The inclusion of the term aerobic inertia into the model of critical velocity applied to canoeing

Abstract

The aim of this study was to test the effects of addition of the “inertia” aerobic term [Time = AWC_inertia / (Velocity – CV_inertia . (1 - exp ^{(-tempo/Ï„)}))] in the traditional hyperbolic velocity-time equation in canoeing. The distances ranging 130-2.000 m were covered by male (M) and female (F) canoeists in maximal velocity. In both groups, CV_inertia (M: 3,19 ± 0,17 m/s; F: 2,94 ± 0,11 m/s) was significantly lower than CV (M: 3,31 ± 0,21 m/s; F: 3,01 ± 0,14 m/s), and the opposite pattern was observed between AWC_inertia (M: 165,5 ± 33,0 m; F: 139,0 ± 30,3 m) and AWC (M: 103,6 ± 32,6; F: 105,3 ± 20,7 m). The aerobic participation predicted by the proposed “inertia” model during several distances, provided estimates close to those defined by the literature. Therefore, it was concluded that the inclusion of the “inertia” term can provide adequate estimates of aerobic contribution during canoeing.
