In long distance events (eg triathlon, marathon, race walking…) the maximal speed that
athletes can sustain depends on the capacity of the subject to support the highest fraction of
VO2max and to spend the lowest amount of metabolic energy during the whole race [14]. In
this case the energy cost of locomotion, defined as the amount of energy spent per unit
distance, contributes significantly to long duration performance [4, 7, 13, 32, 37]. It is well-
known that the energy cost of locomotion also reflects the biomechanical demand …

The purpose of this study was to examine the relationship between cadence and oxygen
consumption with exercise dura-tian. Ten triathletes who trained regularly were examined.
The first test was always a maximal test to determine maximal oxy~ gen uptake (VOzmax).
The other sessions were composed of six submaximal tests representing 80% of the
maximal power reached with VOzmax (Pmax). During these tests submaximal rides with a
duration of 30 min were performed. Each test represented, in a randomised arder, one of the …
