ResumoRecently it was observed that two resistance training (RT) protocols performed with 80% of 1 maximum repetition (1RM) or 30% of 1RM until volutional fatigue had the same hypertrophic gains after 10 weeks of training.However, the number of repetitions performed in the protocol with 30% of 1RM is higher as compared to the 80% of 1RM, which leads us to wonder if both protocols can generate the same energy expenditure (EE) during and after the session.In this sense, the purpose of this research was to evaluate the EE during and after two acute RT protocols with same intensity and hypertrophic gains but different volumes.Eleven young male adults (21.82 ± 2.62 yrs; 1.75 ± 0.06 m; 71.80 ± 7.96 kg; 16.91 ± 6.11 % body fat) underwent a crossover design of two RT protocols performed with 30% of 1RM or 80% of 1RM until volutional fatigue.Both protocols were composed by 3 sets of leg extension using the corresponding intensities (30% or 80% of 1RM) until fatigue.Participants were measured for oxygen consumption and peak blood lactate concentration during exercise and 60 minutes postexercise after each bout to determine EE and post-exercise oxygen consumption (EPOC).Also, a control session without exercise and with the same procedures for EE and EPOC was carried out.Significant differences were found for total volume and peak lactate levels.However, no differences were observed for EE between the RT protocols.In conclusion, both protocols (30% or 80% of 1RM) until fatigue can promote the same EE during and after the sessions.
