Abstract

Research suggests RIR is a valid and reliable method to prescribe and manipulate RT intensities. However, the literature reviewed revealed that a protocol had not been developed or introduced that allows practitioners to educate athletes or recreational populations to implement the RIR scale. Purpose: Thus, this study aimed to develop a familiarization protocol through synthesized research-study findings and evaluate its efficacy in resistance-trained populations.

Methods: Participants were males (n = 9) with > 3 years of RT experience. The study consisted of 5 sessions. Participants performed the bench press and v-squat for four sets each at varying intensities. The PG followed the familiarization protocol, and the NPG was only provided the prescribed intensities and assistance to ensure safety. eeRIR, over and underestimations, and the predicted probability of being accurate were compared across groups to evaluate protocol efficacy. Results: Data analyses revealed the FP was effective in increasing RIR estimation accuracy for the PG. eeRIR was significantly less for the PG (BP = 0.144 repetitions, VS = 0.112 repetitions) when compared to the NPG (BP = 0.953 repetitions, VS = 1.472 repetitions). Additionally, the predicted probability of accurately estimating RIR was significantly higher for the PG (BP = 85.8%, VS = 89.7%) than the NPG (BP = 28.2%, VS = 12.3%) – suggesting the familiarization protocol was effective in increasing RIR estimation accuracy.
