Physiological responses during continuous and intermittent exercise: implications for the aerobic evaluation and training prescription
AbstractThe objective of this study was to review the acute responses to maximal and supramaximal intermittent exercise (intensities near or above maximal oxygen uptake - iVO2max), and also at submaximal intermittent exercise, with intensities near maximal lactate steady state (MLSS). At the conditions of interval training above 100% iVO2max 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 VO2max. 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.
