What type of muscle tissue is directly involved with performing the multiple movement patterns in a dance

routine?

cardiac muscle

skeletal muscle

rigid muscle

contraction

glycogen does not require oxygen to be used by the muscle fibers for contraction

glycogen is broken down to lactic acid and then utilized directly by muscle fibers
