Another bodybuilder shown above, Markus Ruhl, has competed at a bulk much greater than Ronnie Coleman’s in spite of being an inch shorter. West Africans tend to have more bone mass than whites, and so you can guess how much more muscular some of the white bodybuilders really are. The evidence regarding testosterone levels is unlcear. The only testosterone-related study representative of the American population did not find a difference in testosterone levels between American white men and African-American men. In this study, if you look at the unadjusted values, it seems that African-American men tend to have slightly higher testosterone levels, but this was not statistically significant, and adjustment for age, BMI, smoking, alcohol consumption and physical activity revealed no statistically significant differences between these two groups. However, more of the testosterone was being converted to DHT (more potent than testosterone; it amplifies the effect of testosterone) in white men, and African-Americans had higher estradiol levels. This study did not report on the distribution of the sensitivity of the androgen receptor to testosterone in the groups, but there have been one or two reports that forms of androgen receptors that are the most sensitive to androgens such as testosterone are somewhat more prevalent among African-Americans (greater sensitivity translates to stronger effect of testosterone on target tissues). So a clear picture awaits more research. https://its.fh-campuswien.ac.at/hackmd/s/JnqeNil1t https://hackmd.iscpif.fr/s/rkrmhM1oxg https://hackmd.diverse-team.fr/s/rydHg-740 https://md.ccc-mannheim.de/s/SJySFt09lx http://tacheles.humanistika.org/s/rJlpebt0eg https://hackmd.astamuse.net/s/SJvV8w5ngl https://hackmd.stuve-bamberg.de/s/x-bffabI0 https://docs.snowdrift.coop/s/6vwMFFiPc https://hedgedoc.catgirl.cloud/s/I34Ez6Gd5 https://hackmd.bangumi.org/s/rkx7HZJehxl https://pad.demokratie-dialog.de/s/oVGf7S7L11 https://hackmd.stuve-bamberg.de/s/hRZ-myP9C https://craigslist-personals.eurolines.nl/ https://craigslist-personals.mijnstartonline.nl/ https://craigslist-personals.rosadoc.be/ https://craigslist-personals.de-vitrine.be/ https://craigslist-personals.velelinkjes.nl/ https://craigslist-personals.maakjestart.nl/ https://craigslist-personals.gratislinken.nl/ https://craigslist-personals.backlinkplaatsen.nl/
