bpm = beats per minute, EE = energy expenditure, HR = heart rate, N/A = not applicable, REE = resting energy expenditure
While some data suggests that excessive energy intake, not decreased energy expenditure, is the principle cause of the obesity epidemic, other research suggests that and low resting energy expenditure
(REE) or sedentary behaviour is just as important to address.
Total energy expenditure (TEE) consists of resting energy expenditure
(REE), the thermic effect of food (TEF) and activity thermogenesis (AT) (5).
In contrast, resting energy expenditure
(normal-protein diet: 160 kcal/d (95% CI, 102 - 218 kcal/d); high-protein diet: 227 kcal/d (95% CI, 165 - 289 kcal/d)) and body protein (lean body mass) (normal protein diet: 2.
Resting energy expenditure
(normal protein diet: 160 calories/day; high protein diet: 227 calories/day) increased significantly with the normal and high protein diets.
Relative energy intake (REI) was calculated as follows: REI = EI - [ECE - (exercise time x REE)] and for control trial: REI = EI - (exercise time x REE) where EI is the energy intake during the buffet-type meal, ECE is the measured energy cost of exercise, and REE is the measured pre-exercise resting energy expenditure
(Pomerleau et al.
The resting energy expenditure
study included 17 overweight men (mean age 39 years) who were randomized to a sequence of four single-dose treatments of placebo, taranabant 4 mg or 12 mg, and sibutramine 30 mg, with at least 21 days between dosing periods.
Also, as already mentioned, resting energy expenditure
is increased by 10% in HIV-infected people.
Unsurprisingly, the Ireton-Jones equation produces a result that is significantly greater than the resting energy expenditure
in such situations.
Findings also have shown that RT increases resting energy expenditure
and metabolic rate in older women.
They also had a lower resting energy expenditure
The net cost of the exercise is the exercise energy expenditure minus resting energy expenditure
, that is, minus whatever else you would have been doing that day if you were not exercising.
