Relationship between cardiac autonomic activity following upper body exercise and total body water in men of different ages

Abstract

Purpose: Adropin a secreted protein is encoded by a gene Energy Homeostasis Associated (Enho) expressed in different tissues. The purpose of this study was to investigate the effect of eight weeks of resistance training on adropin plasma level and insulin resistance index in overweight men.Methods: For this purpose, 24 volunteer overweight men (age 25.3 ± 5.1, body mass index 27.74 ± 2.54) were randomly divided into two groups of training and control. The training group held a resistance program for eight weeks, three sessions in each. The resistance program included three sets of 10 repetitions with 65, 75 and 85% 1RM for eight movements. One minute rest time was considered between sets and movements. Before and after the training period, the interested indices were measured by standard methods.Results: ANOVA with Repeated measure test showed that there was a significant difference between the changes in adropin, glucose, insulin and insulin resistance (P = 0.001), also showed that adropin, glucose, insulin and insulin resistance (P = 0.001) are significant only in the training group.Conclusion: It seems that this kind of resistance training has been able to stimulate adropin due to the sufficient duration and intensity of the activity.
