Objectives: Advancements in health care systems and technologies have lowered the rate of mortality leading to an accelerated increase of aged population in Iran and worldwide. Therefore, the aim of the study was to investigate the effect of aerobic exercises on quality of life in healthy aged sedentary men. Methods: In this randomized controlled trial, 26 healthy aged men living in Qazvin nursing home participated voluntarily and were randomly assigned in two experimental (n = 13) and control (n = 13) groups. The experimental group performed aerobic exercise protocol three sessions a week for two months. The quality of life was assessed Using SF-36 health survey before and after exercise intervention. The data were analyzed by paired and independent t-tests. Results:The results suggested that quality of life was improved significantly after exercise program (P = 0.001), while no significant change was found in the quality of life in the control group (P = 0.34). Conclusions: Taken together, 8 Week of aerobic exercise program significantly improves the quality of life among the aged persons Additional research with a greater number of subjects and different exercise protocols are required to make crucial decisions regarding the effectiveness of similar exercise programs on aged persons.

Background:Resistin is a recently discovered signal molecule that has been linked to obesity, type II diabetes mellitus (T2DM) and metabolic syndrome. Objectives: This study aimed to assess whether serum resistin is associated with insulin resistance and glucose concentration in males with T2DM. Patients and Methods: Thirty two adult non-trained males with type II diabetes, 34-48 years old and 88-110 kg of body weight, participated in this study by accessible sampling. Fasting blood samples were collected from all participants in order to measure serum resistin, insulin and glucose concentration. Homeostasis Model Assessment of Insulin Resistance (HOMA-IR) was calculated using fasting insulin and glucose. Relations between variables were determined by Pearson correlations. Results: We found that serum resistin had a positive significant correlation with insulin resistance (P = 0.000, r = 0.64). No significant correlation was found between serum resistin and fasting glucose concentration in the studied patients (P = 0.21, r = 0.23). Conclusions: Based on these data, we can argue that circulating glucose concentration is not directly affected by serum resistin in T2DM. It seems that resistin affects glucose indirectly, through insulin resistance.
