The effect of eight weeks of resistance training with vitamin D supplementation on interleukin-6 and interleukin-15 overweight women

The current study was to examine the effect of eight weeks resistance training with D vitamin consumption on Interleukin 10 & 15 in overweight women.

In semi experimental study with pre-post phases, 60 over weight women with age range 20-35 years old selected and those located in 4 groups: resistance training, D vitamin consumption, resistance training with D vitamin consumption and placebo. Blood sampling collected in pre test phase and post test phase (after 8 weeks training). The training protocol consisted of 8 weeks of resistance training, which was held three sessions per week. Participants in two groups of daily vitamin intake consumed 1 unit of vitamin D in capsules (at night and before going to bed). Participants in the placebo group also received a placebo from lactose. Data were analyzed by analysis of variance with repeated measures.

The results showed that resistance training and resistance training along with vitamin D significantly reduced interleukin-6 and significantly increased interleukin-15 in overweight women. Other results showed a greater effect of resistance training with vitamin D compared to resistance training alone in reducing interleukin-6 and increasing interleukin-15.

Overall, the current results suggest that overweight and obese women using vitamin D combined with resistance training may be able to prevent the inflammatory stress caused by moderate exercise and its aftermath.
