Purpose: The world is getting old. Alzheimer's disease is a progressive disease, which in case of no intervention, this ratio reaches 4 more advanced stages in people over 85 years old. Some methods have shown that they can be effective in preventing and slowing down the course of the disease. The purpose of this study was to investigate the role of aerobic exercise program on the quality and Lipid profile related to sleep in the elderly with Alzheimer's disease. Method: 22 elderly people with Alzheimer's disease were randomly divided into two groups of 11 people: aerobic exercise and control. The subjects in the aerobic training group practiced three sessions every week for twelve weeks and each session lasted for 45 minutes. The sleep quality of the subjects was evaluated by the Pittsburgh Sleep Quality Questionnaire (PSQI). Lipid profile related to sleep (TG, TC, LDL, HDL) was also measured by blood sampling before and after twelve weeks of aerobic training. Results: The results showed that the sleep quality of the subjects improved by 31% in the Pied Heroi group, which was statistically significant. In addition, there was a significant improvement in the changes of TG (p=0.034), TC (p=0.017), LDL (p=0.006), and HDL (p=0.016) in the aerobic training group. The results of the independent t test also showed that there was a significant difference in sleep quality between the aerobic exercise and control groups. However, no relationship was observed between changes in sleep quality and changes in Lipid variables related to sleep. Conclusion: It can be concluded that twelve weeks of aerobic exercise improves sleep quality along with Lipid profile related to sleep in the elderly with Alzheimer's disease and will be useful as a way to treat sleep problems in the elderly.

Purpose: The aim of this study was compares the effects of 10 weeks High Intensity Interval training (HIIT) and moderate intensity aerobic training (MIAT) on serum levels of homocysteine and some cardiovascular risk factors in overweight inactive men. Methods: In this semi-experimental study, nineteen overweight men voluntarily participated in this study and were randomly divided to 2 Groups: High Intensity Interval training (HIIT) and moderate intensity aerobic training (MIAT). Subjects performed training programs for 10 weeks, 3 sessions per week. The levels of homocysteine and lipid profile were measured before and after 10 weeks of training programs. For statistical data analysis, independent and paired t tests were used and considered significant at a p≤0.05. Results: The results of this study showed that both High Intensity Interval training and moderate intensity aerobic training caused a significant reduction of homocysteine levels (P≤0.05). After 10 weeks of high -intensity periodic exercise, cholesterol levels (p = 0.001), LDL (p = 0.002) decreased significantly and HDL levels were significantly increased (p = 0.001), In MIAT training group, only a significant reduction in cholesterol was found (P=0.006). Conclusion: According to the results of this study, it seems that both High Intensity Interval training and moderate intensity aerobic training have favorable effects in reducing body weight and some cardiovascular risk factors.

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.
