“…However, the subjects with active exercise habits did not show significantly higher PAL compared with non-exercisers, though exercisers engaged in exercise 2277141 min/week on average. Schoeller et al (1997) and Weinsier et al (2002) suggested that a PAL of around 1.7 might be required to prevent weight regain in post-obese females. Brooks et al (2004) also suggested that most adults maintaining a BMI in the healthful range had PAL values 41.6.…”

Objective: To measure total energy expenditure (TEE) for normal healthy Japanese by the doubly labelled water (DLW), and to compare the physical activity level (PAL) among categories classified by the categories used in daily reference intake (DRI), Japan and the International Physical Activity Questionnaire (IPAQ). Subjects and methods: A total of 150 healthy Japanese men and women aged 20-to 59-year-old living in four districts of Japan. TEE was measured by the DLW method, and the PAL was calculated from TEE divided by basal metabolic rate. Simultaneously with TEE measurement, the PAL was assessed employing the categories used in DRI, Japan and IPAQ. Results: The average TEE and PAL were 10.7871.67 MJ/day and 1.7270.22 for males and 8.3771.30 MJ/day and 1.7270.27 for females, respectively. The subjects in the highly active categories assessed by both DRI and IPAQ showed significantly higher PAL compared with less active categories. However, PALs among light and moderate categories by DRI, and insufficient and sufficiently active by IPAQ were not significantly different. Conclusions: In developed countries, highly active subjects could be assessed by a simple questionnaire. However, the questionnaire should be improved to clarify the sedentary to moderately active subjects by assessing carefully very light to moderate physical activity.

“…NWCR members report expending an average of 2,682 kcal per week by means of physical activity, and nearly 90% report regular exercise. 60 Using the gold-standard doubly labeled water method to obtain activity levels, Schoeller et al 61 and Weinsier et al 62 found that 77-80 min per day of moderate intensity activity added to a sedentary lifestyle was needed to prevent weight regain in the year after weight loss.…”

The role of physical activity in producing and maintaining weight loss

SummaryThe majority of randomized, controlled trials (RCTs) show only modest weight loss with exercise intervention alone, and slight increases in weight loss when exercise intervention is added to dietary restriction. In most RCTs, the energy deficit produced by the prescribed exercise is far smaller than that usually produced by dietary restriction. In prospective studies that prescribed high levels of exercise, enrolled individuals achieved substantially greater weight losscomparable to that obtained after similar energy deficits were produced by caloric restriction. High levels of exercise might, however, be difficult for overweight or obese adults to achieve and sustain. RCTs examining exercise and its effect on weight-loss maintenance demonstrated mixed results; however, weight maintenance interventions were usually of limited duration and long-term adherence to exercise was problematic. Epidemiologic, cross-sectional, and prospective correlation studies suggest an essential role for physical activity in weight-loss maintenance, and post hoc analysis of prospective trials shows a clear dose-response relationship between physical activity and weight maintenance. This article reviews the role of physical activity in producing and maintaining weight loss. We focus on prospective, RCTs lasting at least 4 months; however, other prospective trials, meta-analyses and large systematic reviews are included. Limitations in the current body of literature are discussed.

“…The index is useful for comparing activity levels among subjects with different energy economies of exercise, as we have found in previous studies. 1 Dual-energy X-ray absorptiometry (DXA) Percent fat was determined by DXA (DPX-L, Lunar Radiation Corp., Madison, WI, USA). The scans were analyzed using the Adult Software (Version 1.33).…”

Aerobic fitness, physiologic difficulty and physical activity in Black and White women

PURPOSE:The purpose of this work was to determine if racial differences in maximum oxygen uptake (VO 2 max) and difficulty in doing submaximum (sub) exercise tasks contribute to activity-related energy expenditure (AEE) and activity-related time equivalent (ARTE) index, an index of time spent in physical activity. METHODS: Subjects were 35 Black and 39 White sedentary premenopausal women group matched for age, weight and body composition. Percent fat was determined by dual energy X-ray absorptiometry, AEE by doubly labeled water and sleeping energy expenditure, ARTE index by AEE and energy cost above sleeping for five exercise tasks, and VO 2 max by a graded exercise test. Subexercise oxygen uptake was measured during walking at 3 mph on the flat and up a 2.5% grade, climbing stairs, and riding a bike ergometer at 50 W. Difficulty of exercise was assessed during the subexercise and taken as heart rate, ventilation, and ratings of perceived exertion (RPE) and expressed as a % of the individual's maximum. RESULTS: VO 2 max was related to AEE (r ¼ 0.29, Po0.04) and to ARTE index (r ¼ 0.37, Po0.01). All three difficulty measures were related to AEE (r ¼ À0.35 to À0.42, P-valueso0.02) and the ARTE index (r ¼ À0.49 to À0.52, all P-valueso0.01), with the exception of RPE with ARTE (r ¼ À0.27, P ¼ 0.10). Compared to Black women, White women had significantly higher VO 2 max (12%), AEE (45%) and ARTE (50%), and significantly less physiologic difficulty of performing the subexercise tasks: heart rate (5%), ventilation (13%), and RPE (8%). Significant racial differences in AEE and ARTE disappeared after adjusting for any of the three difficulty measures. CONCLUSIONS: These results show that more participation in free-living physical activity is related to greater VO 2 max and less difficulty in being active. In addition, lower levels of physical activity found in Black women may be partially explained by lower VO 2 max and increased difficulty of engaging in physical activities.
