The objective of this study was to review the acute responses to maximal and supramaximal intermittent exercise (intensities near or above maximal oxygen uptake - iVO(2)max), and also at submaximal intermittent exercise, with intensities near maximal lactate steady state (MLSS). At the conditions of interval training above 100% iVO(2)max with short repetitions (<60 s), the passive recovery between the repetitions allows higher intensity during sets. For longer repetitions, the active recovery can be more efficient, since promotes greater blood lactate removal and longer time near VO(2)max. At the conditions of submaximal interval training, the relationship between intensity and duration of the repetitions are still maintained, i.e., the longer durations (>300 s) allow lower intensities and the shorter (150-300 s) allow higher intensities, with similar metabolic conditions (i.e., MLSS). However, both recovery types can be utilized, since they proportionate similar intensities at these conditions.

The aim of this study was to access the P-t(Lim) model in swimming, applying the load control available in full tethered swim condition. Its physiological meaning for the determination of boundary of heavy/severe domains was assessed from the relationships with critical velocity (CV), critical power (CP) and maximal lactate steady state (MLSS). The velocity at MLSS (v(MLSS) = 1.17 +/- 0.11 m/s) and CV (1.19 +/- 0.12 m/s) were significantly different. Similarly, the power at MLSS (p(MFEL) = 89.2 +/- 15.1 W) and CP (99.4 +/- 22.9 W) were significantly different. There was no difference between lactate concentration at vMLSS (3.54 +/- 0.9 mM) and p(MLSS) (3.76 +/- 0.6 mM). Significant Pearson's coefficients (r > 0.70) were observed among v(MLSS) and P-MLSS with their respective values on time-limited model. Thus, the tethered-crawl condition seems to be valid to determine the boundary of heavy/severe domains, and to access the aerobic capacity of swimmers.
