lipid profile

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 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.

Background: Pahlavani wrestling is one of the ancient sports in Iran. However, very few studies have been conducted on various aspects of it.Aim: To investigate the body composition, lipid profile, quality of life, self-concept, and nutritional knowledge of Pahlavani wrestlers of Kermanshah city.Materials and Methods: Fifty-seven adult Pahlavani wrestlers participated in this study. They completed the quality of life, self-concept, and nutritional knowledge questionnaires on three consecutive days, and then, on two separate days, their body composition and lipid profile were also measured.Results: The quality of life, muscle mass percentage, and bone and mineral content were significantly higher than the normal values (P˂0.05). Also, the lipid profile was in a normal state. Conversely, the self-concept, nutritional knowledge, nutritional attitude, and nutritional practice were significantly lower than the normal values of these variables (P˂0.05). Finally, the BMI was significantly lower than the normal value (P˂0.05) and the fat percentage and visceral fat index were not significantly different (P˃0.05) from their normal values.Conclusion: The results indicated that Pahlavani wrestlers of Kermanshah are in favorable conditions in many physical and body composition health indicators, which somehow shows the possible positive effects of this sport on different aspects of health. However, Pahlavani wrestlers had a considerably lower self-concept and nutritional knowledge than the normal values.
