Lower excess postexercise oxygen consumption and altered growth hormone and cortisol responses to exercise in obese men.

CONTEXT Obesity is associated with altered patterns of substrate utilization at rest and during exercise. OBJECTIVE The relationship between obesity and fat oxidation during recovery from exercise was examined. HYPOTHESIS The postexercise shift toward fat oxidation is blunted in the obese state, reflected by higher respiratory exchange ratio (RER), blunted GH, and increased cortisol values ...

Excess postexercise oxygen consumption after aerobic exercise training.

Literature examining the effects of aerobic exercise training on excess postexercise oxygen consumption (EPOC) is sparse. In this study, 9 male participants (19-32 yr) trained (EX) for 12 wk, and 10 in a control group (CON) maintained normal activity. VO(2max), rectal temperature (T(re)), epinephrine, norepinephrine, free fatty acids (FFA), insulin, glucose, blood lactate (BLA), and EPOC were m...

the effect of exercise on cortisol responses and energy expenditure in obese and lean men

to investigate the effect of exercise on cortisol responses and energy expenditure in obese and lean men, we measured the energy expenditure (ee) and salivary cortisol responses of six obese (age 22.83± 1.9 yr; vo2max,35.45±3.9 ml/min/kg; bmi 18.2±1.3 kg/m2) sedentary men. the protocol was running on a treadmill for 30 minutes with 65% maximal oxygen consumption. student t-test and one-way anov...

Immunoreactive and bioactive growth hormone responses to resistance exercise in men who are lean or obese.

It has been suggested that obese individuals have a blunted growth hormone (GH) response to spontaneous and stimulated GH secretion. The present study was designed to examine the effects of a high-volume, whole body acute resistance exercise (RE) protocol on immunoreactive GH (iGH), bioactive GH (bGH), and GH-binding protein (GHBP) in sedentary lean and obese men. Nine obese (mean ± SD: 20.8 ± ...

Is postexercise hypotension related to excess postexercise oxygen consumption through changes in leg blood flow?

After a single bout of aerobic exercise, oxygen consumption remains elevated above preexercise levels [excess postexercise oxygen consumption (EPOC)]. Similarly, skeletal muscle blood flow remains elevated for an extended period of time. This results in a postexercise hypotension. The purpose of this study was to explore the possibility of a causal link between EPOC, postexercise hypotension, a...
