We investigated the feasibility of the Actiheart monitor to determine total daily energy expenditure and the validity of the Actiheart step test as an accurate estimate of peak oxygen uptake.
(Equation is included in full-text article.)O2 peak was estimated with the Actiheart step test and compared with a cardiopulmonary exercise test. Total daily energy expenditure was measured using the Actiheart monitor on days with and without classmate coadmission.
Of 26 eligible measurement periods (15 children), 89% participated and 91% could participate safely; however, 35% fulfilled demands for valid monitoring. The percentage of children not completing the monitoring period was 10% (attrition) and adherence to classmate visits was 84%. Forty-eight percent of the measurement periods provided data, and only 27% was calibrated data. Actiheart step test significantly overestimated (Equation is included in full-text article.)O2 peak compared with the Cardio Pulmonary Exercise Test.
Measuring total daily energy expenditure using Actiheart is not feasible, nor implementable in children with cancer. Furthermore, the Actiheart step test is not a valid test to estimate (Equation is included in full-text article.)O2 peak in children with cancer.
我们研究了Actiheart监测仪测定每日总能量消耗的可行性，以及Actiheart阶梯试验作为峰值摄氧量准确估计值的有效性。
（公式包含在全文中）通过Actiheart阶梯试验估计峰值摄氧量，并与心肺运动试验进行比较。在有同学陪住和无同学陪住的日子里，使用Actiheart监测仪测量每日总能量消耗。
在26个符合条件的测量期（15名儿童）中，89%的儿童参与，91%的儿童能够安全参与；然而，35%的测量期满足有效监测的要求。未完成监测期的儿童比例为10%（失访），同学探访的依从率为84%。48%的测量期提供了数据，只有27%是校准后的数据。与心肺运动试验相比，Actiheart阶梯试验显著高估了（公式包含在全文中）峰值摄氧量。
使用Actiheart测量癌症儿童的每日总能量消耗不可行，也无法实施。此外，Actiheart阶梯试验不是估计癌症儿童（公式包含在全文中）峰值摄氧量的有效试验。
