Purpose: The purpose of this study was to examine the effect of 12 week a selected aerobic exercise program on body composition, lipid profile, and working ability of employees involved overweight and obese. Method: In this semi-experimental study with pre-test, post-test design and control group, 65 overweight employees were selected by purposive sampling method and randomly assigned to exercise and control groups. Then aerobic exercise program three sessions per week and each session 65-50 minutes, was performed for 12 weeks for the experimental group. The control group did not have such an intervention. Body composition indices, workability index and, lipid profile were measured before and after the training protocol for both groups. Data were analyzed using the covariance test (ANCOVA). Results: The results showed that aerobic exercise significantly reduced body composition indices, including (fat percentage, body mass index, and waist to pelvic ratio) and total cholesterol, triglyceride, low-density lipoprotein (LDL) the exercise group compared with the control group. The levels of high-density lipoprotein (HDL) and the ability to work index of the exercise group also increased (P <0.05). Conclusions: The results indicated that aerobic exercise could improve body composition, lipid profile and workability index, and prevented contracting chronic diseases, reducing their ability to work, and retiring early in overweight and obese employees.

Purpose: The aim of this study was to compare the effects of three methods of endurance, resistance and concurrent training on aerobic fitness and body composition male students with overweight. Methods: Forty five overweight male who were resident of Shahed university dormitory were purposefully selected and randomly assigned into following groups: endurance, resistance and concurrent training. Each Group performed their own protocol for 8 weeks, 3 times per week with specified intensity and duration. Before starting the protocol and 24 hours after the last training session, body composition parameters and aerobic fitness were measured at same condition. Data were analyzed using analysis of covariance. Results: The findings showed that three methods of endurance, resistance and concurrent training protocol had a significant effects on aerobic fitness and body composition parameters. In comparing the difference between groups of three methods of endurance, resistance and concurrent training on aerobic fitness and body composition parameters were significantly different and the variables of aerobic fitness and body composition parameters of concurrent training was more effective than two other exercises. Innovation this research is identical the work out of training (time) in the 3 protocol that to compare intergroup among the most effective way to same time identification. Conclusion: It seems that eight weeks of endurance, strength and concurrent exercise training have effects on aerobic fitness and body composition parameters male students with overweight but all three types of exercise separately with diet modification could be improved aerobic fitness and body composition indices.
