Decrease in Ionized and Total Magnesium Blood Concentrations in Endurance Athletes Following an Exercise Bout Restores within Hours-Potential Consequences for Monitoring and Supplementation.

What Was Tested

Researchers studied Vitamin D, K2, Magnesium and Zinc in this randomized controlled trial publication.

Magnesium is essential for optimal sport performance, generating an interest to monitor its status in athletes.

However, before measuring magnesium status in blood could become routine, more insight into its diurnal fluctuations and effects of exercise itself is necessary.

Who Took Part

By PubMed's age tags, the people studied were young adults and adults, both men and women.

How the Study Was Run

The researchers set it up as a randomized and crossover study.

Because people in this Vitamin D, K2, Magnesium and Zinc study were split into groups at random, differences between the groups are less likely to reflect who happened to join each one.

In the crossover set-up each of the participants took both Vitamin D, K2, Magnesium and Zinc and the comparison in turn, acting as their own control.

The control day was included to correct for a putative diurnal fluctuation of magnesium.

What Was Measured

However, before measuring magnesium status in blood could become routine, more insight into its diurnal fluctuations and effects of exercise itself is necessary.
