Energy Expenditure of Standing Compared to Sitting While Conducting Office Tasks.

Objectives This study aimed to investigate the energy expenditure of common office-based tasks. The objectives were to: (a) test the classification of tasks as sedentary or light-intensity physical activity and (b) compare the energy expenditure of tasks under two postural conditions (sitting and standing). Background The sedentary nature of office work has been highlighted as a health risk, and strategies to reduce sedentary behavior at work have been developed.

Cardiac event rate in a lifestyle modification program for patients with chronic coronary artery disease.

Background: Several clinical trials have shown that intensive lifestyle modification programs have a significant impact on cardiovascular risk factors.

Hypothesis: This paper is a retrospective analysis to determine the effect of participation in a 2-year lifestyle management program on long-term clinical outcome in patients outside the setting of a clinical trial.

Methods: Patients with angiographically confirmed coronary artery disease (CAD) enrolled in a 2-year program of exercise training, dietary counseling, stress management, and therapeutic education.
