The purpose of this research was to investigate the effect of four weeks of moderate aerobic training and nanocurcumin supplementation on IGF- 1 gene expression and its receptor in the soleus muscle of rats.

Materials and Methods

32 male Wistar rats, approximately eight weeks old, with a weight range of 200±10 grams, were prepared and kept for one week under standard conditions of light, temperature, and humidity. Rats were randomly divided into 4 groups of 8 series: healthy control group, aerobic training group, nanocurcumin group and aerobic training + nanocurcumin group. The training protocol was for 4 weeks, 5 days a week, in the first week, 20 minutes of activity with a speed of 18 meters per minute, and finally in the 4th week, it reached 35 minutes of activity with a speed of 20 meters per minute. Nanocurcumin supplement was also used for each animal at 80 mg / kilogram of body weight. One-way analysis of variance and Bonferroni's post hoc test was used at the significance level (P<0.05).


The results showed an increase in IGF-1 and IGF-1R gene expression levels in the soleus muscle in all groups compared to the control group.


The combination of training and nanocurcumin supplementation probably increases the antioxidant capacity of the body and causes a greater increase in the expression of the IGF-1 gene and IGF-1R in skeletal muscles, which indicates more anabolic effects.
