全球定位系统（GPS）接收器与集成的心率（HR）监测的最新发展提供了一种新的方法来估计与儿童的运动相关的能量消耗。这项可行性研究的目的是在新西兰的39名小学学龄儿童中试验GPS监测和HR监测的组合。空间位置和人力资源数据记录在学校午休期间使用集成的GPS/HR接收器（1 Hz）。儿童平均总距离为1.10 +/- 0.56公里，速度范围为0至18.6公里/小时（-1）。活动模式的特点是由较长时间的缓慢速度的中等到高速的短爆发。此外，男孩的平均速度高于女孩（分别为1.77 +/- 0.62 km h（-1）和1.36 +/- 0.50 km h（-1）; p = 0.003）。在0 km h（-1）（静止）时花费的时间百分比范围为0.1%至21.3%，平均值为6.4 +/-4.6%。这些数据表明，虽然孩子们在午餐时间相对活跃，但他们花了很大一部分时间从事缓慢或静止的体力活动。此外，HR、平均速度和静止时间之间的关联表明，以较快速度移动的儿童比以较慢速度移动的儿童消耗更多的能量。我们的结论是，GPS和HR监测相结合的方法是一个很有前途的新方法，调查儿童的游戏相关的能量消耗。还可以将全球定位系统数据与地理信息系统相结合，以检查儿童在哪里玩耍和积累体力活动。(C)2008年澳大利亚运动医学。由爱思唯尔有限公司出版。保留所有权利。
The recent development of global positioning system (GPS) receivers with integrated heart rate (HR) monitoring has provided a new method for estimating the energy expenditure associated with children's movement. The purpose of this feasibility study was to trial a combination of GPS surveillance and HR monitoring in 39 primary-aged children from New Zealand. Spatial location and HR data were recorded during a school lunch break using an integrated GPS/HR receiver (1 Hz). Children averaged a total distance of 1.10 +/- 0.56 km at speeds ranging from 0 to 18.6 km h(-1). Activity patterns were characterised by short bursts of moderate to high speeds followed by longer periods of slow speeds. In addition, boys averaged higher speeds than girls (1.77 +/- 0.62 km h(-1) and 1.36 +/- 0.50 km h(-1), respectively; p = 0.003). The percentage of time spent at 0 km h(-1) (stationary) ranged from 0.1% to 21.3% with a mean of 6.4 +/- 4.6%. These data suggest that while children were relatively active during the lunch period, they spent a substantial portion of time engaged in slow or stationary physical activities. Furthermore, associations between HR, average speed, and stationary time demonstrated that children who moved at faster speeds expended more energy than those who moved at slower speeds. We conclude that the combined approach of GPS and HR monitoring is a promising new method for investigating children's play-related energy expenditure. There is also scope to integrate GPS data with geographic information systems to examine where children play and accumulate physical activity. (C) 2008 Sports Medicine Australia.
