This ebook tells about Research has indicated that acute exercise can alter pain perception. However, it is currently unclear whether men and women differ in the hypoalgesic responses following exercise, and whether elevations in blood pressure (BP) induced by exercise influences pain perception following exercise in a systematic manner. Thus, the purpose of this study was to examine exercise-induced hypoalgesia following isometric exercise in men and women, and whether different magnitudes of BP elevations induced by isometric exercise systematically influenced pain perception. Twenty-five healthy men and 25 healthy women (mean age = 23 yrs +/- 5) completed one baseline session and three isometric exercise sessions consisting of squeezing a hand dynamometer at 25% MVC for 1 minute, 3 minutes, and 5 minutes with their dominant hand. A pressure stimulus was applied to the forefinger of the exercised hand for 2 minutes before and following isometric exercise. The participants pressed a button when the sensation changed from non-painful to slightly painful indicating pain thresholds (PT), and rated the intensity (PRI) and the unpleasantness (PRU) of the sensation every 30 seconds during exposure to the pressure stimulus using pain rating scales. BP was assessed every 30 seconds during exposure to the pressure stimulus and during isometric exercise. Results indicated that BP was significantly elevated by isometric exercise in a dose-response manner in men and women, with longer durations of isometric exercise producing greater elevations in BP compared to shorter durations of isometric exercise (p
