Regional glycerol and free fatty acid metabolism before and after meal ingestion.
We measured splanchnic and leg glycerol [and free fatty acid (FFA)] uptake and release in 11 healthy volunteers before and after meal ingestion to assess whether regional FFA-to-glycerol release ratios mirror systemic release ratios. Basal splanchnic triglyceride release was also assessed. Although basal splanchnic glycerol uptake (111 ± 18 μmol/min) accounted for most of systemic glycerol rate...
متن کاملThe influence of sex and obesity phenotype on meal fatty acid metabolism before and after weight loss.
BACKGROUND Regional differences in meal fat storage may explain the preservation of fat accumulation in obese persons. OBJECTIVE The objective was to determine whether meal fatty acid (FA) metabolism differs by sex and obesity phenotypes before and after weight loss. DESIGN A [(3)H]triolein-containing meal was given to trace meal FA oxidation ((3)H(2)O generation) and adipose tissue uptake ...
متن کاملEffects of exercise before or after meal ingestion on fat balance and postprandial metabolism in overweight men.
It is unclear how timing of exercise relative to meal ingestion influences substrate balance and metabolic responses. The present study aimed to compare the effects of exercise performed before or after breakfast on fat balance and postprandial metabolism. A total of ten sedentary overweight men (aged 28.1 (SEM 10.7) years, BMI 29.0 (SEM 2.8) kg/m2) underwent three trials in random order involv...
متن کاملEffects of meal ingestion on blood pressure and regional hemodynamic responses after exercise.
This study investigated the combined effects of consuming a meal during postexercise hypotension (PEH) on hemodynamics. Nine healthy young male subjects performed each of three trials in random order: 1) cycling at 50% of heart rate reserve for 60 min, 2) oral ingestion of a carbohydrate liquid meal (75 g glucose), or 3) carbohydrate ingestion at 40 min after cycling exercise. Blood pressure, h...
متن کاملGender differences in the regulation of amino acid metabolism.
Exercising men, compared with women, have a greater increase in leucine oxidation but not lysine rate of appearance. The cause for this sexual dimorphism is unknown; however, an inhibition of beta-adrenoreceptor activity has previously been shown to mediate amino acid metabolism (Lamont LS, McCullough AJ, and Kalhan SC. Am J Physiol Endocrinol Metab 268: E910-E916, 1995; Lamont LS, Patel DG, an...
