dc.description.abstract | The purpose of this investigation was to compare and determine the relevance of the morphological
characteristics and variability of running speed parameters (stride length and stride frequency) between Usain Bolt’s
three best 100 m performances. Based on this, an attempt was made to define which factors determine the performance
of Usain Bolt's sprint and, therefore, distinguish him from other sprinters. We analyzed the previous world record of
9.69 s set in the 2008 Beijing Olympics, the current record of 9.58 s set in the 2009 Berlin World Championships in
Athletics and the O lympic record of 9.63 s set in 2012 London Olympics Games by Usain Bolt. The application of
VirtualDub Programme allowed the acquisition of basic kinematical variables such as step length and step frequency
parameters of 100 m sprint from video footage provided by NBC TV station, BBC TV station. This data was compared
with other data available on the web and data published by the Scientific Research Project Office responsible on behalf of
IAAF and the German Athletics Association (DVL). The main hypothesis was that the step length is the main factor
that determines running speed in the 10 and 20 m sections of the entire 100 m distance. Bolt’s anthropometric
advantage (body height, leg length and liner body) is not questionable and it is one of the factors that makes him faster
than the rest of the finalists from each three competitions. Additionally, Bolt’s 20 cm longer stride shows benefit in the
latter part of the race. Despite these factors, he is probably able to strike the ground more forcefully than rest of
sprinters, relative to their body mass, therefore, he might maximize his time on the ground and to exert the same force
over this period of time. This ability, combined with longer stride allows him to create very high running speed - over
12 m/s (12.05 -12.34 m/s) in some 10 m sections of his three 100 m performances. These assumption confirmed the
application of Ballerieich's formula for speed development. In most 10 m sections of the 100 m sprint, the step length
was the parameter that significantly determined the increase of maximal running speed, therefore, distinguishing Bolt
from the other finalists. | |
