Patients with chronic respiratory diseases have been found to develop malnutrition as a result of enhanced resting metabolic rate (RMR) associated with exacerbated ventilatory impairment. It is therefore necessary to measure each individual’s required amount of energy in order to provide nutritional support. There are few reports regarding the RMR of patients with chronic respiratory diseases t...
Substantial research efforts have been aimed at identifying novel targets to increase resting metabolic rate (RMR) as an adjunct approach to the treatment of obesity. Respirometry (one form of "indirect calorimetry") is unquestionably the dominant technique used in the obesity research field to assess RMR in vivo, although this method relies upon a lengthy list of assumptions that are likely to...
The direct effects of physical activity interventions on energy expenditure are relatively small when placed in the context of total daily energy demands. Hence, the suggestion has been made that exercise produces energetic benefits in other components of the daily energy budget, thus generating a net effect on energy balance much greater than the direct energy cost of the exercise alone. Resti...
Resting metabolic rate (RMR) and body composition were measured in 44 initially nonoverweight girls at three time points relative to menarche: premenarche (Tanner stage 1 or 2), menarche (+/-6 mo), and 4 yr after menarche. Mean absolute RMR was 1,167, 1,418, and 1,347 kcal/day, respectively. Absolute RMR was statistically significantly higher at menarche than at 4 yr after menarche despite stat...
PURPOSE There has not been a recent comprehensive effort to examine existing studies on the resting metabolic rate (RMR) of adults to identify the effect of common population demographic and anthropometric characteristics. Thus, we reviewed the literature on RMR (kcal·kg(-1)·h(-1)) to determine the relationship of age, sex, and obesity status to RMR as compared with the commonly accepted value ...
BACKGROUND/OBJECTIVES Athletes generally desire changes in body composition in order to enhance their athletic performance. Often, athletes will practice chronic energy restrictions to attain body composition changes, altering their energy needs. Prediction of resting metabolic rates (RMR) is important in helping to determine an athlete's energy expenditure. This study compared measured RMR of ...
پردازش تُنُک سیگنال ها به عنوان ابزاری قدرتمند و جایگزینی کارآ برای تبدیلات کلاسیک کامل طی دهه ی اخیر به شدت مورد توجه قرار گرفته است. در این رهیافت می خواهیم از بین تعداد زیادی سیگنال پایه، که در حالت کلی تعدادشان خیلی بیشتر از بعدشان است، کم ترین تعداد را برای نمایش یک سیگنال انتخاب کنیم. هر سیگنال پایه یک «اتم» و مجموعه ی این اتم ها یک «دیکشنری» نامیده می شود. این عمل در حالت کلی دشوار بوده و ...
چکیده مثال های بیشماری از تولید نقشه های پوششی و کاربری اراضی در مقیاس های جهانی، منطقه ای و محلی از تصاویر چندطیفی وجود دارد. بیشتر آنها هر پیکسل تصویر را بعنوان مشاهده مستقل، صرف نظر از مفهوم مکانی، طبقه بندی می کنند. یکی از مهمترین مشکلات تولید نقشه های پوششی و کاربری اراضی از تصاویر رقومی ترکیب پاسخ طیفی از عوارض مختلف است. همچنین در تهیه نقشه از مناطق ناهموار و کوهستانی، توپوگرافی زمین مس...
Fish oil (FO) has been shown to have beneficial effects in the body via incorporation into the membranes of many tissues. It has been proposed that omega-3 fatty acids in FO may increase whole body resting metabolic rate (RMR) and fatty acid (FA) oxidation in human subjects, but the results to date are equivocal. The purpose of this study was to investigate the effects of a 12 week FO supplemen...
We tested the hypothesis that resting metabolic rate (RMR) declines with age in physically active men (endurance exercise > or =3 times/wk) and that this decline is related to weekly exercise volume (h/wk) and/or daily energy intake. Accordingly, we studied 137 healthy adult men who had been weight stable for > or =6 mo: 32 young [26 +/- 1 (SE) yr] and 34 older (62 +/- 1 yr) sedentary males (in...
