BACKGROUND To date, no physical activity (PA) questionnaires intended for primary care have been compared against a criterion measure of PA and current (2008) aerobic PA recommendations of the American College of Sports Medicine/American Heart Association (ACSM/AHA). AIM This study evaluated preliminary evidence for criterion validity of two brief (<1 min) PA questionnaires with accelerometry...

Abstract Atomic layer deposition (ALD) is a thin-film fabrication technique that has great potential in nanofabrication. Based on its self-limiting surface reactions, ALD excellent conformality, sub-nanometer thickness control, and good process compatibility. These merits promote the industrial research applications of various fields. This article provides an introduction to highlights semicond...

To commemorate a year of celebration for its 50th Annual Meeting in May 2003 and its 50th anniversary as an organization in 2004, the American College of Sports Medicine and Exercise and Sport Sciences Reviews is pleased to publish personal historical perspectives from leading sports medicine and exercise science professionals. This article is the last in a series of articles based on the impac...

Water-soluble organic aerosol (WSOA) in fine particles (PM2.5) collected during wintertime a polluted city (Handan) Northern China was characterized using High-Resolution Time-of-Flight Aerosol Mass Spectrometer (AMS). Through comparing with real-time measurements from collocated Chemical Speciation Monitor (ACSM), we determined that WSOA on average accounts for 29% of total (OA) mass and corre...

Particulate matter was measured in Conroe, Texas (~60 km north of downtown Houston, Texas) during the September 2013 DISCOVER-AQ campaign to determine the sources of particulate matter in the region. The measurement site is influenced by high biogenic emission rates as well as transport of anthropogenic pollutants from the Houston metropolitan area and is therefore an ideal location to study an...

Exercise training is an essential component of pulmonary rehabilitation. However, the cardiopulmonary stress imposed during different modalities of exercise training is not yet known. In the present study, the cardiopulmonary stress of a 12-week exercise training programme in 11 chronic obstructive pulmonary disease (COPD) patients (forced expiratory volume in one second 42+/-12%pred, age 69+/-...

Video games have become increasingly popular among young adults. The purpose of this pilot study was to determine if interactive video/arcade games, requiring physical activity to play, increase the energy expenditure (EE) and heart rate (HR) of young adults enough to elicit a training response. Thirteen male and female participants 26.6 ± 5.7 years of age were in the study. Participants were f...

Despite the importance of randomized, dose-response studies for proper evaluation of effective clinical interventions, there have been no dose-response studies on the effects of exercise amount on abdominal obesity, a major risk factor for metabolic syndrome, diabetes, and cardiovascular disease. One hundred seventy-five sedentary, overweight men and women with mild to moderate dyslipidemia wer...
