Vitamins C and E Can Inhibit Physical Performance

Los Angeles, CA -- (SBWire) -- 02/11/2014 --Nutritional supplements are meant to do as their name implies – supplement missing pieces of a person’s nutritional intake to enhance health or physical performance. But one must exercise caution when choosing supplements as a recent study from the Norwegian School of Sports Sciences has found that some supplements can actually impede physical development rather than promote it.

A study consisting of 54 healthy participants who were randomly assigned to take vitamin C and E supplements or a placebo showed that those on the placebo had better results in muscle growth from training than those who were taking the supplements. It was suggested that vitamins C and E actually blunt the endurance training-induced increase in hormones and proteins that are responsible for muscle development.

The supplements did not alter or hurt the participants current performance levels, and both groups showed improvements in their levels of oxygen intake, which indicates improved cardiovascular endurance. However, despite this the group taking the supplements did not experience an increase in muscle development, which overtime could impede or inhibit performance enhancement in those training for endurance.

Determining exactly how supplements can interfere with muscular endurance will require further research, but the findings of the study can provide a guideline for those currently looking to enhance their physical performance. Vitamin C and E supplements can help increase health and prevent illnesses during winter months, but should be used with caution by those looking to enhance physical performance in a sport or just in their personal lives.
