Abstract
Introduction: Metabolic syndrome (MS) is a collection of metabolic disorders and has a close relationship with obesity and oxidative stress (OS). Chia seeds contain fatty-acids and antioxidants that may play a role in improving MS. The present study was conducted to compare eight weeks of combined exercise with and without consumption of chia seeds on OS and lipid profile of women with MS.
Methods: In a quasi-experimental design, 26 premenopausal women aged 40-52 with MS were divided into two groups: one for combined exercise and chia seed consumption (T+S) and the other for combined exercise (T). The T+S group received 20 grams of chia seeds daily (10 grams before lunch and dinner). The eight-week exercise protocol included three sessions of combined training (bodyweight resistance exercise (RPE15-17) and aerobic exercise (60-80%HRR)) per week, lasting 70-90 minutes. Blood samples were collected in a fasting state 48 hours before and after the exercise protocol. The data were analyzed using two-way mixed ANOVA, Mann-Whitney and Wilcoxon tests at a significance level of 0.05.
Results: After eight weeks of intervention, improvements in triglyceride, low-density lipoprotein, and total cholesterol were observed in both groups, and chia seed consumption did not have an additional effect (p<0.05). However, in the T+S group, there was a significant increase in high-density lipoprotein (p=0.03) and total antioxidant capacity (p<0.00) and a decrease in malondialdehyde (p >0.01).
Conclusion: The present study showed that eight weeks of combined exercise with chia seed consumption is more effective in improving oxidative stress and metabolic syndrome.
