Intermittent sequential pneumatic compression does not enhance whole-body heat loss in elderly adults during extreme heat exposure.Appl Physiol Nutr Metab 2019AP
Lower-limb intermittent sequential pneumatic compression (ISPC) improves circulation and vascular function in elderly adults. We evaluated the hypothesis that ISPC would also augment whole-body heat loss (WBHL) in elderly adults (69±4 years) resting in extreme heat (40°C). While ISPC augmented mean arterial pressure (91±9 mmHg) relative to no-ISPC (83±5 mmHg; P=0.013) at the end of the exposure, no influence on WBHL was observed (81±7 and 86±11 W for ISPC and no-ISPC respectively, P=0.310). Novelty: • When assessed in elderly adults during an extreme heat exposure, intermittent sequential pneumatic compression augmented mean arterial pressure, but did not enhance whole-body heat loss.
