Effects of Backpack Load and Trekking Poles on Energy Expenditure During Field Track Walking [PDF]

, 2018
This study evaluates the effects of the use of backpack load and trekking poles on feld track walking energy expenditure. Twenty male volunteer pole walkers (age: 22.70 ± 2.89 years; body mass: 77.90 ± 11.19 kg; height: 1.77 ± 0.06 m; percentage of body ...

Validating accelerometry-derived proxies of energy expenditure using the doubly labelled water method in the smallest penguin species

Biology Open, 2021
Understanding energy use is central to understanding an animal's physiological and behavioural ecology. However, directly measuring energy expenditure in free-ranging animals is inherently difficult.

Extreme events reveal an alimentary limit on sustained maximal human energy expenditure

Science Advances, 2019
Maximum sustained energy expenditure in humans is limited by energy intake and strongly tied to event duration. The limits on maximum sustained energy expenditure are unclear but are of interest because they constrain reproduction, thermoregulation, and ...

Resting energy expenditure, activity energy expenditure and total energy expenditure at age 91–96 years [PDF]

British Journal of Nutrition, 2000
There is a limited knowledge concerning energy requirements of the elderly, especially the oldest old (> 80 years). Energy requirements should be estimated from measurements of energy expenditure. For this purpose twenty-one free-living individuals (eight males, thirteen females) aged 91–96 years living in Göteborg, Sweden were studied.

Consistency of metabolic responses and appetite sensations under postabsorptive and postprandial conditions [PDF]

, 2012
The present study aimed to investigate the reliability of metabolic and subjective appetite responses under fasted conditions and following consumption of a cereal-based breakfast. Twelve healthy, physically active males completed two postabsorption (PA)

Energy requirements of adults. [PDF]

, 2005
OBJECTIVES: To describe issues related to energy requirements of free living adults and discuss the importance of basal metabolic rate (BMR) and their relationships to total energy expenditure (TEE ) and physical activity level (PAL, derived as TEE/BMR ...

Acute and chronic effects of multivitamin/mineral supplementation on objective and subjective energy measures [PDF]

, 2020
Background: Vitamins and minerals play an essential role within many cellular processes including energy production and metabolism. Previously, supplementation with a multivitamin/mineral (MVM) for ≥28 days resulted in improvements to cognition and ...

Postprandial energy expenditure in whole-food and processed-food meals: implications for daily energy expenditure

Food & Nutrition Research, 2010
Background: Empirical evidence has shown that rising obesity rates closely parallel the increased consumption of processed foods (PF) consumption in USA. Differences in postprandial thermogenic responses to a whole-food (WF) meal vs.

Accuracy in Wrist-Worn, Sensor-Based Measurements of Heart Rate and Energy Expenditure in a Diverse Cohort

bioRxiv, 2016
Background The ability to measure activity and physiology through wrist-worn devices provides an opportunity for cardiovascular medicine. However, the accuracy of commercial devices is largely unknown.
