Our data showed that when the intensity of load and work-to-rest ratio are equal, set configuration defines the SBP response, as was previously suggested . Differences between designs may be a consequence of dissimilar reflex pressor responses  and distinct intrathoracic pressures as a consequence of different needs on the Valsalva maneuver execution . In this sense, despite the fact that we did not analyze the metabolic demands of the protocols, IRDs have a higher concentric velocity (i.e., a shorter concentric TUT), which is negatively correlated with the glycolytic involvement . Since glycolytic involvement determines the reflex pressure response , this suggests that during the IRD, the pressor response from a peripheral origin was potentially reduced in comparison with the CD. On the other hand, an individual repetition produces an excessive intrathoracic pressure in comparison with subsequent repetitions , thus propagating and increasing the momentarily SBP into the next individual repetition, to a greater extent than the CD does.
