What This Study Did, in Plain Language
What Was Tested
Researchers studied Vitamin D, K2, Magnesium and Zinc in this randomized controlled trial publication.
Pre- and post-measurements included 1) serum 25-hydroxy vitamin D (25(OH)D); 2) body composition variables (total body lean, fat, and bone mass) using dual-energy X-ray absorptiometry (DXA) scans and 3) vertical jump test to assess peak power output.
Who Took Part
PubMed tags the participants as both men and women.
Members of a men's and women's NCAA D1 Basketball team were recruited.
How the Study Was Run
The researchers set it up as a randomized, double-blind and placebo-controlled study.
The participants were allocated by chance, so the Vitamin D, K2, Magnesium and Zinc group and the comparison group should start out alike.
As a double-blind Vitamin D, K2, Magnesium and Zinc study, the assignments were hidden from both participants and investigators until the end.
Some participants received a placebo instead of Vitamin D, K2, Magnesium and Zinc, giving a reference point.
Dietary intake was assessed using Food Frequency questionnaires.
Main outcome measures included changes (∆: post-intervention minus pre-intervention) in 25(OH)D, body composition, and performance.
What Was Measured
The subject headings attached to it are Basketball, Body Composition, Cholecalciferol, Dietary Supplements, Vitamin D and Vitamins.
Author keywords: 25-hydroxyvitamin D and sweat sodium.
