Effects of electrical stimulation on the activity of hexokinase in the medial gastrocnemius muscle of aged rats after hindlimb suspension.
1. The activity of the enzyme Hexokinase (E.C. 2.7.1.1.) has been measured after a 21 day period of hindlimb suspension and a 14 day period of recovery with or without electrical stimulation in the old rat Medial Gastrocnemius muscle divided in its white and red parts. 2. After suspension, the activity of the enzyme increased in both parts of the muscle and returned near its control value more rapidly in the red part of the muscle when electrical stimulation was applied.
