The Effect of resistance training circuit with Medicago sativa extracts on levels of Osteoprotegerin and Nuclear Factor of Kappa-B in thin girls

Osteoporosis is the most common metabolic bone disease with high prevalence that various factors are involved in the pathogenesis of this disease, including the low body mass index and lack of physical activity. Change in lifestyle represents a successful strategy to prevent future disease. Therefore the aim of this study was determine the interactive effects of resistance training and Medicago sativa extracts consumption on serum level of steoprotegerin and nuclear factor kappa B in thin girls.
In one Quasi-experimental study, 28 female students (16 to 19 years) divided into 4 groups, including: supplement, training , training-supplement and Control randomly. Resistance training program consisted of 10 exercise movements at 60-80% of one repeated maximal in 8-12 repetition (in 3 circuits), 60 min per day and 3 sessions per week for 4 weeks. Intake Medicago sativa supplement was 1 ml/kg body weight for 3 times a day. Data were analyzed with Paired t and ANOVA tests ( PFour weeks of resistance training, supplementation and the combined intervention were associated with a significant increase in steoprotegerin and decrease in nuclear factor kappa B levels (P Regular resistance training with consumption of Medicago sativa extracts as a non-drug therapy can increase bone formation markers and also reduce the activity of the absorbency pathway in thin adolescent girls. Of course the combination of exercise and supplement are more effective than the separate effects of each them.
