Similar effects also appeared in SBP and DBP categories regardless of follow-up duration .
PA+D interventions had larger improvement effects on CVD risk factors than PA alone interventions .
In adults without IGT or diabetes , lifestyle interventions result ed in significant improvements in SBP , DBP , TC , LDL-C , HDL-C , and TG , and might further reduce CVD risk
Structured lifestyle interventions can reduce diabetes incidence and cardiovascular disease ( CVD ) risk among persons with impaired glucose tolerance ( IGT ) , but it is unclear whether they should be implemented among persons without IGT .
We conducted a systematic review and meta-analyses to assess the effectiveness of lifestyle interventions on CVD risk among adults without IGT or diabetes .
Aerobic exercise training conserves insulin sensitivity for 1 yr following weight loss in overweight women.
The objectives of this study were to 1 ) identify the independent effects of exercise ( aerobic or resistance training ) and weight loss on whole body insulin sensitivity and 2 ) determine if aerobic or resistance training would be more successful for maintaining improved whole body insulin sensitivity 1 yr following weight loss . Subjects were 97 healthy , premenopausal women , body mass index ( BMI ) 27 - 30 kg/m(2 ) . Following r and omized assignment to one of three groups , diet only , diet + aerobic , or diet + resistance training until a BMI < 25 kg/m(2 ) was achieved , body composition , fat distribution , and whole body insulin sensitivity were determined at baseline , in the weight reduced state , and at 1-yr follow up . The whole body insulin sensitivity index ( S(I ) ) was determined using a frequently sample d intravenous glucose tolerance test . Results of repeated- measures ANOVA indicated a significant improvement in S(I ) following weight loss . However , there were no group or group × time interactions . At 1-yr follow up , there were no significant time or group interactions for S(I ; ) however , there was a significant group × time interaction for S(I ) . Post hoc analysis revealed that women in the aerobic training group showed a significant increased S(I ) from weight reduced to 1-yr follow up ( P < 0.05 ) , which was independent of intra-abdominal adipose tissue and % fat . No significant differences in S(I ) from weight reduced to 1-yr follow up were observed for diet only or diet + resistance groups . Additionally , multiple linear regression analysis revealed that change in whole body insulin sensitivity from baseline to 1-yr follow up was independently associated with the change in Vo(2max ) from baseline to 1-yr follow up ( P < 0.05 ) . These results suggest that long-term aerobic exercise training may conserve improvements in S(I ) following weight loss and that maintaining cardiovascular fitness following weight loss may be important for maintaining improvements in S(I )
