SOUTHAMPTON, England, April 14 (UPI) -- In studying bone development in growing children, scientists at the University of Southampton found greater muscle mass is linked with healthier bones. Fat, on the other hand, was found to be unrelated to bone development.
Researchers at Southampton's Medical Research Council compared muscle mass and bone density data collected as a part of the Southampton Women's Survey. Measurements from 200 children -- including imaging to determine bone mineral density, shape and size of the tibia, as well as overall skeletal composition -- were recorded shortly after birth. Followup measurements were taken as the participants turned six or seven years old. Scientists found a significant correlation between greater muscle mass and stronger, sturdier bones.
