Background: Training towards the goal of improving maximal strength is commonly undertaken; particularly by athletes involved in contact sports, powerlifters, and recreational body builders. Multiple methods of programming exist, with autoregulated (AR) training being a popular topic within the training community. AR training involves day to day fluctuations in volume and/or intensity in order to accommodate the athlete’s performance on a given day. This could potentially allow for greater gains in strength due to fine tuning of the fatigue-fitness interaction. However, scant research exists on AR training, with the vast majority being carried out on individuals during rehabilitation therapy. Aim: To examine whether a load-autoregulated strength training programme is more effective in improving maximal strength in the squat, bench press, and dead lift than a traditionally periodised program, in experienced weight-trained individuals. Methods: Eight healthy, recreationally trained males agreed to participate and completed this study. Each participant completed a traditionally (TD) programme and an AR programme in a randomised, cross-over design with a 2-week wash out period between. Each programme involved baseline one-repetition-maximum testing (1RM) in the barbell squat, bench press, and deadlift followed by eight weeks of training with subsequent 1RM testing. Following warm up, participants completed one set of as many repetitions as possible (AMRAP) at 85% of baseline 1RM, followed by subsequent working sets. 1RM Prediction equations were utilised in the AR training group to dictate load used in the working sets; whereas the TD groups subsequent sets were based on baseline 1RM. Results: The squat, deadlift, and total improved significantly within each programme (all p<0.05), however no differences between programmes were present (all p>0.05). Bench press strength improvement was significantly greater in the TD programme (time x programme interaction p<0.05). Conclusions: The present study found no differences in effectiveness of programmes at producing strength gain in the squat, deadlift, or total weight lifted. However the TD programme resulted in a greater improvement in bench press strength compared to AR. Future research would also involve auto-regulated volume, as well as ensuring matched cross over design, and ideally a use of more trained participants.
