A few findings are available about novel<br />insulin resistance indices. The purpose of this study was to investigateeffect of endurance training on novel<br />insulin resistance indices and some of cardio metabolic risk factors in inactive lean men. Methodology:In a<br />semi-experimental study, twenty inactive lean men were randomly placed at two groups: endurance training<br />(n=10, 21.2±2.2 yr) and control (n=10, 21.4±2.7 yr). General characteristics of subjects, Adiponectin-Resistin<br />(AR), homeostasis model assessment-Adiponectin (HOMA-AD) and insulin resistance index(IRAR), blood<br />pressure, and lipid profile were assessed before and after training. Endurance training consisted of twelve<br />weeks pedaling on ergometer cycle(3 sessions per week, intensity 60-70% of reserved heart rate, duration of<br />each session 20-40 min). Data analyzed by paired- and independent-t tests. Statistical significance was<br />accepted at P<0.05. Results:After the training period, HOMA-AD (P=0.043), IRAR (P=0.029), systolic blood<br />pressure (P=0.022), diastolic blood pressure (P=0.038), and serum triglyceride (P=0.019) were reduced, while<br />serum Resistin, AR, total cholesterol, high density lipoprotein, and low density lipoprotein did not change<br />significantly (P>0.05).Conclusion:Decreases of HOMA-AD and IRAR indices, systolic blood pressure,<br />diastolic blood pressure, and serum triglyceride after twelve weeks endurance training in inactive lean men<br />indicate that endurance training can be useful for metabolic and cardiovascular health of inactive lean men via<br />improving insulin resistance, blood pressure, and circulating levels of triglyceride.<br /><br /> <br /><br />Aim: Inactivity can adversely affect on health of lean subjects.
