Influence of blood pressure elevations by isometric exercise on pain perception in women

Contralateral Attenuation of Pain After Short-Duration Submaximal Isometric Exercise

“…This is a possibility; however, previous research with the pressure device used in this study showed no significant changes in pain perception with repeated applications. 12,28 Second, it was difficult to blind the tester so behavioral artifacts (eg, demand characteristics) may be a possible limitation of this study. To minimize potential behavioral artifacts, we used a naïve tester (ie, trained student not familiar with the exercise and pain literature) who used scripted instructional sets.…”

“…20 In addition, findings from previous controlled experiments with the pressure device showed no significant change in pain perception with repeated applications. 12,28 Testing was performed by a "naïve" experimenter (ie, trained student not familiar with the exercise and pain literature) who used scripted instructional sets in order to minimize potential behavioral artifacts (eg, demand characteristics).…”

Men Report Greater Pain Relief Following Sustained Static Contractions Than Women When Matched for Baseline Pain

“…Additional physiological measurements that have been associated with pain perception and EIH were studied to provide insight into possible mechanisms for any sex differences in the pain response following exercise. These measurements included the following: mean arterial pressure (MAP; Umeda, Newcomb, & Koltyn, 2009), heart rate (Borg, Ljunggren, & Ceci, 1985), rating of perceived exertion (RPE) (Borg, 1985), and anxiety (Willer, Dehen, & Cambier, 1981).…”

Chronic Pain and Exercise: Studies on pain intensity, biochemistry, adherence and attitudes

“…There are also other possible physiological mechanisms earlier proposed to be involved in pain inhibition as a result of PA&E, for example conditioned pain modulation [230,231], blood pressure [156][157][158], and the endocannabinoid system [232][233][234]. However, these physiological mechanisms are not examined in this thesis.…”

“…The pain inhibitory effects has been proposed to derive from descending pain modulating pathways in the central nervous system, as well as from the release of endogenous endorphins [153][154][155]. In addition, associations between blood pressure and pain inhibition has been noted, although the interactions between blood pressure and pain inhibition not is entirely understood [156][157][158][159].…”
