VO2 Kinetics During Heavy and Severe Exercise in Swimming
Abstract The purpose of this study was to describe the VO 2 kinetics above and below respiratory compensation point (RCP) during swimming. After determination of the gas-exchange threshold (GET), RCP and VO 2max , 9 well-trained swimmers (21.0±7.1 year, VO 2max =57.9±5.1 ml.kg − 1 .min − 1 ), comp...

The purpose of this study was to describe the VO

kinetics above and below respiratory compensation point (RCP) during swimming. After determination of the gas-exchange threshold (GET), RCP and VO
2max
, 9 well-trained swimmers (21.0±7.1 year, VO

=57.9±5.1 ml.kg

.min
− 1
), completed a series of “square-wave” swimming transitions to a speed corresponding to 2.5% below (S
− 2.5%
) and 2.5% above (S
+2.5%
) the speed observed at RCP for the determination of pulmonary VO
2
kinetics. The trial below (~2.7%) and above RCP (~2%) was performed at 1.28±0.05 m.s
− 1
(76.5±6.3% VO
2max
) and 1.34 0.05 m.s
− 1
(91.3±4.0% VO
2max
), respectively. The time constant of the primary component was not different between the trials below (17.8±5.9 s) and above RCP (16.5±5.1 s). The amplitude of the VO
2
slow component was similar between the exercise intensities performed around RCP (S

was attained only during trial performed above RCP (S

vs

S
+2.5%
=103.0±8.2% VO

). Thus, similar to the critical power during cycling exercise, the RCP appears to represent a physiological boundary that dictates whether VO
2
kinetics is characteristic of heavy- or severe-intensity exercise during swimming. |
