Descriptive Epidemiology Of Physical Activity In Adolescents, Russell R. Pate, Barbara J. Long, Gregory W. Heath
Descriptive Epidemiology Of Physical Activity In Adolescents, Russell R. Pate, Barbara J. Long, Gregory W. Heath

This paper reviews the descriptive epidemiology of physical activity in adolescents. Large population-based studies were reviewed, along with smaller studies using objective monitoring of physical activity. Estimates showed that adolescents engage in physical activity of any intensity for a mean of one hour per day. Approximately two thirds of males and one quarter of females participate in moderate to vigorous activity for 20 min 3 or more days per week. Activity levels decline with increasing age across adolescence, and this decrease is more marked in females than in males. Comparison of these data to physical activity guidelines for adolescents suggests …

Fibrinolytic Responses To Moderate Intensity Exercise: Comparison Of Physically Active And Inactive Men, Linda M. Szymanski, Russell R. Pate

The purposes of this study were to compare fibrinolytic responses to moderate intensity exercise in physically active and inactive men and during morning and evening exercise. Fourteen physically inactive men (mean age, 34.7 ± 4.0 years) and 12 regularly active men (34.8 ± 4.0 years) performed two exercise sessions, morning and evening, at 50% of maximal oxygen consumption. Tissue plasminogen activator (TPA) andplasminogen activator inhibitor-1 (PAI-1) activity were measured before and after exercise. Data were analyzed using a three-way ANOVA with repeated measures. TPA actively increased with exercise in both groups, although the active group demonstrated greater increases than the …

We do not underestimate the difficulties of legislating on this subject. In addition to the inevitable confrontation with the ethical and moral issues involved, there is the question of the wisdom and effectiveness of regulating a matter so private, yet of such public interest. Legislative consideration of surrogacy may also provide the opportunity to begin to focus on the overall implications of the new reproductive biotechnology- in vitro fertilization, preservation of sperms and eggs, embryo implantation and the like. The problem is how to enjoy the benefits of the technology-especially for infertile couples-while minimizing the risk of abuse. The problem …

Habitual exercise provides protection against fatal coronary heart disease, extends longevity, and enhances quality of life. National surveys show less physical activity in older men and women compared with middle-aged and younger persons; older women are particularly sedentary. Although there are still few longitudinal studies on exercise and physical activity in older individuals, the data support a positive relationship between physical activity and health function in older individuals. The data further show that with regular physical activity, health and fitness are maintained or even increased over time in older individuals. Studies on physical activity requirements for beneficial health effects in …
Humic And Fulvic Acids: Sink Or Source In The Availability Of Metals To The Marine Bivalves Macoma Balthica And Potamocorbula Amurensis?, Alan W. Decho, Samuel N. Luoma
Humic And Fulvic Acids: Sink Or Source In The Availability Of Metals To The Marine Bivalves Macoma Balthica And Potamocorbula Amurensis?, Alan W. Decho, Samuel N. Luoma

Humic acids (HA) and fulvic acids (FA) are common forms of organic matter in marine sediments, and are routinely ingested by deposit- and suspension-feeding animals. These compounds may be a sink for metals, implying that once metals are bound to humic substances they are no longer available to food webs. A series of experiments was conducted to quantitatively examine this premise using 2 estuarine bivalves from San Francisco Bay, USA: the suspension feeder Potarnocorbula arnurensis and the facultative deposit feeder Macoma balthica. HA and FA, isolated from marine sediments, were bound as organic coatings to either hydrous ferric oxides …

Bleach cleansing of injection equipment has been recommended to reduce the risk of human immunodeficiency virus (HIV) transmission associated with the reuse of injection equipment by injecting drug users (IDUs). We evaluated the recall and performance of the most commonly recommended bleach cleansing procedure of two complete fillings of the syringe with bleach, followed by two complete fillings with rinse water, and not putting used bleach and water back into source containers. IDUs were taught this procedure on enrollment in an HIV prevention demonstration project in Dade County, Florida. During follow-up session 6-12 months after initial training, the knowledge and …
