Despite what one might expect about the role of age in such a high-performance athlete as Usain<br \/>\nBolt, our results show that his performance has been essentially constant from Beijing 2009 to Rio<br \/>\n2016, with the mass gain and tailwind conditions making the difference in the run times he has<br \/>\nachieved since Berlin 2009.
