The objective of this study was to analyze the motor performance of men and women at different rest intervals in multiple sets at 70% 1-RM. Fourteen individuals, seven males (21.5 ± 0.6 years, 76.2 ± 2.5 kg, 176.4 ± 6.4 cm) and seven females (19.6 ± 0.7 years, 66.3 ± 2.1 kg, 163.1 ± 6.7 cm) performed three sets at 70% 1-RM in the bench press and leg extension, with intervals of 60 and 90s between the sets. The factorial ANOVA evidenced significant interaction of set vs. rest interval (F = 17.56, P < 0.001) and the main effect of exercise (F = 7.04, P < 0.021), without differences between the sexes (F = 0.17, P = 0.691). The results suggested that the reduction in motor performance induced by multiple sets at 70% 1-RM is similar in men and women, regardless of the rest intervals between the sets.
