This study aimed to estimate the anaerobic workload during intermittent exercise, using critical power (CP) model and manipulating the work and rest periods (30s:30s e 60s:60s), while the work:rest ratio was unchanged. Participants (n=7) cycled exhaustively during four different sessions in order to estimate de CP and the anaerobic work capacity (AWC). The following two sessions, they performed 10 bouts using 30s:30s and five bouts using 60s:60s, with intensity 70% greater than CP. Thereafter, they performed another continuous bout until exhaustion the intensity with known duration to determine recovered and remaining AWC. Blood lactate concentration was also measured throughout intermittent exercise. The 60s:60s protocol induced greater anaerobic workload compared with 30s:30s one, due to there were lower exercise duration (59%), recovered AWC (84%) and remaining AWC (57%) on the former protocol. In addition, blood lactate (66%) and net AWC (38%) during 60s:60s protocol were greater than during the 30s:30s one.Downloads
