客观化
这项研究的目的是检查卡路里计数器个人活动计算机(CC方法)对体育活动的准确性。
设计
一周或一天的观察性研究。
设置
健康的日本志愿者。
参与者
非运动员(54名男性和53名女性)和38名男性运动员，年龄在13岁到73岁之间。
措施
非运动员一周和运动员一天的每日能量消耗和每周体力活动同时使用CC方法和每日体力活动记录(每日记录法)进行评估。
结果
CC法计算的平均每日能量消耗为9630(标准差，SD，1250)kJ.d-1，非运动员为9530(SD，1120)kJ.d-1；非运动员为7822(SD，768)kJ.d-1和7790(SD，810)kJ.d-1；运动员为1120(SD，1520)kJ.d-1和11580(SD，1580)kJ.d-1。两种方法每日能量消耗的相关系数在0.72~0.90之间。平均每日体力活动量CC法为1520(SD，637)kJ.d-1，非运动员为1580(SD，691)kJ.d-1；非运动员为1033(SD，318)kJ.d-1和1080(SD，346)kJ.d-1；运动员为2770(SD，914)kJ.d-1和3250(SD，1090)kJ.d-1。两种方法测定的日常体力活动相关系数在0.56~0.96之间。
结论
我们的结果表明，CC方法对于评估运动员和非运动员在自由生活活动中的能量消耗可能是足够可靠的。
OBJECTIVE
The aim of this study was to examine the accuracy of the Calorie Counter personal activity computer (CC method) for athletic activity.
DESIGN
An observational study for a week or on a day.
SETTING
Healthy Japanese volunteers.
PARTICIPANTS
Nonathletes (54 males and 53 females) and 38 male athletes, with ages between 13 and 73 years old.
MEASURES
Daily energy expenditure and weekly physical activity were simultaneously assessed using the CC method and a daily record on physical activity (daily record method) for a week for the nonathletes and one day for the athletes.
RESULTS
Mean daily energy expenditures were 9630 (standard deviation, SD, 1250) kJ.d-1 by the CC method, compared with 9530 (SD, 1120) kJ.d-1 by the daily record method for male nonathletes; 7822 (SD, 768) kJ.d-1 and 7790 (SD, 810) kJ.d-1, respectively, for female nonathletes; and 1120 (SD, 1520) kJ.d-1 and 11580 (SD, 1580) kJ.d-1, respectively, for athletes. The correlation coefficients between daily energy expenditures by these two methods ranged from 0.72 to 0.90. Mean daily physical activities were 1520 (SD, 637) kJ.d-1 by the CC method, compared with 1580 (SD, 691) kJ.d-1 by the daily record method for male nonathletes; 1033 (SD, 318) kJ.d-1 and 1080 (SD, 346) kJ.d-1, respectively, for female nonathletes; and 2770 (SD, 914) kJ.d-1 and 3250 (SD, 1090) kJ.d-1, respectively, for athletes. The correlation coefficients between daily physical activities by these two methods ranged from 0.56 to 0.96.
CONCLUSIONS
Our results suggest that the CC method may be reliable enough for assessing the energy expenditure in athletes as well as in nonathletes during free-living activities.
