, N = 29; group 2M, N = 26; group 3M, N = 8) and females (group 1F,N = 33; group 2F, N = 34; group 3F, N =

Peak O2 uptake (VO2) has traditionally been compared among individuals differing in body composition by dividing measured values (1/min) by fat-free mass (FFM) (i.e., ratio method). However, the ab...

In his “Editor’s Notes,” Rowland (15) raised an issue that is fundamentally important but frequently appears to be misunderstood. The issue is scaling, that is, the means of partitioning out differences in size. Because physiological variables are often dependent on size, an adjustment has to be made to “normalize” for body dimensions and assess more precisely a particular characteristic. These adjustments have four main applications: (a) to an individual who is compared against standards for th...

To investigate the effect of endurance training on physiological characteristics during circumpubertal growth, eight young runners (mean starting age 12 years) were studied every 6 months for 8 years. Four other boys served as untrained controls. Oxygen uptake (\(\dot V\)O2) and blood lactate concentrations were measured during submaximal and maximal treadmill running. The data were aligned with each individual's age of peak height velocity. The maximal oxygen uptake (\(\dot V\)O2max; ml · kg−1 ...

This paper examines how selected physiological performance variables, such as maximal oxygen uptake, strength and power, might best be scaled for subject differences in body size. The apparent dilemma between using either ratio standards or a linear adjustment method to scale was investigated by considering how maximal oxygen uptake (1·min−1), peak and mean power output (W) might best be adjusted for differences in body mass (kg). A curvilinear power function model was shown to be theoretically,...

The purposes of this study were to provide baseline data on the peak oxygen consumption (VO2) of British children, aged 11–16 years and to examine the peakVO2 of children in relation to their pubertal stage of development. The peakVO2 of 226 boys and 194 girls was determined during either treadmill running or cycle ergometry. The sexual maturity of 320 of the children was estimated using Tanner's indices. PeakVO2 increased with chronological age in both sexes and from about the age of 12 years b...

Abstract The purpose of this study was to compare the maximal exercise performance during cycle ergometry of 34 men and 47 women. External peak power output (OPP) and optimized pedalling rate (ORPM) were calculated from data gathered during an optimization procedure performed on a friction braked cycle ergometer. In addition, lean leg volume (LLV) and lean upper leg volume (LULV) were determined using an anthropometric technique. Both OPP and ORPM were greater in men than in women (1007+135 vs 6...

ABSTRACT Phase angle is a marker of health and cellular integrity and is used as a tool for predicting nutritional status in children with various health conditions. Despite the fact that physical activity and cardiorespiratory fitness have been shown to provide several health benefits, few studies have evaluated the relationship between phase angle and health parameters, e.g., cardiorespiratory fitness and body composition. Thus, we aimed to evaluate the association between phase angle and card...

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 \( \left( {{\dot{\text{V}}\text{O}}_{2} } \right) \).

.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 rela...

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 \(\dot{{V}}{\text{O}}_{2}\).

Introduction: Decreased respiratory muscle strength in patients with cystic fibrosis (CF) may cause progressive exercise intolerance during cardiopulmonary exercise testing (CPET), and may contribute to the development of chronic respiratory insufficiency. The aim of this study is to evaluate exercise tolerance during CPET of children and adults with clinically stable CF who exhibit different respiratory muscle strength. Methods: Sixty-nine clinically stable CF subjects aged 8 to 33 years underw...
