      Running economy, which has traditionally been measured as the oxygen cost of running at a given velocity, has been accepted as the physiological criterion for ‘efficient’ performance and has been identified as a critical element of overall distance running performance. There is an intuitive link between running mechanics and energy cost of running, but research to date has not established.   ObjectiveTo determine energy expenditure in kilocalories (kcal) during sexual activity in young healthy couples in their natural environment and compare it to a session of endurance exercise. MethodsThe study population consisted of twenty one heterosexual couples (age: ± years old) from the Montreal region. Free living energy expenditure during sexual activity and the endurance.

    RESULTS The subjects' TEE measured by the DLW method was 1, ± kcal/day in boys and 1, ± kcal/day in girls, whereas resting energy expenditure was 1, ± kcal/day. List of orders of magnitude for energy; Factor (joules) SI prefix Value Item 10 − ×10 −34 J: Photon energy of a photon with a frequency of 1 hertz.: 10 − 2×10 −33 J: Average kinetic energy of translational motion of a molecule at the lowest temperature reached, picokelvins as of 10 − ×10 −28 J: Energy of a typical AM radio photon (1 MHz) (4×10 −9 eV).

    The adult men in both groups had a mean weight of 56&+-;4 kg and were approximately the same weight at the beginning and end of the year's investigation. The savannah group were taller and leaner than the forest group. The comparison is expressed as follows: Energy requirements or intakes of 56 kg men (kcal/day) in hot climates. The aim of present study was to analyze the oxygen uptake, the heart rate, and the energetic expenditure of women in two water aerobics routines: continuous and interval. The sample comprised ten voluntary active women who performed two water aerobics routines with a minimal interval of 48 hours and randomized order. Each routine was performed with the same exercises and duration, .

Comparison of the energy expenditures and mechanical efficiency of boys and young men by Mina Marie (Wolf) Lamb Download PDF EPUB FB2

Men and women completed the same physical E: To characterize and compare the total energy expenditure (TEE) and core temperature responses in men and women working almost continuously for d in an outdoor environment while developing a substantial energy deficit.

METHODS: TEE was measured using doubly labeled water (D(2)O(18)).Cited by:   The high energy cost of armoured walking reduces locomotion speed so, when using the same rate of energy expenditure as young men, older men would only be able to sustain very slow speeds (figure 2).Cited by:   The energy requirement for growth was ignored in this comparison because mean weight gain at this age is only 7 g/d on average, which is equivalent to energy requirement for weight gain of 21 kJ/g Energy expenditure measures Boys Energy expenditure and subsequent nutrient intakes in overfed young by:   Similarly, Brooks and et al.

founded no gender difference for kilocalories per kilogram per kilometre suggests that a presumed shorter stride length that seventy two men and women, yrs old (women were 15 cm shorter than men) did not alter the mechanical efficiency of walking at self-selected speeds (Brooks, Gunn et al., ).Cited by:   Fidgeting-like activities increased energy expenditure in each subject compared with the relevant motionless state.

The energy expenditure of fidgeting-like activities while seated was ± kJ/min greater (P energy expenditure while sitting ties tended to be consistent between subjects and included hand and foot tapping and arm and leg by: M. Jobling, in Reference Module in Life Sciences, Metabolic Rates: Energy Expenditure and Rates of Nitrogenous Excretion.

There are many biotic and abiotic factors that influence energy expenditure and rates of excretion of poikilothermic ectotherms; temperature, oxygen availability, activity, and feeding are among the most important.

For example, an increase in environmental. Estimated energy requirement. The National Academy of Sciences, Institute of Medicine, and Food and Nutrition Board in partnership with Health Canada, developed the EER for males, females, children, infants, and for pregnant and lactating women.[] The EER is defined as an average dietary energy intake which is predicted to maintain energy balance in a healthy adult of a defined age, gender.

Objective: To compare the energy expenditure of adolescents when playing sedentary and new generation active computer games. Design: Cross sectional comparison of four computer games. Setting Research laboratories.

Participants: Six boys and five girls aged 13–15 years. Procedure: Participants were fitted with a monitoring device validated to predict energy expenditure.

The average daily energy expenditure, as physical activity, of Stone Age humans is estimated at approximately MJ ( kcal) and their total caloric intake at approximately MJ ( kcal) (Cordain et al., ). Their subsistence efficiency was thus approximately kJ (kcal) acquired for each kilojoule (kilocalorie) expended in.

The energy expended to transport the body over a given distance (C, the energy cost) increases with speed both on land and in water. At any given speed, C is lower on land (e.g., running or cycling) than in water (e.g., swimming or kayaking) and this difference can be easily understood when one considers that energy should be expended (among the others) to overcome resistive forces since.

In additional analyses according to demographic characteristics, women had less total energy expenditure than men (1, versus 2, kilocalories per week; P = ) and among women, more education was associated with more total energy expenditure (P = after adjusting for covariates).

This was the case for women in both the RA and. Objective To compare the energy expenditure of adolescents when playing sedentary and new generation active computer games. Design Cross sectional comparison of four computer games.

Setting Research laboratories. Participants Six boys and five girls aged years. Procedure Participants were fitted with a monitoring device validated to predict energy expenditure.

The effect of target location, speed, and handedness on the average total mechanical energy and movement efficiency is studied in 15 healthy subjects (7 males and 8 females with age +/- years old) performing full body reaching movements. Comparison of energy expenditure variables between boys and girls.

Also shown in Table 1 are data on TEE, measures of physical activity, and TEE as a percentage of published reference values for energy intake. The FAO/WHO/UNU recommendations used were those based on body weight as the major predictor of energy requirements, classified.

Greater energy efficiency can reduce energy costs to consumers, enhance environmental quality, maintain and enhance our standard of living, increase our freedom and energy security, and promote a strong economy.

Background and Aims: To assess the degree of agreement between indirect calorimetry and five equations commonly used to predict resting energy expenditure (REE) in obese and non-obese children and adolescents.

Methods: In children and adolescents (57 obese and 59 non-obese) aged between and years, REE was measured (MREE) by open-circuit indirect calorimetry under. However, when daily energy intake is compared in the cohort of subjects from NHANES III, men consumed more energy, even after adjusting for fat-free mass ( kJkg −1 versus kJkg −1) [1, 10].

One possible explanation is that women are more efficient at conserving energy and storing it .Objectives: To measure total energy expenditure (TEE) and total body water (TBW) in healthy Swedish children 9 or 14 months of age.

To compare their TEE with current recommendations for energy intake.Resting energy expenditure remains elevated as long as you exercise at least three days a week on a regular basis. Because resting energy expenditure accounts for 60% to 75% of the calories you burn each day, any increase in resting energy expenditure is extremely important to your weight-loss effort.
