In the membranes of isolated rat left ventricular mitochondria and microsomal fraction that contained mainly sarcoplasmic reticulum, a two-week submaximal exercise led to an increase in lipid fractions enhancing the viscosity of the membranes and thus modifying their physicochemical properties which affected energy generation and ion transport in myocardiocytes.
