What This Study Did, in Plain Language

What Was Tested

The paper reports a study of Vitamin D, K2, Magnesium and Zinc, published as a randomized controlled trial.

A total of 24 young soccer players (age: 17.2 ± 1.16 years, mass: 70.2 ± 5.84, height: 179.1 ± 4.26 cm) were tested at four different time points across one year (T1-September 2019; T2-December 2019; T3-May 2020; T4-August 2020).

After T2 (during COVID-19 lockdown), players were divided into a supplemented (GS) group and a placebo group (GP).

Who Took Part

By PubMed's age tags, the people studied were teenagers.

How the Study Was Run

In design terms this was a randomized and placebo-controlled 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.

The comparison arm used a placebo, so changes seen with Vitamin D, K2, Magnesium and Zinc could be set against what happens without it.

Variables such as 25(OH)D, calcium (Ca), phosphorus (P), parathyroid hormone (PTH), aerobic capacity, speed, and explosive power were measured.

What Was Measured

A total of 24 young soccer players (age: 17.2 ± 1.16 years, mass: 70.2 ± 5.84, height: 179.1 ± 4.26 cm) were tested at four different time points across one year (T1-September 2019; T2-December 2019; T3-May 2020; T4-August 2020).

The subject headings attached to it are Athletic Performance, Bone Resorption, COVID-19, Communicable Disease Control, Dietary Supplements, Physical Functional Performance and Seasons.

Author keywords: blood parameters, home isolation, seasonal variation and training load.

What This Means in Plain Language
