Obesity in adolescence increases the risk for early adult cardiovascular disease. We recently showed that 6 months of diet, exercise, and metformin resulted in reductions in adiposity and that diet/exercise alone reduced proinflammatory factors and intrahepatic fat in pubertal children with uncomplicated obesity. The purpose of the present study was ...

A maximal-exercise RER (RER(max) ≥ 1.10 is commonly used as a criterion to determine whether a "true" maximal oxygen uptake (V˙O(2max)) has been attained during maximal-effort exercise testing. Because RER(max) is heavily influenced by CO2 production from acid buffering during maximal exercise, we postulated that dietary acid load, which affects ...

Standards for estimating maximal HR are important when interpreting the adequacy of physiologic stress during exercise testing, assessing chronotropic response, and prescribing an exercise training regimen. The equation 220 - age is used to estimate maximum HR; however, it overestimates measured maximal HR in patients taking β-adrenergic blockade (βB) therapy. ...

An RS4-type resistant starch is a chemically modified starch that shows reduced availability in comparison to the corresponding unmodified starch. Hydroxypropylated distarch phosphate (HDP) is an RS4-type resistant starch that increases energy expenditure and prevents high-fat diet-induced obesity through increased hepatic fatty acid oxidation. The aim of this study was ...
