This study examined the effect of exercise training without weight loss on high-density lipoprotein (HDL) metabolism in overweight men. We evaluated HDL metabolism using 125I-radiolabeled autologous HDL in 17 overweight men aged 40 +/- 7 years (mean +/- SD) before and after 1 year of exercise training. Subjects consumed defined diets in a metabolic kitchen(More)
High-density lipoprotein (HDL) metabolism was studied in eight sedentary men before and after 14 and 32-48 weeks of exercise training. Subjects rode stationary bicycles 1 hour daily, 5 days each week for 14 weeks (n = 8), and 4 days each week thereafter for a total of 32-48 weeks (n = 7) of training. HDL metabolism was assessed with 125I-radiolabeled(More)
Oral anabolic steroids produce striking reductions in serum concentrations of high-density lipoprotein (HDL) cholesterol. We hypothesized that this effect related to their route of administration and was unrelated to their androgenic potency. We administered oral stanozolol (6 mg/d) or supraphysiological doses of intramuscular testosterone enanthate (200(More)
We compared the clearance rate (K2) of plasma triglycerides (TG) following the intravenous (IV) infusion of a fat emulsion in 13 male endurance athletes (age 33 +/- 5.6 years, mean +/- SD) and 12 sedentary men (33 +/- 5.6 years). The athletes had lower fasting triglycerides (TG) (75 +/- 30.4 mg/dL v 125 +/- 52.5 mg/dL) and higher high-density lipoprotein(More)
Acute reductions in triglycerides and low density lipoprotein (LDL) cholesterol concentrations have been demonstrated in endurance athletes after prolonged exercise. To determine if similar changes occur in untrained subjects and to determine the duration of exercise necessary for such changes, we measured serum lipids and lipoproteins in 10 sedentary men(More)
Serum lipids are known to vary during the menstrual cycle. To determine if changes in plasma volume contribute to this effect, we determined serum lipids, lipoproteins, and estimated changes in plasma volume in 18 premenopausal women at the start of and at 5-day intervals after menstruation. Eleven men served as a comparison group. Changes in plasma volume(More)
We sought to determine the optimal dose of heparin for evaluating the activities of lipoprotein lipase (LPLA) and hepatic triglyceride hydrolase (HTGLA) in postheparin plasma. Nine physically active and ten sedentary men (age 30 +/- 5 yr, mean +/- SD) received 30, 50, 75, and 100 IU/kg of heparin in random order during a 2-week period. Based on all the(More)
The metabolism and toxicity of the ubiquitous plasticizer, bis-(2-ethylhexyl) phthalate (DEHP), and its principal metabolite, mono-(2-ethylhexyl) phthalate (MEHP), have been extensively investigated. In an attempt to understand their disposition in man, we studied the in vitro serum protein-binding characteristics of these compounds, using(More)
We examined the effects on blood pressure, plasma lipoproteins, and platelet function when marine oil supplements (rich in n-3 fatty acids) or vegetable oil supplements (rich in n-6 fatty acids) were added to the usual diets of patients with mild essential hypertension. In a randomized, double-blind, parallel-group study, patients received 50 g of either(More)
Blood was drawn from twenty normal hospital employees after a 12-14 hr fast (9:30 AM), and at 4 hr (1:30 PM) and 7 hr (4:30 PM) thereafter while test subjects consumed their habitual diet. Absorptive chylomicronemia was reflected in average triglyceride increases of 30% and 53% at 4 hr and 7 hr, respectively. No significant changes in total (< 1%) and high(More)
