Main outcome of study (acc. to author)

The data demonstrated no influence of this low frequency magnetic field on the level of important energy metabolites in rat skeletal muscle. It is concluded that neither repeated exposure nor the acute exposure of rats to the sinusoidal magnetic field of given parameters has any important influence on the energy state of the skeletal muscle.
