Background: Regulation of core body temperature (Tc) can cause significant cardiovascular strain, leading to impaired performance, incapacitation and occupational hazard during work in the heat. Where continuous Tc and heart rate (HR) monitoring is not possible (e.g. during firefighting or on military operations), safer working could result from intermittent sampling of an integrated measure of physiological strain.Aims: To assess the relationship betwee...

We have previously reported that exercise at high altitude (HA) led to a significant increase in brain natriuretic peptide (BNP) levels. In contrast two other publications have reported no change in resting BNP at HA. We therefore measured BNP and Lake Louise (LL) Acute Mountain Sickness (AMS) scores in a further 20 subjects at rest in Kathmandu (Kat; 1300 m); and following exercise and at rest at 4270 m and 5150 m. Compared with the baseline BNP level at Kat (9.2+/−2 pg...
