[Energy-dependent transport of Ca2+ and lipid peroxidation in the sarcoplasmic reticular membranes of rats during hypokinesia].

Thirty-day hypokinesia in Wistar rats did not affect the rate of Ca2+ transport and the activity of Ca-ATPase in light and heavy fractions of sarcoplasmic reticulum of primarily white muscles. As hypokinesia was raised up to 90 days, these indicators increased. The intensity of lipid peroxidation in sarcoplasmic reticulum was lower in hypokinetic animals.
