Abstract

Background and Objective: Working in sitting posture, specially using a poorly designed chair is one of the critical risk factors in developing low back pain. Low back pain is one of the most common musculoskeletal disorders (MSDs) and has been reported to occur in 50-90% of all adults with recurrent rate of up to 90%. The objective of this study was to design and develop ergonomic chair for Iranian office workers. Materials and Methods: In this study, chair-related anthropometric dimensions of 303 Iranian office workers were measured in both genders. ANSI-HFES 100/1988 standard protocol was used for chair design. Finally, using a usability test, the designed ergonomic chair was assessed by 60 men and women office workers. Results: Using anthropometrics measurements and ergonomic criteria for chair design and also considering technical limitations, an ergonomic chair was made. Then this ergonomic chair was compared with old made chair designs. Office workers' assessments between old chair design and new one showed a significant difference. Conclusion: In this study, design and development of construction of an ergonomic chair was successfully made which could be applicable to Iranian office workers in order to provide their comfort and well being.

Abstract

Background and Objective: Adiponectin plays an important role in hyperglycemia, lipolysis, and inflammatory mechanisms. However, mechanisms responsible for the relationship between adiponectin and insulin resistance in response to exercise, still remains unclear. The aim of this study was to determine the effects of a six-week-long high intensity interval training (HIIT) on plasma adiponectin levels, insulin sensitivity, insulin resistance, and β-cells function in sedentary young men. Materials and Methods: Eighteen students voluntarily participated in the study and were randomly divided into two groups: Experimental (n=9, age=24.33 ±1.41 yr, height=176.22 ±4.91 cm, weight=72.27 ±6.59 kg) and Control (n=9, age=23.27 ±2.01 yr, height=180.22 ±6.88 cm, weight=76.27 ±7.33 kg) groups. The test group performed three HIIT sessions per week for 6 weeks. Each session consisted of four to six repeats of maximal sprint running within a 20-m area with 30 s recoveries. Fasting blood samples were collected immediately before and after the exercise protocol. Data were analyzed by dependent and paired t-tests. Results: The results indicates that while plasma adiponectin levels in the experimental group increased significantly (P= 0.047), there was a significant decrease in the percentage of body fat (P= 0.019). There were also a decrease in serum concentrations of insulin, fasting glucose and insulin resistance values as well as an increase amounts of insulin sensitivity and beta cells function. However, these changes were not statistically significant (P>0.05). Conclusion: Our findings show HIIT is a time efficient method for increasing adiponectin levels and reducing body fat. Also, the intensity of exercise as an important factor in the increase in adiponectin levels could be noted.

Abstract

Backgrounds and Objective: The main important factors in decreasing cognitive performance are aging, proinflammatory and metabolic syndrome. The aim of this research was investigation the effect of twelve week aerobic exercise whit moderate intensity on IL-6, IL-10, and cognitive performance in 50-65 years old women with syndrome metabolic.

Materials and Methods: 24 women with metabolic syndrome (MetS) voluntarily took part in the study and were divided into two groups: MetS exercise (ME), MetS control (MC). The ME group participated in an aerobic exercise training (AT) program (12 weeks), three sessions per week, each session containing three performance parts and two rest parts. Also blood samples were drawn before and after training to evaluate levels of IL-6, IL-10. Cognitive performance was measured by digit span memory test. Data were analyzed using Pearson coefficient, pried-sample T-Test, and independent samples T-Test.

Results: After three months of aerobic exercise, IL-6 levels decrease while IL-10 levels and cognitive performance increased significantly (P<0.05). IL-6, IL-10, and cognitive performance in the control group were not altered after three months (P<0.05).

Conclusion: These findings indicate that three months of aerobic exercise can increase IL-10 level and decrease IL-6 while ameliorating cognitive performance.
