Abstract/OtherAbstract:
This study compared the effects of resistance exercise (RE) intensities on blood glucose (GLUC) of individuals without (ND) and with type-2 diabetes (T2D). Nine individuals with T2D and ten ND performed: 1) RE-circuit at 23% of one repetition maximum (1RM) (RE_L); 2) RE-circuit at 43%1RM (RE_M); and 3) control session (CON). Blood lactate (LAC) and GLUC were measured before, during and post-interventions. Double product (DP) and rate of perceived exertion (RPE) were recorded. The area under the curve (AUC) revealed the effects of RE-circuits in reducing GLUC in individuals with T2D (RE_L: 12556±3269 vs. RE_M: 13433±3054 vs. CON: 14576±3922 mg.dL.145min; p<0.05) with a lower AUC of GLUC in RE_L in comparison to RE_M. Similarly, for ND the RE_L reduced the AUC of GLUC when compared to RE_M and CON (RE_L:10943±956 vs. RE_M:12156±1062 vs. CON:11498±882 mg.dL.145min; p<0.05). The AUC of GLUC was higher for T2D compared to ND on CON condition (p=0.02). However, after RE-circuits the difference between groups for AUC of GLUC was abolished. The RE_M for T2D was more stressful when compared to RE_L for LAC (CON:1.3±0.5 vs. RE_L:5.5±1.5 vs. RE_M:6.8±1.3 mmol·L; p<0.05), DP (CON: 8415±1223 vs. RE_L: 15980±2007 vs. RE_M: 18047±3693 mmHg.bpm; p<0.05) and RPE (RE_L: 11±2 vs. RE_M: 13±2 Borg-Scale; p<0.05). We concluded that RE_L and RE_M were effective in reducing GLUC for individuals with T2D, with lower cardiovascular-metabolic and perceptual stress being observed for RE_L. These data suggest that acute resistance exercise sessions at light or moderate intensities are effective for controlling blood glucose in individuals with T2D.
