Exercise self-efficacy.

Practitioners have the opportunity to enhance the health of their patients by improving exercise adherence through appropriate exercise prescription and monitoring. Regular physical exercise can prevent or improve many of the chronic health conditions commonly observed in clinical practice. Unfortunately, efforts to help patients adopt an exercise program are often unsuccessful. Researchers have shown that exercise self-efficacy is an important predictor of the adoption and maintenance of exercise behaviors. Self-efficacy is the belief and conviction that one can successfully perform a given activity. Patient compliance with exercise prescriptions is more likely to be successful if exercise self-efficacy is assessed and enhanced. Several questions arise for practitioners who are encouraging their patients to exercise: What are the determinants of exercise self-efficacy? How can exercise self-efficacy be assessed in the clinical setting? What can be done to enhance exercise self-efficacy? This article reviews the research literature addressing these questions and presents tools for assessing self-efficacy and prescribing appropriate exercise in the low-active adult population.

UTAB: a computer database on residues of xenobiotic organic chemicals and heavy metals in plants.

The UTAB Database contains information concerned with the uptake/accumulation, translocation, adhesion, and biotransformation of both xenobiotic organic chemicals and heavy metals by vascular plants. UTAB can be used to estimate the accumulation of chemicals in vegetation and their subsequent movement through the food chain. The database contains actual data from papers in the published literature dating from 1926 for organic chemicals and from 1976 for heavy metals. At present the database is comprised of more than 37,000 records pertaining to 900 different organic chemicals, 21 heavy metals, and over 350 plant species. Each record contains information on a single combination of species, chemical, and dose. Other information includes the application and destination sites, amount accumulated, rates of uptake or translocation, products and sites of biotransformation, experimental condition parameters, and the source paper. Thus, the database can be used to quickly obtain specific data pertaining to a chemical, plant species, mine spoil, etc. or it can be used for the comparative analysis of a set of data pertaining to groups of chemicals and plants.
