Abstract

The influence of paddling cadence on the time to exhaustion (t.lim) and VO2 kinetics at the intensity associated with VO2max (IVO2max) was examined in seven highly-trained white water kayakers. All subjects were engaged in national or international competitions. Subjects took part in three constant-load tests at IVO2max, each test performed at a different paddling cadence (50, 60 or 70 cycles min(-1). The VO2 kinetics recorded during these constant-load tests at IVO2max were fitted with a mono-exponential equation. A significant increase in t.lim (P <.05) was observed as the paddling cadence increased from 50 to 70 cycles min(-1). No effect was found either on values of VO2peak, post-exercise blood lactate concentration, or on the time at which VO2peak was attained (TAVO2peak). Our results suggest that experienced kayakers may choose a high paddling cadence during physiological assessments at IVO2max. Further experiments are needed in order to identify the physiological significance of t.lim at IVO2max.
