- Abstract:
- Out of similar to 100 mu L of capillary blood of both office and production workers with moderate physical workload, ionized magnesium, ionized potassium, ionized calcium, pH, pCO(2), pO(2), O-2 saturation and lactate have been analyzed before and after a 5 minute's concentration test (Shapiro test), whereby observing correlative behavior of the trias pH-pCO(2) and ion. Mg was of special interest. It turned out that the vast majority of participants showed alkaline blood due to overcompensatory breathing, which binds higher quantities of Mg and oxygen but does not release them readily. Although severe physical loads are absent, the participants' metabolism is nevertheless increased and increasable by mental loads, but the alkaline binding of oxygen and electrolytes seems to prevent their adequate liberation. Moreover, it could be demonstrated that office workers are answering with about double the stress to a mental load than production workers, whereby increased breathing increases the average pH only in production workers. The greater efforts of office workers remain mostly ineffective. Our results show that jobs without appreciable physical workload may imminently lead to bottlenecks in oxygen and Mg supply, which can be overcome by regular sports and Mg substitution.
