Percebam, no início da animação, como há uma assíntota que se aproxima de um limite. Mark Denny, professor de biologia da universidade de Stanford, determinou, no caso dos 100 m, um limite matemático igual a 9.48 s. Achei interessante a afirmação em negrito, abaixo:
An excellent example of the potential for a continued increase in men’s speeds is provided by the recent world records set in the 100m and 200m races by Usain Bolt of Jamaica. Over a span of 3days in the Olympic games of 2008, Bolt ‘shattered’ the then existing records, lowering the record in the 100m from 9.72 to 9.69s and in the 200m from 19.32 to 19.30s. Because Bolt is exceptionally tall for a sprinter (65, 1.96m), he was hailed by the press as a physical ‘freak’ and the harbinger of a new era of sprinting.
Should Bolt’s records cast doubt on the predictions made here? The answer is no. Bolt’s records are only small improvements on the existing records for the 100m and 200m races, 0.3% and 0.1%, respectively, and Bolt’s records are not out of line with the logistic fit to the historical data (Figs7 and 8, pink dots). Furthermore, there have previously been similar jumps in record speed. Thus, as admirable as they are, there is nothing in Bolt’s records to suggest that the predictions made here are inaccurate or that human speeds in the 100m and 200m races are limitless.
