sured at baseline, after a session of exercise, after six weeks of training and after two weeks of deconditioning. Regardless of exercise status, cholesterol concentrations did not change from the baseline measurements at any point in the study. However, platelet aggregation was inhibited after six weeks of exercise, which meant the blood was less likely to form clots. The changes brought about by exercise persisted even after two weeks of deconditioning. Researchers conclude that regular exercise can inhibit the formation of blood clots without altering cholesterol levels.

5:30 p.m. #P150 General public needs stroke awareness education. A statewide sample of 2,512 adults in Michigan indicates a continued need for public education on stroke. One in five respondents could not identify any stroke risk factors and almost one in three were not aware of at least one stroke warning sign. Eighty percent of the respondents could identify at least one risk factor for stroke, and 28 percent were able to identify three risk factors. The most frequently mentioned risk factors named were high blood pressure (32 percent), smoking (29 percent), and physical inactivity (26 percent). When asked about warning signs for stroke, 69 percent were able to identify at least one, and 14 percent could identify three. The most frequently mentioned warning signs were sudden weakness or numbness (46 percent), sudden confusion or trouble speaking (30 percent) and sudden trouble walking or dizziness (24 percent). Most participants (79 percent) reported that once stroke signs were recognized their first action would be to call 9-1-1. A 2001 nationally representative survey conducted by the American Stroke Association found that 41 percent of respondents could not correctly recall any stroke warning sign.
