Many obese elderly persons have impaired physical function associated with an increased chronic inflammatory response. We evaluated 12 wk of exercise (aerobic and resistance) or 12 wk of weight loss (approximately 7% reduction) on skeletal muscle mRNAs for toll-like receptor-4 (TLR-4), mechanogrowth factor (MGF), TNF-alpha, and IL-6 in 16 obese ...

BACKGROUND: Whether alterations in the sympathoadrenal system contribute to obesity or, rather, are consequences of it, is an unresolved issue. OBJECTIVE: We hypothesized that the sympathoadrenal system plays a predictive role in the development of body fat. DESIGN: At entry, arterial plasma epinephrine and norepinephrine concentrations were measured in 99 ...
