Effect of endurance, resistance and concurrent training on sICAM-1 levels and insulin resistance in inactive women

This study examines the effect of endurance, resistance and concurrent training on serum sICAM-1 levels and insulin resistance index in inactive women.44 healthy women with an average age of 20.2±1.6 years and BMI 20.8±3 kg/m2 divided into four groups: endurance, resistance, concurrent and control groups (each group, n=11). Training was conducted for six weeks and three times a week. Endurance training consists of aerobic blocks (60 to 75 percent of maximum heart rate). Resistance training was carried out (60 to 75 percent of one repetition maximum). In concurrent training program, subjects performed one session of resistance training and in the next session they did the endurance training. Blood samples were taken 36 hours before and again 36 hours after the end of training. The findings of this study using ANOVA with repeated measure showed that the levels of sICAM-1 in resistance (P>0.0001) and concurrent (P>0.0001) groups had a significant reduction, while in the endurance group this reduction was not significant. The changes in insulin and insulin resistance index in none of the groups was not significant. But, fasting glucose levels drop significantly in the concurrent group (p=0.01), while each groups was unchanged in the other. Furthermore, in connection with any of the variables, no significant changes were observed between groups. It seems that concurrent training have more impact on levels of intercellular adhesion molecule and insulin resistance index in healthy untrained women and to improve these indicators,
