Key result
Changing posture from sitting to standing altered cardiovascular oscillations, and 0.10 Hz thermal stimulation entrained heart rate oscillations in both sitting and standing subjects (p<0.05).
Why the study?
Does posture affect thermally stimulated cardiovascular oscillations in young men?
Population
5 fit young men, aged 20-21 years
Comparison
Increased gravitational stress and thermal skin… vs Sitting position and prestimulus values

Does posture affect thermally stimulated cardiovascular oscillations in young men?
p-value: p=<0.05
Postural changes and thermal stimulation interact to affect cardiovascular oscillations, suggesting coupling between thermoregulatory and reflex activities.
Lindqvist et al. (1990) conducted an observational in Healthy volunteers (n=5). Posture change (sitting to standing) and thermal skin stimulation vs. Sitting position and prestimulus values was evaluated on Cardiovascular changes including heart rate, heart rate variability, and skin blood flow (p=<0.05). Changing posture from sitting to standing altered cardiovascular oscillations, and 0.10 Hz thermal stimulation entrained heart rate oscillations in both sitting and standing subjects (p<0.05).
