Is gymnastics exposure associated with skeletal benefits at the forearm in young children?
Routledge
This first author chapter proceeding from 'Children and Exercise XXVIII The Proceedings of the 28th Pediatric Work Physiology Meeting' aimed to investigate whether gymnastic exposure was associated with estimated bone strength development derived from pQCT at the distal radius in young males and female. I was the recipient of the Hans Stoboy and Best Oral Presentation for the presentation of this research at the 2013 PWP Biannual Meeting.
