It is the position of the American Dietetic Association, Dietitians of Canada, and the American College of Sports Medicine that physical activity, athletic performance, and recovery from exercise are enhanced by optimal nutrition. These organizations recommend appropriate selection of food and fluids, timing of intake, and supplement choices for optimal(More)
OBJECTIVE Blood pressure (BP) is immediately lowered after a session of dynamic exercise, e.g. postexercise hypotension (PEH). The optimal exercise intensity needed to evoke PEH has not been established. We examined the effect of light (LITE) and moderate (MOD) exercise intensity on PEH. DESIGN Subjects were 49 men (mean +/- SEM, 43.8 +/- 1.4 years) with(More)
Recent trends in weight loss diets have led to a substantial increase in protein intake by individuals. As a result, the safety of habitually consuming dietary protein in excess of recommended intakes has been questioned. In particular, there is concern that high protein intake may promote renal damage by chronically increasing glomerular pressure and(More)
Although health initiatives promote increased physical activity in children, the physiologic outcomes have not been well characterized. This investigation examined the effects of programmed aerobic exercise on protein metabolism in children (n = 7; mean +/- SEM: 9.14 +/- 0.46 y old; weight, 32.1 +/- 1.6 kg; height, 138 +/- 2.5 cm; and body mass index, 16.21(More)
Osteoporosis and sarcopenia are degenerative diseases frequently associated with aging. The loss of bone and muscle results in significant morbidity, so preventing or attenuating osteoporosis and sarcopenia is an important public health goal. Dietary protein is crucial for development of bone and muscle, and recent evidence suggests that increasing dietary(More)
PURPOSE Public health initiatives promote increased physical activity in children. More specifically, resistance training has recently received attention as an important component of youth fitness programs. The study examined the effect of this mode of exercise on protein utilization in young boys and girls. METHODS Healthy children (N = 11, 8.6 +/- 1.1(More)
BACKGROUND Dietary calcium intake and the renin angiotensin system (RAS) regulate blood pressure (BP) by modulating calcium homeostasis. Despite similar BP regulatory effects, the influence of dietary calcium intake alone and combined with RAS polymorphisms on the BP response following acute aerobic exercise (i.e., postexercise hypotension) has not been(More)
To date, few studies have characterized the influence of energy deprivation on direct measures of skeletal muscle protein turnover. In this investigation, we characterized the effect of an acute, moderate energy deficit (10 d) on mixed muscle fractional synthetic rate (FSR) and associated intracellular signaling proteins in physically active adults. Eight(More)
OBJECTIVE To characterize the relationship of subclinical and clinical eating disorders to HbA1c values in women with IDDM. RESEARCH DESIGN AND METHODS Ninety women with IDDM (18-46 years of age) were recruited from diabetes clinics throughout Connecticut and Massachusetts. Subjects were categorized into one of three groups according to the Diagnostic(More)
PURPOSE OF REVIEW Whereas diet and exercise have been shown to influence whole-body protein utilization, little is known about the impact of these factors on skeletal-muscle protein turnover. We highlight the role of dietary protein in modulating skeletal-muscle protein turnover in response to endurance exercise. Effects of endurance exercise on(More)
