本研究的目的是评估Tritrac-R3D活动监测仪的有效性，这是一种旨在改善身体活动评估的新仪器。与心率监测器和Caltrac活动监测器进行比较。35名儿童（9-11岁）在3个不同的上学日使用所有3种仪器进行监测。Tritrac与心率监测器中度相关（r = 0.58），与Caltrac监测器高度相关（r = 0.88）。通过利用Tritrac和心率监测器的分分钟计时功能，研究人员发现，这些仪器之间的相关性在自由玩耍的情况下（午餐/课间休息、课间休息、放学后）最高，而在活动更有限（上课时间）或有组织（体育课）时较低。Tritrac每分钟评估活动的能力可以大大提高其整体效用。
The purpose of this study was to evaluate the validity of the Tritrac-R3D Activity Monitor, a new instrument designed to improve assessments of physical activity. Comparisons were made with a heart rate monitor and with a Caltrac Activity Monitor. Thirty-five children (ages 9-11 years) were monitored on 3 different school days with all 3 instruments. The Tritrac was moderately correlated with the heart rate monitor (r = .58) and highly correlated with the Caltrac monitor (r = .88). By taking advantage of the minute-by-minute timing capability of the Tritrac and the heart rate monitors, it was discovered that the correlations between these instruments were highest during free play situations (lunch/recess, recess, after school) and were lower when activity was more limited (class time) or structured (physical education). The ability of the Tritrac to assess activity on a minute-by-minute basis may greatly enhance its overall utility.
