Therefore, the aim of the present study was to investigate the effect of functional training on brain-derived neurotrophic factor and executive functions in obese elderly men.</span></span><span style="font-size:12.0pt"><span style="font-family:"Times New Roman","serif""></span></span></span></span></span></span></span><br> <span style="font-size:11pt"><span style="line-height:normal"><span style="tab-stops:45.8pt 91.6pt 137.4pt 183.2pt 229.0pt 274.8pt 320.6pt 366.4pt 412.2pt 458.0pt 503.8pt 549.6pt 595.4pt 641.2pt 687.0pt 732.8pt"><span style="unicode-bidi:embed"><span calibri="" style="font-family:"><b><span lang="EN" style="font-size:12.0pt"><span new="" roman="" style="font-family:" times="">Methods</span></span></b><span lang="EN" style="font-size:12.0pt"><span new="" roman="" style="font-family:" times="">: The present study was a quasi-experimental study with a pre-test-post-test design.
