“…In a comparison of the normative curves established for TTE in the present study with those provided by Dubowy et al, 29 similar patterns were obtained. In boys, the normative curve for TTE on the FTT showed an almost linear increase with age.…”

“…In girls, the increase in TTE on the FTT started to level off at approximately 10 years of age. The endurance time achieved by male participants in the study of Dubowy et al 29 increased until the age of 19 years, whereas in female participants it decreased continuously from puberty. Van der Cammen-van Zijp et al 30 and Binkhorst et al 32 also obtained similar patterns.…”

Background Recent research has shown that the Fitkids Treadmill Test (FTT) is a valid and reproducible exercise test for the assessment of aerobic exercise capacity in children and adolescents who are healthy. Objective The study objective was to provide sex- and age-related normative values for FTT performance in children and adolescents who were healthy, developing typically, and 6 to 18 years of age. Design This was a cross-sectional, observational study. Methods Three hundred fifty-six children and adolescents who were healthy (174 boys and 182 girls; mean age=12.9 years, SD=3.7) performed the FTT to their maximal effort to assess time to exhaustion (TTE). The least-mean-square method was used to generate sex- and age-related centile charts (P3, P10, P25, P50, P75, P90, and P97) for TTE on the FTT. Results In boys, the reference curve (P50) showed an almost linear increase in TTE with age, from 8.8 minutes at 6 years of age to 16.1 minutes at 18 years of age. In girls, the P50 values for TTE increased from 8.8 minutes at 6 years of age to 12.5 minutes at 18 years of age, with a plateau in TTE starting at approximately 10 years of age. Limitations Youth who were not white were underrepresented in this study. Conclusions This study describes sex- and age-related normative values for FTT performance in children and adolescents who were healthy, developing typically, and 6 to 18 years of age. These age- and sex-related normative values will increase the usefulness of the FTT in clinical practice.

“…The expression of peak V O 2 as an absolute value, rather than as a percentage of predicted normal value based on sex and age, might explain this finding, particularly because there is an overall trend for increasing peak V O 2 (in mL ⅐ kg Ϫ1 ⅐ min Ϫ1 ) in the young. 17 Similarly, Das and colleagues 18 showed that only 21% of children on the waiting list for HTx have a peak V O 2 below the 14 mL ⅐ kg Ϫ1 ⅐ min Ϫ1 cutoff currently used to recommend HTx in adults. Their small study also showed that the use of absolute peak V O 2 value (in mL ⅐ kg Ϫ1 ⅐ min Ϫ1 ) can be misleading in children because of differences in body size and muscle mass.…”

Peak Oxygen Uptake Correlates With Survival Without Clinical Deterioration in Ambulatory Children With Dilated Cardiomyopathy

Background-Children stable at home with dilated cardiomyopathy remain at risk of death; there is evidence of survival benefit for transplantation out to 4 years postoperatively. The limited supply of donor organs makes risk stratification imperative, but although cardiopulmonary exercise test is well established as a powerful tool in adults with heart failure, no published studies have linked oxygen uptake to prognosis in children. Methods and Results-Between 2001 and 2009, using cardiopulmonary exercise test and echocardiography, we studied 82 children (mean age, 13.5Ϯ2.3 years) with dilated cardiomyopathy. All were ambulatory, outpatients, and Ͼ120 cm in height. All children completed a symptom-limited maximal exercise test. Resting left ventricular shortening fraction was 20Ϯ9%; peak heart rate was 87Ϯ13% of predicted; peak oxygen uptake (V O 2 ) was 67Ϯ22% of predicted; and ventilatory efficiency was 32Ϯ8. Follow-up was available for 100% of the children, and was a mean of 32.3Ϯ7.5 months. Eighteen patients reached the defined clinical end point of death or listing for urgent heart transplantation. On univariate analysis, left ventricular shortening fraction, peak heart rate, peak V O 2 , peak systolic blood pressure, and ventilatory efficiency were all associated with adverse outcome. On multivariable Cox analysis, only peak V O 2 (Pϭ0.003) was associated with the study end point. Patients with a peak V O 2 Յ62% of predicted had a higher 24-month event rate (50.6% versus 4.4%; hazard ratio, 10.78). Conclusions-We have demonstrated that a cardiopulmonary exercise test is feasible in ambulatory children with dilated cardiomyopathy who are Ͼ120 cm height and for the first time have linked peak V O 2 with outcome in children.

“…Sir, The article of Dubowy et al 1 provides reference values for maximal exercise performance evaluated by a simple treadmill test in a population ranging from 4 to 75 years of age, classified according to gender and age both with and without relation to body mass and body surface area. The purpose deserves attention, especially in view of the increasing group of adults with congenital cardiac disease, whose exercise capacity requires a comparison with normal values.…”

“…Dubowy et al 1 rely on body mass, thus admitting an undue significance to the fat component of the body, as lean body mass is not at hand. The use of body mass as a reference parameter for cardiovascular performance may thus turn out to be a method that, indirectly, estimates overweight.…”
