Obese

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.

Background: Increasing prevalence rate of anxiety disorders in elderly populations especially due to physical limitations has become a key concern for health authorities. Aim : The objective of the study was to investigate the effects of cognitive and physical training on physiological and psychological Levels of anxiety in the elderly. Material and Methods: Forty-nine aged females (62.3±2.6 years) with BMI of 35-49.99 kg/m<sup>2 were assigned to one of three groups: Cognitive (n= 17), Physical training [yoga] (n= 16) and control group (n= 10). The cognitive training protocol included breathing and imagery/visualization techniques, which lasted for an 8-week period, three sessions a week. Yoga practices comprising Asana and Pranaya training, three times a week, for two months. The State-Trait Anxiety Inventory was given before and after intervention training. Biofeedback devices was used to monitor galvanic skin resistance and resting heart rate (as physiological and psychological markers of anxiety) in pretest and pre-test phases. The data were analyzed using analysis covariance and Bonferroni post hoc test. Results: It was indicated that anxiety score in cognitive training was significantly lower than control group ( P = 0.002) and also, anxiety score in physical Training was significantly lower than control group ( P = 0.01). No significant difference was found between the two training groups ( P = 0.18). Furthermore, both training groups had lower galvanic skin resistance ( P < 0.001). In addition, physical training group had a better status of resting heart rate after intervention compared to the cognitive and control groups (respectively, P = 0.04 and P = 0.001). Conclusions: It was concluded that the health benefits of Physical training [yoga] isn’t not specific to maintaining physical health, but also extends to lowering the anxiety in elderly with obesity. It was also suggested that cognitive training can mitigate the anxiety symptoms in the elderly while no physical changes were shown in cognitive training.

Purpose: Obesity is a complex disease that causes oxidative stress by disrupting fat metabolism. The aim of this study was to investigate the effect of ten weeks of swimming exercises with nigella sativa (Black Seed) supplementation on the plasma lipid profile of inactive obese women. Method: In this study, 40 inactive obese women with a body mass index (BMI) higher than 26, and an average age (29.06 ± 7.94 years), were voluntarily selected and randomly divided into four groups of 10 people. The control group, the training group, the training group - nigella sativa supplement and the nigella sativa group were divided. The control group had a normal diet and no training; the nigella sativa supplement group consumed 2 nigella sativa capsules of 1000 mg daily for 10 weeks; The swimming training group performed swimming exercises for 10 weeks and three sessions a week with an intensity of 60% of the maximum heart rate and the duration of each session was 75 minutes; the nigella sativa -training group also performed both the training and supplement protocols. At the end of the period, blood indicators of (low-density lipoprotein (LDL), high-density lipoprotein (HDL), triglyceride (TG) and total cholesterol. Total (TC)) and anthropometric variables were measured. Covariance analysis and paired t-test at a significance level of 0.05 were used for data analysis. Results: Investigations showed that there is no significant difference between the groups in the values of HDL-C, LDL-C, TG and TC (P>0.05). However, in the intra-group comparison, hockey results have a significant difference in HDL-C, LDL-C, TG and TC in the exercise and exercise +supplement and nigella sativa groups (P>0.05). Conclusion: It seems that taking two weeks of swimming exercises along with nigella sativa supplement improves some of the fat profile indicators and can probably be effective in improving the complications caused by obesity.
