obsolete positive regulation of ryanodine-sensitive calcium-release channel activity (obsolete GO:0060316)
OBSOLETE. Any process that increases the activity of a ryanodine-sensitive calcium-release channel. The ryanodine-sensitive calcium-release channel catalyzes the transmembrane transfer of a calcium ion by a channel that opens when a ryanodine class ligand has been bound by the channel complex or one of its constituent parts.
