本技术说明描述了通过使用多传感器板（MSB）测量斜率来改善活动能量消耗估计的方法。10名成年人穿着MSB和移动的热量计走过了4公里（2.5英里）的路程。仅使用加速度计（基础）和4种测量斜率的方法估计能量消耗。气压计和全球定位系统方法将准确性从基础提高了11%（p< 0.05），总体提高了86%。使用MSB测量坡度可改善实地活动期间的能源消耗估计。
This technical note describes methods to improve activity energy expenditure estimates by using a multi-sensor board (MSB) to measure slope. Ten adults walked over a 4-km (2.5-mile) course wearing an MSB and mobile calorimeter. Energy expenditure was estimated using accelerometry alone (base) and 4 methods to measure slope. The barometer and global positioning system methods improved accuracy by 11% from the base (p< 0.05) to 86% overall. Measuring slope using the MSB improves energy expenditure estimates during field-based activities.
