摘要
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 (aged 69 +/- 4 years) resting in extreme heat (40 degrees C). While ISPC increased 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.
