Effects of 12 Weeks of Whole-Body Vibration Training and Vitamin D Supplementation on Bone Density and Muscle Quality in the Aged with Osteosarcopenia: A Randomized Controlled Trial.

What Was Tested

This randomized controlled trial looks at Vitamin D, K2, Magnesium and Zinc.

Osteosarcopenia (OS) is a common geriatric condition, which seriously impairs the quality of life of the elderly, but there is a lack of research on its mechanism and treatment.

Who Took Part

PubMed indexes the participants as middle-aged adults and older adults, both men and women.

Subjects meeting the enrollment criteria were recruited from the Affiliated Hospital of Shaanxi University of Traditional Chinese Medicine.

Forty-eight volunteers were enrolled and divided into a control group and a WBVT group, with 24 in each.

How the Study Was Run

The researchers set it up as a randomized study.

Random assignment meant chance, not the researchers, decided who got Vitamin D, K2, Magnesium and Zinc and who got the comparison, which limits bias.

Primary outcomes were lumbar, hip, and forearm bone mineral density (BMD), appendicular skeletal muscle mass measured by dual energy X-ray absorptiometry, and handgrip strength.

Secondary outcomes included serum MSTN, irisin, bone turnover markers, physical performance (assessed by 5-time chair stand test, 6-m walk, and SPPB), and adverse events in the trial.

What Was Measured

The subject headings attached to it are Bone Density, Vibration, Sarcopenia, Myostatin, Vitamin D, Fibronectins and Dietary Supplements.

The authors tagged it with the keywords Osteoporosis, Osteosarcopenia and Whole-body vibration training.

What This Means in Plain Language

The paper is a randomized study of Vitamin D, K2, Magnesium and Zinc.

Results are reported in around 6 sentences of the abstract; we leave them to the paper itself rather than summarise them.
