Effect of 8 weeks resistance training along with omega-3 fatty acid supplementation on resting levels of some pro-inflammatory cytokine of older women
Abstract
Aim: Cytokines are a group of proteins that play a central role in mediating inflammatory responses topathological stimuli such as infection and tissue damage.The goal of present research was to investigationthe effect of resistance training along with omega-3 fatty acid supplementation on resting levels of somepro-inflammatory cytokine (TNF-α, IL-6) of older women. Methods: Subjects were whom 24 elderlywomen (average age: 79.6 ± 4.2 years, height 151.7± 4.2 cm, weight 60.8±8.7kg, BMI 26.4±3.3kg/m²).Subjects were chosen purposefully and randomly divided in to 3 groups of the first empirical group (n=8),resistance training along with omega-3 fatty acid, the second empirical group (n=8) just resistancetraining, and the third one (n=8) as a control group. The subjects participated in resistance training for 8weeks, 3 sessions every week by 60-80% intensity with maximum repitation incloding foot press, chestpress, shoulder press, the front arm, triceps, sheet pool, hip flextion, hip extention, hip abduction .Theferst empirical group recived 3gr of omega-3 fatty acid at a day within 8 weeks. Pro-inflammatorycytokine was measured using blood sample and ELISA method after 8 hours of an empty stomach in theamount of 3 c.c from interior vein of subjects arms befor and after 8 weeks of exercise. Results: Resultsshow Interleukin-6 and TNF-α have significant decrees after the test into empirical groups while there isno significant in control group. Also, there is graet difference of IL-6 and TNF-α among 3 groups. Posthoctest showed a mean difference in training and supplementation group is greater than training alonggroup. Conclusion: It seems resistance training along with omega-3 fatty acid supplementation. Can havegreater effect than training along on pro-inflammatory cytokine of older women decrees.
