BACKGROUND It is unclear whether the common physical activity (PA) intensity descriptors used in PA guidelines worldwide align with the associated percent heart rate maximum method used for prescribing relative PA intensities consistently between sexes, ethnicities, age categories and across body mass index (BMI) classifications. OBJECTIVES The objectives(More)
Obesity is associated with multiple negative health consequences and current weight management guidelines recommend all obese persons to lose weight. However, recent evidence suggests that not all obese persons are negatively affected by their weight and that weight loss does not necessarily always improve health. The purpose of this review is not to(More)
The purpose of this study was to examine force steadiness in three positions of the forearm in young men and women across a variety of force levels. Eight young men and eight young women performed three maximum voluntary contractions (MVCs) in the neutral, supinated, and pronated forearm positions. Viewing a target line on a computer screen, subjects(More)
BACKGROUND To determine whether the relationship between caloric intake, macronutrient intake, and physical activity with obesity has changed over time. METHODS Dietary data from 36,377 U.S. adults from the National Health and Nutrition Survey (NHANES) between 1971 and 2008 was used. Physical activity frequency data was only available in 14,419 adults(More)
This study examined whether sucrose, fructose, aspartame, and saccharin influences the association between obesity and glucose tolerance in 2856 adults from the NHANES III survey. Aspartame intake significantly influenced the association between body mass index (BMI) and glucose tolerance (interaction: P = 0.004), wherein only those reporting aspartame(More)
Fluorescein angiography carries with it a variable incidence of nausea and vomiting. We investigated a method of prophylaxis against this side effect. One hundred patients undergoing fluorescein angiography were pretreated in a double-masked, randomized fashion with either 20 mg of intravenous metoclopramide hydrochloride or an equal volume of normal saline(More)
OBJECTIVE To determine if the association between frequency of leisure-time physical activity and mortality risk differs across adulthood. METHOD 9,249 adults from the NHANES III (1988-1994) were categorized as middle-aged (40-64 years), old (65-79 years) or very old (≥80 years), and as inactive (0 bouts of physical activity/week), lightly active (1-2(More)
BACKGROUND We conducted a study to determine the joint association of physical activity, pharmacologic treatment for hypertension, and the control of blood pressure (BP) on all-cause mortality risk. METHODS The study subjects were 10,665 adults from the Third National Health and Nutrition Examination Survey (NHANES III) and the Continuous NHANES survey(More)
