Summary

The career of a sprinter is analyzed with U. Bolt achievements as an example. The effects of the increase of body mass and ageing are discussed within the framework of the polynomial models for the velocity, muscular isometric force and age. The analysis presented demonstrates the influence of the BM factor in analyzed racing. The nonlinear increase of the BM for 9 kg in the period 2009 – 2017 in was one of the reasons of Bolt’s unsuccessful attempt to repeat or confirm the time 9.58 s. Another limiting factor was the fact that due to the age, Bolt was not able to increase isometric muscular force which, after the year of maximal efficiency (2009) decreased.

KEY WORDS: Ageing; Increase of body mass; Isometric Force; Polynomial Model; Velocity.
