The improved glycaemic control , which was only seen in the IWT group , was consistent with IWT-induced increases in insulin sensitivity index ( 49.8 14.6 % ; p < 0.001 ) , peripheral glucose disposal ( 14.5 4.9 % ; p < 0.05 ) and DI ( 66.2 21.8 % ; p < 0.001 ) , with no changes in the CWT or CON group .
