Resistance Training with Repetition to Failure or Not on Muscle Strength and Perceptual Responses. JEPonline 2019;22(4):165-175. The purpose of this study was to compare the effect of 8 wks of resistance training with or without failure on muscle strength, total training volume, rating perceived exertion, and estimated repetitions to failure. Eighteen trained men participated in the study. The training was performed for 3 non-consecutive days of the week for 8 wks. The subjects were randomly divided into 2 groups: (a) one group that trained until concentric muscle failure (MAX); and (b) the other group did not reach concentric muscle failure (SUBMAX). Both groups performed 3 sets of 10 repetitions. Muscle strength (1RM) and training load (10RM) were evaluated before (pre), after 4 wks (4W), and after 8 wks (8W). In addition, the total training volume (TTV), the rating perceived exertion (RPE), and the estimated repetitions to failure were verified. The results showed that 1RM and 10RM increased 4W and 8W (P<0.001), but without differences between groups (P>0.05). The TTV was similar between the groups with no significant difference (P>0.05). The RPEmuscle and RPE-overall was higher in the MAX group when compared to SUBMAX group (P<0.01), but the MAX group presented lower values of estimated repetitions to failure (P<0.01). In conclusion, both trainings were effective for increases in muscle strength and training load, but it seems that training to concentric muscle failure can lead to a greater sensation of muscle fatigue.
