  • Title: [Reactivity of the sympathetic-adrenal system and physical loading tolerance in multiple exposures to a permanent magnetic field].
    Author: Klimovskaia LD, Kokoreva LV.
    Journal: Kosm Biol Aviakosm Med; 1986; 20(6):70-3. PubMed ID: 3807303.
    Abstract:
    For 30 days rats were exposed daily 3 hrs a day to a constant magnetic field of 1.6 T. The time within which the rats were swimming with a load until they were fatigued was measured and the concentration of catecholamines in blood and adrenals was determined. Two stages of the response to the magnetic field were identified. During the first stage (1-15 days) physical work capacity increased and the reactivity and reserve ability of the sympatho-adrenal system (SAS) grew. During the second stage (30th day and early recovery period) work capacity returned to normal and the SAS reactivity decreased, although the catecholamines stored in the adrenals remained unchanged. These findings indicate that the SAS is involved in mechanisms underlying changes in work capacity and adaptation processes during exposure to a constant magnetic field.
