Effect of different intervals between the attempts of the 1-RM test performance in maximum strength in women

Abstract

Test of one repetition maximum (1-RM) is often used to measure the strength of an individual in a given exercise. The purpose of this study was to compare the effect of different intervals between the attempts of the 1-RM test on the maximum strength performance in women on the leg press 45°. Thus, 12 volunteers (19 ± 1 year) resistance exercises to practice at least six months, were submitted to four sessions of testing, alternated by at least 48 hours. The recovery intervals between the attempts of the 1-RM test were 30, 45, 60 and 180 seconds, with order randomly determined. To identify the difference between the intervals proposed was applied to analysis of variance One-way ANOVA (p < .05). The results revealed no significant differences in performance for maximal strength in women, compared to the average values obtained in each test interval. These findings indicate that for maximal strength measure in leg press 45°, intervals less than a minute (30 - 45 seconds) can be used with the same accuracy as longer intervals, providing greater time economy for 1-RM test application.
