The effects of stability ball training on spinal stability in sedentary individuals.

Stability ball training (SBT) is believed to improve spinal stability (SS) and could reduce the risk of back pain in sedentary individuals. The purpose of this study was to examine the effects of SBT on SS. Twenty sedentary individuals were randomly assigned to either an experimental group that performed SBT twice per week for 10 weeks or to a control group.

Increasing the health promotive capacity of human environments.

This article offers an integration of two different perspectives on health promotion research and practice: one emphasizing the concept of community capacity for health improvement and the other focusing on the notion of health supportive environments. These two approaches generally have emphasized different kinds of community assets for health promotion. Specifically, community capacity research has focused on the cultivation of human resources (e.

Should the threshold limit value for power frequency (60 Hz) magnetic fields be changed? Perceptions among scientists and other risk experts.

Over the past few years several studies have raised questions about childhood cancer and exposure to electric and magnetic fields (EMFs). Reports by the National Academy of Sciences and the National Cancer Institute concluded that there is no clear, convincing evidence that exposure to electric power lines and electric power appliances is a threat to human health, whereas the National Institute of Environmental Health Sciences concluded that there is weak evidence that EMF exposure may be a leukemia hazard. Based on the conflicting agency reports on EMF, what do experts in the field of bioelectromagnetics believe regarding the effectiveness of the American Conference of Governmental Industrial Hygienists (ACGIH) guidelines? Surveys were sent to 163 participants at the 1997 annual Department of Energy Contractors meeting on Electric and Magnetic Fields.

Attitudes about electric and magnetic fields: do scientists and other risk experts perceive risk similarly?

Wherever there is electric power, 60-hertz (60-Hz) electric and magnetic fields (EMFs) are produced. Recently, conflicting reports have been published by government agencies about adverse health effects linked to EMFs. This paper seeks to identify the demographic and job-related factors that may explain differences among experts' perception of risk attributable to EMFs.
