Listen up runners and triathletes. ?A new study from Norway shows that supplements might have negative effects on endurance training.
Vitamins have shown to inhibit muscle’s natural reaction to build and repair. Scientists now realize that the existence of excess vitamins, such as vitamins C and E, can inhibit cell’s capability to produce mitochondria, the “powerhouses” which build our cells.
To prove this, they studied two groups of quickly an 11-week period. One group was the controlled placebo group and the other was given real vitamins C and E. The supplement group ingested 1,000 milligrams of vitamin C and 235 milligrams of e vitamin per day. Both groups followed the same regimen of endurance training, which contained running three or four times per week.
The group that showed more mitochondria growth and cell repair was the placebo group. Researchers said this result was expected, as it is an all natural response to endurance training. However, those taking supplemental vitamins had low mitochondria numbers.
Scientists could track producing mitochondria within the cells. They figured the vitamins were preventing the muscle’s natural reaction to increase mitochondria production.
The great news was that the supplements did not hurt the subjects. They were able to train at the same pace as people who didn’t take vitamins. However, the supplement group did not see improvements in cell repair. The 4 people with the very best rise in performance belonged towards the group who weren’t ingesting supplements.
What does this mean for you? Experts say to always ask your physician before beginning any type of vitamin regimen. Supplements could be dangerous if taken in large doses and it is best to check with a specialist before taking them.
The researchers intend to continue their study the effects of vitamins on endurance training to further understand them better.
