Comparison of the perceived subjective exertion and total load lifted response in resistance exercises performed on stable and unstable platforms

This study aimed to compare the perceived subjective exertion (PSE) and total load lifted in resistance exercises performed on stable platforms (SP) and unstable platforms (UP). Participants were 20 men (24.6 + or - 3.4 years, 179 + or - 0.1 cm, 80.6 + or - 9.1 kg and 11.8 + or - 3.4% fat). Each subject performed a 15 maximum repetition test in half squat exercises (soil and balance discs), pronated barbell row (soil and bosu) and biceps curl (soil and balance discs) in both conditions. PSE was measured using the OMNI-RES scale and the load lifted value (kg). To verify the normality of data, the Shapiro-Wilk test was used. Possible differences related to loads and PSE on the platforms were performed by the paired t test. Significance level of p
