Effect of Aerobic and Resistance Training on Resistin & Insulin Levels in Women with Gestational Diabetes

The purpose of study was to determine the effect of aerobic and resistance training on resistin, fasting blood sugar, insulin and insulin resistance in women with gestational diabetes mellitus. For this purpose, 34 women with gestational diabetes voluntarily participated which were selected from the available sampling pool. The subjects were simple random assigned in 3 groups. 12 subjects (age 28.92 ± 3.60 years) participated in an aerobic training group (3 days/week, 30-45 min/day, 50-70%maximum heart rate), 11subject (age 30.27 ± 4.14 years) participated in a resistance training group (3 days/week, 2-3 set of 15 repetition, 50-70%maximum heart rate and Rating of perceived exertion), and 11 subjects (age 29.18 ± 4.23 years) were in control group who did not participate in any exercise program during the study period. Blood samples were collected in the pre-test and post-test to assess the level of blood sugar, insulin and resistin. ELISA method was used to measure resistin. Paired samples T Test results showed that resistance training leads to significant decrease in fasting blood sugar (P=0.012) and insignificant reduction in aerobic group (P=0.31), in training groups was observed insignificant changes in resistin, insulin levels, insulin resistance and insulin sensitivity. The results of covariance analysis indicated a significant difference in decreased insulin resistance index (P=0.008) and increased insulin plasma levels (P=0.031), and insulin sensitivity between groups. While variance analysis did not show significant difference in resistin levels in groups. It seems likely resistance training is more effective in compression to aerobic training in reducing fasting glucose levels and insulin resistance in women with gestational diabetes.
