Abstract
BACKGROUND: Post-exercise hypotension (PEH) is a well-documented phenomenon, but the impact of body position on its magnitude remains incompletely understood. This relationship between body position and post-exercise hypotension is critical, not only for recovery, but for populations with conditions like hypertension or heart disease. PURPOSE This study aims to determine if a post-exercise posture alters the post-exercise hypotension response. The findings may have implications for exercise prescriptions and clinical recommendations for optimizing cardiovascular health. METHODS: Ten participants aged 18-30 years will complete two blood pressure and equipment familiarizationv visits, in addition to four randomized conditions: control-no exercise (CON), seated post-exercise (SIT), supine post-exercise (SUPINE) and standing post-exercise (STAND). Each visit following the familiarization visits will involve pre-exercise measurements, followed by a high-intensity interval exercise session (4 x 4 protocol at 80-95% VO2max). Post-exercise measurements of brachial and central blood pressure, pulse wave analysis, cardiac output, and systemic vascular resistance will be taken every 5 minutes for 60 minutes following exercise or rest. RESULTS: Ten participants, 5 male and 5 female, aged 23 ± 7.2 yr. with an average BMI of 24 ± 3.9 kg/m2 completed this study. There were no baseline group differences for any variable. There were significant group differences in post-exercise HR between all groups (CON: 59.5 ± 2.9 bpm, SUPINE: 72.4 ± 2.9 bpm, SIT: 82.8 ± 2.9 bpm, STAND: 90.2 ± 2.9 bpm, pCONCLUSION: Body positioning may play a significant role in the PEH response and should be carefully considered when conducting PEH research.
