D and PA+D  interventions had larger effects on glucose reduction  than PA alone .
Lifestyle  interventions significantly improved FPG , HbA1c , FI , HOMA-IR , and bodyweight among adults without IGT or diabetes , and might reduce progression of hyperglycemia to type 2 diabetes mellitus
This study systematic ally assessed the effectiveness of lifestyle interventions on glycemic indicators among adults ( ⩾18years ) without IGT or diabetes .
A comparison of methods for analyzing glucose and insulin areas under the curve following nine months of exercise in overweight adults
OBJECTIVE : We examined three methods for calculating the area under the curve ( AUC ) following an oral glucose tolerance test ( OGTT ) in overweight adults prior to and after 9 months of exercise . METHOD : Subjects ( n=27 ) were r and omly assigned to a control  ( CON , n=9 ) or intervention  ( INT , n=18 ) group . INT performed supervised exercise 5 days per week , 45 min per session , at 65 % of heart rate reserve . OGTTs were administered pre- and post-training . Blood was collected during a 75 g OGTT and analyzed for glucose ( GLU ) and insulin ( INS ) concentrations . AUCs were calculated using the incremental , positive incremental , and total AUC methods and the difference scores for pre- and post-training were determined . RESULTS : No differences were observed among the methods for glucose AUC for either group . Significant differences were observed for INT insulin AUC with total AUC ( 1525±3291 µU/1/180 min ) significantly greater than incremental AUC ( 1112±3229 µU/1/180 min ) or positive incremental AUC ( 1085±3195 µU/I/180 min ) . Total insulin AUC was significantly reduced following training for INT , while incremental and positive incremental insulin AUCs showed no change . CONCLUSION : These data suggest that the method of used to calculate AUC may affect the interpretation of whether or not an intervention was effective
