homeostasis/metabolism
• in spite of increased skeletal muscle glycogen level, mice reach exhaustion earlier than wild-type controls in a treadmill endurance test
• mice cover a shorter distance than wild-type controls in a treadmill endurance test
• under resting conditions, adult mice show a 7-fold increase in skeletal muscle glycogen level relative to wild-type controls
• at the point of exhaustion following treadmill exercise, mice show a greater reduction of glycogen content in skeletal muscle than wild-type controls

muscle
• under resting conditions, adult mice show a 7-fold increase in skeletal muscle glycogen level relative to wild-type controls

behavior/neurological
• in spite of increased skeletal muscle glycogen level, mice reach exhaustion earlier than wild-type controls in a treadmill endurance test
• mice cover a shorter distance than wild-type controls in a treadmill endurance test

cellular
• adult soleus muscle exhibits lower oxygen consumption affecting all mitochondrial states relative to wild-type muscle
