Beneficial effects of exercise, testosterone, vitamin D, calcium and protein in older men-A randomized clinical trial.

What Was Tested

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

The main outcome measure was the 30-s chair stand test, due to test performance correlating with the risk of serious fall injuries and lower extremity muscle strength.

Who Took Part

According to the abstract, 148 men were involved.

PubMed indexes the participants as older adults and people over 80, men only.

How the Study Was Run

The researchers set it up as a randomized, double-blind 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.

As a double-blind Vitamin D, K2, Magnesium and Zinc study, the assignments were hidden from both participants and investigators until the end.

A placebo (an inactive look-alike) gave the Vitamin D, K2, Magnesium and Zinc group a baseline to be compared against.

What Was Measured

The subject headings attached to it are Calcium, Dietary Proteins, Dietary Supplements, Exercise, Muscle Strength, Resistance Training and Testosterone.

Author keywords: elderly, falls, physical exercise and testosterone therapy.
