Chronic blood pressure (BP) reductions resulting from exercise interventions have been linked to an acute vascular response, post‐exercise hypotension (PEH). PEH has traditionally been stimulated using continuous aerobic exercise bouts. The use of isometric handgrip (IHG) contractions to elicit PEH is an emerging area. The present research investigated PEH in response to both ergometer cycling and bilateral IHG contractions in post‐menopausal women, a demographic of imperative concern. Women completed an acclimatization session followed by four experimental sessions; two using IHG as a stimulus and two using ergometer cycling as a stimulus. Pre‐ and post‐exercise BP were determined using an automated sphygmomanometer (BPTru). Participants were 5 post‐menopausal women with an average resting BP of 117.8 ± 1.8 / 79.9 ± 1.7. In contrast to expectation, both of the exercise stimuli induced acute increases in BP. Aerobic stimuli induced increases of 2.1 ± 0.6 / 3.2 ± 0.4. IHG stimuli induced changes of 3.9 ± 0.7 / 3.9 ± 0.5. Further exploration of this relationship is required to determine the exercise protocols which will elicit PEH in this specific population of post‐menopausal women. This information will be valuable in prescribing acute exercise bouts for blood pressure control in this at‐risk demographic.
