Abstract

生体情報の一つであるHRを用いてエネルギー消費量を予測する24h-HRR法の基準値について, 成人男女 (20~69歳) を被験者として, 検討を行い次のような結果が得られた。<BR>1) 対象被験者の睡眠時間は, 年齢, 性別, 職業を問わず, 平均値で450±51分であり, 1日の約30%を占めている。睡眠時間帯は, 24時間HRのトレンドグラフ上で判別がきわめて明確なうえ, 被験者の睡眠時HRの日変動は, 3.5±1.7beats/minと小さく, 24h-HRR法の基準値として利点が大きいことが明らかにされた。<BR>2) 24h-HRR法によって, 1日の総エネルギー消費量を予測する場合, 基準値としてSHR-II (睡眠時約6時間のHRの平均値に1.2を乗じた値) を用いると, VO<SUB>2</SUB>/HR法によって得られたエネルギー消費量推定値に近似した値 (誤差, 1.9±5.6%) となり, 非常に高い正相関 (r=0.958, p<0.001) が得られた。<BR>以上の結果より, 24h-HRR法における基準値として, SHR-IIを適用することは, 簡便で, かつ本法によるエネルギー消費量予測値の精度をより高めることになり, 基準値として最も妥当性が高いと判断された。

In order to estimate the daily energy expenditure of healthy (free-living) adults, a simpler and more accurate technique was developed by modifying the 24h heart rate ratio (24h-HRR) method of Hashimoto <I>et a</I>l. (1987). Seventeen healthy adults, 8 men and 9 women, aged 20-69 years, were employed for the experiment, and their heart rate (HR) was monitored with a daily trend graph. To calculate the daily energy expenditure, the method originally defines the 24h-HRR as the mean of the 24h-HR divided by resting HR×100. In the present study, the following three standard values, instead of resting HR, were employed to divide into the mean 24h-HR: 1) T-RHR; the mean value of resting HR for 15-30 min at 2h after breakfast obtained from the daily trend graph, 2) SHR-I; the mean value of HR for 6h during sleep obtained from the trend graph divided by 0.9, 3) SHR-II; the mean value of HR for 6h during sleep multiplied by 1.2. The values of daily energy cost calculated by the 24h-HRR method using these three standards were compared with those obtained by the VO<SUB>2</SUB>/HR method. The regression of the daily energy expenditure by the 24h-HRR method using SHR-II on that by the VO<SUB>2</SUB>/HR method was y=0.9570x+152 (kcal/day) and showed the highest correlation coefficient (r=0.958), with an average error of 1.9±5.9%. These results suggest that the use of SHR-II for the 24h-HRR method gives good predictive values of daily energy expenditure more easily than the original method.
