Participants who took vitamin D cycled further in a test with reduced signs of physical exertion
A new study conducted in the UK revealed, that healthy adults who took vitamin D supplements saw an increase in their cycling performance, as compared to those who were given a placebo.
In previous studies, vitamin D was thought to block the “stress hormone’ cortisol, which was believed to improve athletic performance and also lower cardiovascular risk.
Indeed, the new study confirmed, that participants who received vitamin D showed signs of lower blood pressure, as well as lower levels of cortisol in their urine, as compared to those who were given a placebo. Moreover, the study found that those who were given vitamin D, cycled further in 20 minutes (6.5km vs. 5km), than those who received a placebo. Also, the participants who were given vitamin D showed lower signs of physical exertion, as evidenced by systolic and diastolic blood pressure.
By comparison, the group who were given the placebo, showed no significant improvements in performance, or a reduction in cardiovascular disease risk factors.
Although vitamin D is present in many food groups, and the body produces it naturally via sun exposure, regardless whether or not a person is seeking a boost in performance, the study recommends that people should take vitamin D supplements during the winter months when there’s less exposure to light.
