This leads to a search for suitable and accessible forms of PA with sufficient effects on BMD. CrossFit (CF) could be among these forms of PA. Exercises included in a CrossFit (CF) training program should contain stimuli that lead to bone mass remodeling and, therefore, could positively influence the development and maintenance of bone mineral density (BMD). However, the results verifying the effect of CF on BMD are inconsistent in the current studies. The aim of the study is to investigate the impact of CrossFit training with an average weekly volume of 511.3±124.4 and 202.5±34.2 minutes in middle-aged individuals on their BMD.
