Abstract

Abstract : Objective: Mostly sedentary occupations combined with mental stress enhance systolic blood pressure and heart frequency (HF) along with mostly unnoticed increased breathing frequency. We wondered whether alsó congress attendees would be subjected to similar inconveniences and whether an enforced leg movement would have comparable effects to sports or breaks. Design and method: After about 90 minutes of lecture attending, 24 members of the congress went into an adjoing room, where 10 minutes of enforced foot and leg movement was applied by a leg - moving device (wobbler) with frequency of 6, 7 Hz while sitting on a chair. Before and after treatment systolic and diastolic blood pressure as well as heart frequency were determined by a Beurer / Ulm system. Moreover, 100 microliters of blood were taken from the fingertrip for electrode - deternination of pH and pCO2 by a NOVA biochemical device, widely used in IUCs. For data evaluation a subgroup above systolic blood pressure 140 mmHg was juxta positioned to the total participants. Results: The most obvious difference in the group averages is the significant fall of systolic blood pressure in the > 140 group from 155 mmHg to 134 mmHg within 10 minutes. Although there were no significant correlations between systolic blood pressure and pH, pH and pCO2 in the all participants group (in both p < 0.05), there were significant differences in the >140 group. After treatment the lowest systolic blood pressure went along with the lowest pH, while pCO2 loss led overcompensatory pH increase. Thus, even the comparatively calm atmosphere at a scientific congress seems to induce a certain amount of tension to participants, which expresses itself by increased systolic blood pressure in an appreciable number of attendees and increasingly alkaline pH. An application of a device, by which an allegedly natural movement of the feet and the lower legs is induced, effects a significant and substantial decrease of systolic blood pressure of 21 mmHg within only 10 minutes. Conclusions: These mechanisms could be of further advantage in the treatment of hypertension and leg movement (restless legs or diabetic legs).
