“…However, it is important to mention that there is a distinction between these two variables. VO 2peak is a measure of aerobic fitness, whereas W peak is a combined measure of both aerobic and anaerobic fitness (11). Since children have an underdeveloped anaerobic energy system (19), the anaerobic energy contribution to the total work performed might be small.…”

“…Pearson's correlations were determined between predicted and measured VO 2peak . Finally, our prediction equation was compared with that of the equation by Dencker et al by entering the individual test results from the children with JIA recruited in this study into the mixed-gender equation by Dencker et al (11). All statistical analyses were performed in SPSS, version 15.0 (SPSS).…”

Objective. To examine whether peak work rate (W peak ) can predict peak oxygen uptake (VO 2peak ) in children with juvenile idiopathic arthritis (JIA). Methods. Ninety-one patients with JIA with a mean ؎ SD age of 11.4 ؎ 2.9 years underwent a cardiopulmonary exercise test in which VO 2peak and W peak were determined. A multivariate regression model was used to formulate a regression equation to predict VO 2peak using W peak and anthropometric and demographic details. This regression equation was subsequently cross-validated using an unrelated data set from children with JIA (n ‫؍‬ 17). Conclusion. This study suggests that W peak is a strong predictor of VO 2peak in children with JIA and may be used as a surrogate measure of VO 2peak in situations where it is not possible to formally assess VO 2peak .

“…Recruitment and methodology of the study cohort has been presented previously [9][10][11][12][13][14][15]. In brief, 477 children (259 boys and 218 girls) living in homogenous middle class areas in Malmö, Sweden, received an invitation to participate in the study and 248 (140 boys and 108 girls) accepted the invitation.…”

Aerobic fitness related to cardiovascular risk factors in young children. and scaled by body mass (ml/min/kg).Total fat mass (TBF) and abdominal fat (AFM) were measured by Dualenergy x-ray absorptiometry. Total body fat was expressed as a percentage of total body mass (BF%), and body fat distribution as AFM/TBF. Systolic and diastolic blood pressure (SBP, DBP), and resting heart rate (RHR) were measured. Mean artery pressure (MAP) and pulse pressure (PP) were calculated. Echocardiography, 2-dimensional guided M-mode, was performed and left atrial diameter (LA) was measured and left ventricular mass (LVM) and relative wall thickness (RWT) were calculated. Z-scores (Value for the individual-mean value for group)/SD were calculated, by sex. Sum of z-scores for DBP, SDP, PP, MAP, RHR, LVM, LA, RWT, BF%, AFM, and AFM/TBF were calculated in boys and girls, separately, and used as composite risk factor score for CVD. Pearson correlation revealed significant associations between VO 2PEAK and composite risk factor score in both boys (r=-0.48 P<0.05), and in girls (r=-0.42, P<0.05). One-way ANOVA analysis indicated significant differences in composite risk factor score between the different quartiles of VO 2PEAK (P<0.001), thus higher VO 2PEAK was associated with lower composite risk factor score for CVD. In conclusion, this sample of young children shows that low VO 2PEAK is associated with an elevated composite risk factor score for CVD in both boys and girls.3

“…It is important to provide reference values for cardiovascular fitness and responses of heart rate (HR) and systolic blood pressure (SBP) to maximal exercise test in children to be able to evaluate the cardiovascular function and health of children and to detect those with abnormal values (Paridon et al, 2006). Although there are a few population studies on cardiovascular fitness or haemodynamic responses to maximal exercise test in healthy children (Dencker et al, 2008;Eiberg et al, 2005;Ten Harkel, Takken, Van Osch-Gevers, & Helbing, 2011), none of them have reported cardiovascular fitness and changes in HR and SBP during and after exercise test.…”

We investigated cardiovascular fitness and haemodynamic responses to maximal cycle ergometer exercise test in children. The participants were a population sample of 425 children (204 girls, 221 boys) aged 6-8 years. Heart rate (HR) and systolic blood pressure (SBP) were measured from the beginning of pre-exercise rest to the end of recovery period. We provided reference values for peak workload and changes in HR and SBP during and after maximal exercise test in girls and boys. Girls had a lower cardiovascular fitness, indicated by peak workload per body weight [mean (2 s) 2.7 (0.9) vs. 3.1 (1.0) W · kg(-1), P < 0.001] and lean mass [mean (2 s) 3.5 (0.9) vs. 3.8 (1.0) W · kg(-1), P < 0.001] than boys. Plateau or decline in SBP close to the end of the test was found in about third of children and was considered a normal SBP response. Girls had a slower HR decrease within 2 min after the test than boys [mean (2 s) 53 (18) vs. 59 (22) beats · min(-1), P < 0.001]. The results are useful for physicians and exercise physiologists to evaluate cardiovascular fitness and haemodynamic responses to exercise in children and to detect children with low exercise tolerance or abnormal haemodynamic responses to exercise.
