Sex differences in rating of perceived exertion in different body-weight resistance exercises

Abstract

Aims: This study analyzed and compared the the rating perceived exertion (RPE) of upper and lower body weight resistance exercises (BWR) performed by men and women. Methods: Forty-eight participants (24 men and 24 women) attended two experimental sessions: an introduction to the BWR and RPE scale and an assessment session to determine the RPE of each exercise. Four dynamic BWR (Lower-limb: Squat and Lunge; Upper-limb: Knee Push-Up and Push-Up) and two isometric BWR (Core: Front and Side Plank) were evaluated. Each exercise's RPE was evaluated using a Borg CR10 scale. Results: Push-up exercises have the highest RPE value (4 men, 10 women) and squat exercise the lowest RPE value (1 men, 2 women). Comparing the RPE’s between men and women, there was a significant difference in the upper-limb exercises (Men: 4; Women: 10; P <0.001). There was no difference in lower-limb (Men: 3; Women: 3; P= 0.991) and core exercises (Men: 3; Women: 3; P= 0.856). Women demonstrated a higher RPE’s than men for the upper-limb exercises, but did not show for higher RPE’s in lower-limb and core BWR. Conclusion: The study provides new evidence for the use of RPE in BWR interventions and suggests that exercise professionals should consider that RPE during BWR is influenced by exercise, sex, and training status.
