Autoregulation (AR) of training translates to altering parameters of training depending on theathletes daily readiness to perform. Allowing the athlete to progress at their optimal individual pace might be beneficial for increases in maximal strength compared to more traditional forms of periodization, like the linear periodization (LP) model, where the rate of progression is predetermined (PRED) in terms of percentages of the athletes 1RM. In this study, 6 resistance-trained men performed resistance training twice a week for six weeks in an AR or PRED program in terms of progression. For the AR group, progression of load was met when the subject achieved the desired number of repetitions in a given set. For the PRED group, progression of load was made in a linear fashion on a session to session basis, predetermined load progression based on their pre-test 1RM for all 6 weeks. Both groups strived to have 0-1 repetitions in reserve after each completed set, to make sure that the intensity was theoretically the same for both groups. There was no significant differences observed between the groups in terms of absolute strength from pretest to posttest for squatstrength (PRED: 23.3 ± 8.0 kg vs AR: 19.2 ± 12.8 kg; (t= -0.47 (4), p=0.65), bench pressstrength (PRED: 1.7 ± 7.6 kg vs AR: 2.5 ± 4.3 kg; (t= 0.16 (4), p=0.87) or lat pulldownstrength (PRED: 21.7 ± 7.2 kg vs AR: 19.2 ± 10.1 kg; (t= 0.34 (4), p=0.74). There was no significant difference between the groups in terms of body composition changes. The conclusion of this study is that there are no significant differences between AR and PRED for increasing maximal strength or promoting body composition changes.
