Estimation of Total Daily Energy Expenditure and Its Components by Monitoring the Heart Rate of Japanese Endurance Athletes

As the prevalence of obesity rises worldwide, researchers pursue explanations for the phenomenon, particularly those relevant to energy expenditure. Non-exercise activity thermogenesis, or NEAT, has been identified as an inconspicuous but appreciable component of total daily energy expenditure. Demands of certain occupations discourage time for planned physical activity and clearly diminish NEAT, and thereby contribute to sedentary behaviors that underlie increased adiposity. Prolonged sitting during the workday has specifically been identified as a risk factor for obesity and chronic disease independent of existing risk factors. Practical strategies have been launched by industry to increase NEAT during the workday. Workstations that involve maintaining balance while sitting on an exercise ball, standing, pedaling while sitting, and walking at a treadmill desk have been developed to counter extended periods of sedentary behavior at work. While data are limited particularly for chronic benefits, the stations that promote the most movement – the pedaling and walking stations – increase METS and energy expenditure more so than the other alternatives. The drawback to greater motion may be reduced attention to the desk job and therefore, reduced cognitive function; however, the data are inconsistent and the benefit for health may outweigh small distractions for some tasks at the desk.

The Difference

Abstract Objectives To assess different methods of estimating energy balance (EB) and its components in a sample of older people (age ≥ 60 years) living in a tropical city in Brazil. Methods EB was calculated in 85 older individuals (69 women) as the difference between energy intake (EI), obtained by three 24-hour dietary recalls on nonconsecutive days, and total daily energy expenditure (TDEE) estimated by 24-hour physical activity recalls (24hPAR, subjective method) and accelerometry (ACC, objective method) on the same days. Basal metabolic rate (BMR) was estimated by a validated local predictive equations derived from a sample of healthy adults from the same city and by international equations (Schofield). Resting energy expenditure (MET) was also estimated by local predictive equation and the conventional value of 3.5 mL.kg−1.min−1. Anthropometry and % body fat (DXA) assessment was also obtained. Results Mean (SD) age was 69.0 (5.5) years with a mean BMI of 26.7 (4.4) kg.m−2 and %BF of 39.4 (7.9). BMR from locally-derived equations (1050.7 ± 188.7 kcal.day−1) was significantly lower than BMR estimated by the Schofield's equation (1286.5 ± 145.3 kcal.day−1). Likewise, predicted MET was significantly lower than the conventional value. Despite the high prevalence of overweight (66% with BMI ≥ 25 kg.m−2), EB was always negative for the 24hPAR method (−863.5 ± 799.5 kcal.day−1) but positive (252.1 ± 726.6 kcal.day−1) with the ACC method when MET was calculated with population-specific equations. EB estimated by ACC was also negative (−122.7 ± 781.0 kcal.day−1) using the conventional MET value. Conclusions The findings of this study indicate that EB is negative when the subjective method of TDEE estimation is used but becomes positive with the objective method. It is also evident that BMR and MET equations derived from samples of the population of interest may help improve the final estimates of TDEE and EB in older adults.

Total Daily Energy Expenditure

Reports of low energy intakes in trained female athletes imply they have an increased energetic efficiency. To address this question, we determined how energy balance was achieved in endurance-trained females cyclists and lean controls (n=5 in each group). Daily energy expenditure was measured by using standardized physical activity protocols in a whole room calorimeter on two separate occasions: a cycling day and a noncycling day. Energy intake for weight maintenance was determined by a period of controlled feeding 5 days before and the day of each energy expenditure measurement. Energy balance was achieved in the cyclists on the cycling day while they consumed 2,900–3,000 kcal (their usual condition) and in controls on the noncycling day while they consumed 2,100–2,200 kcal (their usual condition). Total daily energy expenditure was not significantly different between the cyclists and controls on the noncycling day with both groups performing similar levels of activity. On the cycling day, daily energy expenditure was significantly greater in the cyclists vs. controls (P<0.03) as a result of their greater amount of cycling activity. Components of daily energy expenditure, i.e., resting metabolic rate and thermic effect of food and activity (noncycling), were not significantly different between groups. Overall, we found no significant increase in the energetic efficiency of endurance-trained female cyclists compared with controls.
