“…The average value of PAL was near 1.75, with 1.60 and 1.90 corresponding to the 25th percentile and the 75th percentile, respectively. The representative value of 1.75 is comparable to those values obtained in the general populations of developed countries; and other studies among Japanese adults appear to support this value [18][19][20][21] . There were no significant differences in PAL among age groups and genders 17) , although Speakman and Westerterp reported small gender differences in 528 subjects who underwent PAL measurement in Maastricht, the Netherlands 22) .…”

Physical activity surveillance at a population level is important. The National Health and Nutrition Survey of Japan has been carried out annually, and two kinds of assessments for physical activity are included in the survey: total step counts per day, measured by a pedometer, and questions on exercise habits. From peak values seen in 1998 -2000, time trends display a decline of age-adjusted mean steps per day, and the average percentage of regular exercisers has increased only in the age group of 50 years old or higher. As for standard or target values of physical activity, the Dietary Reference Intakes (DRIs) for Japanese presents standard values of physical activity levels (total energy expenditure divided by basal metabolic rate) for each gender and age group. The moderate value of physical activity level for adults is 1.75. Furthermore, the Exercise and Physical Activity Guide for Health Promotion 2006 (Exercise Guide 2006) was released based on the "Exercise and Physical Activity Reference for Health Promotion 2006" (EPAR2006). The reference values were set as 23 MET-hours/week for physical activity and 4 MET-hours/week for exercise. The former value is equivalent to 8000 to 10000 daily steps. Thus, Japan has established target values for physical activity and exercise habits, and daily steps have been investigated in the Japanese population. However, the target or standard values of physical activity are not sufficiently linked to the nationwide surveillance of actual levels of physical activity. Therefore, development of physical activity evaluation methods for Japanese is necessary.

“…The intake of protein, fat and carbohydrate assessed from this questionnaire correlated with data obtained from dietary records, with Pearson's correlation coefficients ranging from 0·38 to 0·68 (16) . The mean food quotient of subjects in the present study was 0·87 (SD 0·02), which is very similar to the values of 0·87 (SD 0·03) for Japanese adults (17) and 0·86 (SD 0·04) for elderly Japanese subjects (9) . TEE DLW was expressed as mean TEE DLW per d over the study period.…”

The present study compared the accuracy of triaxial accelerometry and the doubly labelled water (DLW) method for measuring physical activity (PA) in Japanese adolescents. A total of sixty adolescents aged 12-15 years were analysed. The total energy expenditure (TEE) was measured over 7 d by the DLW method and with an EW4800P triaxial accelerometer (Panasonic Corporation). The measured (RMR m ) and predicted RMR (RMR p ) were 5·7 (SD 0·9) and 6·0 (SD 1·0) MJ/d, respectively. TEE measured by the DLW method and accelerometry using RMR m or RMR p were 11·0 (SD 2·6), 10·3 (SD 1·9), and 10·7 (SD 2·1) MJ/d, respectively. The PA levels (PAL) measured by the DLW method using RMR m or RMR p were 1·97 (SD 0·31) and 1·94 (SD 0·31) in subjects who exercised, and 1·85 (SD 0·27) and 1·74 (SD 0·29) in subjects who did not exercise. The percentage of body fat correlated significantly with the percentage difference between RMR m v. RMR p , TEE, PA energy expenditure (PAEE) and PAL using RMR p , and PAL using RMR m assessed by the DLW method and accelerometry. The present data showed that while accelerometry estimated TEE accurately, it did not provide the precise measurement of PAEE and PAL. The error in accelerometry was attributed to the prediction error of RMR and assessment in exercise.Key words: Junior high school students: Total energy expenditure: Walking step counts: Sports Data from the Ministry of Education, Culture, Sports, Science, and Technology in Japan show that the proportion of obese (more than 120 % of standard body weight for height) Japanese junior high school students (aged 12 -15 years old) is 9·37-10·99 % in boys and 7·89-8·92 % in girls, and that the proportion in boys has increased slightly over the last 20 years (1) . A change in physical activity (PA) may have effected this increase in the proportion of obesity, although data on PA in Japanese adolescents are limited.The proportion of junior high school students participating in daily exercise increased from 1970 to 2000 (2) . However, the PA level (PAL) and the amount of moderate-to-vigorous PA (MVPA) were not established in previous studies.Studies of PA in Japanese adolescents often measured walking steps, as pedometers and accelerometers are very popular tools in Japan. These studies used uniaxial accelerometry to show that junior high school students walk 9450-15 428 steps/d on weekdays and 6375-15 517 steps/d on weekends (3) .Only two studies have measured total PA using the doubly labelled water (DLW) method in Japanese children and adolescents. Hikihara et al. (4) measured PA in high school baseball players (mean age 16·5 years, PAL 2·66), while Adachi et al. (5) measured PA in elementary school students (mean age 11·2 years, PAL 1·47). These studies simultaneously used uniaxial accelerometry, which is used widely in Japan. Hikihara et al. (4) reported that total energy expenditure (TEE) measured by uniaxial accelerometry correlated strongly with DLW data (r 0·73, P, 0·05), but underestimated TEE (2 35·3 (SD 3·6) %).Subjective measureme...

“…The accelerometers were worn on the hip above the iliac crest. The validity of the activity monitor was previously established in a study showing that the activity monitor-estimated TEE was comparable with the TEE measured using the DLW method, and the two values were significantly correlated (r = 0.835) 15) . In addition, the energy expenditure assessed by the monitor was significantly correlated with O2 consumption while walking or running at seven speeds ranging from 40 to 160 m/min and during seven daily activities (performing self-care while standing, changing clothes, cooking, simulating eating supper, washing dishes, doing laundry, and using a vacuum cleaner) (R 2 = 0.86) 16) .…”

We compared the physical activity level (PAL) and training and non-training physical activity (PA) between rhythmic gymnasts and lacrosse players. In addition, we aimed to clarify the contribution of training and non-training PA to the PAL. Our study subjects were 11 female rhythmic gymnasts and 11 female lacrosse players. PAL was calculated from the total energy expenditure (TEE) as assessed by the doubly labeled water (DLW) method, and the resting metabolic rate (RMR) was measured using indirect calorimetry. Daily PA and sleep durations were assessed using an activity diary. The intensity (metabolic equivalent, MET) of non-training PA was measured using a tri-axial accelerometer. The amount (MET･h) of training was calculated by subtracting the amount of PA and sleep outside of training from the TEE. There were no significant differences in PAL between rhythmic gymnasts (2.59 ± 0.63) and lacrosse players (2.43 ± 0.46). Rhythmic gymnasts had a longer duration and larger amount of training PA and a shorter duration and smaller amount of non-training PA than did lacrosse players. The mean intensities of training and non-training PA were not significantly different between the groups. PAL was positively correlated with the amount of training in both rhythmic gymnasts (γ s = 0.818) and lacrosse players (γ s = 0.882). There were no significant relationships between PAL and nontraining PA in both groups. Our results indicate that the amount of training strongly affects PAL in these athletes.
