SUMMARY:

Introduction: The one-repetition maximum (1RM) test is
recommended to guide resistance exercise load prescriptions;
however, it may not be safe to use it in individuals undergoing
anterior cruciate ligament reconstruction (ACL-R). Thus, the
rating of perceived exertion (RPE) emerges as a safer and
easier alternative; however, its validity and reliability still need
to be confirmed for this population. Objective: To evaluate the
validity and intra-subject reliability of perceived exertion
scales for monitoring resistance exercise load in individuals
undergoing ACL-R. Methods: This is a cross-sectional study
that will include a sample of 44 individuals who are between
the 13th and 17th postoperative weeks of ACL-R. The
volunteers will undergo a 7–10RM test on the horizontal leg
press and knee extension exercises to predict the 1RM, which
will be performed unilaterally on both limbs. Between 40 and
72 hours later, RPE will be collected through a set of 10
repetitions at 30%, 50%, and 70% of predicted 1RM on
separate days. Each intensity will be repeated once for
reliability analysis. The order of exercises, limbs, and loads
will be randomized. Participants will be blinded to the load
they are lifting and immediately after each set will report their
RPE on the scales. Statistical analysis will include correlation
tests and, if possible, linear regression to validate the use of
the scales in this population. The intraclass correlation
coefficient will be applied to determine the reproducibility of
the responses, and a mean comparison test will be used to
compare RPE between limbs. Expected results: The scales
are expected to be valid and reproducible, enabling their use
in clinical practice to monitor resistance exercise load during
rehabilitation of patients with ACL-R.
