Abstract

Objective: To analyze correlation between RPE (Rating of Perceived Exertion)and submaximal 1RM (One Repetition Maximum) on quadriceps femoris muscles of the healthy subject. Design: Cross sectional study. Setting: Physical Medicine and Rehabilitation Laboratory. Subject: Twenty-four students of physiotherapy collage (12 men; mean age 20.33+ 0.98 years; 12 women, mean age 20.83+ 0.83 years). Interventions: All subject perform two trials, first is quadriceps femoris isotonic strength test by EN-Tree pulley 24 kg machine, second is quadriceps femoris isotonic exercise with predetermined submaximal intensity (20%, 40%, 60% and 80% 1RM), each set 2 repetition and 2 minutes resting time between set. First and second trial separates 48 hours minimally. Main Outcome Measures: First trial to measure 1RM (kg) value of right quadriceps femoris muscle, second trial to measure RPE value by Borg Scale 6-20 on each submaximal 20%, 40% , 60% and 80% 1RM load. Artery pulse count by fingertip pulse oxymetry before and after performs second trial. Results: The mean 1RM right quadriceps femoris on men is 20.25+2.73 kg, on women is 11.92+1.44 kg. There was strong and positive correlation (men, coefficient correlation =0.88; woman, coefficient correlation =0.92) between RPE and sub maximal 1RM load on quadriceps femoris. Conclusions: The RPE related to submaximal 1RM on quadriceps femoris muscle isotonic strength. The RPE can use to determine intensity of muscle strength exercise on both men and woman.
