Abstract
The aim of this study was: i) to compute an energy balance of a
slalom kayak competition by measuring the percentage contributions
of the aerobic and anaerobic energy sources to total metabolic
power (E˙ tot); and ii) to compare these data with those obtained,
on the same subjects, over a flat-water course covered at
maximal speed in a comparable time. Experiments were performed
on eight middle- to high-class slalom kayakers (24.8 ±
8.1 years of age,1.75 ± 0.04mof stature, and 69.8 ± 4.7 kg of body
mass) who completed the slalom race in 85.8 ± 5.3 s and covered
the flat water course in 88.1 ± 7.7 s. E˙ tot was calculated from
measures of oxygen consumption and of blood lactate concentration:
it was about 30% larger during the flat water all-out test
(1.72 ± 0.18 kW) than during the slalom race (1.35 ± 0.12 kW).
However, in both cases, about 50% of E˙ tot derives from aerobic
and about 50% from anaerobic energy sources. These data suggest
that, besides training for skill acquisition and for improving
anaerobic power, some high intensity, cardiovascular conditioning
should be inserted in the training programs of the athletes
specialised in this sport.
