Abstract

      Background and Objectives: Diabetes induced oxidative stress plays an important role in pathological damage to the heart and liver by increased production of extracellular matrix. It is thought that the use of medicinal plants, particularly Portulaca oleracea. L and regular exercise are effective. The aim of this study was to evaluate the effects of Portulaca oleracea. L consumption along with resistance training on cathepsin S, cystatin C and C-reactive protein (CRP) levels on type 2 diabetes patients.

     Methods: In this semi-experimental study, 28 female type 2 diabetes patients with a mean age of 52 were randomly devided into 4 groups of control, exercise, supplement and supplement-exercise. Portulaca oleracea. L supplement was cosumed 7.5 g per day. Resistance training program was performed with a rubber band for 8 weeks, 3 days a week for 60 minutes with40-50% intensity, up to a maximum repetition. Blood samples were taken before and 48 hours after the last intervention.

     Results: After eight weeks, cathepsin S, cystatin C and CRP levels in the supplementation and supplementaion-exercise group were significantly reduced (P<0.05). There were also significant differences between the groups.

    Conclusion: Portulaca oleracea. L consumption and resistance training have each separate positive impacts on the cathepsin S, cystatin C and CRP levels, but the simultanous effect of Portulaca oleracea. L seed consumption and physical activity can lead to a better efficiency.

ABSTRACT

       Background and Objective: Osteoporosis is one of the complications of diabetes. The aim of this study was to determine the impact of resistance training along with Portulaca oleracea supplementation on OPG and NFκB levels (bone markers) in women with type II diabetes.

       Methods: Overall, 28 women with type II diabetes (44 to 60 years old) were randomly and equally assigned into four groups (supplement, training, training-supplement and control). An eight-week resistance training program (three one-hour sessions per week with one repetition maximum) was performed using three types of bands with different resistances, at 40-50% intensity and 50-70% maximum heart rate. P. oleracea seeds were supplemented daily (7.5 grams mixed in yogurt) for eight weeks. The data was analyzed using descriptive statistics, paired t-test and ANOVA.

       Results: After 8 weeks, OPG and NFκB levels in the three groups of supplement, training and training-supplement increased and decreased, respectively. The highest change in both variables was observed in the training-supplement group. Moreover, the level of these two variables in the training-supplement group had significant difference with the controls and other groups (P=0.000).

       Conclusion: As a non-pharmacological therapeutic approach, the regular resistance training and P. oleracea supplementation can increase bone formation markers and reduce bone resorption in women with type II diabetes.
