Abstract:
Earthing is a direct contact with the earth or indirect with the use of a metal conductor. The earthing eliminates potentials on body and influences physiological processes. We examined whether the earthing influences glucose, lactate and bilirubin concentration in exercise and relaxation. In a double-blind, crossover study, 42 participants divided into two groups basing on their utilization oxygen were earthed during exercise and recovery sessions. In the first experiment group A was earthed, group B unearthed, in the second experiment in the opposite way. The mean weight of participants in group A was 77, 1 and 72,8 in group B. For the earthed group, after 15min of exertion we observed a rise, after 30min decrease in glucose concentration, and in the 40min of relaxation a secondary rise. For unearthed participants, we noted a decrease in glucose concentration after 15min of exertion and a gradual rise later on. The baseline concentration of bilirubin was higher after earthing (p=0,006) in group A (0,91±0,50) than in group B (0,55±0,22) and without earthing the difference was not significant (p=0,13) in group A (0,85±0,46) and in group B (0,65±0,35). Earthing caused elevation of bilirubin concentration in group A and reduction in group B both in exercise and relaxation. It indicates that earthing modulates metabolism of erythrocytes and adjusts it to level of proper body mass as a functional dielectric. Earthing during exercise helps the training organism to mobilize plasma glucose for its muscular uptake and facilities more effective utilization in energetic processes.
