we found 1 ) a progressive increase in insulin concentrations reaching 1,092 +/- 135 microu/ml with increasing glucose levels , 2 ) linear relationships between glucose concentrations and concentrations of c-peptide ( r = 0.931 +/- 0.008 ) and proinsulin ( r = 0.952 +/- 0.009 ) ,3 ) increased glucose oxidation with increasing glucose uptake , 4 ) increased plasma norepinephrine , o2 uptake , and beta-hydroxybutyrate at greater than or equal to 20 mm glucose , and 5 ) no change in beta-cell response or glucose-induced thermogenesis after one bout of exercise despite no compensating changes in plasma concentrations of hormones or metabolites .
