30 Seconds Summary
Research Spotlight: Resistance training boosts your antioxidant system more than vitamin D supplementation

  • Vitamin D regulates the body's endogenous antioxidant system, which is crucial for scavenging free radicals.
  • Exercise, particularly resistance training, also significantly influences and boosts the endogenous antioxidant system by increasing production in response to exercise-induced inflammation.
  • A study compared the effects of vitamin D3 supplementation and resistance training on antioxidant capacity and oxidative stress in 40 young men with low vitamin D levels over eight weeks.
  • Participants were divided into four groups: resistance training with vitamin D3 supplementation, resistance training with a placebo, vitamin D3 supplementation only, and a control group with placebo and no training.
  • Improvements in oxidative stress markers and antioxidant levels were more significant in the resistance training groups than in the vitamin D3 only group.
  • The study suggests that resistance training enhances the endogenous antioxidant system more effectively than vitamin D3 supplementation alone, even with low initial vitamin D levels.
