Different works performed on other populations (elderly people, diabetics) illustrated increased SHBG concentrations with physical training (Hayes et al., 2015; Kim et al., 2017), while Maynar et al. (2010) showed an increase in SHBG in young male weightlifters after 20 weeks of strength training without any change in T, resulting in a decrease in FAI. This evidence concerns the gene SHBG and diabetes mellitus.
