The influence of pacing strategy on V̇O2 and supramaximal kayak performance
No full textD. BISHOP, D. BONETTI, and B. DAWSON. The influence of pacing strategy on [latin capital V with dot above]O2 and supramaximal kayak performance. Med. Sci. Sports Exerc., Vol. 34, No. 6, pp. 1041–1047, 2002.
Purpose: The purpose of this study was to investigate the effects of manipulating pacing strategy on [latin capital V with dot above]O2 and kayak ergometer performance in well-trained paddlers.
Methods: Eight well-trained kayak paddlers (500-m time = 115-125 s) first performed a graded exercise test for determination of [latin capital V with dot above]O2max and lactate (La-) parameters. On subsequent days and in a random, counterbalanced order, subjects performed a 2-min, kayak ergometer test using either an all-out start or even pacing strategy.
Results: There was a significantly greater peak power (747.6 ± 152.0 vs 558.3 ± 110.1 W) and average power (348.5 ± 47.6 vs 335.5 ± 44.8 W) using the all-out start strategy, when compared with the even-paced strategy. There was however, no significant difference between the two pacing strategies for peak [latin capital V with dot above]O2, accumulated oxygen deficit (AOD), peak [La-], or posttest pH. Using the all-out start, total [latin capital V with dot above]O2 was significantly greater (7.3 ± 0.8 vs 6.9 ± 0.8 L).
Conclusion: The results of this study indicate that 2-min kayak ergometer performance is significantly greater following an all-out start strategy when compared with an even-paced strategy. The improved performance appears to be attributable to faster [latin capital V with dot above]O2 kinetics, without a significant change in the total AOD (although the AOD distribution was altered)
The effect of three different warm-up intensities on kayak ergometer performance

Purpose: The purpose of this study was to investigate the influence of warm-up (WU) intensity on supramaximal kayak ergometer performance.
Methods: In the initial testing session, eight institute of sport kayak squad members performed a graded exercise test for determination of [latin capital V with dot above]O2max and lactate (La) parameters. In a random, counterbalanced order, subjects subsequently performed WU for 15-min at either their aerobic threshold (W1), their anaerobic threshold (W3), or mid-way between their aerobic threshold and anaerobic threshold (W2). A 5-min passive rest period and then a 2-min, all-out kayak ergometer test followed the WU.
Results: For the three different WU conditions, no significant differences were observed for average power, peak [latin capital V with dot above]O2, total [latin capital V with dot above]O2, total [latin capital V with dot above]CO2, or accumulated oxygen deficit (AOD) during the 2-min test. However, when compared with W3, differences in average power approached significance after both W1 (P = 0.09) and W2 (P = 0.10). Furthermore, when compared with W3, average power during the first half of the 2-min test was significantly greater after W2 (P W2>W3;P < 0.05) and blood [La] (W1<W2<W3;P < 0.05). Despite the significantly different metabolic acidemia after each WU condition, there were no significant differences in the [latin capital V with dot above]O2 responses to the 2-min test. However, the greater metabolic acidemia after W3 was associated with impaired 2-min kayak ergometer performance.
Conclusions: It was concluded, that although a degree of metabolic acidemia may be necessary to speed O2 kinetics, if the WU is too intense, the associated metabolic acidemia may impair supramaximal performance by reducing the anaerobic energy contribution and/or interfering with muscle contractile processes
All-optical pulse-train generation through the temporal analogue of a laser
No full textWe propose a novel scheme for the all-optical generation of pulse trains in optical fibers based on the reflection and refraction of pulses at a time boundary, and the temporal analogue of a laser cavity with gain. Furthermore, this scheme is shown to provide an original and simple way to measure distributed fiber parameters. In particular, we put forth an application of the temporal laser to the distributed sensing of the fiber group-velocity dispersion parameter.Fil: Sparapani, Alexis Cristian.

Equation for modeling two-photon absorption in nonlinear waveguides
No full textWe derive a novel propagation equation for optical waveguides that properly accounts for two-photon absorption (TPA). We start from a simple quantum theory of nonlinear fibers allowing for TPA to be included in a straightforward fashion. The derived equation is shown to be in excellent agreement with numerical results of conventional pump-and-probe schemes and, to the best of our knowledge, is the first single equation capable of correctly modeling-TPA in the context of broadband signals.Fil: Linale, Nicolás Martín.
